Coating knowledge: definition of antirust coating and analysis of product types

Core tip: antirust coating is a kind of coating which can protect metal surface from chemical or electrochemical corrosion of atmosphere, sea water, etc Coating antirust coating on the metal surface can effectively avoid the direct invasion of various corrosive substances in the atmosphere, so as to maximize the service life of the metal It can be divided into physical and chemical Antirust Coatings The former relies on the proper combination of pigment and paint to form a dense paint film to prevent the invasion of corrosive substances, such as iron red, aluminum powder, graphite antirust paint, etc.; the latter relies on the chemical anti rust effect of antirust pigment, such as red lead, zinc yellow antirust paint, etc Used for rust prevention of bridge, ship, pipeline and other metals Type of antirust coating 1 Red Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Home of coatings: antirust coating is a kind of coating that can protect metal surface from chemical or electrochemical corrosion such as atmospheric and sea water Coating antirust coating on the metal surface can effectively avoid the direct invasion of various corrosive substances in the atmosphere, so as to maximize the service life of the metal It can be divided into physical and chemical Antirust Coatings The former relies on the proper combination of pigment and paint to form a dense paint film to prevent the invasion of corrosive substances, such as iron red, aluminum powder, graphite antirust paint, etc.; the latter relies on the chemical anti rust effect of antirust pigment, such as red lead, zinc yellow antirust paint, etc Used for rust prevention of bridge, ship, pipeline and other metals The type of antirust paint 1 Red lead antirust paint is a kind of paint mixed with red lead and dry oil It has good permeability, wettability, soft film, strong adhesion, but slow drying In addition, the red lead ratio is large, easy to precipitate, and it will become thick if stored for a long time, 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 anti rust ability, high hardness, elasticity, and impact resistance This kind of antirust paint is most suitable for the priming of external paint in the iron can 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, mildew proof, transparency, high brightness and good appearance There are many kinds of antirust paint, such as barium metaborate antirust paint, zinc ash antirust paint, epoxy antirust paint, mica iron oxide antirust paint, perchloroethylene antirust paint, 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,
