Description

Изобретение относится к прикладной химии, в частности к смесевым составам и композициям, предназначенным для защиты черных металлов и сплавов от атмосферной коррозии.The invention relates to applied chemistry, in particular to mixed compositions and compositions intended to protect ferrous metals and alloys from atmospheric corrosion.

Цель изобретения - повышение степени защиты низколегированных сталей от атмосферной коррозии и повышение эффективности преобразования обрабатываемой поверхности.The purpose of the invention is to increase the degree of protection of low alloy steels against atmospheric corrosion and to increase the conversion efficiency of the machined surface.

Состав для защиты металлов от коррозии содержит ортофосфорную кислоту, ацетон, воду, изопропиловый спирт, бутилацетат и о-крезол.The composition for protecting metals from corrosion contains phosphoric acid, acetone, water, isopropyl alcohol, butyl acetate and o-cresol.

Изобретение позволяет при нанесении состава на обрабатываемую поверхность преобразователь имеющиеся на ней продукты коррозии в устойчивую защитную фосфатную пленку.The invention allows, when applying the composition to the treated surface of the converter, the corrosion products present on it into a stable protective phosphate film.

Обработка деталей и узлов осуществляется как погружением их в емкость с приготовленным составом, так и с помощью кисти, ветоши и других подручных средств, при этом сушка обработанной поверхности проводится при температуре окружающей среды.Processing of parts and assemblies is carried out both by immersing them in a container with a prepared composition, and using a brush, rags and other improvised means, while drying the treated surface is carried out at ambient temperature.
