摘要
本文研究了小叶桉P-RC APMP制浆中,不同二段磨浆浓度对制浆性能的影响。研究结果表明:相同的化学浸渍条件下,第一段采用常规的高浓常压磨浆,经高浓停留完成漂白反应后,二段采用高浓或低浓磨浆各有优劣。采用较高浓度进行二段磨浆,磨至相近加拿大游离度时,制得纸浆的强度性能和白度较低浓磨浆的高,浆中的细小组分含量较低浓磨浆的低,但纸浆的纤维束含量较低浓磨浆的高。
Eucalyptus exserta woodchips were pulped by using the typical P-RC APMP process,and the influences on pulping properties by varying consistency at the second refining stage were investigated.The results showed that,after the first refining stage,pulps refined with high consistency at the second refining stage to a similar Canadian Standard Freeness level,the strength properties and brightness were higher,and fines were lower,and shives content was higher than that of pulps refined at low consistency.
