【摘要】 本文对红麻皮、龙须草原料的化学组成和不同制浆条件蒸煮纸浆黑液的物化性能进行了分析，红麻皮纸浆黑液含硅量低，粘度低，纸浆黑液能满足碱回收要求，而龙须草纸浆黑液含硅量与粘度均较高，需进行适当处理。更多还原

【Abstract】 Chemical compositions of bast of kenaf and chinese alpine rush,physical-chemical properties of the soda-AQ black liquor from those raw materials were determined respectively.The characteristics of the black liquor from bast of kenaf, particularly its low silica content and viscosity indicated that the black liquor could meet the requirements of chemical recovery,and those from chinese alpine rush were not good engough for chemical recovery.更多还原
