对落叶松的化学成分和预水解硫酸盐法制浆特性进行研究。结果表明,通过水预水解可以脱出原料中60.09%的聚戊糖,采用预水解未经洗涤硫酸盐蒸煮工艺能够生产出较优良的浆料。
The chemical composition of larch and pre-hydrolysis kraft pulping characteristics were studied. The results showed that 60.09% of pentosan in the feedstock could be extracted by pre-hydrolysis of water, and the better slurry could be produced by the prehydrolysis of unwashed kraft.
