Abstract

The invention relates to the technical field of daily chemical cleaning, and particularly discloses a detergent for machine-washed tableware and a preparation method of the detergent. The detergent for machine-washed tableware is prepared from the following raw materials in percentage by weight: 15-25% of strong alkali liquor, 0.1-0.4% of an anionic dispersant and 1.5-3% of sodium citrate, with the balance being water. The preparation method comprises the following steps: adding the water into a stirring container at room temperature and normal pressure, starting stirring, adding the strong alkali liquor, and carrying out stirring; and then sequentially adding the anionic dispersant and the sodium citrate, and carrying out uniform stirring. According to the preparation method, the water isadded into the stirring container at room temperature and normal pressure, then stirring is started, the strong alkali liquor is added and uniformly mixed with the water under stirring, then the anionic dispersant is added and stirred, the sodium citrate is added, and uniform mixing under stirring is conducted. The detergent for the machine-washed tableware can be used for machine washing of tableware, and has the advantages of strong cleaning and decontamination capability, reduction of re-scaling precipitation, safety, no toxicity and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of daily chemical cleaning, more specifically, it relates to a detergent for machine tableware washing and a preparation method thereof. Background technique [0002] Dishwasher cleaning removes the dirt on the tableware mainly by virtue of the three-dimensional spraying effect of the strong water flow in the three-dimensional space, the heat energy effect of the heated water, and the degreasing and decontaminating effect of the cleaning agent. After being pressurized by the booster pump, the water flow sprayed from the nozzle into the dishwasher rotates in the machine, and there is no dead angle in the machine that cannot be cleaned. The strong water flow energy impact generated by the spray can effectively remove the tableware. Adhesive dirt. [0003] Studies have shown that the cleaning effect of water flow mechanical energy accounts for 58% of the total cleaning effect in the decontamination process, wh...
