( 2 ) thermodynamic unstable system : using mechanical churn up method and surfactants , diesel fuel and alcohols ( sometimes with water ) can be emulsified . in this part , the optimum hlb number and the delamination period , related to the scale of water in mixture fuel , are studied 本文采用机械搅拌方式对柴油-醇-水-表面活性剂的混合液进行乳化,得到了不同配比的柴油-醇-水乳化液,分析和研究了含水量对柴油-醇-水乳化液的最佳hlb和分层时间的影响。
( 2 ) the reaction factors optimized by orthogonal tests are : the emulsion polymerization temperature is 60 , the reaction time is 3 hours , the amount of emulsifier is 8wt % , the hydrophile lipophile balance ( hlb ) value of emulsifier is 15 , the stirring speed is 4000r / min , the dropping speed is 1 . 1g / min 用正交实验确定的最佳聚合反应工艺参数为:水解温度60 ,水解聚合时间3h ,乳化剂用量8wt ,复合乳化剂hlb值为15 ;搅拌速度为4000r min ,滴加速度为1 . 1g min 。
By adopting x - ray diffraction and transmission electron microscope ( tem ) , this thesis has insepectd the size and the structure of the calcium carbonate ( caco3 ) particles . according to hydrophile and lipophile balance ( hlb ) , the suitable surface - active agents have been selected and put into lubricating oil with nanometer caco3 particles 本文采用x射线衍射仪和透射电镜检验了纳米碳酸钙粒子的粒径和内部结构,根据亲水亲油平衡值( hlb ) ,选择合适的表面活性剂将其加入到含有纳米碳酸钙粒子的润滑油中进行表面改性。
( 1 ) thermodynamic stable system : in this part , many experiments have been done in order to get the data of alcohols " soluble capacity in diesel fuel , the solubilizing power of some solubilizing agents , the effects of surfactants " hlb number and water on the mixture fuel stability ( 1 )柴油与醇形成热力学上的稳定体系。本文通过大量实验比较了醇与柴油的相溶能力、多种助溶剂对柴油-醇的助溶效果、表面活性剂的hlb值对柴油-醇的增溶效果的影响以及水对这种热力学上的稳定体系的影响。
