对硅胶的孔容、孔径、比表面、粒度、粒度分布、堆积密度、表观密度、骨架密度等建立了简易的测定方法。比电子显微镜、X 光衍射等测定方法设备简单,具有一定准确度。这些方法亦适合于多孔无机催化剂及载体有关物性的测试。 A simple method for the determination of pore volume, pore size, specific surface area, particle size, particle size distribution, bulk density, apparent density and skeleton density of silica gel was established. Compared with electron microscopy, X-ray diffraction measurement method equipment is simple, with a certain degree of accuracy. These methods are also suitable for porous inorganic catalysts and carrier-related properties of the test.
