CORROSION PRIMER-TRANSFORMER

摘要

machine engineering. SUBSTANCE: invention relates to anticorrosion protection of carbon steel in large-sized units, members, tubes and other structures. The known rust primer-transformer including ortho-phosphoric acid and zinc oxide is mixed with basic bismuth gallate in the presence of chelating agent ethylene-diaminetetraacetic acid III-disodium salt. EFFECT: enhanced stability of anticorrosion protection of members made of carbon steel and technological effectiveness of large-sized members making. 2 tbl
