CABINET HOUSING
Special research has been conducted on the
anti-corrosion treatment of the cabinet to ensure
resistance to the most severe environmental conditions.
The entire course of treatment is as follows:
1. Removal of
grease from the metal parts,
2. Rinsing in
water to eliminate all alkaline residue,
3. Zinc
phosphatization: thickness 5 µm,
4. Passivation,
ensuring an increase in the corrosive resistance of the
coat of phosphate obtained,
5. Elimination of
residual salts (ions), through rinsing with de-mineralised
water,
6. Final
treatment by cataphoresis, thickness: maximum of 22 µm.
(Cathodic process). |
