We know that in the copper-nickel-chromium plating process, there are often a variety of failures, in which the poor bonding of the plated layer is a plater often encountered, then, this issue of the article we will discuss the use of alloy chemical degreasing powder, what are the things need to pay attention to, so as to ensure that the bonding of the plated layer is good.
Electroplating is a physico-chemical process that utilizes electrolysis to form a uniform, dense, and well-adhered coating on metals, alloys, or other conductive materials. During the plating process, the cleanliness of the surface of the workpiece is directly related to the quality of the plating. Especially, electroplating degreasing process is one of the key steps to ensure the quality of electroplating.
In the process of using zinc-nickel alloy natural color passivator, when there is a problem with the passivation film, such as blue passivation film, is this caused by the problem of passivator? Actually, it's not. Maybe it's the plating solution.
Mr. Tu from Wenzhou, Zhejiang Province is the owner of a processing plant that processes plastic plating and multi-layer nickel plating. Recently, Mr. Tu found that the palladium activation working solution he used in the production process would produce more hydrochloric acid fog. Considering that the acid fog would pollute the environment and harm human beings, Mr. Tu wanted to find a colloidal palladium water without acid fog.
Why is the coating binding force still poor after plastic coarsening? In fact, this is related to the state of the plastic matrix. In this issue, we will discuss what is the meaning of the poor state of the plastic matrix? And how it causes poor coating adhesion in plastic electroplating process.
Mr. Shen from Jiangsu Province, is the owner of an electroplating factory engaged in acid galvanizing processing of various hardware parts. Recently, in the production process of using black zinc passivator, Mr. Shen found that the corrosion resistance of the black zinc workpiece after sealing is very poor, the workpiece is basically white rust after 24 hours of salt spray test, and the sealing film is easy to fall off, the customer can not accept such a workpiece. However, Mr. Shen extended the drying time of the workpiece, but there was still no improvement. The above Mr. Shen wants to search the Internet to see how this situation should be solved.
