Metal cleaning agent is a chemical preparation used to clean the metal surface. It can remove oxidation layers, oils, stains and other impurities, and restore the metal surface to restore smoothness and brightness. The ingredients of metal cleaning agents may be different according to the specific application and cleaning requirements. The following are some common metal cleaning agents:
Acids: acids are one of the common ingredients in metal cleaning agents, such as sulfuric acid, hydrochloric acid, and phosphate. Acids can effectively dissolve the oxidation layer and dirt on the metal surface, and remove rust and stains on the metal surface.
Alkali: Alkaline ingredients such as sodium hydroxide and potassium hydroxide are often used in metal cleaning agents. Alkaline substances can help clean the oil and organic stains on the surface of the metal surface, and at the same time can neutralize acidic substances to avoid corrosion of metal.
Surface active agent: Metal cleaning agents usually contain surfactants, such as anionospeitter surfactants, cationic surfactants, and non -ion surfactants. Surface active agents have a good pollution and decentralized effect, which can make dirt more easily washed away by water.
Correspondence: Metal cleaning agents may be added with a corrosion agent to reduce the corrosion effect on metal. A corrosion agent can form a protective film to prevent acid or other chemicals from further eroding the metal surface.
Salvas: Some metal cleaning agents may contain dirt deodorants, such as chelating agents, complexing agents, etc. These compounds can form complexity with metal ions, and unlock the metal ions from the metal surface to achieve the effect of removing the metal scale layer.
It should be noted that the selection of metal cleaning agents should be carried out according to the metal type, stain type and cleaning requirements to be cleaned, and use strictly in accordance with the instructions and operating regulations to avoid damage to the metal and the environment.
