粗渣

改良硫酸盐浆比常规硫酸盐浆的得率高，而且粗渣率低。

Modified kraft pulp has higher yield and lower rejects than its corresponding conventional kraft pulp .

结果表明在混合阔叶木和桦木的碱法蒸煮中添加少量的绿氧助剂可以提高细浆得率，改善蒸煮的均匀性，减少粗渣量，同时对成浆白度也有所提高。

The results indicated that adding a small amount of green oxygen in the hardwood alkaline pulping increased the fine pulp yield , improved the uniformity of cooking , reduced the amount of dregs and enhanced the pulp brightness .
