大麻全杆化机浆H_2O_2漂白

On Bleaching of Hemp Stalk Chemico-mechanical Pulp with H_2O_2

大麻全杆化机浆经Ｈ２Ｏ２单段漂白后，其白度和物理强度明显增加，达到二号凸版纸标准，漂白纤维变得更柔软，纤维表面变得更整洁，主要发色基因双键和共轭羰基被破坏，芳族邻羟基酮和聚木糖Ｃ＝０键及甲氧基等被消除．

After the chemico-mechanical pulp of the whole hemp stalk was bleached with H2O2,its brightness and strength increase remarkably and come up to the standard of No. 2 letterpress paper,its fibers change softer,the surface of its fibers becomes more smooth,its main colour base-double bonds and conjugate carbonyl are damaged,aromatic hydroxyl ketone and poly-xylose bond C= 0 and methoxy groups are removed.
