Phosphating line features: This product is a zinc manganese nickel multi phosphating treatment equipment, is the choice of metal coating pretreatment. It is widely used in automobile, railway, electric vehicle, bicycle manufacturing, machinery manufacturing, steel door, steel window, instrument shell, high and low voltage electrical equipment, cabinet shell and other steel structure workpieces for phosphating treatment before painting, paint baking, plastic spraying, rust prevention, electrophoretic dip coating and anti-corrosion treatment of oil pump nozzle. The phosphating film is dense and uniform. The quality of the coating is good, the appearance is gray, and the phosphating film surface has no gray and white phenomenon. Because of the existence of manganese salt, it has the characteristics of good corrosion resistance, so the phosphating film formed by this product has strong adhesion with the substrate, and remarkable corrosion resistance and impact resistance.
