| The main purpose of pickling passivation treatment is to pickling and passivate stainless steel, to clean up all kinds of dirt, such as oil stains, rust, oxide skin, welding spots, etc. After treatment, the surface becomes uniform silver white, which greatly improves the corrosion resistance of stainless steel. Various types of stainless steel parts, plates and equipment. The surface of stainless steel workpieces treated with stainless steel pickling passivation solution ZJ-302 will produce a bright and beautiful silver-white passivation film. This passivation film is dense and beautiful, and the anti-corrosion potential can be increased by more than 500mV. At the same time, the stainless steel pickling passivation solution has the characteristics of simple operation, convenient use, economical and practical, and at the same time, it adds high-efficiency corrosion inhibitors and fog inhibitors to prevent over-corrosion and hydrogen embrittlement of metals, and inhibit the generation of acid fog. It is especially suitable for small and complex workpieces, not suitable for paste application, and is superior to similar products in the market. And its usage is based on the material of stainless steel and the severity of the oxide scale. It can be used with the original solution or diluted with water in a ratio of 1:1~4; ferrite, martensite and austenitic stainless steel with low nickel content ( Such as 420, 430, 200, 201, 202, 300, 301, etc.) after dilution, the austenitic stainless steel with higher nickel content (such as 304, 321, 316, 316L, etc.) is soaked in the original liquid; generally at room temperature or heated to 15 Use after ~30 degrees, soak for 5-15 minutes or longer (the specific time and temperature are determined by users according to their own trial conditions), until all the dirt on the surface is cleaned up and becomes a uniform silver-white color, forming a uniform and dense passivation film. After the treatment is completed, take it out, rinse with clean water, and then rinse with alkaline water or lime water for neutralization. Ningbo Gaoxin Electroplating provides pickling passivation treatment, electro-galvanizing (blue-white zinc/black zinc/color zinc), zinc-nickel alloy, anodizing, hard oxidation, conductive oxidation, color oxidation and other services.
