Product Description

1. Main parameters of electroplating  production line

 

No	Item	Specification
1	material	carbon steel
2	product size range	according to customer
3	coating type	zinc
4	coating thickness	1~30μm

 

2. Technological process of rack electroplating

racking→alkaline degreasing→electrolytic degreasing→water rinsing→pickling→water rinsing→zinc plating→water rinsing→bright dipping→water rinsing→passivation→water rinsing→hot water rinsing→drying→put down

 

3. Main process introduction

 

Alkaline degreasing:remove the oil on the surface of products

Electrolytic degreasing: further remove the oil on the surface of products to ensure the binding force of the coating .

Pickling: remove the oxide from the surface of products and activate the product surface .

Water rinsing: clean the product thoroughly after the tank to avoid mutual contamination of the tank.

Zinc plating: the product is coated with a uniform coating.

Bright dipping:Remove the alkaline film on the surface of zinc layer and increase the brightness of zinc layer.

Passivation:increase corrosion resistance of zinc layer to prevent white rust during transportation.

Hot water rinsing:clean the surface of product and improve the temperature of the proucut itself

5.Solution preparation

Zinc plating solution:

                                   ZnCl₂                           30-70 g/L
                                   KCl                               200-260 g/L
                                   H₃BO₃                         25-35 g/L
                                   Wake up agent            16-25 ml/L
                                   Brightening agent         0-1 m1/L

 

6.Common faults and solutions

Coating blooming (fog)
Possible causes                                                      Solutions
1. Pre treatment with oil                                          1. Strengthen oil removal
2. Poor post-treatment processing                          2. Improvement
3. Excessive organic and metal impurities              3. Major treatment
4. Excessive brightening agent                               4. Electrolysis at low pH
5. Less boric acid                                                    5. Supplement
6. Aging of the dipping liquid                                   6. Replacement
7. insufficient anode area                                        7. Adding multiple anodes
