摘　　要：对杨木BCTMP替代阔叶木KP生产LWC纸进行研究，分析了不同BCTMP替代率对原纸和涂布纸质量的影响。结果表明，随着替代率的提高，配抄纸张的抗张强度有所增加，其他机械强度没有显著变化；原纸粗糙度略有增加，但对涂料覆盖率没有显著影响；原纸孔隙度增加，但并不改变空隙的平均尺寸；涂布纸的表面粗糙度和光泽度略有降低，该影响可以通过适当增大软压光压力来补偿。Substituting BCTMP for chemical pulps, such as bleached hardwood kraft pulp in many paper grades is in rising demand for reducing cost and improving proudct performance. In this paper we investigated the effect of substituting aspen BCTMP for hardwood kraft pulp （varying from 10% to 30% ） on product performance of light weight coated paper. The results showed that the tensile index increases and other strength properties are essentially unchanged as the substitution level increases. The surface roughness of the base paper increases slightly with the BCTMP substitution level, while coating coverage of the base paper is not affected significantly. The increased BCTMP substitution results in an increase in and, an increase in surface roughness of the coated paper, however the latter can be compensated by a higher nip-load calendaring.
