三倍体毛白杨单段预处理P-RC APMP制浆的研究

Study on Poplar P-RC APMP with Single Pretreatment

对速生优质树种三倍体毛白杨进行了单段预处理的P RCAPMP制浆 ,通过对各影响因素的研究发现 ,在化学预处理中 ,NaOH和H2 O2 用量是影响纸浆性能的主要因素 ,一段磨浆后的高浓停留段能在较大程度上改善浆的质量。此外 。

The influence factors in P-RC APMP process with single stage pretreatment of triploid of populus tomentosa were investigated. The results show that the charges of NaOH and H2O2 are the main factor affecting the quality of the resultant pulp, the retention of pulp in high consistency stage after first refining stage can improve the quality of the pulp significantly, especially can upgrade the brightness of the pulp. In addition, the variation of optical and physical properties during the refining process was also studied.
