According to the principle of action of the scouring agent, as an efficient scouring agent, it must have the conditions of rapid penetration, strong emulsification and dispersion, high cleaning power, low foaming, high temperature resistance, concentrated alkali, hard water, easy biodegradation, safety and non-toxicity. Therefore, a single surfactant can not meet the requirements, usually a compound of multiple components.
When selecting high-efficiency scouring agent components, we must first analyze the wetting, penetrating, emulsifying, dispersing, and cleaning properties of various single surfactants, as well as chemical stability, safety, and biodegradability from the structure and performance. Etc .; secondly, to analyze the compatibility of the two or more surfactants or other auxiliary agents, the compatibility between the components after a certain proportion, and the possibility of synergy and synergy.
Combining the composition of various types of scouring agent products, the main components are a mixture of anionic and nonionic surfactants. In addition, defoamers, electrolytes, chelating and dispersing agents, co-solvents, fiber protection agents, etc. must also be added . The reason for using the mixed components of anionic and nonionic surfactants is that the combination of these two surfactants has a very obvious synergistic effect, which can improve the wetting, penetrating, emulsifying and cleaning capabilities of the scouring agent. Make up for the shortcomings of non-ionic and anionic surfactants.
