Coating classification: conventional anticorrosive coating and heavy anticorrosive coating

Core tip: anticorrosive coating, generally divided into conventional anticorrosive coating and heavy anticorrosive coating, is an indispensable coating in paint Conventional anti-corrosion coating is a kind of anti-corrosion coating that can protect the service life of non-ferrous metals under general conditions and plays an anti-corrosion role on metals; heavy anti-corrosion coating is a kind of anti-corrosion coating that can be applied in relatively harsh corrosion environment and has a longer protection period than conventional anti-corrosion coating 1 It can be used under harsh conditions and has long-term anticorrosive life Heavy anticorrosive coating can be used for more than 10 or 15 years in chemical atmosphere and marine environment, 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 Coating home news: anticorrosive coating, generally divided into conventional anticorrosive coating and heavy anticorrosive coating, is an indispensable coating in paint coating Conventional anti-corrosion coating is a kind of anti-corrosion coating that can protect the service life of non-ferrous metals under general conditions and plays an anti-corrosion role on metals; heavy anti-corrosion coating is a kind of anti-corrosion coating that can be applied in relatively harsh corrosion environment and has a longer protection period than conventional anti-corrosion coating 1 It can be used under harsh conditions and has long-term anticorrosive life In chemical atmosphere and marine environment, heavy-duty anticorrosive coating can be used for more than 10 or 15 years, even in acid, alkali, salt and solvent medium, and under certain temperature conditions, it can also be used for more than 5 years 2 Thick film is an important mark of heavy anticorrosive coating The dry film thickness of general anticorrosive coating is about 100 μ m or 150 μ m, while that of heavy anticorrosive coating is more than 200 μ m or 300 μ m, and there are 500 μ m ~ 1000 μ m, even up to 2000 μ M According to the American NACE standard [pr-01-76 (1983) modified version of itenno.53105, the corrosion resistance of zs-711 coating was evaluated The results showed that it successfully passed the test of 4000H salt spray test and 4000H damp heat test The coating has excellent weatherability, anti-aging, radiation resistance, abrasion resistance, impact resistance, high temperature resistance (400 ~ 600 degrees C), low temperature (-60 C), and stable conductivity Its resistivity can meet the requirements of antistatic and ensure the long life of the coating 3 Strong adhesion: the coating has strong adhesion to the substrate, and the coating composition contains hydroxyl (- OH) The metal matrix provides positive ions, which can form chemical bond With the help of coupling agents in the coating, the covalent chain can be even realized Under the maintenance of space network structure, the metal, metal oxide nano materials and rare earth oxide nano powder contained in the coating composition help the coating form a dense interface transition layer, so that its comprehensive thermodynamic properties match with the matrix 4 High efficiency and convenience: the construction is simple, and the self curing of inorganic coating at room temperature is realized When the ambient temperature is 20 ℃ and the relative humidity is less than 85%, the surface drying lasts for 15min and the actual drying lasts for 2h, which can ensure the high efficiency of construction, and realize the excellent salt fog resistance and aging resistance The coating is self repairing, the local scratches caused by external force can still be protected, the coating is not damaged by cutting and welding, and the welding with coating does not affect the welding quality 5 Flexible use method: inorganic polymer anticorrosive coating can be used alone or as anticorrosive low-layer coating and organic paint matching When single-layer inorganic polymer anticorrosive coating is used as primer, it can be used with epoxy system, acrylic acid system, polyurethane system, chlorinated rubber system, asphalt system and other surface paint matching, with strong adhesion 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,
