The benefits of galvanizing:
- Galvanizing is more durable than painting parts (the paint does not resist the blows, while galvanizing becomes one with the part, resisting deformities).
- Galvanizing is up to 70% cheaper than painting (and it is usually faster).
- Galvanizing makes parts remain fireproof (while paint usually catches fire).
- Zinc is not toxic for the environment (paints are, and reducing painting operations reduces the amount of harmful substances emitted in the air).
- Alkaline galvanizing is more resistent in time than weak acid galvanizing.
Treatments start by degreasing chemically the surface to eliminate both fats, salts and fine dust from the thermal treatments, the surface of the part.
Pickling is the elimination of corrosion products from metal surfaces.
Electrochemical degreasing complements chemical degreasing to remove residual film body fat and to get rid of all the impurities on the surface.
Removes the thin film formed during transfer through an acid wash.
THE ACTUAL ELECTROLYTIC DEPOSITION
On the surface of parts is deposited electrolytically a thin and uniform layer of zinc.
Passivation has the role to form a film of compounds that prevent the reactions that can occur at the surface of zinc when in contact with the environment, and to confer corrosion resistance and give the part a pleasant look.
After each stage of the technological process, a washing step follows to remove the layer of solution that adheres to surfaces.
Drying takes place in a room-type furnace.
