Abstract

The invention discloses a low-foam surface activist for cleaning, which is characterized by the following: two or three random proportions of span type, tween type, OP type and AEO type are mixed together to produce activating material; the span typed raw material contains span20, span40, span60 and span80;the tween typed raw material contains tween20, tween40, tween60 and tween80;the OP typed raw material contains OP-4, OP-9 and OP-10; The AEO typed raw material contains AEO-7, AEO-9, AEO-10, AEO-15 and AEO-20. The invention is easy to dissolve in the water, which cleans blood and oil stain by over 90 percent.

Description

technical field [0001] The invention relates to a low-foaming surfactant for cleaning, which is used as a cleaning aid for cleaning liquid used in automatic cleaning equipment. Background technique [0002] At present, the cleaning of medical equipment has entered the automatic cleaning process. A necessary condition for automatic cleaning is that there must be less foam and it can disappear in time. At the same time, it has no corrosive effect on the equipment and the items to be cleaned, and there are few residues, which are not harmful to the human body. The low-foaming surfactants currently used for non-medical equipment cleaning are all added with polyphosphorus compounds or silicone defoamers. These substances are not only harmful to the human body and the environment, but also damage our equipment and instruments. It is beneficial to be used as an auxiliary agent for medical instrument cleaning. Contents of the invention [0003] The object of the present inventio...
