Abstract

The invention discloses a rust removal cleaning agent, which is prepared by uniformly mixing the following components in parts by mass: 10 to 15 parts of EDTA (ethylene diamine tetraacetic acid), 4 to 10 parts of a surfactant, 1 to 3 parts of bentonite and 3 to 4 parts of a corrosion inhibitor, wherein the surfactant is one of polyoxyethylene stearate and diethylene glycol fatty acid ester; the corrosion inhibitor is one of benzotriazole, petroleum sulfonate, alpha-hydroxybenzotriazole, hexamethylenetetramine, tallow amine and 8-hydroxyquinoline.

Description

technical field [0001] The invention relates to a rust remover, in particular to a rust remover for removing rust on steel surfaces. Background technique [0002] With the development of the steel industry and steel manufacturing industry, the problem of steel corrosion has become increasingly prominent. The weight of metal materials and equipment scrapped due to corrosion in the world is about 20% to 30% of the annual output of metal, as high as 1×108t or more. Before taking various anti-corrosion measures on metal products, rust removal is a necessary process step. [0003] There are mechanical, chemical and electrochemical methods for derusting. In China, the traditional soaking and pickling process is generally used, which has a good light effect and simple waste liquid treatment, achieving the purpose of taking into account the quality of derusting and environmental protection. But this type of immersion method must have a washing tank with a considerable volume to sto...
