Water-based cleaning agents belong to the hard surface detergent series, which are suitable for environmental maintenance and cleaning of large-scale machinery and equipment. It is different from ordinary household cleaning agents and inorganic additives. In order to avoid metal corrosion during the cleaning process and a short time after cleaning, it is necessary to add a certain slow-release antiseptic; to increase the solubility of water-based cleaning agents in water and promote the decomposition effect of surface oil and dirt in water In the formula, a certain amount of flux needs to be added; in order to prevent excessive foam during the cleaning process from affecting the cleaning effect, some defoamers need to be added to extend the cleaning time; to prevent excessive foam during the cleaning process Affect the cleaning effect, prolong the cleaning time and need to add some defoamers; in order to prevent the redeposition of the dirt surface, also need to add anti-fouling agents, sometimes also add some organic solvents to make water-based oil-in-water emulsion liquid. The surface active agent that plays the role of washing can be used as a water-soluble emulsifier, and if necessary, some oil-soluble emulsifiers are added.
