纸浆

Paper pulp and mixed blowing agent (sodium bicarbonate,potassium alum,starch,potas- sium D-bitartrate,and calcium carbonate) was used to produce the foaming pulp material.

以纸浆为原料，使用复合发泡剂(碳酸氢钠、钾明矾、淀粉、酒石酸氢钾、轻质碳酸钙)，制作纸浆发泡缓冲材料，得到稳定的实验配方，所得发泡材料的静态缓冲系数在4～5之间。

Can also be set up in high concentration hydraulic pulper, from the high concentration of water in the pulper out of waste pulp for coarse screening to remove large, heavy debris to reduce the flow back of the burden of screening equipment, large-scale paper machine And high output device of choice.

用于对废纸浆进行粗大杂质的筛选，可设置于高浓水力碎浆机之后，对从高浓水力碎浆机中出来的废纸浆进行粗筛选，除去大、重、杂物，减轻后面流程中筛选设备的负担，是大型纸机，高产量的首选设备。

Its work is the process of spraying by the pulp put out the warehouse I expected or high water concentration pulper, as well as the initial concentration of the pulp slurry into the mouth of the double helix squeeze machine feed the population through the right and left of the screw shaft Reverse spin, by the end of the pulp to be on the other side.

其工作过程是纸浆由喷放仓的出料口或高浓水力碎浆机的以及经初步浓缩的浆料出浆口进入该双螺旋挤浆机的进料口，通过左、右螺旋轴的反向旋转，纸浆由一端被推向另一端。

Until very recently, the two largest pulp manufacturing groups on Sumatra used timber from natural tropical forest as the primary source of their pulpwood.

直到最近，苏门答腊岛上两个最大的纸浆生产集团还在采用天然的热带森林木材作为他们纸浆的主要来源。

However, because of the low value of pulpwood, it is normally harvested only if the logging operation is fairly close to a paper plant.

然而，由于纸浆的低价格，通常只有采伐作业临近纸浆用材时才会顺便一起采伐。

Based on the technical maturity with an emphatieal considering economic maturing and on approprite considering of guantitative maturity, it determined the felling age of masson pine pulpwood on different site index and different grow model, the best manage model on different seed provenance and different site index; the felling ages of masson pine pulpwood in Hubei Province were from 15 to 26 years old.

根据"以工艺成熟为基限，重点考虑经济成熟，适当兼顾数量成熟"的原则，确定不同立地、不同栽培模式下马尾松纸浆林的主伐年龄及不同种源、不同立地指数的最佳经营模式，提出湖北省马尾松纸浆林的主伐年龄在15～26 a之间。

During the bleaching process,there was no significant change of lignin structure unit.The carbonyl and quinoid structure had a close relati...

同时对不同纸浆在漂白过程中的变化进行了研究，对影响纸浆白度的因素进行了分析

The study concerns about the measurement of lignin in sulfite cooking liquor with visible light,and the predicting of pulp Kappa number is achieved by the measurement of dissolved lignin in sulphite cooking liquor.

本研究是用可见光分光光谱技术在线测量酸法制浆过程蒸煮液中木素的浓度，通过蒸煮液中溶出的木素含量去推算纸浆中木素含量和纸浆的卡伯值。

The grafting rate and surface charge density of the pulp increased when the amount of ceriumammonium nitrateinitiator increased from 2% to .

实验结果表明，当引发剂硝酸铈铵的用量从2%提高到8%时，纸浆的接枝率和阳离子表面电荷密度稳步提高；进一步提高引发剂的用量，纸浆的接枝率和阳离子表面电荷密度变化平坦。

To treat unbleached wheat straw pulp with xylanases can result in a decrease in chlorine usage or an increase in brightness of the pulp.

用木聚糖酶处理未漂麦草浆，纸浆的可漂性得到改善，用氯量减少或提提要：纸浆白度提高。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
