【专业品质】供应保温材料--[石墨毡桶材、板材] 规格可定制
由碳纤维布、石墨纸、石墨毡等其他材料经特殊工艺沾合、固化、定型,数次高温热处理制得,具有一定的形状保持性、自支撑性、比重小、无短纤脱落、导热系数低、抗热震性、耐烧蚀、使用寿命长,便于安装拆除。适用于真空高压气淬炉、真空烧结炉、加压真空烧结炉。
Our tubbing and plates are made from carbon fiber sheets, graphite paper and felt and some other materials with some special processes to conglutinate, solidify, and stereotypical via times of high temperature heat treatment. They have some unique properties such as shape retention, self-support, low intensity, no fall off of staple fiber, low pressure gas quenching vacuum furnace, vacuum sintering furnace, pressure vacuum sintering furnace.
