【摘要】 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 ,对磨浆过程中浆料物理强度和光学性能的变化也进行了研究更多还原

【Abstract】 The influence factors in P RC APMP process with single stage pretreatment of triploid of populus tomentosa were investigated in this paper. The results showed that the charges of NaOH and H 2O 2 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.更多还原
