摘　　要：通过设计正交试验,全面考察了拟薄水铝石制备条件对其胶溶性能的影响,结果表明温度是最重要的影响因素。X射线衍射、傅里叶变换红外光谱和扫描电镜表征结果说明,对不含三水铝石等杂质的拟薄水铝石,其胶溶性能主要取决于颗粒聚集方式和尺寸大小。By designing the orthogonal test,the influence of the preparation conditions of pseudo-boehmite on its peptization performance was thoroughly investigated.The results show that the temperature is the most important influencing factor.The characterization results of X-ray diffraction,Fourier transform infrared spectroscopy and scanning electron microscopy indicate that for the pseudo-boehmite without containing gibbsite and other impurities,its peptization performance mainly depends on the aggregation mode and size of the particles.
