Plating pretreatment process in electroplating process occupies a very important position. The main materials used in the electroplating of copper and copper alloy, stainless steel parts, zinc alloy die castings, steel parts. The number of materials required by different pretreatment methods according to the material, especially zinc alloy die casting, once before the treatment is not good it is easy to produce blistering, peeling, there are mainly two kinds of pretreatment methods commonly used:
Pretreatment of chemical method: after the parts are installed, they are directly immersed in concentrated sulfuric acid. The temperature of sulfuric acid is from 0 to 0 DEG C, and the time depends on the surface state of the parts. Low temperature, surface polishing wax significant, dipping time should be longer. It should be noted that sulfuric acid solution can not be brought into the water.
Physical pretreatment:
Take the sandblasting method before plating processing, the concept of sandblasting machine is the air driven sand material grinding surface, sandblasting occupied a pivotal position in the electroplating process, main function is to the workpiece surface impurities and oxide eliminated, so that the surface area increases, improve the adhesion of the coating and coating quality can also improve; in the evacuation of residual stress in the structure, reach the surface hardening of the workpiece, add parts on behalf of plastic deformation and fracture resistance, and the workpiece surface compressive stress occurs, the progress of fatigue strength; make the workpiece surface defect with mechanical damage reduction, decrease the stress concentration and so on.
Sand blasting machine blasting process strengths:
The utility model is characterized in that the utility model is characterized by a physical reflection, sandblasting treatment, and the foundation of the whole machine is not damaged, and the dimensional accuracy can not be changed;
Part of the surface is not contagious, abrasive and parts of the material for the chemical reaction;
Sandblasting machine can easily handle grooves, concave and other difficult to contact the site, a variety of abrasive particles can be selected applications;
Deal with the cost of reducing the sand blasting machine, the main body of the original sandblasting machine to improve the working efficiency, can be satisfied with a variety of surface finishing requirements;
Low energy consumption, cost saving;
Sandblasting machine does not pollute the environment, eliminating the cost of environmental management.
Sandblasting machine style different sandblasting machine manufacturers are likely not the same, but the working principle is the same, such as Renteng sandblasting machine produced by blasting equipment at all, is inhaled sandblasting, namely the use of compressed air in a negative pressure generated in the spray gun in high-speed flow, the cyclone storage tank respectively. Abrasive tube suction gun through the sand, and then with the flow of compressed air by high speed jet nozzle to the workpiece surface, achieve the sandblasting processing target. In working condition, the compressed air and sand mixed edge side jet, the compressed air to get adequate application, air flow and sand flow is easy to adjust, can get the illusion of energy and sand material mixture ratio, less cost, and high efficiency in practical research, electronics, aircraft, motorcycle accessories, hardware, chemical the surface of the workpiece processing industry liquidation.
