用碱性脂肪酶消除磨木浆的树脂障碍的探索

Reducing Troublesome Pitch by Using Alkaline Lipase

用碱性脂肪酶对磨木浆及其沉积树脂进行水解和树脂沉积试验 .结果表明 :碱性脂肪酶能够消除树脂沉积 .加酶水解产物为较低粘性的组分 .加酶处理不会影响纸浆和纸的质量 .

Reported that the test of enzyme hydrolysis and pitch deposition of ground pulp and its deposit by using alkaline lipase.The results showed that ground pulp and its deposit suspension was treated with alkaline lipase to reduce pitch deposition; the hydrolysates were less sticky components;the pulp was treated with alkaline lipase not to exert an influence on quality of the pulp and the paper.
