Oil removal agent for galvanized and aluminized steel plate

Abstract

A kind of degreaser for galvanized steel plate of the present invention is characterized in that, comprises the raw material of following parts by weight: Sodium carbonate: 0.1-5 part; Caustic soda: 0.01-1 part; Anionic surfactant: 10-1 part 20 parts; defoamer: 0.1-5 parts; polyaspartic acid: 1-5 parts; polyacrylic acid: 2-8 parts; complexing agent: 0.1-2 parts; water: 80-100 parts. The degreasing agent for galvanized steel sheets provided by the invention forms a dense protective layer on the surface of the material, overcomes the problem that the surface of galvanized materials is easily corroded, and effectively prevents the surface of the material from being damaged by primary battery corrosion or air oxidation. Mildew phenomenon, but also has a good degreasing effect, less pollution to the environment, no harm to the skin contact.

Description

technical field [0001] The invention relates to a degreasing agent for galvanized steel sheets. Background technique [0002] In metal surface processing, various kinds of grease will remain on the metal surface, and these residual oil stains will have an adverse effect on the subsequent processing quality. Therefore, a process of removing oil stains must be added. Traditional chemical degreasing usually uses acids and alkalis. While degreasing, it will also corrode the metal parts, which will also have a negative impact on the subsequent processing quality, and at the same time affect the health of the operator; the consumption of acid and lye is also large, which increases the processing cost; in addition, it will generate a large amount of The residues need to be discharged frequently, and the residual acid liquid not only seriously corrodes industrial pipelines, but also pollutes the soil and the environment. Contents of the invention [0003] In order to solve the ab...
