ANTICORROSIVE PIGMENT |
摘要 |
technology of preparing anticorrosive pigments in vanishpaint industry. SUBSTANCE: essence of the invention lies in anticorrosive pigment which is calcium phosphate-chromate at molar ratio of phosphate and chromate ions from 1:1 to 4:1. Anticorrosive pigment is intended for reducing toxicity due to decreasing solubility thereof in water by partial substitution of chromate ion for phosphate ion without deteriorating anticorrosion properties. All the resulting pigments are capable of lowering corrosion current and shifting potential of steel to region of active corrosion inhibition. EFFECT: improved properties of the anticorrosive pigment. 4 ex, 2 tbl
