During the maintenance and repair of machining and mechanical equipment, automobiles, etc., diesel, kerosene, and other cleaning fluids are mostly used to clean parts, which not only wastes resources but also easily creates safety hazards; In recent years, a new type of metal cleaning agent has gradually been widely used. It can replace diesel and kerosene to clean equipment parts, and is cheap, safe and environmentally friendly. It is suitable for mechanical operations and can clean metal surfaces without leaving any residue. This is metal cleaning agent.

For metal cleaning, one is to remove oil and the other is to remove rust. The metal cleaning agent for cleaning oil stains consists of surfactants and additives. Surfactants are generally aliphatic derivatives or aromatic derivatives of all aliphatic hydrocarbons, which have strong wetting, solubilizing, and emulsifying abilities against dirt. Rust and corrosion inhibitors are essential components of metal cleaning agents, which are used to clean metal surfaces without corrosion or damage. The cleaning button makes the metal surface clean and bright, and has a certain corrosion and rust inhibiting effect. A targeted cleaning agent suitable for various metal materials, which will not corrode the surface of the material. Metal cleaning agents can be roughly divided into five categories: acidic chemical cleaning agents, alkaline chemical cleaning agents, water-based cleaning agents, semi water-based cleaning agents, and solvent based metal cleaning agents.

1. Acid cleaning agent: Using acidic inorganic reagents to chemically react with oil stains on metal surfaces, separating the oil stains from the metal surface. It is generally only used for cleaning black metals. Acid reagents are corrosive and cause significant harm to the environment and human body.

2. Alkaline cleaning agent: It uses alkaline reagents to disperse oil stains and is suitable for cleaning ferrous metals. However, the cleaning effect is not good and requires a certain temperature, which poses a risk of dissolution to human skin and clothing.

3. Water-based metal cleaning agent: It cleans oil stains through the emulsification, penetration, dispersion, and redeposition capabilities of surfactants, additives, and other reagents. Its main feature is that it has a good cleaning effect on mineral oil, has a wide range of applications, has no impact on metal surfaces, and is thoroughly cleaned without dead spots. Can be used for ferrous and non-ferrous metals.

4. Semi aqueous metal cleaning agent: By using water and solvent as the cleaning medium and utilizing the emulsification effect of active substances, a water in oil type cleaning agent is formulated. Its application is limited and its market promotion is weak.

5. Solvent based metal cleaning agent: Organic solvent has good cleaning effect, but cannot clean water-based dirt.

Under the influence of imperfect traditional thinking concepts and cleaning techniques in the industry development, some enterprises and individuals still rely solely on mechanical high-pressure water washing, chemical acid washing, and other methods for scaling and cleaning of metal equipment. The neglect of equipment fouling and the selection of incorrect cleaning methods have caused damage or even scrapping of metal equipment, affecting production. Metal degreasing cleaning agent is a type of metal cleaning agent, and its market size is gradually increasing in China.
