聚炳烯腈基石墨毡：优质聚炳烯腈基石墨毡是炭毡经特殊高温石墨化处理后获得的,高温处理时炭毡在任意两点间的温差不会超过50℃。

High quality PAN Graphite Felt is gained by carbon felt and through special high temperature graphitization. During high temperature treatment, the temperature difference between any two point of carbon felt will never be more than 50℃.

（1） 石墨毡的特性和应用

特性：*导热系数小，热容量低，有利于绝热，节约能源，缩短设备升降温时间。

*不吸附水气，有利于缩短抽真空时间

*使用温度高，在真空状态下可为2500℃，在惰性气氛下为3000℃

*纯度高，不会对被处理工件造成污染

*易于加工，可用小刀切成所需形状

应用：*宇航工业：热等静压炉，热处理，烧结，钎焊，热压炉。

*半导体行业：拉制硅单晶炉，镓砷产品用炉。

*金属热处理：热处理炉，烧结炉，钎焊炉。

*炭纤维生产：感应加热或者电阻加热的炭化炉，石墨化炉。

*复合材料生产：热解炭和热解石墨的化学气相沉积，或其他材质的复合材料。

*能源材料：钒或其他氧化还原电池用材。

Characteristic and application of graphite felt

Characteristic:

*Lower thermal conductivity and specific heat help improve the hear insulation and save energy consume and reduce the duration of rise or lower temperature when equipments running well.

*Not adsorbed moisture then beneficial to reduce the time as extract vacuum.

*High application temperature up to 2500℃in vacuum furnace and up to 3000℃in inert.

*High purity that have no pollution effect upon the treated material.

*Easily to processing may be cut into the size by a small knife.

Application include:

*Aerospace industry:Hot isostatic process furnace, heat treating ,sintering, brazing and autoclave furnace.

*Semiconductor trades:Silicon puller and gallium arsenate produces.

*Metal heat treatment:Heat treatment furnace,and sintering,brazing furnace.

*Carbon fiber manufacture:Carbonizing furnace and graphitizing furnace with induction or resistance hearing.

*Composite fabrication:CVD or CVL equipments for deposition or infiltrantion by pyrolytic carbon and pyrolytic graphite or other suitable elements.

*Energy source material:Used for vanadium or other redox flow buttery.
