Cleaning And De-Greasing Of Metallic Materials By Chemical Methods
(AREA)
Abstract
FIELD: electrochemical degreasing of metal products. SUBSTANCE: method involves treating in orthophophoric acid solution with concentration of 0.1-2.8% by weight in anodic or pulsed polarization mode with the ratio of t:t= 2n:1, where tis cathodic polarization; tis anodic polarization; n = 0: 1.05 and current density is 0.1-10 A/dm. EFFECT: intensified process, elimination of corrosion of products and reduced consumption of rinse water. 2 tbl
