What else are detergents of that type used for?

Cleaning agents are a large category with a wide variety, including two categories: inorganic cleaning and organic cleaning. The difference between organic cleaning agents and inorganic cleaning agents Simply put, organic cleaning agents are cleaning agents made of carbon-containing compounds, and inorganic cleaning agents are cleaning agents made of carbon-free compounds, so they are inorganic. There are also many classification methods of cleaning agents, which vary from country to country. Our country is usually divided into three categories: aqueous, semi-aqueous, and non-aqueous cleaning agents. Cleaning agent (water system) It is made up of surfactants and various auxiliaries and auxiliary agents, which can reduce the surface tension of the aqueous solution and improve the decontamination effect when washing the dirt on the surface of the object. Water is an important cleaning agent and has a role and status that cannot be replaced by any other cleaning agent. Ordinary water is easily obtained from nature, and water has strong dissolving and dispersing power. However, the surface tension of water is large, and a surfactant needs to be added in use to reduce the surface tension and increase the surface wettability. In general industrial cleaning, the combination of acid, alkali and water is more common, and some metals need to be washed with rust inhibitor; in precision and ultra-precision industrial cleaning. Cleaning agent (semi-aqueous system) is a new cleaning agent product which is a new type of cleaning agent product synthesized by fine-grained weak alkaline adsorption of various additives. It uses natural interface active abrasive particles as raw material, and is combined with a variety of active agents and bactericides, polishing agents, and imported penetrants. It is formulated with high-tech environmental protection technology such as agent and unique brightening factor. It is a multi-functional and efficient comprehensive environmental protection cleaning and care product. It is a modern new decontamination product with unique decontamination effect, wide application and no side effects on human skin. Semi-aqueous cleaning agents are also called quasi-aqueous cleaning agents, which are composed of high-boiling point solvents and active agents such as alcohols. Ethylene glycol esters, organic hydrocarbons, N-methylpyrrolidone, etc. Usually contains 5% to 20% moisture, generally not easy to burn. But when heating and cleaning. Improper control of water content. Combustion may occur. There are some differences between semi-aqueous cleaning and solvent cleaning. Its cleaning principle is to peel off. rather than dissolve. In order to prevent the peeled oil from reattaching to the object to be cleaned, the cleaning liquid should be continuously circulated, and an oil-water separator should be added. Semi-washing usually has a good cleaning effect, but the operating cost is high. The waste liquid cannot be recycled and reused, and the COD content is high, so waste water treatment is required.
