calcium bentonite meaning in English

钙基膨润土
钙系膨土

According to direct and indirect testing results of organobentonite ' s structure and performance , the project that synthesize new organobentonite with calcium bentonite by replacing a part of conventional modifying agent for caprolactam has been proved reasonable and feasible , the affinity of organobentonie for organic substance was improved , it can be used in variable organic system
通过以上对有机膨润土结构和性能的直接表征和间接评价，证明以钙基膨润土为原料，用己内酰胺取代部分季铵盐制备新型有机膨润土的方案是合理的、可行的，制备的有机膨润土具有对有机物良好的亲和性和相容性，可用于各类有机体系。
However , the reserves of calcium bentonite is low and the surfactants are expensive , which bring many difficulties to industrialization . in this paper , an abundant and low cost raw material , calcium bentonite , and several new modifying agents such as compound quaternary ammonium salt with cheap caprolactam or anionic surfactant or silane coupling agent were used to synthesize new - type organobentonites , in the principal of efficient , cheap and simple
作者尝试以资源十分丰富的钙基膨润土为原料，依据高效、廉价、使用简单的原则，以传统插层剂季铵盐为基础，分别用价格较低的己内酰胺、阴离子表面活性剂、硅烷偶联剂部分取代季铵盐作插层剂，来制备新型的有机膨润土。
