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.
Mr. Wu's company is a company engaged in the production of mechanical equipment and electroplating.They have relatively high requirements on the coating of the workpieces produced, and the bearing workpieces they have recently produced have poor adhesion of the coating after using electroless nickel plating solution.The potion supplier went to the site to adjust the plating solution several times, but the adhesion of the workpiece coating was still very poor and could not pass the adhesion test.
When we use alkaline galvanizing additives for production, the supplier's after-sales service attitude is poor or they can't rush to the scene to solve the problem quickly, which will greatly delay the production time and reduce production efficiency.
Mr. Luo's factory is galvanized for small hardware parts. Many workpieces are to be galvanized and color passivated, and they have the appearance of hexavalent chromium color passivation.However, in the face of the constraints of environmental protection policies, the use of hexavalent chromium color passivators for galvanized is prohibited, and Mr. Luo has to use galvanized trivalent chromium color passivators.
