在医药、石油化工中的固体催化剂,防毒过滤用的吸附剂,建筑材料用的水泥,陶瓷、钢铁冶炼及粉末冶金工业中的原料,化学电源的电极等都是固体粉末或多孔物质。这些固体具有很大的比表面积及很多大小不等、形状不同的孔隙。在使用过程中,它们的物理及化学过程都是在这些表面及孔隙中进行的,在生产与科研工作中测定固体的比表面积及孔径分布参数具有非常重要的意义。ST-03型比表面积测定仪,是根据低温吸附原理,对固体的比表面积及孔径分布进行测定的仪器。
In the pharmaceutical and petrochemical industry, solid catalysts, adsorbents for anti-virus filtration, cement for building materials, ceramics, raw materials for steel smelting and powder metallurgy industries, and electrodes for chemical power are all solid powders or porous materials. These solids have a large specific surface area and many different sizes and shapes of pores. In the course of their use, their physical and chemical processes are carried out on these surfaces and pores. It is of great significance to determine the specific surface area and the pore size distribution parameters of solids in production and scientific research. ST-03 type surface area analyzer, is based on the principle of low temperature adsorption, the solid surface area and pore size distribution of the instrument.
