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 isdifficult to combines with water. but can and acid type solventunifies in together. it is two kinds of properties of steeloxidation product. the types of oxide, he used as a also different.the result is bad oxide physical surface contains many sundry, maylead to etch layer has a transparent phosphating film in watertreatment, after lead to big yellow. do phosphating solution whenhad better choose effect high oxide (purity or less thanninety-nine percent, direct production out). the purity of ironphosphating hydraulic according to different re, tochoose a different oxide. make the other component does not change,change the oxidation five purity, can improve the of thephosphating liquid. improve the 2 g oxidation material can reducethe phosphating solution acidity, which in turn would increase alot. phosphating solution to add new ion the phosphating filmbecome delicate, than manganese ion is much better. acid agentsulfuric acid score is 103.55, the density of 1.475. theuse of sulfuric acid because it contains a certain amount of sundrydisplay light yellow, strong corrosion resistance and waterabsorption performance. mixed with water rapid response, and at thesame time release a lot of heat. and the ratio of water after thesulfuric acid should be slowly down the hydraulic and colleaguesconstantly stir evenly. can and a lot of metal, metal antioxidantreaction get salt composition. sulfuric acid to phosphate coatingand phosphate layer has the following influence phosphate fluid inmicro a small amount of sulfuric acid, in a sort of sense canincrease the phosphate layer thickness and corrosion performance,the main reason is the reaction of sulfuric acid can improvephosphating of speed.
