摘　　要：进行了 4种人工种植桉木改良硫酸盐 (深度脱木素 )法制浆的实验 .结果表明 ,改良硫酸盐法制浆的选择性明显高于常规硫酸盐蒸煮法 ,改良硫酸盐法制浆可以生产出卡伯值非常低且强度很好的纸浆 .与常规硫酸盐蒸煮相比 ,改良硫酸盐蒸煮桉木浆的卡伯值低 5～ 6个单位 ,而纸浆粘度却高出 2 .8mPa·s.改良硫酸盐浆比常规硫酸盐浆的得率高 ,而且粗渣率低 .但是由于反应速度慢 。Four Modified kraft (extended delignification) pulpings of plantation eucalyptus wood were carried out in laboratory. The results demonstrate that modified kraft pulping has higher pulping selectivity than conventional kraft pulping. Modified kraft pulping can produce very low Kappa number pulp with good pulp strength. Compared with the conventional kraft pulp, the Kappa number of modified kraft pulp of eucalyptus wood is 5～6 units lower, but its viscosity is more than 2.8 mPa·s higher. Modified kraft pulp has higher yield and lower rejects than its corresponding conventional kraft pulp. However, due to the slow reaction, modified kraft pulping needs greater H_factor value than conventional kraft pulping to achieve a given Kappa number.
