1, soluble emulsifying cleaning agent
a soluble emulsifier is usually composed of emulsifier, soil, solvent, builder, corrosion inhibitor, and a small amount of water. The function of water is to dissolve the emulsifier. This cleaning agent dissolves the dirt on the surface of China fasteners, while also leaving a layer of anti-rust filmed on the surface of China fasteners. An emulsified cleaning agent is a concentrated pure oil product, which becomes a white milky liquid after being diluted in water. The emulsifier and detergent can hold the grease particles and dissolve them into the cleaning agent containing solvent and oil.
2, alkaline cleaning agent
The alkaline cleaning agent is a mixture of builders and alkaline earth metal salts of surfactants. It is the most widely used cleaning agent. The pH value of the cleaning agent is required to be around 7. The cleaning ingredients of this type of cleaning agent are hydroxide, silicate, carbonate, phosphate, borate, and organic chelate. Each of the above salts and surfactants is mainly to ensure the cleaning effect, followed by the economy.
Decontamination cleaning agent mainly contains a solvent, surfactant, and water. Different from an emulsified cleaning agent, it is a pure solution, not an emulsion. It is mainly used for maintenance cleaning of equipment and China fasteners outer packaging.
4, synthetic cleaning agent
A synthetic cleaning agent is also an alkaline cleaning agent, which is different from the standard alkaline cleaning agent in chemical composition. The standard alkaline cleaning agent is essentially inorganic, while the synthetic agent is an organic agent containing amine-based substances. Standard alkaline cleaners are used to remove alkaline residues in single-stage cleaning, and they are also good rust inhibitors. Synthetic cleaning agents are used for medium-level cleanings, such as quenching oil or quenching polymer solution for cleaning the surface of China fasteners.
5, acid cleaning agent
"Usually there are organic acids such as sulfuric acid, hydrochloric acid, nitric acid, citric acid, and acetic acid. For high-strength China fasteners dephosphorization film before heat treatment, currently, the first three cleaning processes are mainly used, but hydrogen corrosion should be prevented. The acidic agent should contain basic acid and corrosion inhibitor to prevent corrosion of the surface of metal China fasteners, as well as a surfactant to improve the cleaning ability. But for cleaning the general dirt on metal China fasteners, acidic cleaning agents are generally not used, and alkaline cleaning agents are usually used. Acid cleaning is very effective for special attachments such as oxide scale. The most famous process is acid leaching. In addition to rolling, welding, and heat treatment of oxide scale, surface oxides, rust and corrosion products that affect the quality of electroplating or oil seals, and water-stained deposits can all be removed with acid.
