What is electroplating?
Electroplating is the process of plating a thin electroplated film on the surface of metal products using the principle of electrolysis to prevent corrosion, increase hardness, improve wear resistance, electrical conductivity, reflectivity, and enhance aesthetics.
Metal keychains are electroplated in the following colors:
1.Chrome
2.Nickel
3. Pearl nickel
4. Non-lacquered nickel color (commonly known as: white steel color)
5. Silver (generally spray a layer of lacquer oil to protect after plating)
6. Gold, and fine: imitation gold, real gold, ancient gold, platinum, 24K gold, rose gold, champagne gold, etc. (golden plating is usually sprayed with a layer of lacquer oil for protection)
7. Gun color
8. Bronze, divided into: green bronze and red bronze
Basic process of electroplating:
(Polishing) → Hanging → Degreasing and degreasing → Washing → (Electrolytic polishing or chemical polishing) → Pickling activation → (Pre-plating) → Electroplating → Washing → (Post-treatment) → Washing → Drying → Hanging down → Inspection packaging
Electroplating method:
1. Rack plating (generally suitable for large products, products with relatively high surface requirements)
2. Barrel plating (generally suitable for small products, products with low surface requirements)
3. Brush plating (suitable for partial plating or repair)
4. Continuous plating (suitable for batch production of wires and strips)
5. Vacuum electroplating (the metal is heated by electrodes at about 200 degrees Celsius under high vacuum, so that the metal sublimates to produce steam, which adheres to the surface of the plated parts to form a coating. Commonly used metal cadmium and silver powders are commonly used in glass to produce a mirror effect. , Mobile phone lens)
Common bad phenomena in electroplating:
1. pitting
2. Shakong
3. Bubbles
4. Peeling
5. Discoloration
6. Burning edges
7. Blackening
8. Lu Bai
9. Dew copper
