BET specific surface area and total pore volume in carbon black and white carbon black industry

Black carbon black (including carbon black, carbon black, referred to as CB) and white carbon black (silica, SiO2) industry are important applications in the field of physical adsorption (specific surface and pore analyzer) testing.

The carbon black industry needs to calculate the important carbon black surface area (STSA for short). The instrument is calculated by selecting the STSA model in the t-plot thickness layer correction. Generally, the STSA will be slightly smaller or closer than the BET specific surface area. The national standard was announced in 2003. The new carbon black total surface area and external surface area measurement standard: GB/T 10722-2003.

Silica (silica, SiO2) is mainly classified into a gas phase method and a precipitation method of white carbon black according to a production process. White carbon black is mainly used in silicone rubber, paint, rubber reinforcement, light-colored rubber (shoes, etc.), toothpaste friction agent and thickener. In recent years, white carbon black has also developed as a energy storage material in the field of new energy. . The 3H-2000PS series static capacity ratio surface porosity analyzer from Bestech Instruments (Beijing) Co., Ltd. provides high reproducibility BET specific surface area and total pore volume test of silica, and the relative pressure point of total pore volume P/ P0 reaches above 0.997, and provides pore volume, pore area to pore size distribution, and is cost-effective and low in cost of use.

In recent years, highly dispersible white carbon black has developed faster and faster in the field of “green tires”. The conventional silica has a median particle size of about 10 microns, and the high-dispersion silica has a median particle size of 5 to 6 microns. The US-based Mickey laser particle size analyzer and particle size are represented by Dachang Huajia. The particle analyzer can provide more information on this.
