Project Description

Pitch-based carbon fiber is made of carbon, which belongs to inorganic fiber in high performance fiber. It has the characteristics of light weight, high strength, good stiffness, high temperature resistance, ablative resistance, chemical corrosion resistance, fatigue resistance, high conductivity and heat conduction, flame retardant and low expansion coefficient.

Pitch-based carbon fiber is a non-metallic materials with better thermally conductive. Heat transfer of solid materials mainly rely on the free electrons, and the heat transfer of carbon fiber mainly relies on the lattice vibration, the essence of which is thermal motion of microscopic particles, molecules, atoms and ions, it conforms to the motion law of quantum mechanics, hot components through the electronic movement, thermal effect come out under the condition of electric spark motivation, and it is silent, no light and no pollution in the entire movement process.

Carbon fiber rigid insulation materials applied in high temperature materials industry and it is our company self-developed product.  It is through dipping environment-friendly adhesive in petroleum pitch based carbon fiber, after processing, it is carbonized (graphitized) at high temperature. And its characteristics are with firm fiber structure, resistance to air scour, not easy pulverization, strong self-supporting, uniform density, excellent heat-shielding, low thermal capacity. It is mainly used in high temperature and Ultra-high temperature field, such as metal heat treatment furnace, sintering furnace, monocrystalline silicon sintering, crystal growth furnace, fiber optic production, inert gas protection furnace, and other industrial furnaces with high working temperature or high atmosphere requirements. The pitch based carbon fiber needled solidified mat can be used in the monocrystalline silicon, polysilicon compound semiconductors, optical fiber, quartz molten high temperature crystal growth furnace, graphite metallurgy, heat treatment furnace body of high temperature and ultra-high temperature insulation material which can protect the furnace body and control the temperature inside the furnace.

Carbon fiber mesh felt: After grinding and cutting, Carbon fiber mesh felt can be used to make various Carbon fiber deeply processed products. Or it can be made into ACF filtering products after direct-activating. It can be applied in all kinds of resin, paints, rubbers, cements and other materials, which has good conductive effect. Meanwhile the strength and abrasion resistance of the product are greatly improved. So the carbon fiber mesh felt will be the ideal substitute for other conductive materials. In addition, it also can be used to make heat preservation, flame-resistant, wear-resisting, sealing and antistatic composite materials and needled non-woven felt

Use carbon fiber reinforced Teflon material to make anti-corrosion, anti-abrasion and anti-high temperature sealing rings or packing. Its works life will be longer when use for static sealing, typically its life is 10 times years longer than general asbestos packing. It can always keep sealing performance under the condition of load change, quick cooling and quick heating. Besides, there is no pitting corrosion will occur on the metalas the material does not contain corrosive substances.

Due to it has the characteristic of self-lubrication, it can be made for special purpose bearings, gears and piston rings. For example, oil-free bearing foraircraft instrumentation and tape recorder, oil-free gear (It can avoid accidents caused by oil leakage) for electric – driven diesel locomotives, Oil-free piston ring on compressor, etc. In addition, It also has the advantage of being non-toxic, used in food and medicine industry as sliding bearings or seals.

Use for the STRUCTURAL MATERIAL of Aerospace, aviation, missiles. Carbon fiber reinforced plastic (CFRP) has been developed rapidly since it came out in the 1970s. It has been widely used in chemical, petroleum, electric machinery and other industries, as a rotating or reciprocating dynamic seal or a variety of static seal materials.
