Rubber industry In the rubber industry, carbon black reinforcement is already a very mature technology and is widely used. At present, it has developed into a non-traditional single carbon black reinforcement. In recent years, there have been many substitutes for ordinary carbon black, such as white carbon black. Studies have shown that in the carbon black reinforcement process, the specific surface area of ​​the reinforcement agent except for micropores has a very important effect on the reinforcement performance. Therefore, in the carbon black industry, it is usually necessary to measure the external specific surface area of ​​the reinforcing agent to measure its performance.
The construction industry China is currently in a period of great development in the construction industry. High-quality construction is inseparable from high-quality cement. Cement acts as a binder, and its bonding performance is closely related to its specific surface area. Before the gas adsorption method became popular, the early measurement of the specific surface area of ​​cement was carried out using the Brinell method, and the results of this measurement method generally had large errors. With the improvement of cement production technology and the higher requirements placed on the quality of modern buildings, the results of the Brinell method determination are gradually unable to meet its accuracy requirements. It is a general trend to use the gas adsorption method with higher precision to measure the specific surface area of ​​cement.
With the development of industrial technology in the battery industry, energy issues have increasingly become the focus of social concern. The exhaustion of non-renewable energy sources and the resulting environmental pollution have forced humans to find new alternative energy sources. Electric energy, especially energy storage batteries, is generally favored by people because of its low pollution and renewable characteristics. It is most likely to become an alternative energy source in the future and has broad development prospects. The key part of energy storage batteries-energy storage materials, because of its special requirements for energy storage, the specific surface area performance of the material is very strict, too large or too small are detrimental to the performance of the battery, so the specific surface area becomes the most important electrode material Physical performance index.
In the chemical industry, many products in the chemical industry require catalysts, and catalyst development has a long history. With the development of material technology, the performance of the catalyst is becoming more and more powerful. In addition to its chemical composition, the most important determinants of the catalytic performance of a material are its specific surface area and pore volume, as well as its surface morphology and structure. Catalytic materials generally have large specific surface areas and are porous materials, both of which can increase the contact area between the catalyst and the reaction material, thus greatly improving the catalytic performance. The specific surface area and pore volume are important performance indicators to measure the performance of the catalyst.
With the continuous development of material technology, the performance measurement of specific surface area and porosity (pore volume) is also widely used in many other industries, such as electromagnetic materials, fluorescent materials, ceramics, powder metallurgy, adsorbents, Cosmetics, food, etc. For granular materials, specific surface area gradually becomes the same important physical property as particle size.
