This specification stipulates the environmental risk level of Shenzhen electroplating enterprises and the evaluation index system of environmental risk level division. This specification applies to the environmental risk classification of enterprises engaged in electroplating operations in Shenzhen (except for enterprises engaged in the manufacture of printed circuit boards). Enterprises engaged in surface treatment such as…

Features (1) The deposition rate of the plating solution is fast and the stability is good; (2) The coating thickness is uniform, the corrosion resistance is excellent, and the corrosion resistance in seawater is better than that of copper and nickel-phosphorus alloys; (3) The coating has high microhardness and strong wear resistance. Usage and usage:…

Features (1) The 4f electron of rare earth neodymium is not tightly closed to the nucleus, and its shielding coefficient is smaller than other internal electrons with the same principal quantum number, so it has a larger effective nuclear charge and shows a strong adsorption capacity . When they are added to the plating solution…

In the case of chemical degreasing or strong acid etching, the large pieces that are hung in one piece can be directly handled by a single hook. Baskets are usually used for smaller workpieces. After processing in the baskets, rack plating, screen spread plating or drum barrel plating are used instead of rack plating. The…

The purpose of electroplating post-treatment is to ensure the quality of the coating and improve the protective, decorative and functional properties of the coating. Post-plating treatment is very important, but it is often overlooked. In actual production, it often breaks down, and even the previous work has been exhausted. Therefore, relevant personnel should pay attention…

Characteristics: This product has low environmental hazard, stable process, simple plating solution components and easy operation, and can be stored for a long time after preparation. The plating solution does not emit acid mist during the working process, and the current efficiency is high. The plating layer obtained from the plating solution has no microcracks…

Features: (1) Electricity nickel plating has less components, easy operation, and good plating brightness. (2) The use of this plating solution solves the problem of poor dispersibility of nickel-phosphorus alloy coatings (that is, the problem of leakage plating in the low flow density area). (3) It has excellent corrosion resistance. The coating obtained by using…
