Coating technology: Wuxi self polishing antifouling coating performance test

Core tips: the test results of the test items are brownish red fineness, μ M80 viscosity, PA · s1.63 drying time, H surface drying, 2 surface drying, 24 impact resistance, cm30 coating amount, g / ㎡ (100 μ m) 460 salt water resistance for 4 years, no blistering, no falling off storage period (12 months) viscosity basically unchanged, and the regular performance of the coating completely meets the general requirements of antifouling coating 1、 Determination of resistance reduction performance The resistance reduction performance is very important for Wuxi self polishing antifouling coating The organic tin antifouling coating with 5-year effect is used as reference Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings: the test results of the test items are brownish red fineness, μ m 80 viscosity, PA · s 1.63 drying time, H surface drying 2, real drying 24, impact resistance, CM 30 coating amount, g / ㎡ (100 μ m) 460 salt water resistance for 4 years, no blistering, no peeling storage period (12 months) viscosity basically unchanged, and the conventional performance of the coating completely meets the general requirements of antifouling coating 1 The measurement of resistance reduction performance is very important for Wuxi self polishing antifouling coating The organic tin antifouling coating with 5-year effect is used as a reference The drag reduction curve o f the disc is shown in the following figure: necttype = "rect" O: extrusio NOK = "F" style = "margin top: 0px; margin right: 0px; margin bottom: 0px; margin left: 0px; padding top: 0px; padding right: 0px; padding bottom: 0px; padding left: 0px; word wrap: break word; line height: 25px;" > the drag reduction curve of the disc has passed the above tests, This one has obvious resistance reduction performance 2 The measurement of abrasion rate is another important index of Wuxi self polishing antifouling coating It determines the antifouling period and effect of the antifouling coating together with the thickness of the antifouling coating Because there is no standard to determine this index, we can only simulate the situation of ship berthing and navigation for indoor measurement As the actual situation is much more complicated, the measured value can only reflect the actual situation when it is combined with the test results of a real ship We apply 2 × epoxy coal tar pitch antirust coating on tinplate cylinder, spray 2 layers of the coating, the total thickness of the coating is 300 μ m, as a sample, install it on the high-speed mixer, and soak it in the water tank filled with natural seawater, rotate it at 15 knots at room temperature, 6-7h a day, and then stand for 17-18h The test time is one year, and the measured abrasion thickness is 32 μ m, that is, the abrasion rate of the coating is 32 μ M / A because of the difference with the actual situation, we can design the thickness of the antifouling coating according to 50 μ M / A 3 The toxicity test can make the coating not pollute the sea water and meet the requirements of environmental protection The toxicity test is particularly important for one Grind the sample to 200 mesh and prepare the required concentration suspension with rapeseed oil The experimental animals were healthy Kunming mice, half male and half female, respectively The results showed that the oral LD50 was more than 10 g / kg, and the dermal LD50 was more than 10 g / kg According to the standard of acute classification of industrial toxicants, the coating is micro toxic by mouth and skin, which is consistent with the theoretical analysis 4 Ship application test ship application test is the most effective and reliable method to inspect antifouling coating The construction performance, compatibility with antirust coating, adhesion of antifouling coating, dry wet alternation resistance and antifouling performance can be tested by the ship test Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
