摘　　要：面对禁废令实施后,箱纸板行业日益缺少优质纤维原料的行业痛点问题,以食品加工废弃物槟榔果壳作为原料,系统性分析其作为纤维原料的应用潜力。当选择用烧碱法制浆(用碱量18%,N a2O计),保温1.5 h时,浆料得率都在40%以上,细浆得率最高达87.9%。电子显微镜观察到槟榔果壳在煮浆后杂细胞变少,纤维表面粗糙度增加;当槟榔果壳浆质量占比10%时,得到的包装纸强度最大:耐破指数1.97 k P a.m^(2)/g、抗张指数34.21 N.m/g、撕裂指数6.5 m N.m^(2)/g、耐折度12次,且实验数据表明槟榔果壳浆占比在20%以内时,配抄纸张物理性能均满足国家箱纸板标准。In the face of the shortage of high-quality fiber materials after the implementation of the waste paper import ban,the paper systematically analyzed the application potential of food processing waste betel nut shell as raw material.When using caustic soda pulping(18%alkali content,Na2O)and holding for 1.5h,the yield of pulp is above 40%,and the yield of fine pulp is up to 87.9%.It was observed by electron microscope that the impurity cells became less and the surface roughness of fiber increased after the pulping.When betel nut shell pulp accounted for 10%,the paper strength reached the maximum.When the breaking index is 1.97 kPa·m^(2)∙g^(-1),the tensile index is 34.21 N·m∙g^(-1),the tearing index is 6.5 mN·m^(2)∙g^(-1),and the bending resistance is 12 times.The experimental data show that when the ratio of betel nut shell pulp is less than 20%,the physical properties of the laminated paper meet the national standard for containerboard.
