摘　　要：白云纸业的潘迪亚式横管连续蒸煮器系统的主要原料是杨木板皮和桉木板皮。为了缓解原料收购困难,经过多次实验与中试,尝试添加松木板皮作为制浆原料。松木∶杨木按照30∶70添加使用,采用单独蒸煮,混合漂白的工艺。配用松木板皮作原料的中试过程中遇到了洗浆机运行中浆层掉网问题,经调整洗浆机问题得以解决。由于添加的松木板皮系针叶木材原料,自制浆品质得以改善。抄纸工段68g/m2双胶纸品种的生产中,减少了商品针叶木浆配比9%,使得吨纸综合成本降低44.8元。Normally,poplar and eucalyptus veneer are used as pulping raw materials for the Pandia chemipulper in Baiyun Paper.However,in order to alleviate the difficulty of wood chip acquisition and broaden materials supply,Baiyun Paper,after experiments and pilot tests,attempted to add pine veneer as pulping raw material.Pine and poplar were added in a ratio of 30:70,and the process of separate cooking and mixed bleaching was adopted.The results showed that the quality of pulping was greatly improved.In addition,the original system encountered the problem of pulp layer falling off the screen during the operation of the pulp washer,which was solved by adjusting the pulp washer later.Since the added pine veneer is a softwood material,the pulping quality has been improved.The proportion of 68g/m2 offset paper softwood pulp in the papermaking decreased by 9%,and the comprehensive cost per ton of paper pulp decreased by 44.8 yuan.The addition and use of pine veneer not only broadens the variety of wood chip,but also improves the strength performance of pulp,laying a good foundation for enterprise transformation and paper processing.
