石墨硬毡（Hard composite graphite fiber felt）
采用特殊工艺将石墨纸、PAN基石墨毡、碳布合为一体、固化定型，二次高温纯化处理制得，石墨硬毡纯度高、碳含量高，抗烧蚀性能、抗热震性能、而气流冲刷和隔热、保温性能都很优越，主要适用于超高温真空高压烧结炉以及电子、半导体行业、太阳能光伏（多晶浇铸炉、单晶炉）等真空工业炉设备。
The material is formed by integrating graphite foil,carbon felt and carbon cloth,and then subjecting them to secondary high temperature purification treatment.The material is superior in ablation resistance performance,thermal shock resistance performance,airflow washing proof performance and thermal insulation performance.It’s mainly used for vacuum high pressure air puenching furnace,low pressure fritting furnace,pressurization vacuum sintering furnace temperature,solar industry,vacuum furnace,single crystal furnace,multicrystalline Dss.
