Electroplating equipment What are the basic process requirements of?

Electroplating refers to the surface processing method of electroplating in a kind of solution containing electroplating metal, which uses the metal of the electroplating substrate as the cathode and deposits the ions of the electroplating metal on the metal surface of the substrate through electrolysis. The coating performance is different from that of the base metal and has new characteristics. According to the function of the coating, it can be divided into protective coating, decorative coating and other functional coatings.

The surface condition and processing requirements during electroplating, the selection of appropriate steps, necessary finishing and processing of the part surface to make the part have a clean surface, is an important link to obtain high-quality electroplating. The main equipment used in the pretreatment process of plating includes grinding machine, polishing machine, brushing machine, sandblasting machine, polishing machine and various fixed grooves. Electroplating is the main process of the whole production process.

According to the requirements of parts, one or more single metal or alloy electroplating processes shall be selected for electroplating or immersion of parts to achieve the purpose of corrosion prevention, wear resistance and beauty. The equipment used in electroplating process mainly includes various fixed tanks, barrel plating tanks, hangers, baskets, etc.

Plating post-treatment refers to polishing, polishing, passivation, coloring, drying, sealing, dehydrogenation and other work for parts, and one or several processes shall be selected as required to make the parts meet the quality requirements. Commonly used post plating treatment equipment includes grinding, polishing, various fixed grooves, etc.

1. There should be good adhesion between the coating and the foundation, coating and coating.

2. The coating shall be fine, smooth and even in thickness.

3. The coating shall have the specified thickness and as few pores as possible.

4. The coating shall have brightness, hardness and conductivity.

5. Plating time and temperature determine the size of plating thickness.

6. The ambient temperature is - 10 ℃~60 ℃.

7. The input voltage is 220V ± 22V or 380V ± 38V.

8. The large working noise of water treatment equipment shall not exceed 80dB (A).

9. The relative humidity (RH) shall not be greater than 95%.

10. The COD content of raw water is 100mg/L~15000mg/L.
