METHOD OF MANUFACTURING OF BATH FOR GALVANIC PRODUCTION Russian patent published in 2015 - IPC C25D17/02 

FIELD: machine building.

SUBSTANCE: invention can be used during manufacturing of the bath for galvanic production with work electrolytes having neutral, alkali and acid environment working at temperature from -30 to +30°C, and washing baths of galvanic production, tanks for corrosive liquids and wastes drainage, storage and recycling. The method includes formation of the internal protective coating on the metal housing. The protective coating is made by PVC tape with adhesive layer installation on the internal bath surface, the adhesive layer is composition out of PVC resin and plastifier. At that initially tape is installed on the welds of the bath casing, on them preliminary glue BF-4 is applied with addition of the protector filler in amount of 25-30 parts by weight per 100 parts by weight of the glue, at that ultrafine zinc is used as the protector filler, the PVC tape is applied with adhesive layer over the entire bath surface overlapping joints of the previous layers by the successive tape layers.

EFFECT: assurance of effective bath corrosion protection, easy manufacturing and repair of bath with any dimensions upon presence of different holes for corrosion chemicals inlet-outlet.
