According to the principle of the scouring agent, as a high-efficiency scouring agent, it must have the conditions of rapid penetration, strong emulsification and dispersion, high cleaning power, low foaming, high temperature resistance, strong alkali, hard water, easy biodegradation, safety and non-toxicity. Therefore, a single surfactant cannot meet the requirements, and is usually a compound of multiple components.
When selecting the components of a high-efficiency scouring agent, 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, it is necessary to analyze the compatibility of two or more surfactants or other auxiliaries, and the compatibility between the components after a certain ratio of compounding and the possible synergy and synergistic effects.
Comprehensive composition of various scouring agent products, the main components are a mixture of anionic and non-ionic surfactants, in addition to the addition of defoamers, electrolytes, chelating dispersants, cosolvents, fiber protection agents, etc. . 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.
