Tego 型杀菌剂的制备方法及应用讨论 摘要 Tego 型杀菌剂是一类新型的杀菌灭藻剂,是两性表面活性剂的一种,具有广谱性的杀菌能力,低毒性和污泥剥离作用,符合现代药剂高效低毒要求。通过对它的制备方法和产品性能以及国内外讨论成果和用途的介绍,发现它对革兰氏阴性细菌和革兰氏阳性细菌等多种细菌具有很强的杀菌力,且使用的范围很广,与其他杀菌灭藻剂相比较,具有极低的毒性,对皮肤和眼睛没有刺激性,将成为一种广泛应用的高效低毒的杀菌灭藻剂。关键词杀菌灭藻剂 两性表面活性剂 污泥剥离剂 高效 低毒Preparation and Application of Tego BactericidesAbstract: As new germicidal agents, the Tego bactericides belong to the amphoteric surfactants. They have such virtues as broad spectrum bactericidal effect,low mammalian toxicity and sludge stripping effect etc. Consequently, they meet the demands of the modern germicidal agents. The preparation procedures and the characteristics and applications of the Tego bactericides were introduced here. It can be concluded that the Tego bactericides can be applied in many fields. Compared with the other germicidal agents,they have low mammalian toxicity. Moreover, they thus do not cause eye and skin irritation. The above advantages of the products will broaden the wide application of the Tego bactericides.key words: Germicidal agent; amphoteric surfactants; sludge stripping agent; high-performance; low mammalian toxicity1 引言 目前工业循环冷却水系统中,微生物产生的障碍比较突出。微生物在管壁上的生长繁殖,使水质恶化,也大大增加了水流的阻力,引起管道的堵塞,还严重地降低了热交换器的传热效率,甚至造成垢下腐蚀,以致使管道穿孔,设备报废,发生停产检修等等事故。为了控制微生物的生长及其造成的危害,就必须投加杀菌灭藻剂、污泥剥离剂。目前对药剂高效低毒的要求越来越高了,因此要立足于污泥、污垢剥离,以抑制菌藻繁殖和减少他们的危害。常用的污泥剥离剂有松香胺和一些两性剥离剂。[1-3] 羧酸型 α-亚氨基乙酸系两性表面活性剂,即 N-烷基甘胺酸系,其开发最早并...
