Mr. Mai is the boss of an electroplating chemical nickel processing factory in Shenzhen, Guangdong.Recently, when Mr. Mai used electroless nickel plating solution, the coating surface of the workpiece after chemical nickel plating is normal, but after hot water washing, the workpiece will be baked in the oven for 10 minutes, and there will be a layer of white water mist on the coating surface.Since the appearance quality of the workpiece is seriously affected, Mr. Mai asked Bigolly engineers to help solve this problem.
According to the on-site experience and the characteristics of the product electroless nickel plating solution Ni-809, Bigolly engineers checked the process flow of the production line and the use of the plating solution, and found no problems.But the engineers found that the cleaning water behind the chemical nickel was too dirty.So the engineer and the operator learned about the replacement frequency of the cleaning water, and the cleaning water was replaced twice a week.
The engineer asked Mr. Mai to explain the condition of the cleaning water, and told Mr. Mai that the three water washes after electroless nickel plating must be replaced every day, every shift if possible, and try to use pure water.The washing water shall be overflow rinsing with a certain flow rate, so as to ensure that the surface of the workpiece is washed clean and solve the problem of water mist.
After Mr. Mai adjusted according to the engineer's suggestion, the water mist on the workpiece surface was solved.Now the coating performance and quality of the workpiece have been improved, and the defective rate has decreased from 8% to below 0.3%, which makes production easier.
Therefore, we should pay attention to this when there is white water mist on the edge of the workpiece coating during the use of electroless nickel plating solution, and replace the cleaning water in time to reduce the occurrence of faults.If you are interested in the electroless nickel plating solution, you can contact the Bigolly customer service for free samples and detailed technical information!
