The key points are as follows: 1 Rainbow coating formulation (mass) component (mass) polyvinyl alcohol 900 carboamide (> 95%), 90 hydrochloric acid, caustic soda, formaldehyde (37%), 333 water, 10000 methyl methacrylate 12 Rainbow coating production process (1) Put the water into the hydrochloric acid reaction tank, raise the temperature to 60 ℃, start the mixer, add polyvinyl alcohol while stirring, and keep the temperature at 95 ~ 98 ℃; (2) After polyvinyl alcohol is completely dissolved, lower the temperature slightly to 85-90 ℃, and add hydrochloric acid, 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 Paint Home News: 1 Rainbow paint formula dosage (mass) dosage (mass) polyvinyl alcohol 900 carboamide (> 95%) 90 hydrochloric acid, caustic soda, formaldehyde (37%) 333 water, 10000 methyl methacrylate 12 Rainbow paint production process (1) Put the water into the hydrochloric acid reaction tank, raise the temperature to 60 ℃, start the mixer, add polyvinyl alcohol while stirring, and keep the temperature at 95 ~ 98 ℃; (2) after the polyvinyl alcohol is completely dissolved, lower the temperature slightly to 85 ~ 90 ℃, add hydrochloric acid, adjust the pH = 1.5 ~ 2, add methyl methacrylate, stir for 30 ~ 40min, add carboamide while lowering the temperature; (3) When the temperature drops to 40-45 ℃, add 10% caustic soda solution, adjust the pH value to 7-8, filter with 40 mesh sieve, and leave the filtrate for 12 hours 3 Coating performance: Rainbow coating is non-toxic, tasteless, non radioactive, non polluting, with strong adhesion, flame retardant, acid and alkali resistance, color fastness, and non cracking It can spray a variety of flower patterns of various colors, and the finished product is low Suitable for interior decoration 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,
