【摘要】 研究了在桉木化机浆中聚合氯化铝（ＰＡＣ）作施胶沉淀剂的阴离子分散松香胶中性施胶的影响，淀粉、阳离子聚丙烯酰胺（ＣＰＡＭ）对中性施胶效果的作用以及ｐＨ值对以硫酸铝或ＰＡＣ作施胶沉淀剂进行施胶的影响。根据实验结果得出适宜的中性施胶工艺条件，淀粉和ＣＰＡＭ都具有较好的助施胶效果。ＣＰＡＭ分子量越大施胶效果越好。ｐＨ值为７．０时，明矾－阴离子分散松香胶（ＤＲ）施胶系统的施胶度已很小，而 ＰＡＣ－ＡＤＲ系统仍保持较高的施胶度。更多还原

【Abstract】 The application of PAC in neutral sizing of anionic dispersive rosin size, the effect of pH value, CPAM and PAE on neutral sizing, and the difference of aluminum sulfate and PAC in neutral sizing were studied. The result indicated that there is the best addition dose which can acquire better sizing effects for PAC, starch, CPAM, PAE. But the addition of filler cause decreasing in sizing degree. The larger the molecular weight of CPAM, the better the sizing effect. When pH is 7. 0 the sizing degree of aluminum sulfate-ADR sizing systems were much small, however, PAC-ADR systems still have a high degree of sizing.更多还原
