通过热重分析、物相分析(X 射线分析、差热分析、红外光谱分析)及胶溶指数的测定,论述了拟薄水铝石胶溶性能和其组成结构的关系,从而提出控制产品质量的特殊要求.从胶溶性能的研究出发,通过求脱附活化能,论证了拟薄水铝石中存在一部分“额外水,”这部分水界于表面吸附水和结构水之间,靠氢键吸附在胶体表面上的非自由水分子.
The relationship between the peptization properties and the composition and structure of pseudoboehmite was discussed through the methods of thermogravimetric analysis, phase analysis (X-ray analysis, differential thermal analysis, infrared spectroscopy) and the determination of peptization index From the study of peptization properties, through the desorption activation energy, it is demonstrated that there is a part of “extra water” in the pseudo-boehmite, which is between the surface adsorbed water and structural water, Bond adsorbs non-free water molecules on the surface of colloids.
