application
1.It is suitable as corrosion-resistant insulation material
2.It is suitable as thermal insulation materials
In China most enterprises introduce the intermittent process to produce the thick mucilage-based carbon fiber felt, its shortcomings are the quality of the productions and the uniformity are not good, poor stability, the flatness is difficult to achieve the uniform standards and specifications can not be satisfied with the requirements of large installations. We synthesize its advantages and disadvantages, in the process route with all the company's horizontal furnace, and in process, we take special measures to heat and protect the critical temperature range in order to guarantee and improve the uniformity and flatness of the productions, enhance the stability of the process, effectively improve the quality of the products.
The raw material of the thick mucilage-based carbon fiber felt is the viscose fiber, obtained by the pre-oxygen, high-temperature carbonization process. It is a excellent high-temperature insulation materials, which not only has the other types of general characteristics of the carbon felt, but also has the low-density, low thermal conductivity, high temperature resistance, corrosion resistance, electrical conductivity and a series of excellent performance.It is suitable as thermal insulation materials, corrosion-resistant materials, and processed into graphite carbon felt.
