【摘要】 本文对三倍体毛白杨低硬度化学浆氧脱木素和强化氧脱木素进行了研究, 通过实验分析了用碱量、温度、时间、氧压等对三倍体毛白杨低硬度氢氧化钠蒽醌浆氧脱木素和强化氧脱木素后的卡伯值、粘度、白度以及木素的脱除情况等的影响,确定了该浆种氧脱木素和强化氧脱木素较适宜的工艺条件。更多还原

【Abstract】 Oxygen delignification and strengthened oxygen delignification of triploid of populus tomentosa of Soda-AQ pulp with lower kappa is studied. Those influential factors which are different NaOH dosage, temperature, oxygen pressure and time etc. were analyzed by the varieties of kappa number, viscosity, delignification conditions and pulp brightness during the oxygen delignification and strengthened oxygen delignification course. And the better process conditions of oxygen delignification and strengthened oxygen delignification was confirmed by the experiment.更多还原
