Problems solved by technology

At present, the cleaning liquid commonly used for cleaning aluminum sundries mainly includes two types: one is alkaline cleaning liquid, after the cleaning liquid cleans aluminum, the aluminum is easy to change color, and white spots appear on the surface of cast aluminum parts; It is an acidic cleaning solution. After the cleaning solution washes aluminum, white spots will appear, and mildew spots will appear in humid climates.
From the above description, it can be seen that white spots will appear after the existing cleaning solution treats the surface of the aluminum material.

Abstract

The invention relates to a cleaning agent specially for an aluminum product. The weight percentage for the components is as follows: inorganic acid 15 to 45 percent, organic acid 3 to 8 percent, surface active agent 5 to 12 percent, penetrating agent 8 to 15 percent, organic solvent 10 to 20 percent and water 25 to 35 percent. The invention has simple yet scientific mechanism of action, convenient use and notable effect. The invention can clean the surface of the aluminum product rapidly in a soaking mode at a normal temperature, can effectively eliminate the white patches, the mildew stains, oil stains and zinc stearate on the surface of the aluminum product and can permanently eliminate the white patches and the mildew stains on the surface of the aluminum product. In addition, the invention has a wide source of raw material, which is easy to be obtained and has a low cost. The invention is fit for a mass industrial production.

Description

technical field [0001] The invention relates to the field of chemical cleaning agents, in particular to a special cleaning agent for aluminum materials. Background technique [0002] Due to penetration, environment, and processing, aluminum is prone to produce white spots, mildew, oil, zinc stearate and other pollutants. When processing this type of aluminum, the surface of the aluminum must be thoroughly cleaned to remove the aluminum. White spots, mold spots and other sundries on the surface of the wood. At present, the cleaning liquid commonly used for cleaning aluminum sundries mainly includes two types: one is alkaline cleaning liquid, after the cleaning liquid cleans aluminum, the aluminum is easy to change color, and white spots appear on the surface of cast aluminum parts; It is an acidic cleaning solution. After the cleaning solution washes the aluminum, white spots will appear, and mildew spots will appear in humid climates. It can be seen from the above descript...
