CS-G876 陶瓷纤维垫片是由精选硅酸铝陶瓷纤维棉为主要原料,采用湿法成型工艺制成的陶瓷纤维纸板冲切或裁剪而成。在传统工艺基础上改善了除渣和烘干工艺,其特点为无石棉、纤维分布均匀、色泽洁白、无分层、渣球少(四次离心除渣)、容重依据用途灵活调整、强度大(含增强纤维)、弹性好、机械加工性强。硅酸铝陶瓷纤维垫片不仅能耐高温(1260℃)而且具有很低的热传导性是一种理想的绝缘隔热材料。适用于高温环境下的隔热、保温、密封、电绝缘、吸音、过滤等。
CS-G876 Ceramic fiber gasket is selected aluminum silicate ceramic fiber cotton as the main raw material,Ceramic fibre sheet cut or cut.Based on the traditional process, the slag removal and drying process were improved,Its characteristic is asbestos-free,Uniform distribution of fibers,White color,No stratification,Less slag ball (4 times centrifugal slag removal),Bulk density adjusted flexibly according to use,High strength (with reinforced fiber),Good elasticity, good machinability.Ceramic fiber gasket not only can withstand high temperature (1260°C) but also has very low thermal conductivity. It is an ideal insulating material.Suitable for heat insulation, sealing, electrical insulation, sound absorption, filtering and so on under high temperature environment.
