Abstract

The present invention relates to a substance which removes rustiness on the surface of steel and iron, in particular to brightening rust remover, which solves the problem that the steel and the iron have gloomy surfaces after the rust removing in the prior art. The brightening rust remover is composed of materials in the following weight ratio: chlorhydric acid is 30-50 percent, hexamethylene tetramine is 1-5 percent, sodium lauryl sulphate is 2-8 percent, peregal OS-15 is 5-10 percent, and the residual is water. The present invention has the characteristics that rustiness can be removed quickly, the steel and the iron are brighter than the original state after the rustiness is removed, no over corrosion and hydrogen brittleness phenomenon exist, no pollution exists, and the cost is low, etc. Since the difference of the degrees of corrosion, the rustiness removing time is generally within 1-5 minutes.

Description

technical field [0001] The invention relates to a material for removing rust on steel surfaces, in particular to a brightening and rust removing agent. 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, ...
