Carbon Fiber Felt

There are three main types of carbon fiber felt, namely polyacrylonitrile based carbon felt, adhesive based carbon felt, and asphalt based carbon felt. Among them, polyacrylonitrile based carbon felt is widely used, and what we generally refer to as carbon fiber felt is polyacrylonitrile based carbon felt. Polyacrylonitrile based carbon felt can also be divided into two types: polyacrylonitrile based acrylic fiber carbon felt and polyacrylonitrile based (precursor) carbon felt. Their difference lies in one being made from acrylic fiber, and the other being made from carbon fiber raw materials. The former has poorer performance than the latter, with better strength, feel, grayscale, and limit compared to polyacrylonitrile based (raw silk) carbon felt. If the processing methods are different, the shape of carbon fiber felt will also be different. There are them made from short cut carbon fiber, it made from pre oxidized fiber, and it made by re oxidizing and carbonizing the produced carbon felt.

Taking polyacrylonitrile based carbon felt as an example, with an area weight of 500g/m2 and 1000g/m2, longitudinal and transverse strengths (N/mm2) of 0.12, 0.16 and 0.10, 0.12 respectively, fracture elongation of 3%, 4% and 18%, 16% respectively, electrical resistivity (Ω · mm) of 4-6, 3.5-5.5 and 7-9, 6-8 respectively, thermal conductivity of 0.06W/(m · K) (25 ℃), specific surface area of>1.5m2/g, ash content of less than 0.3%, and sulfur content of less than 0.03%.

The single crystal furnace currently produced by our company uses thermal field materials that have been purified under high temperature and special atmosphere, and the purity can be customized according to customer needs. Among them, carbon felt graphite felt has been improved, with a surface that does not prick hands, does not shed slag, high purity, and good insulation properties. Meanwhile, after three years, a highly sealing graphene carbon nanotube coating slurry has been successfully developed, which can withstand temperatures of 3200 ℃ for a long time and has been applied in multiple enterprises.

Viscose based carbon fiber felt is a high-performance high-temperature insulation material made from viscose artificial silk as raw material.
It has the general characteristics of other types of carbon felt
It also has the characteristics of low density and low thermal conductivity, making it suitable for use as insulation materials and corrosion-resistant materials.
Especially suitable for medium frequency induction high-temperature sintering furnaces and occasions with strict requirements for insulation performance, it is also suitable as a heating element material for quartz heating tubes and felt for marking machines.
