Domestic plating filtrate classification, can be divided into four categories
The electrolytic plate electrolytic plate, galvanized sheet, knowledge, nicknames galvanized sheet, namely the use of electrolysis, in parts dial form a uniform, closely combined with a good layer of metal or alloy siltation process. Compared with other hardware, zinc is relatively expensive and prone tin plate sheet to plating a metal, is a low-value corrosion-resistant plating layer. Is widely used to protect steel parts, especially to prevent the atmosphere from corrosion, and for ornaments. Plating the plating receiving slot (or rack plating), barrel plating (for small parts), artificial plated and continue plating (for wire, strip).
Electrolytic plate by the CAPL unit annealing cold even compactor group rolling again, into the electric galvanizing line, plating across the dial cleaning after plating, different evidence useful, can phosphating, passivation, oiling and fingerprint resistant alloying after treatment obtained goods, machine performance with reference to the corresponding substrate.
Domestic plating filtrate classification, can be divided into four categories:
1. Cyanide zinc:
(CN) is a highly toxic, because the ranger on the use of cyanide electro-galvanized proposed strict restrictions continue to promote reducing cyanide and to replace tin plate cyanide electro-galvanized plated solid system development requires the use of low cyanide plating solution (micro-cyanide). Using this process plating, the quality of the goods, especially color-plated by the pigment after passivation remains.
2. Zincate:
This process is evolved by cyanide zinc. Currently the formation of the two major parties, farewell: a) Wuhan material security are "DPE" series; b) radio and television are the "DE" series. Are attributed to the the acidic additives zincate; PH value of 12.5 to 13. The use of this process, the lattice tinplate coils structure of the coating is columnar, good corrosion resistance, suitable for orthochromatic galvanized. Note: the goods out of the groove → washing → light (nitrate + phosphate) → washing → passivation → washing → washing → hot dry → drying → aging treatment (oven body 80 to 90 ℃).
3. Sulfide galvanized:
This process is used in electroplating cause the observed proportion of up to 40%. (Blue) decent zinc chromium (with chrome passivated comparable), especially in the plus water soluble enamels, plating layman is difficult recognizable is galvanized or chrome-plated. This process is suitable for the white the passivation (blue and white, silver).
4. Sulfate zinc:
This process is suitabl
