Galvanic electrolytic galvanizing of parts and assemblies up to 1.5 m long is performed on a modern automated galvanic galvanizing line on hangers.
The line includes 4 alkaline galvanizing baths with dimensions of 1600x900x1200 mm.
The program introduced 3 modes of galvanizing 6 microns, 9 microns, 15 microns.
The capacity of the line with a coating thickness of 6 microns - 150 sq.m / 8 h.
On the line, an environmentally-friendly brilliant, cyanide-free zincing process developed by Columbia Chemical was introduced. A feature of the electrolyte used in this case is the selection of the components of Koltsink ACF-2 additives, in the aggregate of parameters superior to almost any such system.
The coating of this electrolyte is perfectly amenable to chromating and other types of treatment after galvanizing, they have excellent gloss and do not darken with time. Quality complies with international standards.
There is a possibility of applying high-quality zinc coatings on cast iron and high-carbon steels that are difficult to galvanize, cemented, heat-treated, etc.
Finishing zinc coating is carried out in the blue passivation of the company "Metal-Chemistry" (Austria-Germany). Passivation does not contain 6-valent chromium compounds, has high anticorrosive protection for up to 96 hours according to DIN EIN ISO 9227 NSS, creates a blue glossy passive film on galvanized zinc coatings.
