有机化钙硅胶的制备和性质

Preparation and Properties of Organized Calcium-Silica Gel

通过阴离子表面活性剂(SAS、SDS和SDBS)在钙硅胶上的吸附研究了有机化钙硅胶的制备。测定了此硅胶的Zeta电位、差热分析,红外光谱、物理结构、润湿热、接触角、热稳定性和水解稳定性、并对实验结果进行了讨论。

Preparation of organized calcium-silica gelsby using the adsorption of anionic surfactants such as SAS,SDS and SDBS on calcium-silica gel was studied. The Zetapotential, DTA, IR, Physical structure, heat of wetting ,contact angle,thermal stability and hydrolytic stability forthe silica gels were determined. The experimental resultsobtained were discussed.
