It is useful to reduce the occurance of acid mist by adding erosion retardant and surface activity into acid which has been used in some industries.in the developed province and city, the bureau for enviroment protection calls on all enterprises to process the heated zincification water and prohibit from drainage, all enterprises should process the rinsed waste water and plating-aid waste water,however it remains to be strengthened across the country for the process of three wastes come from heated zincification

在酸中添加缓蚀剂和表面活性剂可以减少酸雾的产生，已在一部分企业中得到应用。在发达省市，环保部门要求企业必须对热镀锌废水进行治理，不得外排，企业对漂洗废水、助镀废液均进行处理，但全国范围内对热镀锌的三废治理还需加强。

Their structures were confirmed by IR, and the properties of these surfactants such as acid number, interfacial tension, and critical micelle concentration and so on were studied.

通过红外光谱确定了产物的结构，并对有机硼表面活性剂的酸值、表面张力以及临界胶束浓度等性能进行了研究。

The tests show that it has effective broad spectrum bactericidal action and good compatibility with ionic or/and nonionic surfacants at concentration of 0.02-0.05%. It is really toxicless and effective in the range of pH value for cosmetics .

实验证明：Kathon CG对细菌、酵母菌和霉菌具有广谱抗菌活性；使用浓度为0.02~0.05%；可与所有离子型、非离子型表面活性剂配伍；在含有蛋白质的化妆品中的用重要加大；在化妆品中一般所遇到的pH范围都有效；在使用量下无毒。
