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
The micellar structure of silica sol is introduced. The micelles consist of rubber core, adsorption layer and diffusion layer. The water in the silica sol is composed of 3 parts of free water, adsorbed water and structural water. The water loss rate and gelation range of silica sol gel began to be calculated
