表面活性剂在家用洗涤剂中的应用

表面活性剂是具有表面活性的物质,能改变物质的表面张力。表面活性剂的分子都是由亲水基和疏水基构成,大部分能溶于水,产生润湿、乳化、渗透、发泡、去污等作用。家用合成洗涤剂所用的表面活性剂主要要有去污能力,同时还考虑乳化、发泡等各项性能的综合效应。在目前的洗涤剂中仍大量使用阴离子表面活性剂,非离子表面活性剂的用量正在日益增加,阳离子表面活性剂则被大量用于洗涤后处理,两性离子表面活性剂使用量较少。随着洗涤剂越来越专用化,表面活性剂的品种数量也在飞速发展。

Surface Active Agent in Home Use Detergent Application

Surfactants are surface active substances which can change the surface tension.Surfactant molecules have hydrophilic and hydrophobic radical.Most of surfactants can be soluble in water and take part in wetting,emulsification,penetration,foaming,cleaning and so on.Surfactants in household synthetic detergents have capabilities of decontamination mostly and also have emulsification,foaming and other combined properties.At present anionic surfactants are still largely used in detergents and nonionic surfactant...
