Problems solved by technology

[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 to carry out degreasing treatment. Most of the commonly used cleaning and degreasing agents are alkaline cleaning and degreasing agents (mainly composed of sodium hydroxide), and some are mixed with alkali (sodium hydroxide, sodium phosphate, etc.) and surfactants. These degreasing agents can be used for the degreasing treatment of most metals, but there is a protective film on the surface of some metal materials

Abstract

The invention relates to the technical field of fine chemical engineering, and specifically relates to a metal stain-removing and degreasing agent. The degreasing agent is composed of the following components in percentage by weight: 20 to 30% of sodium carbonate, 10 to 20% of sodium dodecyl benzene sulfonate, 10 to 20% of trisodium phosphate, 5 to 10% of isopropanol, 1 to 5% of alkylphenol polyoxyethylene, and the balance being deionized water. The provided metal stain-removing and degreasing agent has the advantages of little pollution and ideal effect.

Description

technical field [0001] The invention relates to the technical field of fine chemical industry, in particular to a metal stain and 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 to carry out degreasing treatment. Most of the commonly used cleaning and degreasing agents are alkaline cleaning and degreasing agents (mainly composed of sodium hydroxide), and some are mixed with alkali (sodium hydroxide, sodium phosphate, etc.) and surfactants. These degreasing agents can be used for the degreasing treatment of most metals, but there is a protective film on the surface of some metal materials such as stainless steel, copper, aluminum, etc., and the sodium hydroxide in the degreasing agent ...
