木素脱除

Cotton linter pulp was made using oxygen-alkali cooking enhanced by hydrogen peroxide following the pretreatment to remove the impurity; microcrystalline cellulose was obtained through acid hydrolysis of cotton liter pulp.

通过对棉短绒进行预处理除杂，采用过氧化氢强化的氧碱蒸煮脱除棉短绒中少量的脂类物质和棉籽壳引入的木素，然后通过酸水解制备微晶纤维素。

In order to evaluate the capability of lignin degradation and pitch elimination from Masson pine chips by nature white-rot fungi, 20 white-rot fungus strains were obtained by petri dishes screening and petri dishes color-reaction screening. One G strain with the lowest Mycel/Col value was then inoculated onto the surface of Masson pine chip, and the degradation rates of lignin and pitch were measured after 3, 5, 7, 9 days, respectively.

为评价从野外筛选得到的白腐菌对造纸原料马尾松的木素降解和树脂脱除能力，将带菌样本经室内平板初筛及平板变色反应复筛，得到了20株纯白腐菌菌株，并对变色系数最小的一株菌株G进行松木片固体接种试验，测定3、5、7、9天后松木片的木素、树脂降解情况。

In this paper, chemistry composition, fiber morphology and pulping property in Solidago canadensis were analyzed and determined preliminarily. The results showed that the content of holocellulose was 81.86%, the content of cellulose was 42.63%, the content of lignin was 18.86%, it is feasible for using Solidago canadensis pulping based on it's chemical composition. The ratio of fiber length to width in Solidago canadensis was 36.67, the average length of fiber was 440 μm, and the length of fiber was too short to pulping. The ratio of wall thickness of fiber cell to lumen diameter was 0.34, and it was smaller than that of other woody fiber. In this experiment, four different methods of pulping were as follows: kraft-AQ pulping Ⅰ, kraft-AQ pulping Ⅱ, alkaline pulping, alkaline sulfite adding AQ pulping, but it was difficult for lignin removal in Solidago canadensis.

通过对一枝黄花的化学组成、纤维形态以及制浆性能进行初步探索，结果表明：(1)加拿大一枝黄花的综纤维素含量为81.86%，硝酸乙醇纤维素含量42.63%，木素含量18.86%，由化学组成看，加拿大一枝黄花是比较适宜制浆造纸的；(2)加拿大一枝黄花纤维的长宽比为36.67，纤维平均长度为44μm，从纤维长度来看，加拿大一枝黄花的纤维较短，不适宜制浆，其纤维壁腔比0.34，和其它速生材相比较小；(3)采用4种碱法制浆方案，硫酸盐蒽醌法Ⅰ，硫酸盐蒽醌法Ⅱ、烧碱法、碱性亚钠＋蒽醌法，结果显示，加拿大一枝黄花的木素非常难脱除。

The results showed that: The lignin riddance processing with microwave auxiliary was very quick and efficient. And the effect to the hardwood Fraxinus mandshurica samples is better than that to the softwood Larix gmelini.

结果表明，微波辅助法在阔叶材水曲柳和针叶材落叶松的木素脱除方面表现出快速、高效，且对于水曲柳的效果好于落叶松。

The electrochemically mediated bleaching of aspen kraft pulp with violuric acid as the mediator was investigated in this paper.

结果表明，采用钌钛涂层电极为阳极，不锈钢为阴极，以紫脲酸为介体对杨木硫酸盐浆进行无隔膜电化学处理，能有效脱除纸浆中的残余木素，而浆的黏度损失较小。
