Coating classification: self swimming paint

Core tip: Introduction: self swimming paint, its official name is automatic deposition coating, also known as chemical deposition coating or acid deposition coating The self swimming paint consists of synthetic resin emulsion, metal activator, hydrogen fluoride, hydrogen peroxide and other oxidizing agents and pigment dispersions The immersion coating is 5%-10 of the above composition %The pH value of the aqueous dispersion is 2.5-3.5, and the coating (iron) is immersed in the above coating solution The metal iron dissolves into Fe2 + due to acid, and then is oxidized to Fe3 + by the oxidant Fe3 + neutralizes the emulsion into an unstable state, and quickly settles on the metal surface 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: Introduction: self swimming paint, its official name is automatic deposition paint, also known as chemical deposition paint or acid deposition paint The self swimming paint consists of synthetic resin emulsion, metal activator, hydrogen fluoride, hydrogen peroxide and other oxidizing agents and pigment dispersions The immersion coating is 5%-10 of the above composition %The pH value of the aqueous dispersion is 2.5-3.5 The coating (iron) is immersed in the above coating solution The metal iron dissolves into Fe2 + due to acid, and then is oxidized to Fe3 + by the oxidant Fe3 + neutralizes the latex into an unstable state, and quickly accumulates on the metal surface to form a film The film thickness can be controlled by controlling the immersion time Self swimming paint is a new type of water-based paint, the coating method is similar to that of electrophoretic paint Film forming mechanism: self swimming paint is generally made up of water-based dispersion of organic polymer, pigment, auxiliary agent, etc during deposition, chemical reaction materials, such as fef3, HF, H2O2, etc., which are automatically deposited, are added to the tank solution During coating, the coated workpiece is immersed in the paint bath, HF and fef3 corrode the surface of the workpiece, in which part of the dissolved Fe reacts with the resin, the resin and pigment precipitate and deposit on the surface of the metal workpiece to form a wet film, and the rest which does not react with the resin is oxidized by the oxidant in the bath solution to form fef3 stable bath solution The chemical reaction formula is as follows: dissolution reaction: Fe (workpiece) + 2hf → Fe2 + + H2 (g) + 2F -, Fe (workpiece) + 2fef3 → 3fe2 + + 6F -; oxidation reaction after film formation: Fe2 + + resin → Fe resin, 2fe2 + + H2O2 + 2hf → 2fe3 + + 2H2O + 2F -, 2fe3 + + 6F - → 2fef3 Features: the main features of self swimming paint are as follows: ① water is used as dispersant, no organic solvent, no heavy metal, and the VOC content is very low, so it is a kind of environmental protection paint with excellent performance; ② the matching performance of self swimming paint with primer and finish paint is good; ③ the self swimming paint is chemical reaction rather than electrodeposition, so the paint is uniform without edge effect; ④ There is no dead angle in the self swimming paint coating, as long as the parts can be contacted, good paint film can be achieved; ⑤ the self swimming paint coating equipment is simple, covering a small area, without phosphating treatment; ⑥ the self swimming paint coating saves human resources, high production efficiency, and reduces costs Construction: coating process, application scope of self swimming paint equipment: self swimming paint has been applied to thousands of products, especially for anti-corrosion and surface treatment of metal products such as automobile primer, automobile accessories, agricultural machinery and its accessories, hardware accessories, mechanical equipment accessories, etc 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,
