This process is a new type of alkaline barrel plating process without cyanide and chelating agent. It can provide users with many advantages, including flat coating, better zinc usage, easy handling, and tolerance to scorching of the coating.
This process is not containing the CN - and novel alkaline chelating agent of the barrel plating process. It provides a number of advantages for the user, including coating formation, it is a good zinc utilization, easy to operate, and tolerance for the burnt plating layer.
Suitable for barrel nickel plating process for products with complex shapes such as watches, iewelry, hardware accessories, etc.
It can be directly plated on the bottom layer of stainless steel, copper, nickel, chromium and so on, with good binding force. The plating solution is stable, the formula is simple and the operation is convenient.
(1) It can be directly electroplated on the bottom layer of stainless steel, copper, nickel, chromium, etc., with good bonding force. (2) The plating solution is stable, the formula is simple, and the operation is convenient.
zinc-nickel alloy trivalent chromium black passivation agent produces a black decorative passivation layer with high corrosion resistance on the zinc-nickel alloy coating with a nickel content of 12-18% through a simple dipping process .
Zn-327 produces a black decorative passivation layer with high corrosion resistance on the zinc-nickel alloy coating with a nickel content of 12-18% through a simple dipping process. Suitable for rack plating and barrel plating, with high tolerance to zinc impurities.
use with sealants, 5% salt fog test white rust resistance greater than or equal to 72 hours. impurity excellent performance. Plating solution has long service life. Easy to operate and maintain. in barrel plating or automatic line passivation, collision or friction scratches will automatically repair.
Black passivator without hexavalent chromium,suitable for rack plating and barrel plating. Used together with a sealer,it can produce a dense black passivation layer on the acid zinc chloride coating. When used with a sealant,the anti-white rust time of 5% salt spray test is ≧72 hours. Excellent anti-impurity performance. The bath has a long service life. Easy to operate and maintain. In barrel plating or automatic wire passivation,the scratches caused by collision or friction will be automatically repaired.
Zn-323 can produce a blue passivation layer with excellent corrosion resistance on zinc-nickel alloy coatings with a nickel content of 12-15%. Through a simple dipping process, a uniform blue passivation layer can be produced with good bonding force. The sealing treatment can further improve the corrosion resistance and make the appearance of the coating change into the color of silver-stainless steel.
