Mr. Zhang is the owner of an electroplating factory in Taizhou, Jiangsu. Their company is mainly engaged in the production and processing of galvanized hardware accessories.The galvanized trivalent chromium blue passivator used in his production line has always had a problem, that is, the hole of the workpiece is prone to whitening and fogging, and the corrosion resistance is relatively poor.
Mr. Xu has a large-scale electroplating factory in Guangzhou, and his production line is mainly engaged in the production and processing of chemical nickel plating on plastics.Recently, Mr. Xu encountered a problem. The customer has a PI plastic with poor adhesion after electroless nickel plating, and he has tried several electroless nickel plating additives from different manufacturers, but the results are not satisfactory.
Mr. Xu is the boss of an electroplating factory in Chaozhou. His production line is mainly engaged in the production and processing of electroless nickel plating of small parts.Recently, the workpiece produced by the electroless nickel plating additive used by Mr. Xu has the problem of yellowing, which will affect the appearance and performance of the workpiece.
Mr. Fu's company is a tin electroplating factory in Shenzhen that processes electronic products.The workpieces they produce need to have good welding performance, otherwise it will directly affect the electrical conductivity and service life of electronic products.Recently, the workpieces produced by Mr. Fu using matte tin plating additives have problems such as insufficient white appearance and weak welding of the tin plating layer.
In daily life, many iron workpieces are easy to rust, and after using electroless nickel plating solution to deposit chemical nickel layer, these workpiece iron materials have the ability to prevent rust,some will not rust after a few years.
We all know that in the process of using alkaline galvanizing additives to galvanize hardware, it is necessary to analyze and adjust the concentration of zinc and alkali in the bath in time to ensure that the coating has good performance.Such as dispersing ability, depth ability and corrosion resistance.
