The bright nickel layer on stainless steel is a silver-white metal with yellow light. Its hardness is higher than copper, zinc, tin, cadmium, gold, silver and so on, but lower than chromium and rhodium metals. Bright nickel has high chemical stability in air and good stability to alkali. The specific steps are as follows:

Organic solvent degreasing → chemical degreasing → washing → cathode electrolysis activation → flash nickel plating → washing → activation → washing → bright nickel plating → washing → passivation → washing → washing → hot water washing → shake drying → drying → acceptance.

In recent years, there are many kinds of brighteners in the solution of stainless steel bright nickel plating. To sum up, the development of brighteners has experienced four years. The first and most original product is saccharin plus butanediol. It can be plated with bright nickel with high levelness. Its use flourished in the 1960s and 1970s. But as a result of butynediol instability in nickel plating tank, life is short, organic impurities accumulated quickly, need to deal with nickel tank often, so by epichlorohydrin or epoxy propane branches of acetylene with butyl glycol, the synthesis of the second generation of nickel plating brightener, such as BE, 791 brightener, things have improved, and 791 reserves have alkynyl, then progress will pyridine polymerization, Formed the third generation of products, faster light speed, less brightener dosage, longer service life. Now further use of nickel plating brightener intermediate a variety of combinations of new brightener has been developed to the fourth generation of products. It uses less, produces light faster, takes longer processing cycles, and has a stronger ability to deep coat.
