Surface treatments include: chemical pre-treatment surface shaping, degreasing, to embroider, phosphate, passivation. 1) Most plastic surface angle grinder to grind. 2) skimmed is degreased metal surface. The purpose is to increase the film adhesion, drying properties, rust resistance and service life. Degreasing solvent cleaning, alkaline cleaning. For small parts and other mainly alkali immersion degreasing. 3) rust: The aim is to make the film has strong adhesion, chemical and mechanical descaling rust points. Mechanical descaling also includes manual processing, blast treatment and flame treatment. Spray rust mainly sand-blasting, the blasting our normal production equipment, mainly for large-scale structure rust spraying equipment, and for a small, thin-walled workpieces with caution to prevent deformation of the workpiece and fragmentation. So, for small pieces using chemical descaling ie acid rust. But pickling rust environmental pollution is very serious spiral spraying equipment recycling, the EPA's process need to be certified before they can be put into operation later. 4) oxide, phosphate, passivation: To improve the corrosion resistance of the workpiece and the strengthening of chemical rust paint film adhesion, leaving the metal surface to form a protective film, called chemical transformation of metal surfaces. Small parts for industrial machinery mainly phosphate treatment. Namely the use of phosphoric acid or phosphate processing manganese, the process of obtaining phosphate coating layer (phosphate coating) of iron, zinc, cadmium phosphate solution treated metal products. By phosphate treated metal surface, the film adhesion and corrosion resistance is greatly enhanced. Pre-treatment equipment before spraying station processing unit surface treatment equipment, the principle is the use of mechanical erosion accelerate chemical reactions to complete the process of spraying equipment paint room accessories, degreasing, phosphate, cleaning. A typical steel spray pretreatment: pre degreasing, degreasing, washing, washing, surface treatment, phosphating spraying equipment wood drying equipment, washing, washing, pure water. Pre-treatment can be applied to a simple structure Abrator for serious rust, no oil or less oil steel. And water pollution.
