对煅烧的片麻岩云母采用不同的机械开片方式处理后,与伟晶岩云母鳞片混合制得复合云母纸,研究不同开片方式对片麻岩复合云母纸拉伸强度的影响.结果表明:研磨方式更适合于片麻岩云母的开片处理,当研磨开片处理时间为15 min,片麻岩云母掺加量为9%时,复合云母纸的拉伸强度达到最大值4.8 N/cm.
A composite mica paper was prepared by mixing calcined gneiss mica treated by different me-chanical delamination method and pegmatite mica, and the effects of different treatments of gneiss mica on the tensile strength of the composite mica paper were studied. The results show that the grinding treat-ment is more suitable for the delamination of gneiss mica. When the grinding time is 15 min, the gneiss mica content is 9% , the tensile strength of the composite mica paper attains its maximum value 4.8 N/cm.
