There are some large and small grooves in the whole electroplating line. People who come into contact with them for the first time will ask, what are these grooves and what is their use?

To this end, Manufacturer of electroplating wastewater treatment equipment I have sorted out several common process grooves for you. I hope it can be helpful to you.

1、 Hot stripper

1. Main ingredients: degreasing agent.

2. Function: remove grease and other dirt on the surface of the substrate.

2、 Roughening trough

1. Main ingredients: sulfuric acid, chromic acid.

2. Function: It can form pores on the surface of the product, which is easy to absorb, reduce pitting, and avoid insufficient adhesion and failure.

3、 Sensitizing tank

1. Main ingredients: palladium acid, hydrochloric acid, stannous chloride.

2. Function: adsorb palladium ion on the surface of the product to reduce overflow and leakage.

4、 Degumming tank

1. Main ingredients: sulfuric acid.

2. Function: remove some substances from the previous tank, and reduce the overflow and leakage of plating.

5、 Chemical nickel bath

1. Main ingredients: sodium hypophosphite.

2. Function: make the surface of the product conductive, reduce the overflow, leakage and pitting.

6、 Copper pyrophosphate tank

1. Main ingredients: ammonia, coke copper, coke potassium.

2. Function: The product surface is coated with phosphor copper to reduce burning and pitting.

7、 Copper sulfate tank

1. Main ingredients: sulfuric acid, copper sulfate, chloride ion.

2. Function: The product is plated with copper to reduce burning and pitting.

8、 All optical nickel tank

1. Main ingredients: nickel sulfate, boric acid, nickel chloride.

2. Function: The product is plated with nickel to reduce pitting and burning.

9、 Hexavalent chromium bath

1. Main ingredients: chromic acid, trivalent chromium, acid radical.

2. Function: The product is plated with chromium to reduce burning white and pitting.

10、 Water washing tank

1. Main ingredients: degreased water, hard water, pure water.

2. Function: make the product clean and convenient for inspection and use. The water washing tank is called the multi tank.
