Brightening rust remover for explosion-proof motor

Abstract

The invention discloses a brightening rust remover for an explosion-proof motor. The brightening rust remover comprises the following substances in percentage by weight: 30%-50% of hydrochloric acid, 1%-5% of hexamethylenetetramine, 2%-8% of sodium dodecyl sulfate, 5%-10% of peregal 0S-15, 1%-2% of a stabilizer and the balance of water.

Description

technical field [0001] The invention relates to a brightening and derusting agent for an explosion-proof motor. Background technique [0002] Iron and steel products are easily corroded in the atmospheric environment. The amount of steel lost due to corrosion every year in the world is very large. In order to solve or reduce the corrosion of steel products, various anti-corrosion measures are often adopted. One anti-corrosion measure is to cover the steel surface with a protective layer To isolate the direct contact of air and steel. Iron and steel products must remove the rust on the surface before covering the protective layer. The current rust removal methods mainly include mechanical methods and chemical methods. Mechanical methods such as manual shoveling, grinding, sandblasting, etc. have the disadvantages of high labor intensity, low efficiency, serious dust pollution, and are limited by the shape of components, such as edges, corners, concave corners, and rust on th...

AI Technical Summary

Problems solved by technology

Mechanical methods such as manual shoveling, grinding, sandblasting, etc. have the disadvantages of high labor intensity, low efficiency, serious dust pollution, and are limited by the shape of components, such as edges, corners, concave corners, and rust on the inner diameter of thin tubes are difficult to clean. Utilize the chemical method of descaling agent to be the most widely used method in industry at present, the product kind of relevant iron and steel descaling agent at home and abroad is of a great variety at present, and iron and steel descaling agent is usually various acid liquids, and with sulfuric acid and hydrochloric acid composition Mainly, the existing problem is that sulfuric acid has poor dissolving ability to scale, and it needs to be carried out at high temperature, which is prone to hydrogen embrittlement, and the surface state of steel after pickling is not ideal.
