energy-efficient lighting: LED industry 2010-03-03 09:37 to revive the economy after the crisis, so that an energy saving, environmental protection the theme of the Industrial Revolution began quietly in the world, but to develop economic power LED industry has become the unanimous choice of . Zf countries attach great importance to the LED lighting industry,shopfittings, have launched semiconductor lighting program, and has formed a worldwide encirclement of semiconductor lighting technology breakthroughs trend. As the zf a powerful impetus, LED lighting market expanded rapidly, while the zf a result of the enterprise together, LED lighting is the wave of popularity has been quietly off. Global LED output in 2009 is expected to substantial growth of 15.7%, to reach 8.677 billion U.S. dollars. With the TV, computer, automotive, interior LED lighting uses the growing demand in the global LED market will grow rapidly in 2010 the market size is expected to reach 12.3 billion U.S. dollars. China, in 2010 the domestic LED lighting and its related industries and will also be more than 150 billion yuan. The size of the world’s fast-growing LED lighting market is expected to grow to 2015 over 5 billion U.S. dollars. Contrast to the world’s five LED giant grew up, South Korea, Seoul Semiconductor (Seoul) The rise of merit our serious consideration: policy to foster the domestic market’s growth will lead to good LED industry groups in the capital markets broken cocoon. “The semiconductor industry views on energy-saving lighting” will be LED industry rise to the national strategic level, will boost consumer spending power LED industry to accelerate the release of strong market demand. We expect the popularity of LED lighting in the pace of the fourth quarter of 2009 is bound to speed up. LED industry, the investment strategy themes: (1) The right has a core technology, performance expectations for better-defined strategy of the leading enterprises in configuration, the preferred 3-an optical (600,703), Linkage Optoelectronics (600,363), Fong A (000055), coal gasification, (000,968), Zhejiang Sunshine (600,261), German-ho Yun (002,005); (2) camera configuration Long Electric Technology (600,584), with the party shares (600.1 thousand), Hangzhou Silan Microelectronics (600.46 thousand), Furi Electronics (600,203) and other enterprises with industrial advantages; (3) an active interest in the potential energy release of the industry chain with companies, such as Foshan Lighting (000541), Xiamen Xindeco (000,701), deep Konka (000016).

in the adhesive joints subject to tensile stress, there are three different methods of joint force. (1) The tensile stress and the plastic junction perpendicular to each other and through the plastic junction centers evenly distributed across the bonding surface, the stress uniform tensile stress, tensile stress is also known. (2) The tensile stress distribution across the bonding surface, but the force was non-uniform distribution of such a situation is called non-uniform stretch. (3), compared with the non-uniform stretch, its force action line is not a poke cushion sample center, and biased towards one end of the specimen; its force plane is not symmetric, but asymmetric, this stretch called street light the asymmetric stretch, it was sometimes called street light the tearing away from this pilot testing or split testing, to show differences with the stripping phase. 1. Tensile strength test (bar and rod) is also known as tensile strength test tensile strength test or even pull away from the strength tests. 1. Principles of sticky material from the two rods are composed of butt joints, their plastic junction and the vertical axis of the specimen, the tensile force transmitted to the vertical axis through the specimen until the adhesive junction damage to unit bonding area of the bear The maximum load to calculate the tensile strength. 2. Instruments and equipment tensile testing machine should be able to guarantee a constant tensile speed, destruction of load should be selected dial 10% -90% capacity range. Tensile machine response time should be short to not affect the measurement accuracy, should be able to fracture the specimen measured at the time of the failure load, the measurement error of less than 1%. Tensile testing machine should be loaded with the specimen axis and loading direction is consistent, and automatic fixture in the stretch. Curing fixture, can exert a fixed pressure to ensure proper bonding and positioning. 3. Test step (1) the trial bar and the sample for the test stick with the provisions of the shape, size of the rod-like being sticky material. Specimens for the two test rods glued through a certain process conditions made the device under test. Unless otherwise specified, the test bar size in Table 8-4. The sample size of their choice depending on the strength of adhesive under test, tensile machine full-scale, trial bar itself, as well as test the strength of yoga material environmental factors. Table 8-4 cylindrical test bar with a square size of test bar diameter and side length b / mm a / mm diameter / mm L / mm plastic junction surface roughness Ra / um 10 ± 0.1 15 ± 0.1 25 ± 0.1 50 ± 0.1 10 1,215,155,799,304,550 50 0.8 0.8 0.8 0.8 for the test processing of metal rods and 45 # steel, LY12CZ aluminum alloy, copper, H62 brass and so on. Non-metallic materials such as laminated plastic. Laminated products test rod and its laminated plane should be parallel with the test bar one side and try to stick on the pin hole should be perpendicular to the plane with the lamination. Test rod surface treatment, coating and the sample preparation process, should be consistent with product standard requirements. Good bonding the specimen to a little circle of thin plastic around the stems is appropriate at this time do not have clear, For more than clear plastic, they should be after curing. (2) test in the normal state, the metal specimen to the test from the sample preparation is completed between the minimum parking time is 16h, up to 1 month, non-metallic specimens parking for at least 40h. Sample test environment should be parked for more than 30min, it would be installed street light in the tensile testing machine fixture, test their destructive capacity, the electronic tensile machine testing machine should enable the specimen (60 ± 20) s in damage; sometimes mechanical tensile machine is used 10mm/min drawing speed. 4. The results of evaluation test results to five specimens indicated that tensile strength of the arithmetic mean, take three significant digits. Should also be a note of the damage for each specimen type, such as interface failure, cohesive failure within the adhesive layer has been destroyed and mixed sticky material damage. 5. Influencing factors (1) stress analysis of adhesive bonded joints are perpendicular to the surface stress, the stress distribution of shear stress to be uniform over much, but according to theoretical speculation and stress distribution of tests confirmed that the edge connector in the stretch There are also stress concentration. To confirm this, some people use a certain thickness of the rubber bonding adhesive in the sample in place and found the specimen in tension, rubber significant contraction in the middle. In the joint statement is affected by tensile stress, shear stress is concentrated in the sample adhesive – air – is viscous body of the three largest border, that is the stress at this point most concentrated. If we are bonding cylindrical dislocation after two and a half large, then the axis of the specimen loading direction deviated from the centerline, which is often happen. Then, there is a split of stress, leaving the edge of stress concentration increased dramatically. When the boundary stress reaches a critical value, the layer edge cracking occurred, crack rapidly expanding to the entire bonding surface. The specimen from the tensile stress distribution analysis showed that the bonding specimen size and modulus, layer thickness, modulus of adhesive joints affect the size of the edge of the stress distribution coefficients and, therefore, is bound to affect it The strength values. And tensile-shear specimen, like loading speed and the sample temperature also affects the tensile strength. (2) The sample sizes of different diameter, the tensile strength test samples the value of different, and the discrete large-scale, the same diameter and the sample its maximum for more than 50% higher than the minimum. On the square sample, due to the different distance from the edge to a central point, that stress distribution is more uneven, so the sample can only be measured with the square to the “approximate” the tensile strength values. (3) layer thickness on the tensile strength, with the layer thickness increases, it reduces the adhesive joint strength. The thinner the layer, the greater the intensity. Theoretical studies predict that, for the very thin adhesive layer, butt tensile strength inversely proportional to layer thickness; while for very thick layer, it has nothing to do with the thickness of plastic, such as polyethylene wax (molecular weight 2750) to adhesive bonding steel and steel, when the layer thickness of 150nm, the joint tensile strength is close to polyethylene wax about their own strength of 5.5MPa; while the layer thickness of 5nm, the butt joint is the adhesive strength of 2 times its own strength. Other factors, such as modulus, temperature on the tensile strength and tensile shear strength of similarity. 2. Inhomogeneity inhomogeneous tensile test tensile test is characterized by the role of tensile stress lines Although the passing of the sample center, but when the bonding force plane stress distribution is uneven. Uneven stretching joints are often used in the aviation industry as a bonding structures, such as aircraft wing skins and wing ribs, long-heng of the bonding, the bonding helicopter rotor working conditions such as major withstand tensile stress, And in most cases is uneven work under conditions of tensile stress, and therefore determined the uneven adhesive joints and tensile strength of a certain practical significance. Determination of non-uniform tensile strength under a certain extent, reflect the adhesive toughness and, therefore, can reflect a variety of adhesive bonding materials on the stress concentration sensitivity of the seam. This method reference to GJB94-1986. Principle by a rigid metal block and a thick flexible foil is sticky material consisting of glued butt joints, in the non-uniform tensile load to bear when the damage until the specimen. The unit length of the maximum load to bear on the calculation of non-uniform tensile strength. 1. Instruments and equipment tensile testing machine specimen special fixtures 2. Test step (a) Sample and sample preparation and technical conditions in accordance with the provisions of the adhesive specimen glued to form a sample. Try curing after (23 ± 2) ℃ for at least 16h to place only after stretching. Tension must be cleared before I glue. (2) test a pilot project (23 ± 2) ℃ manner. In the air relative humidity (50 ± 5)%. If it does not meet the above conditions shall be indicated in the report. Measurement of bonding at the specimen width, accurate to 0.01mm, the average measurement results obtained on both sides. Tensile machine clamps the sample into its clamping at both ends of the distance between (200 ± 1) mm, and to ensure that the edge of the sample thick blocks were clamped at both ends of the distance to the difference is not greater than 0.5mm . To 5-15mm/min speed loading, until the damage. 3. The results of evaluation test results of the calculation to three significant figures. To 5 sample test results as the arithmetic average of test results, take three significant digits. Its standard error S, dispersion coefficient of CV should also be reported. Dispersion coefficient and the standard error of two significant figures. 4. Influencing factors (1) the thickness of the flexible yoga material is sticky and the flexible clamping was sticky material from the different thickness and gripping from the test results can not be compared. As the plate thickness increases, uniform tensile strength increase; Similarly, the specimen clamping at both ends to shorten the distance, and its tensile strength increases unevenly. (2) The adhesive nature of the adhesive elastic elongation of the size of the mold and uneven impact on tensile strength. This is the relationship between the middle is more complex. Typically, the increase in elongation at break, lower elastic modulus of adhesive, so that the edge of the phenomenon of stress concentration has improved, so non-uniform tensile strength increases. But when the adhesive modulus of elasticity to reduce its cohesive strength is also reduced accordingly, would reduce the tensile strength of non-uniform. Elongation and the modulus is a contradiction, how just right to use this contradiction to improve the adhesive joints uneven tensile strength, is the need for adhesive formulation development nowadays some effort. (3) The layer thickness as the layer thickness increases, the joint stress concentration decreased non-uniform tensile strength increase, but the layer thickness continues to increase, due to the internal defect layer increases, the intensity changes for the worse. (4) Test non-uniform temperature tensile strength and test temperature. Under different temperature adhesive modulus also changed, leading to changes in stress distribution in adhesive layer; another temperature, it changes the intensity of cohesion, two factors interact in a certain test temperature range, it may be the emergence of a less obvious peak. (5) The geometry of the specimen width of the joint tensile strength of the uneven impact of small, but the bonding part of the length of the specimen that is rigid and flexible plastic specimen then the shorter the length, then the intensity of the smaller. 3. Asymmetric tensile tests (splitting tests) asymmetric tensile test, also known as split testing, testing out the strength of it is called splitting intensity. In the GB7749-87, as well as abroad ASTMD1062 and JISK6853 provided in both asymmetric tensile test method. 1. Principles of the sample for the docking structure. In the sample applied with adhesive plastic junction junction perpendicular to the edge of the tension measured when the sample was separated to bear the greatest load per unit width of the bonding force that it required the separation of the splitting strength. 2. Instrument and equipment requirements with the tensile strength testing machine test requirements. Rally machine chuck moving speed (5 ± 1) mm / min. 3. Test sample preparation steps in accordance with the provisions of adhesive technical conditions. Piece of metal and plastic junction should be formed, there should not be bent, twisted in a grimace and other deformation. There should be no hair gel junction mouth, edge-preserving right angles. Material for LY12CZ aluminum or 45 # steel. Specimen clamping fixture shall be automatically adjusted with the device so that the load force to make the role of the vertical line and the sample plastic junction test sample preparation to a minimum time of 16h, up to 1 month. Test should be (23 ± 2) ℃ under standard temperature, if the test temperature, humidity, demanding trial or arbitration, it should be at a temperature (23 ± 2) ℃, relative humidity of 45% -55% under the test, if only a requirement temperature, then the sample temperature in a standard parking 0.5h, if the required standard test environment should be at a temperature (23 ± 2) ℃, relative humidity of 45% -55% within the park at least 16h. Activate the pull machine to (5 ± 1) mm / min loading speed of loading, record the maximum load the specimen splitting damage and damage type and percentage of plastic parts. 4. The results of assessment for each adhesive at least five samples taken for testing to the minimum, maximum and average as the test results, and its value to take three significant digits. 5. Influencing factors used in metal processing test block for semi-hard temper brass, hard temper copper phosphor copper, aluminum and cold-rolled street light steel tempering. Right asymmetry in tensile strength, due to the overlap length of the specimen, it has a very significant impact. The shorter the specimen length L, the smaller the tensile strength of asymmetry. Such as temperature, layer thickness, adhesive properties of the same intensity and glass. 4. Cross-lap tensile strength test specimen with cross-lap specimen, also known as cross-shaped specimen, it tests the tensile strength of uniform tensile strength. Specimen using metal plates and strips. Before the test surface with the caliper measurement of length and width of the overlap layer. The specimen will be installed in the tensile testing machine with the dedicated carry out tensile test, tensile speed of 10mm/min, up until the destruction layer. Each sample should not be less than 5, take the arithmetic mean as the test results, to allow deviation (± 15%), to retain three significant digits. 5. Tensile strength test (bacteria-like sample) 1. Principles of tilting by the two bacteria constitute a docking connector, its plastic junction and the vertical axis of the specimen, the tensile strength through the specimen longitudinal axis spread adhesive junction until the destruction of the unit bonding area of the maximum load calculation to withstand tensile strength. 2. Instruments and equipment tensile testing machine requirements and of the same type and rod-like tensile test, and should be equipped with a special clamping device, fixture should be able to autoyoga matic positioning, allowing the specimen axis with the center line imposed by gripper pull in the same direction. Room temperature should be maintained temperature (23 ± 1) ℃, relative humidity (50 ± 2)%, if it is mainly the temperature, allowing the sample in a desiccator, in the dryer below the partition containing calcium nitrate saturated solution, fixed on the surface at 23 ℃ when the humidity was 51%. Related to temperature and constant humidity data can be found from the Handbook of Chemistry. 3. Test step (a) Preparation of sample specimen material can also be used with metal timber, which selected according to different adhesive requirements. One of the metal with cold-rolled street light steel, semi-hard temper brass, hard temper copper, 2024 aluminum alloy, phosphor bronze, magnesium alloy and the low hardness of nickel silver. For metal bonding, each of adhesives should be tested at least arbitration test 10 specimens, routine testing of not less than five. Metal specimen, surface treatment, adhesive ratio, the amount of glue, glue the number of drying time and curing conditions should be set according to relevant provisions of the manufacturer. Used when bonding fixture should ensure that proper bonding and precise specimen positioning. (2) test before the test sample should be (23 ± 1) ℃ for state regulation, not less than 16h. The sample into the upper and lower clamping devices, such as high temperature testing, should be directly measured with the thermocouple outside the bonding area of metal surface temperature of the sample. If the indirect measurement of the response to temperature and equilibrium time be amended. The specified temperature holding time of not less than 10min, temperature control accuracy of 100 ℃ Following is ± 1 ℃, 101 ℃ for more than 1%. The sample to test temperature balance of the time, less than or equal to the 50-100 ℃ for 30min; 101-200 ℃ less than or equal to 45min; less than or equal to the 201-300 ℃ for 60min. The following gripper moving speed 10mm/min tensile specimen, until the damage, record the greatest damage type of loading and specimen damage. 4. Influencing factors on Bonding Strength of bar and rod-like factors and the same tensile strength tests. After the bonding layer average thickness require control within 0.0254 m. And the adhesive thickness should be specified measurement method. Different standards for different bacteria-shaped specimen dimensions shown in Table 8-5.

Lamborghini’s Been Extremely Forthright In Their Mission To Release A New Car Yearly And With The LP550-2 Balboni Making Headlines Earlier This Month, it Begs The Question – Will We See An LP550-2 Superleggera?
The Saint A’gata Bull Pictured Above Is Not The LP550-2 SL, rather A Gallardo Superleggera Fitted With The Newer LP560-4 Front Bumper. Seeing This Made Us Wonder If We’ll Get A Light Weight Track Star Based On The Current Car. We Could See Lamborghini Offering This As A Regular Production Model To Replace The LP550-2 Balboni When All 250 Of The Limited Edition Cars Are Sold Out, but What Would Change Between The Two Models? Would Its Appearance Be As Striking As The Recently Reveamr16 Murcielago LP670-4 SV With Its Massive Wing Or Would It Be A More Subdued Track Rat?
Time Will Tell Whether This Will In Fact Happen, but The Significant Investment Involved In Producing A RWD System For A Run Of 250 Cars Doesn’t Seem Like The Greatest Financial Decision. We Can Only Hope. Image Credit: Oskar Bakke ViaTeamSpeed

2008-02-22 08:27 Source: PUWORLD released into the exclusive forum for
1. form a good bonding surface treatment
one of the conditions is necessary to deal with the substrate surface is sticky
surface dust, grease, etc. There is often a weak interface layer, its influence, built on the weak interface layer of the adhesive bond strength obtained is not easy to increase the surface tension that does not yoga match with the adhesive surface of the substrate, but also the need for chemical treatment of the surface of treatment is to improve the adhesive strength of one of the first steps
2. cleaning degreasing
plastic substrate surface of some metals are often susceptible to dust and oil pollution Khan In addition, there are plastic surface release agent, so such a plastics and adhesive layer to form only a weak bonding interface in terms of the polyurethane adhesive, metal or plastic surface oils and poor compatibility with the polyurethane, while the presence of water with the adhesive in a bubble reaction NCO groups, so that glue and substrate surface area reduced, and so reduce the cohesion of adhesive layer, thus bonding surface before cleaning and drying treatment is generally surface-active agents containing alkaline cleaning with organic solvents, and then washing drying, or organic solvents (such as the acetone, carbon tetrachloride, ethanol, etc.) directly to clean metal in general have the rust first with sandpaper wire brush to remove surface rust
3. rough treatment
normally be carried out on the smooth surface rough treatment, in order to increase the plastic the contact area with the substrate adhesive penetrate the substrate surface, concave clearance, or pores, curing late-coming “nail hook stick”-like inlay fixed role and can stick firmly to the substrate with methods commonly used in blasting Wood File coarse sanding and other adhesives, but is too rough on the surface of the infiltration would be affected, easy to residual cavity or produce bubbles, but will reduce the bonding strength If you use methods such as sanding and easy to damage the substrate, it should adopt the coating at the end of glue etching methods such as corona treatment to change their surface properties to make it susceptible to polyurethane adhesive bonding
4. Metal surface chemical treatment
for metal surface can be skimmed at the same time a slight rust corrosion treatment, the treatment agent can be a lot of are generally acidic treatment fluid such as aluminum alloy, available potassium dichromate / concentrated sulfuric acid / water (mass ratio of about 10/100/300) mixture, at 70-12 ℃ dipping 5-10min, washing, neutralization, and then washing, drying of iron available
concentrated sulfuric acid (hydrochloric acid) with water 1:1 mixture at room temperature dipping 5-10min, washing, drying or potassium dichromate / concentrated sulfuric acid / water mixture processing
5. Plastic and the rubber surface chemical treatment
most polar plastics and rubber only on the surface roughening treatment and solvent degreasing treatment, but a very low surface energy of polyolefins, such as chemical methods can be used to increase the surface polarity, there is solution oxidation Corona oxide flame law
(1) chemical treatment liquid can be used potassium dichromate / concentrated sulfuric acid / water (mass ratio 75/1500/12, or 5g/55ml/8ml ratio, etc.), PP or PE in the 70 ℃ dipping 1-10min or 1.5h at room temperature after soaking, washing, and washing in dry
(2) dealing with the high-frequency high-voltage corona discharge, so that plastic surface partial oxidation with air oxygen to produce carbonyl groups such as polar Several surface treatment methods are often combined, such as sanding corrosion → washing → drying →
6.’s primer
order to improve the adhesive properties may have been handpar38 well in the substrate coated with a layer of very thin primer (Primer), primer can be handpar38 just stick to protect the surface from erosion and pollution, to extend the storage time
polyurethane adhesives and sealants commonly used in primer are: polyurethane varnish (such as the polyurethane adhesive or paint dilute solution); multi-isocyanate adhesive (such as the PAPI dilute solution); dilute solution of organic silicon coupling agent; dilute solution of epoxy resin, etc.
7. adhesive preparation
one-component polyurethane adhesive generally did not require preparation, operational requirements can be used directly, this is a single-component adhesive for ease of use of two-component or multi-office
-component polyurethane adhesive, shall require the preparation of instructions if they know of the hydroxyl content components and isocyanate-based content, the distribution ratio of each group can be determined by chemical calculation, isocyanate index R = NCO / OH is usually in the 0.5-1.4 range in general, two-component solvent-based polyurethane adhesive with adhesive, the two sets of distribution ratio tolerance degrees larger than the non-solvent, but if the gum in the NCO group with too much excessive, then the cure is not complete, and the curing of the adhesive layer of hard, even brittle; if excessive hydroxyl components more, then the layer low-viscosity adhesive strength of soft cohesive poor solvent-free two-component adhesive ratio of the tolerance of the smaller than the solvent-based, it is because the initial molecular weight of each component smaller, if one component of excessive, then the result in slower cure and difficult to complete, the surface layer sticky low intensity
has deployed a good glue should be run out of days is appropriate, as dubbed in the plastic for a limited period after the period of application of adhesive that is formulated to maintain its operational timing of sticky With the increasing degree of placement time, which are difficult to place until the glue gel to lose mobility and failure of different varieties of grades of polyurethane adhesive period of application of different, ranging from minutes to days on a large-scale use in industrial production, the should be applied in advance to do Phase I trials
if the adhesive contains the catalyst components, or in order to accelerate the curing rate of incorporation of the catalyst with glue, then apply to shorter In addition, the ambient temperature a greater impact on the period of application of the summer for a short period of winter long through the urethane-level organic solvents diluted two-component polyurethane adhesive, apply to the general period may be extended two-component solvent-based adhesives, such as, soft-plastic composite film with two-component polyurethane adhesive, application period should be greater than 8h (that is, a days)
if they could ever use the same day with a good adhesive, can be properly diluted, and the cover closed and the shade store, the next day at work to check for varying turbidity or gel phenomenon, if the glue was no significant change in appearance good fluidity, it can still be used against the person is generally a small number of new batches of the gel if it has been assigned deterioration, it should be discarded to
order to reduce the viscosity, easy to operate, so that glue coating evenly, and is conducive to control of sizing the thickness of the organic solvents can be added to dilute the polyurethane adhesive can be used are acetone, methyl ethyl ketone of diluent such as toluene ethyl acetate
addition of catalyst can speed up the rate of curing catalyst for curing adhesives are generally organic tin compounds
8. bonding construction
1. gluing
coating (glue) methods are spraying brushing dipping roller coating, usually according to the type of plastic viscosity and production requirements and decided, the key is to ensure uniform layer No bubble gum
adhesive without missing the amount of (in fact, with the layer thickness) also affect the shear strength of an important factor, usually the higher the shear strength within a certain range if the layer is too thin, then the adhesive can not fill the substrate surface, uneven gaps, leaving vacancies in bond strength is low when the layer thickness increased, decreased bond strength is generally believed that the load of lap-shear specimen, they were sticky layer structures and their deformation, plastic layer has been damaged as – kinds of spin-off state, the role of peel strength of the shear strength reduces the apparent value of
2. dry home
for solvent-based polyurethane adhesive, the adhesive coating, after a good take home a few minutes to dry tens of minutes, so that most of the volatile solvent adhesive, which will help improve the tack to be properly heated when necessary, to carry out the blast drying (such as the composite film lamination process) or else, due to a large number of solvent left in the gel, curing easy to layer in the process of the formation of air bubbles and affect the quality of adhesion for solvent-free polyurethane adhesive, the adhesive after the adhesive material can be fit
3. bonding
this step will have been painted over rubber material is sticky adhesive surface fit together, can also use a fixed bonding fixture parts, to ensure a perfect fit-adhesive surface positioning, if necessary, to put some pressure on the adhesive to better produce plastic flow to infiltration by stick surface, so that maximum adhesive contact with the substrate surface
9. adhesive curing
when the majority of polyurethane adhesive in the adhesive does not immediately have a high adhesive strength, still needs to cure the so-called lamp curing refers to the liquid adhesive into a solid process and curing process also includes post-ripening, that is, after the initial curing adhesive that can be reaction of groups for further reactions or generated by the crystallization and obtain the ultimate strength for the cured polyurethane adhesive, the curing process is to glue the base of NCO Mission complete reaction, or to complete solvent evaporation crystallization of polyurethane molecular chain, so that the substrate adhesive with high adhesion to generate sufficient process of polyurethane adhesive can be cured at room temperature for reactive polyurethane adhesive, if the room temperature curing will take longer time for the plus catalyst for curing in order to shorten the curing time, heating method of heating can be used not only conducive to the curing adhesive itself, but also help speed up the glue in the NCO group and the substrate surface of the active hydrogen group-phase reaction can be heated so that layer softening, in order to increase the infiltration of the surface of the substrate and facilitate the molecular motion, resulting in the bonding interface of molecular forces to find a “partner” heating benefit in improving adhesion of a two-component polyurethane adhesive for bonding steel plate, time at different curing temperature when the adhesive strength of the heating methods are
curing oven, or bake Road, drying room heating, heating and other fixtures for the heat and quickly heating the metal substrate can be used fixtures, layer heat faster than the oven heating ” br> heating process should be to gradually warming is appropriate solvent-based polyurethane adhesive should pay attention to the solvent evaporation rate during dry home, most of the volatile solvent has been lost, the remaining solvent slowly spread outward through the adhesive layer, if the heated faster then the solvent to soften the adhesive layer in the gasification of the bubbling, the formation of air bubbles in the joints, serious most of uncured adhesive was extrusion flow of visco-state joint, the foryoga mation of vacancies will affect the bond strength for the two-component solvent-free adhesives and single-component moisture-curable adhesives, heat can not be too fast, otherwise the NCO groups with glue or substrate surface moisture in the air to accelerate reactions in which the proliferation of CO2 gas too late, while the layer viscosity increased rapidly , air bubbles remain in the layer in the
one-component moisture-curing polyurethane adhesive mainly rely on air moisture curing, so the air humidity should be maintained, and are advised to slow curing at room temperature is appropriate if the air is dry, a small amount of water can be a flat on the coating surface in order to promote curing if the adhesive were trapped was dry and hard in between the sticky equipment material, and the thick layer, the interface and the outside water can not penetrate plastic, then easy to cure is not complete, this case can inject a very small amount of plastic water

Now is the winter and the cold solar terms, prevention of influenza in patients with psoriasis people used the warm coat wrapped around the body’s cold, but the delicate facial skin, even coated layer after layer of moisturizing lotion, lips are still is chapped bear. Psoriasis sun Well, for, psoriasis patients, dry lips that should be how should we do?
Hospital, Shijiazhuang, skin experts have warned that the emerging, high incidence of psoriasis in winter season, if his face has psoriasis, dry air is let the already fragile skin worse, so the patient must be good friends usual health and care. A regular massage massage lips lips
method is not difficult, as long as before go to bed every night, take a cotton pad and dip some honey, painted lips, then gently massage with the fingers in order to help promote blood circulation, make lips get Oxygen, increasing nutrition, lips can become nourished.
2, in particular, often wear masks
psoriasis bicycle, wearing surgical masks to block out cold wind, the purpose of wearing masks is very simple, the lips in order to maintain temperature and humidity, to avoid missing water and dry.
3, olive oil and paste, powdered milk before going to bed
smear in patients with psoriasis can be coated in olive oil before going to bed will be absorbed in the lips for more than 20 minutes, then wipe, but also a small amount of milk into a paste of water transfer shape, thickly painted lips act as a lip membrane.
4, lip skin of psoriasis patients to use scissors
dealing with tilt of the lips skin, can be a small scissors carefully cut the mirror, do not hand or pliers to tear, so as to avoid tearing the lips , leading to pain, bleeding, and even infections, but medical calls where the “dangerous triangle.”
5, the correct use of lip balm
lip balm should be used when the lips a healthy, if his lips had begun peeling, and it should stop using it.
In addition, psoriasis patients should always eat more fruits and vegetables, fresh fruits and vegetables to add body needs both nutrients, but also can effectively improve the body’s immunity, thereby preventing the occurrence of diseases in winter.

adhesive types and development direction of urea-formaldehyde glue used in wood processing, due to formaldehyde emission urea-formaldehyde glue in the high, wood-based panels has flood light to pollution of the environment, according to the National Testing Center of the determination of wood-based panels, at present the majority of our man-made board formaldehyde emission were 30mg/100g above, much higher than the national standards promulgated by the GBl8580-2001. Now a lot of urea-formaldehyde glue manufacturers are actively improving the process and formula, to increase formaldehyde trapping agent method, do everything possible to reduce the formaldehyde content to make it at or below the national standard. Some production is small, the low level of production technology, poorly equipped workshop-type enterprises, unable to meet national standards can only be eliminated.
polyvinyl formal (ie, 107 gum)
is mainly used for interior wall paint, decoration, wallpaper and cement enhancer and so on, through the determination of the vast majority of the 107 rubber content of free formaldehyde were 10 ~ 50g/kg, the state enacted a mandatory standard GB18583-001 (formaldehyde is less than 1g/kg) 10 ~ 50 times, GB18583-001 standard enforcement, will result in many small and medium sized manufacturing plant and township 107 rubber stop middle-class or converting. In the future will be completely free of formaldehyde “interface agent” or other adhesives to replace, from Beijing and other places the use of terms, the interface agent not only has the production of simple and good adhesion of the advantages of plastic 107, but prices and 107 glue is almost the same, is a worth promoting environment-friendly adhesive.
neoprene and the SBS rubber
neoprene (commonly known as all-purpose adhesive), mainly used for interior decoration, decoration, wood processing, bags and footwear industries, widely used, the market demand is strong. CR contains a large number of volatile organic solvents. At present, the neoprene used in more types of organic solvents, but the total can be divided into low toxicity and non-toxic solvent, such as ethyl acetate, 120 gasoline, acetone, etc., toxic type and toxicity of a larger solvent such as benzene , toluene, halogenated hydrocarbons, etc..
toxic solvent benzene larger in Europe, America and Japan and other developed countries already prohibit the use, but in our country because of its cheap, there are still many manufacturers to use, according to the National Quality Inspection Center, the determination of adhesive, a number of chloroprene plastic products, high levels of benzene 104g/kg, toluene content of 300 ~ 500g/kg, serious pollution of the environment and harm the health of consumers. The state enacted a mandatory standard GB18583-2001, blocked for interior decoration with benzene as the solvent of the neoprene, and toluene and total volatile organic compounds has also made a strict limit.
At present, many manufacturers in adjusting the product mix, and some with SBS to replace the neoprene rubber, SBS rubber will have a larger growth, it is worth noting that some manufacturers in the production of SBS rubber, the use of highly toxic The halogenated hydrocarbons as the solvent (such as: 1,2 – dichloroethane, dichloromethane, etc.), which will create new harm to consumers.
