硅表面活性剂

岩芯的X射线光电子能谱分析显示，纳米聚硅和表面活性剂能吸附在岩石表面上，改变岩石表面的润湿性，提高水相相对渗透率。

According to the result of XPS , the nanometer polysilicon and the surfactant can adsorb on the rock surface , change its wettability , and enhance the water relative permeability .

利用硅烷偶联剂APS和活性硅作表面活性剂，采用种子包埋法，制备了纳米铁/SiO2核壳复合粒子。

The Nano-SiO 2-coated-iron composite powder was prepared by the seeded growth process with 3-aminopropyl-trimethoxysilane ( APS ) and active silica as surfactant .

破乳条件为：醚型表面活性剂9901和含硅型表面活性剂SAE的复配物0.10g，无水碳酸钠0.10g，搅拌时间15min。

The optimum emulsified conditions are : 0.10 g of sodium carbonate , 0.10 g of surface active agents which include polyether and silicon , and 15 minutes for stirring .

在碱性条件下，采用水热晶化法，以水玻璃为硅源，表面活性剂十六烷基三甲基溴化铵为结构模板剂，成功合成出全硅MCM-41中孔分子筛。

Under the alkaline condition , the synthesis of mesoporous molecular sieves MCM-41 had been accomplished successfully in a hydrothermal system using sodium silicate as the source of silicon and surfactant C16H33 ( CH3 ) 3NBr as structural template .
