Acid phosphate steel prices | local (certified) | acid phosphate steel

 Seamless steel pickling and passivation passivation technique is the last chemical cleaning process step acid phosphate steel prices, is a key step, its purpose is to materials against corrosion. After the boiler reactor and other equipment by pickling rinse water rinse, the metal surface is very clean, very activated, it is susceptible to corrosion, it must be passivated immediately after cleaning the metal surface to form a protective film, slow corrosion. Full equipment pickling passivation treatment to remove all kinds of oil rust spots and other dirt oxide acid phosphate welding steel pipe market, the surface becomes silvery white uniform after treatment, significantly high corrosion resistance of stainless steel, suitable for various types of steel Stainless steel sheet parts and equipment. Pipe Co., Ltd., Shandong Liaocheng Grenada professional seamless steel passivation treatment of large enterprises. Pickling and passivation reason: Since the potential of zinc is lower than iron, galvanized seamless steel from corrosion when the etching medium, the first zinc iron corrosion protection. Especially after galvanizing chromate passivation layer after layer of bright and beautiful generate passive film, not only significantly improve the protective properties of zinc coating, but also improve the appearance of decorative galvanized parts. Therefore, the zinc coating is widely used in many fields of industrial machinery, electronics, instrumentation industry and light industry and the like. Zinc coating under atmospheric conditions of seamless steel tubes for anodic coatings, passivation after color, significantly improve the protection performance of coatings and improves the appearance. Seamless steel pipe used to prevent corrosion, its low price acid phosphate coating steel pipe manufacturers, excellent corrosion resistance, wide application volume. Zinc is an amphoteric metal, lively, little rain in dry atmospheric corrosion of zinc slower rate, about 0.3 micron / year; electrochemical corrosion in wet industrial atmosphere it with sulfur dioxide, carbon dioxide, oxygen, water, etc. , the corrosion rate of up to 5.3 m / year. People often see the surface of the zinc layer "frost" or "white hair" is the galvanized layer of corrosion products. It also will accelerate the corrosion of galvanized layer if a certain corrosive and can be volatile organic gases in contact with organic materials. The study, a variety of coatings, plastics, rubber materials, insulation materials, wood, paper, adhesives, resins and other organic material, and some can release zinc, cadmium plating highly corrosive acid and acetic acid. Tests showed that when the concentration of formic acid atmosphere> 2.5ppm, acetic atmosphere> 0.5ppm significant corrosion of zinc. When formic acid and acetic acid phosphate mixed steel, zinc corrosion will be greater. Continuous galvanizing layer was thinner after etching, which not only the appearance of the coating is damaged, and even loss of seamless steel substrate protection. If the zinc coating in chromic acid solution consisting of certain passivation treatment, the galvanized layer on the surface layer of tissue dense, high corrosion resistance chromate film (ie passivation film) formed, can significantly improve the corrosion resistance of zinc coating.
