Common knowledge of coating: what is the function of antirust paint? What are the commonly used antirust knees

Core tip: in many cases, a layer of antirust primer should be applied before finishing coat The benefits are obvious Therefore, our steel barrel enterprise is better able to do the same when conditions permit In fact, many steel barrel customers have put forward such requirements The role of antirust paint is to prevent metal rust and increase the adhesion of the coating After the metal is painted with antirust paint, it can effectively isolate the contact between metal and air, and the antirust paint can passivate the metal surface, prevent the chemical or electrochemical reaction between other substances and metal, so as to play the role of metal antirust In addition, due to antirust paint and 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: in many cases, before painting the top coat, always apply a layer of antirust primer, the benefits are obvious Therefore, our steel barrel enterprise is better able to do the same when conditions permit In fact, many steel barrel customers have put forward such requirements The role of antirust paint is to prevent metal rust and increase the adhesion of the coating After the metal is painted with antirust paint, it can effectively isolate the contact between metal and air, and the antirust paint can passivate the metal surface, prevent the chemical or electrochemical reaction between other substances and metal, so as to play the role of metal antirust In addition, due to the reaction between antirust paint and metal surface, metal passivation layer is formed, so the combination between paint and metal has chemical binding force besides physical binding force, so the adhesion of paint to metal is particularly strong Commonly used anti embroidery paint has the following: 1 Red lead antirust paint this is a kind of paint mixed with red lead and dry oil It has good permeability and wettability, soft paint film, strong adhesion, but slow drying In addition, because the red lead ratio is large, it is easy to precipitate, and it will become thick if stored for too long, and the brushing performance is poor 2, iron and red phenolic antirust paint is made of anti rust pigment and long oil phenolic resin or lacquer material When used, it should be mixed with about 10-30% loose perfume Its adhesion is good, and it will not bite off because of the softening of the top coat 3 Iron red alkyd antirust paint is prepared by adding iron lead, chrome yellow and other pigments into alkyd paint, filler, solvent and drier Good adhesion, strong rust resistance, high hardness, elasticity, strong impact and nitro resistance This kind of antirust paint is most suitable for the priming of external paint in our steel barrel industry It is not only suitable for the priming of general external paint, but also suitable for the priming of nitrocellulose paint and amino baking paint, especially after baking, its performance is better 4 Zinc yellow antirust paint is made of pure phenolic paint and zinc chrome yellow pigment It has strong adhesion and high resistance to the marine environment 5 The gray antirust paint is made of lead zinc oxide as the main antirust pigment and varnish It has excellent performance of rust prevention and atmospheric erosion resistance, but its dryness is slow Suitable for painting outdoor steel components 6 The main film-forming material of the transparent paint is polyurethane resin, which can react with water in the air to form a film or bake to form a film This kind of coating has the properties of moisture-proof, salt fog proof and mildew proof, and the transparency, brightness and appearance of the coating are good 7 There are many kinds of other antirust paint, such as barium metaborate antirust paint, zinc ash antirust paint, epoxy antirust paint, mica iron oxide antirust paint, perchloroethylene antirust paint and so on Their performances are different, which are not introduced here 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,
