憎水基

研究结果表明：水溶性破乳剂的脱水作用取决于它的分子憎水基的润湿程度，亲水性材料可使其润湿性得到改善，因而有利于原油脱水。

Hydrophilicity materials could improve its wettability , therefore it is favourable to crude dehydration .

在分子结构上引入憎水基-苯环后，显著提高了脲醛树脂的耐水性。

The hydrophobic property of the resin has remarkably improved by adding the hydrophobic group of benzene ring to the molecular structure of the resin .

因为在模板剂中引入有机添加物，或增加碳链长度时，胶束憎水基体积增大，引起直径膨胀变大，从而所得样品孔径增大。

As the addition of organic addition or increasing of surfactants ' carbon chain , the volume of micelle increases , so does the diameter , which leads to increase of pore size .

研究一种以市售聚硅氧烷乳液为基料，辅以催化剂金属盐和水溶性缓蚀剂制备出可对预处理过的A3钢试样进行憎水处理的水基有机硅憎水剂。

The pretreated A3 steel was treated by a water-borne silicone water repellent agent which is prepared by a metal salt catalyzed reaction of a commercial water-borne silicone emulsion with a water soluble corrosion inhibitor .
