Metal degreasing agent

Abstract

The invention discloses a metal degreasing agent, comprising the following raw materials in percentage by mass: 5-6 percent of diethanol amine caprate, 9-13 percent of sodium carbonate, 4-6 percent of fatty alcohol polyoxyethylene ether, 1.5-3 percent of polyoxyethylene polyoxypropylene monobutyl ether, 0.5-1 percent of benzotriazole and the balance of water. The metal degreasing agent has the characteristics of ultrastrong cleaning capability and defoaming property, less residue and good compatibility to refrigerating machine oil and refrigerant, and is suitable to the cleaning of parts of arefrigerant compressor. Meanwhile, the metal degreasing agent is nontoxic and harmless to a human body and has a good environment-protection effect.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a metal degreasing agent suitable for degreasing treatment in the production process of compressors. Background technique [0002] In the process of production and processing, the surface of the workpiece will inevitably be polluted. For this reason, it is necessary to use the corresponding cleaning agent for cleaning to ensure or improve the quality of the product. The purpose of cleaning is generally to remove grease, organic residues and pigment dirt, coatings and oxidized substances. [0003] Precision metal parts are the key parts of electronic machines and precision machinery products. Their processing and assembly are relatively precise and they are very sensitive to pollutants. The cleaning quality of precision metal parts directly affects the performance and reliability of electronic complete machines and precision mechanical products. As a precision mechanical product, the compress...

Problems solved by technology

[0011] At present, in the manufacturing industry of refrigerators and air-conditioning compressors, foreign degreasing agents monopolize the market of degreasing agents in the compressor manufacturing industry in my country, and the price of imported degreasing agents is expensive, which increases the manufacturing cost of compressors.

However, domestically produced degreasing agents generally have the following defects: pollutants: causing poor performance of the compressor, causing the compressor to be stuck, causing the compressor to be scrapped; poor anti-rust performance, easy to rust, causing the impurity content of the compressor to exceed the standard, causing The performance of the compressor is poor, causing the compressor to be scrapped; it is not easy to rinse and there is residue: damage to the refrigeration oil, resulting in poor lubrication, poor performance or overload of the compressor, damage to the refrigerant, causing the compressor to be scrapped, etc.
