中文摘要：

将玉米秸皮经过生物预处理后磨制化学机械浆,并与秸穰混合抄制瓦楞原纸。制得的秸皮化机浆粗浆得率为85.7%、白度为27.1%,经漂白后浆料得率为82.1%、白度为71.2%,打浆后各项强度性能指标都较为优良。改性秸穰的加入进一步改善秸皮浆性能,漂白浆返黄值有所下降,当秸穰含量为20%时,漂白浆的抗张指数和耐破指数达到最大值,分别增加了27.8%和17.4%;秸穰含量为30%时,未漂浆的抗张指数和耐破指数分别增加了96.8%和83.3%。同时,两种浆的耐折度也有显著改善。

英文摘要：

The experiment of chemi-mechamical pulping of leaf-free corn stalks with bio-pretreatment by using the fungi was carried out the brightness of the unbleached pulp was 27.1%ISO and the unscreened pulp yield was 85.7%,the brightness reached 71.2%ISO after bleaching.The bleached pulp proved quite good strength performance.Pulp strength was improved further when some modified pith of corn stalk was added,colour reversion value of the pulp declined slightly.Tensile strength and burst strength of the bleached pulp increased 27.75% and 17.39% respectively compared with the control pulp when the dosage of the modified pith of corn stalks was 20% in similarly the tensile strength and burst strength of the bleached pulp increased by 96.76% and 83.33% respectively when the content of the pith of corn stalks in pulp was 30%.In addition,the folding endurance of the paper was also improved sharply.Finally the manufacture of corrugating medium with corn stalks as raw material,and the adhesion mechanism of modified pith of corn stalks.
