Abstract

The invention provides a cleaning agent for an automatic tableware washing machine, which consists of surfactants: one or two kinds of polyoxyethylene sorbitan monooleate or ethylenediamine PO-EO block copolymer, oleic acid, hydrogen Potassium oxide, trisodium phosphate, distilled water synthesis. The proportion of components is as follows: surfactant 2-35, oleic acid 2-10, potassium hydroxide 0.5-2.5, trisodium phosphate 1.5-7.5, the rest is distilled water, the cleaning agent is low alkali, no corrosion to the cleaning machine, It is safe to the environment and human body; especially without foam, even under stirring, there is very little foam, and the cleaning effect is very good.

Description

technical field [0001] The invention relates to a cleaning agent for an automatic tableware washing machine. More specifically, it refers to cleaning supplies for automatic dishwashing machines. Background technique [0002] The use of automatic tableware washing machines has a history of more than 30 years, but the machine-washing tableware cleaning agents in my country are mainly used for hotels, restaurants and various catering services. The main requirements for the cleaning agent used are: it can effectively remove the dirt (such as food residues, grease, etc.) Form scum; good fluidity during long-term storage; no corrosion to the inner cavity and parts of the dishwasher, and should not leave residue or darken the surface; the cleaning agent should also have certain antibacterial properties. Since most automatic tableware washing machines are cleaned by high-pressure jet cleaning, the cleaning agent should not produce foam, and there should be little foam under stirri...
