It is established that a change in carbon fiber treatment temperature from 1600 to 2400°C may lead to an increase in materials thermal conductivity by 0.21 W/(m·K) for each 100°C. Adifference in framework structure may change average thermal conductivity within the limits of 3 W/(m·K...
Carbon fiberis produced from a precursor fiber such as rayon,polyacrylonitrile(PAN), or mesophase pitch. The precursor is thermally decomposed, followed by heat treatment at high temperature to convert it to carbon. For example,PANprecursor fiber is first oxidized at 250°C, then carbonized at 80...
The original CFs are divided into two types: one is CF, which is prepared in the temperature range of 1000–1500 °C; the other is called graphite fiber, which is prepared above 2000 °C. In the process of development, the differences between them have been removed, and both are consider...

The catalysis of the activated carbon fiber (ACF) during the course of flue gas desulphuration was studied by XPS atlas analysis,determination of the rate of conversion of SO_2 into H_2SO_4 and a verification of long period test.The results showed that ACF had a stronger catalytic capacity...
For example, optical fiber uses 60 percent to 75 percent less energy than copper. To help global operators better fulfill their social responsibility for low-carbon development, Huawei will continue to promote green innovation in fiber networks, breaking through theoretical limits and developing greener...
2450 K when the temperature of the furnace walls is ca. 2420 K. Calibration curves have been obtained for Al, Mo and Cr, each showing a useful working range. The detection limit for Al was 5 pg, and for Cr and Mo was 140 pg. Bismuth was found to give a poor detection limit (10...
