In our daily production process, some large workpieces or workpieces with complex shapes will cause uneven thickness of the coating due to uneven current distribution during the process of nickel electroplating.At this time, we can use this medium phosphorus electroless nickel plating additive to solve the problem of uneven thickness of the coating.
During this time, Mr. Hu used a matte tin additive introduced by a friend, but the production requires a large current density (other process parameters are normal), and the coating of the workpiece is relatively rough, loose, and brittle.This seriously affects the performance requirements of this USB plug-in.
Mr. Shen is the owner of an electroless nickel electroplating factory in Nantong, Jiangsu.Some time ago, due to the poor corrosion resistance and wear resistance of the workpiece coating after one of the customer's automotive switch parts was plated with medium-phosphorus chemical nickel, the workpiece had a short service life and was always complained by customers.So Mr. Shen wanted to find a medium-phosphorus electroless nickel plating solution with good corrosion resistance and wear resistance of the coating.
Mr. Liu is the owner of a galvanizing factory in Weihai, Shandong. His production line is mainly for galvanizing of hardware.Since the customer's requirements for the workpiece are not high, the appearance quality of the workpiece produced by Mr. Liu using alkaline galvanized brightener is average, but it can barely meet the customer's needs.However, since last month, the coating of Mr. Liu's galvanized workpieces appeared bright and dark, which seriously affected the production quality.
Mr. Zhou's company is a Shenzhen company engaged in the galvanized processing and production of nut workpieces.His nut workpieces are mainly used in automobiles, electronics and toys, so they need to have high performance requirements.Some time ago, due to the needs of customers, the workpiece needs a brighter galvanized layer, and the passivation film of the workpiece will appear peeling after color passivation.So Mr. Zhou wanted to replace a trivalent chromium color passivator that is not easy to release.
Mr. Lin's company is the owner of an acid galvanizing plant in Wuxi, Jiangsu.Recently, the screw fittings produced by Mr. Lin will always turn black at the thread position after galvanizing, and the problem has not been solved after the plating solution treatment.So Mr. Lin asked the supplier to solve the problem of the plating solution as much as possible, while looking for an acid galvanizing additive that is not easy to blacken.
