双子表面活性剂在皮革工业中的应用

Application of Gemini Surfactants in leather industry

常用双子偶合表面化学活性剂也可简称为双偶合表面化学活性剂,双偶合表面化学活性剂或简称偶合双子表面化学活性剂。它们也都是新型的人体表面氧化活性剂。表面化学活性剂团的分子结构是通过不断结合接近亲水基区的团或结合接近亲水基区的团而直接形成的。考虑到每个亲水基离子团的化学性质,双子体的表面化学活性剂一般可以细分为四种离子类型:阴性阳离子型,阴离子型,非阳性离子型和两性离子型。阳离子型主要基于盐酸季铵盐,具有良好的表面活性和对微生物的抗降解性。

commonly used Gemini coupling surfactants can also be referred to as double coupling surfactants,double coupling surfactants or coupling Gemini surfactants.They are also new surfactants for human body surface oxidation.The molecular structure of surfactant group is directly formed by continuously combining groups close to the hydrophilic base area or groups close to the hydrophilic base area.Considering the chemical properties of each hydrophilic group,Gemini surfactants can be divided into four types:negative cation type,anion type,non positive ion type and amphoteric ion type.The cationic type is mainly based on quaternary ammonium chloride,which has good surface activity and biodegradation resistance to microorganisms.
