Zhanjiang and chromium plating factory - Zhanjiang best selling plating brightener - the best agent on behalf of the chrome light

Hui group 13686661868 http://www.dghaolun.com HL- and chromium plating and chromium plating process manufacturers Zhanjiang - Zhanjiang best selling plating brightener - the best agent on behalf of chromium and chromium light is a completely new type of chromium VI environmental plating process, low energy consumption, corrosion resistance coating color and can be comparable with chromium plating covering power far better than chrome, two-component cylinder open and easy maintenance, small parts for conventional barrel plating production and large parts hanging plating production, significant economic benefits. First, the operating conditions of Zhanjiang and chromium and chromium A (ml / l) 300 to 400 and chromium B (ml / l) a current density of 100 to 200 60 ~ 100A / barrel (barrel) 0.5 ~ 2.0 A / dm2 (rack) mixing method 4-8 rev / min (barrel) 25 to 30 beats / min (rack) pH value (available sulfuric acid or sodium hydroxide to adjust) 10.0 to 11.0 temperature 20 ~ 50 ℃ anode 1 Cr 18 Ni 9 Ti stainless steel Note : Hanging chrome plated Times A, B take maximum, take the lower limit Barrel; blue color requirements to take maximum age chromium A, B take lower; require white era take lower chromium A, B to take maximum. Second, Zhanjiang and chromium bath preparation 1. 20% of the first predetermined volume of pure water was added plating tank; 2. The desired amount of generation of chromium A, stir; 3. Stirring slowly added and chromium B, and add water to the required volume; 4. Loop filter, aging after 4-8hr, appropriate heating trial plating.
