氟表面活性剂的工业应用

介绍了氟表面活性剂的分类、结构及性质;主要综述了由于氟表面活性剂具有"三高"、"两憎"的独特性能,广泛应用于消防、皮革、石油、造纸、纺织印染及金属材料加工等工业领域,起到普通碳氢表面活性剂所不能的作用;指出了根据应用领域的不同,应从分子结构设计入手,有针对性地、有目的地研发氟表面活性剂新品种新工艺,拓展应用领域,注重氟表面活性剂与普通表面活性剂的复配研究。

Industrial applications of fluorinated surfactants

Classification,structure and properties of fluorinated surfactants were introduced.Due to their unique properties,such as high surface activity,high thermal stability and high chemical stability as well as both hydrophobic and lipophobic properties,fluorinated surfactants are widely used in various industrial sectors such as fire-fighting,leather,petroleum,paper making,textile dyeing and printing as well as metal processing et al.In some cases,they can display performance that is beyond the capability of common hydrocarbon chain based surfactants.According to requirement with respect to different application fields,new varieties of fluorinated surfactants and new preparation technology should be developed based on molecular design for special targets and purpose,to expand their application fields.Attentions are worth to be paid to the performance of blend of fluorinated surfactants with hydrocarbon chain based surfactants.
