摘要

介绍了硅溶胶的胶团结构

胶团由胶核、吸附层和扩散层组成。硅溶胶中的水分由自由水、吸附水和结构水 3部分组成。计算了硅溶胶开始胶凝的失水率和胶凝区范围

Abstract

Structure of colloid aggregation in silic sol was in troduced. The colloid structure consists of colloid core

absorbent layer and di ffusional layer. Moisture in silic sol is composed of free water

absorbent water and structure water. Water-loss rate and range of colloid concretion zon e of silic sol during initial colloid concretion were calculated.
