AI Technical Summary

Problems solved by technology

Traditional degreasing agents are mostly high-foaming surfactant combinations. While obtaining a good decontamination effect, the surfactant components are often adsorbed on the surface of metal parts. Therefore, after working for a period of time, the emulsifier in the bath will gradually Loss of emulsifying properties, the emulsified oil gradually accumulates in the bath, but will be adsorbed to the surface of the metal parts that are subsequently put in, reducing the decontamination effect

Abstract

The invention discloses a metal degreasing agent. The metal degreasing agent is composed of, by weight, 10-20 parts of potassium silicate, 5-10 parts of trisodium phosphate, 1-5 parts of polyoxyethylene, 4-8 parts of isopropyl alcohol, 3-10 parts of mono-butyl ether, 5-15 parts of sodium hydroxide and 40-60 parts of deionized water. The metal degreasing agent is excellent in cleaning performance, good in defoaming performance, low in residue, nontoxic and harmless to human bodies, good in safety and suitable for cleaning all metal surfaces and parts.

Description

technical field [0001] The invention relates to the technical field of metal surface chemical treatment agents, in particular to a metal degreasing agent. Background technique [0002] Metal and its products are often contaminated with some stains and impurities on the surface during processing or after a period of use, such as iron chains used in automobiles. In order to ensure their safety and prolong their service life, they need to be cleaned , The first thing to clean is degreasing. Traditional degreasing agents are mostly high-foaming surfactant combinations. While obtaining good decontamination effect, the surfactant components are often adsorbed on the surface of metal parts. Therefore, after working for a period of time, the emulsifier in the bath will gradually Losing the emulsifying properties, the emulsified oil gradually accumulates in the bath, but it will be adsorbed to the surface of the metal parts that are subsequently put into it, reducing the decontamina...
