Problems solved by technology

[0003] At present, the metal cleaning agents sold on the market are mainly used to clean metal parts. They are cheap, safe to use, and suitable for mechanized operations. There are many metal cleaning agents on the market, but most of them have raw materials that are not environmentally friendly, and there are residues after cleaning. It is corrosive to metal and has many foams, which are not easy to remove.
Among them, the metal corrosion caused by cleaning will lead to leakage and shutdown of metal equipment if it is serious, which will bring huge losses to consumers.

Abstract

The invention provides a metal cleaner. The metal cleaner comprises the following components in parts by weight: 0.5-1 part of ultra-low interfacial tension surfactant, 0.5-1 part of acid cleaner, 0.1-0.5 part of acid inhibitor, 0.01-0.05 part of bactericide, 0.01-0.05 part of pH conditioner, 3-10 parts of organic solvent, and 80-150 parts of water. The metal cleaner can be used for cleaning a metal part. The metal cleaner is good in cleaning effect, free of residue, free of corrosion on metal and stable in property.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a cleaning agent for metal surfaces, which has the functions of decontamination, rust removal, anticorrosion and stable properties. Background technique [0002] At present, diesel, kerosene or gasoline are mostly used to clean metal parts during mechanical processing and automobile maintenance, which not only wastes energy, but also brings danger due to the use of flammable substances. In recent years, people have attracted more and more attention to the industry, and new metal cleaning agents have gradually been developed and widely used. [0003] At present, the metal cleaning agents sold on the market are mainly used to clean metal parts. They are cheap, safe to use, and suitable for mechanized operations. There are many metal cleaning agents on the market, but most of them have raw materials that are not environmentally friendly, and there are residues after cleaning. It is corrosive to ...
