摘要
研究了BCTMP的物理化学特性及其对ASA中性施胶的影响。研究结果表明:BCTMP含有较多的细小组分,这些细小组分的比表面积较大且负电荷密度较高,对ASA的施胶不利;加入适量的阳离子助剂有利于获得较好的施胶效果;适当硬度的抄纸用水也有利于BCTMP的ASA施胶。
In this paper, the physical-chemical characteristics of BCTMP and its effect on neutral sizing with ASA were studied. The findings show that BCTMP contains much content of fine components, which have much larger specific surface and carry more negative charges than that of fine-free BCTMP, being unfavorable to ASA sizing and that proper doses of positive additives could improve siz- ing effect of BCTMP with ASA and the water with proper hardness is also favorable to ASA sizing of BCTMP.
