Test study on two biocides , namely quaternary ammonium salt and isothiazolinelcetone , commonly used in circulatory cooling water system has been carried out , obtaining the relationship among dosage , actuation time duration , and the killed persontage , and putting forward the principle and points needing attention for selecting the biocide 摘要对火电厂循环冷却水系统常用的两种杀菌剂季胺盐及异噻唑啉酮进行了试验研究，得出加药量、作用时间与杀菌率的关系，并提出杀菌剂的选择原则和注意事项。
Moreover , we prepared epoxy / bentonite nanocomposites using conventional organbentonite and quaternary ammonium salt / caprolactam modified organobentonite as harbinger respectively . their mechanical performance were tested . the bend strength and modulus of conventional epoxy / bentonite nanocomposite are 73 % and 52 . 4 % higher than those of pure epoxy , while the bend strength and modulus of new epoxy / bentonite nanocomposite are 95 . 6 % and 64 . 2 % higher than those of pure epoxy 与纯环氧树脂固化物相比，传统有机膨润土制备的纳米复合材料的弯曲强度和弯曲模量分别提高73和52 . 4 ，而新型有机膨润土制备的环氧树脂/膨润土纳米复合材料的弯曲强度和弯曲模量分别提高95 . 6和64 . 2 。
Anji yuhong clay chemical co . , ltd . has passed iso9001 and have perdected quality controlled system , there are 3 production line of automatic or semi automatic . we output 8000 ton betonies clay of yh series , 3000 ton inorganic gelatinate of yh series , 15000 tons used in water paint betonies clay of yh series , 35000 tons of casting betonies clay of yh series , 4000 tons 18311827 negion quaternary ammonium salt of series 有自动化半自动化生产线三条，年产yh系列有机膨润八千吨yh系列无机凝胶三千吨yh系列水性涂料用膨润土五千吨yh系列土木工程膨润土壹万吨yh系列铸造用膨润土三万五千吨yh系列1831 1827等阳离子季铵盐四千吨。
It indicated that the color removal of new organobentintes are much higher than that of inorgnganic bentonite , the color removal of the organobentonite prapared by a certain proportion of quaternary ammonium salt and caprolactam is the best , 96 . 06 % , it is 11 . 86 % higher than that of actived carbon 结果表明，各类新型有机膨润土对印染废水的脱色率均远远高于无机膨润土的脱色率，季铵盐/己内酰胺复合插层有机膨润土的脱色率最高，达96 . 06 ，比活性炭的脱色率高11 . 86 。
Chiral quaternary ammonium salts were synthesized from cinchonine in cinchona alkaloids using chloromethylated polystyrene - polyethylene glycol , diethylene glycol , triethylene glycol and glycol as polymer - supported phase transfer catalysts , finsl products were characterized by ftir , elemental analysis , scanning electron microscopy , x - ray photoelectron spectroscopy ( xps ) 摘要以金鸡纳生物碱中的辛可宁为原料，氯甲基化聚苯乙烯聚乙二醇、一缩二乙二醇、二缩三乙二醇、乙二醇等为载体合成了几种聚合物负载的手性季铵盐，并对它们的结构用红外光谱、元素分析、扫描电镜和x射线光电子能谱等测试手段进行了表徵。
