针对商品漂白桉木硫酸盐浆生产过程中出现的一系列树脂障碍问题,先利用X射线荧光光谱仪等分析手段,确定桉木树脂障碍的性质和原因。然后在实际生产过程中,通过严格备料、筛选、漂白工段的工艺控制,结合添加超细滑石粉、磷酸三钠螯合剂等辅助措施,控制生产过程的树脂障碍发生。商品浆板的尘埃度明显降低,工艺流程中树脂沉积现象大大减少,取得了较好的效果。 Aiming at a series of resin obstacle problems in the process of commercial bleaching eucalyptus kraft pulp, the properties and causes of eucalyptus resin obstacle were determined by X-ray fluorescence spectrometer and other analytical methods. Then in the actual production process, through strict preparation, screening, bleaching process control, combined with adding superfine talc, trisodium phosphate chelating agents and other auxiliary measures to control the production process of resin barriers. The pulp of the product significantly reduce the dust, the process of resin deposition greatly reduced the phenomenon, and achieved good results.
