二手单螺杆造粒机组高精密锌钙磷酸磷化处理产品详细

Iron oxideSilver powder, the of points is 53.62. It is difficult to combines with water. But can and acid type solvent unifies in together. It is two kinds of properties of steel oxidation product. The types of oxide, he used as a also different. The result is bad oxide physical surface contains many sundry, may lead to etch layer has a transparent phosphating film in water treatment, after lead to big yellow. Do phosphating solution when had better choose effect high oxide (purity or less than ninety-nine percent, direct production out). The purity of iron phosphating hydraulic according to different re, to choose a different oxide. Make the other component does not change, change the oxidation five purity, can improve the of the phosphating liquid. Improve the 2 g oxidation material can reduce the phosphating solution acidity, which in turn would increase a lot. Phosphating solution to add new ion the phosphating film become delicate, than manganese ion is much better. Acid agent Sulfuric acid score is 103.55, the density of 1.475. The use of sulfuric acid because it contains a certain amount of sundry display light yellow, strong corrosion resistance and water absorption performance. Mixed with water rapid response, and at the same time release a lot of heat. And the ratio of water after the sulfuric acid should be slowly down the hydraulic and colleagues constantly stir evenly. Can and a lot of metal, metal antioxidant reaction get salt composition. Sulfuric acid to phosphate coating and phosphate layer has the following influence Phosphate fluid in micro a small amount of sulfuric acid, in a sort of sense can increase the phosphate layer thickness and corrosion performance, the main reason is the reaction of sulfuric acid can improve phosphating of speed.
