Abstract

The invention discloses a cleaning agent for heavy oil dirt. The cleaning agent for the heavy oil dirt is characterized by comprising the following components in percentage by weight: 8 to 15 percent of surfactant, 2 to 8 percent of cosolvent, 4 to 10 percent of corrosion inhibitor, 3 to 12 percent of wash aid and the balance of deionized water. The cleaning agent for the heavy oil dirt has the advantages of excellent cleaning capability, low using temperature, wide application range, environmental friendliness and no pollution, does not contain ozone depleting substances (ODS), phosphate and nitrite, has excellent cleaning effect on oil dirt generated by machining of steel, aluminum and copper, and is a high-efficiency, environment-friendly and multi-purpose cleaning agent product for the heavy oil dirt.

Description

technical field [0001] The invention relates to the field of industrial cleaning agents, in particular to a water-based heavy oil dirt cleaning agent in metal processing. Background technique [0002] As we all know, cleaning ability is the fundamental performance of cleaning agents, and the international environmental requirements for water-based cleaning agents are becoming more and more stringent. However, most of the water-based cleaning agents at home and abroad are low in cleaning efficiency or not environmentally friendly. To improve the cleaning ability, add solvent components or increase the use temperature. With the development of science and technology, more and more metals are processed, and the amount of cleaning agent required during processing is also increasing. Most of the existing cleaning agents are divided into steel, aluminum, and copper metal cleaning agents for different metal materials. When the processing manufacturer changes the processing batch, t...
