Effect of additives on cloud point of polyoxyethylene octyphenyl ether nonionic surfactant 添加剂对聚乙二醇辛基苯基醚浊点的影响
Study of preparation of polymer surfactant of ester - salt of copolymaleic anhydride with nonyl phenyl polyoxyethylene ether 新型高分子表面活性剂马莱酸壬基酚聚氧乙烯酯盐类的合成研究
Several polyoxyethylene type quaternary ammonium salt cationic surfactants were selected to investigate their interaction with acid dyes and influence on the dyeing properties 摘要选择了几种聚氧乙烯型季铵盐阳离子表面活性剂,探讨了这些表面活性剂与酸性染料的相互作用以及对染料染色性能的影响。
The relation of absorption of nano - metal sols and the addition of dispersants , as well as the rule of absorption of nano - metal sol added by dispersants concomitant to placing time were systematically investigated by means of uv - vis . the results show that , the suitable dispersant to nano - iron / ethanol sol is 0 . 035 % polyoxyethylene ( 10 ) lauryl ether ( op - 10 ) , but in the case of nano - tungsten / ethanol sol , 0 . 13 % neotelex maybe is of more benefit to its disperse stability . the observation of tem shows the best evidences Uv - vis法理论分析结果表明,对于纳米铁溶胶,添加0 . 035的非离子型表面活性剂十二烷醇聚氧乙烯醚可以达到良好的分散稳定性;而对于纳米钨溶胶,最理想的分散剂则是0 . 13的阴离子表面活性剂十二烷基苯磺酸钠,电镜观察结果完全证实了该推论,显示5天后的纳米金属溶胶仍然保持良好的分散状况。
By adding definite chirality reagent the lcd reflection wavelength is changed and the voltage is increased . by adding a bit of active reagent such as polyoxyethylene sorbitan monooleate , polyoxyethylene sorbitan trioleate , glyceryl momostearate and so on , the lcd response velocity is remarkably improved . the lcd response velocity is increased about 200 times 通过加入一定量的手性剂改变了液晶显示器反射波长、提高了相变电压等性质;分别加入少量活性剂吐温80 、吐温85 、单硬脂酸甘油酯显著提高了液晶显示器的响应速度,其响应速度提高了200倍左右。
