Problems solved by technology

[0002] Because metal profiles or equipment are stored in a humid environment for a long time in contact with air, the surface is easily oxidized to form rust stains, and it is easy to form scale when in contact with water. In addition, it is inevitable to be contaminated with oil such as cutting oil during metal processing, which will cause metal The corrosion and aging of profiles and equipment will reduce the service life. Therefore, it is necessary to clean the metal profiles
The traditional cleaning method is mainly strong acid cleaning, but strong acid is also very corrosive to metal profiles and equipment itself, while alkaline substances and surfactants are not effective in cleaning, and the cleaning cycle is short, which increases production costs

Abstract

The invention relates to an acid metal cleaner. The acid metal cleaner comprises the following components by weight percentage: 40% of hydrochloric acid, 5-10% of urotropin, 3-5% of sodium gluconate, 1-3% of oxalic acid, 2-3% of sodium dodecyl benzene sulfonate, 1-3% of AC1830 (N-Polyoxyethylated-N-octadecylamine), 1-3% of penetrant JFC, and the balance of water. According to the acid metal cleaner, rust stain, incrustation and oil stain of metal sections and equipment are effectively removed through the synergistic effect of acidic materials and surfactants, furthermore, the formula of the acid metal cleaner is simple, the acid metal cleaner can effectively lower the contamination degree, the cleaning period is long, and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of metal cleaning aids, and relates to chemical products for cleaning rust stains and oil stains on metal surfaces, in particular to an acidic metal cleaning agent. Background technique [0002] Because metal profiles or equipment are stored in a humid environment for a long time in contact with the air, the surface is easily oxidized to form rust stains, and it is easy to form scale when in contact with water. In addition, it is inevitable to be contaminated with oil such as cutting oil during the metal processing process, which will cause metal damage. The corrosion and aging of profiles and equipment will reduce the service life. Therefore, it is necessary to clean the metal profiles. The traditional cleaning method is mainly strong acid cleaning, but strong acid is also very corrosive to metal profiles and equipment itself, while alkaline substances and surfactants are not effective in cleaning, and the ...
