2. Zincate zinc plating
Zincate zinc plating process is evolved from cyanide zinc plating. At present, there are two main factions in China, namely:
(1) DPE series of Wuhan Institute of material protection
(2) "De" series of radio and television stations
Both of them belong to zincate zinc plating with alkaline additives; pH value is 12.5 ~ 13. The results show that the lattice structure of the coating is columnar with good corrosion resistance and is suitable for color zinc plating.
Typical formula: NaOH -- 110 ~ 120g / L; ZnO -- 11 ~ 12g / L; 94 -- 5 ~ 7g / L. 94 is the product code, which is the combination of DPE - Ⅱ and ethanolamine.
Note: after the product is out of the tank, the product is washed with water, polished with nitric acid and hydrochloric acid, washed with water, passivated with passivation, washed with water, washed with water, dried, and aged at 80 ~ 90oC in the oven.
