1. The color is specially white and similar with real white chromium, the plating solution is stable, and bath never be muddy under the normal condition.
2. Wide application range and good combining ability.
3. This process and additive have cross the detection by SGS, and meet the RoHS2002/95/ES regulation. The deposits is specially stable , high hardness and strong wear resistance.
1.Make up method：
substitute chromium salts dissolved in water, A agent measurement, then adjust the pH to 11, agent B measurement, and then transferred to PH bath, mixing evenly, can produce.
Plating solution consumption and addition:
a.1000AH consumption addition:
(717)-A 2~3kg, (717)B ,1.5-2.5kg
substitute chromium salts 100~200g
b. add raw material as the proportion, A: B : substitute chromium =1: 0.8-0.9 :0.3
2. Operation condition:
Rack cathode current density 0.8 A/dm2,
barrel cathode current density 80 A/ dm2
rack time45s，time7min，PH 10.5 baume27Be0，temperature45 ℃,agitate cathode swing，continuous filter
3. Product catalog：substitute chromium A, substitute chromium B, substitute chromium salts.
