摘要
研究了溶解和胶体物质(DCS)对造纸湿部化学的影响。结果表明,DCS的加入能够降低单元助留助滤体系阳离子聚丙烯酰胺(CPAM)、双元助留助滤体系聚二甲基二烯丙基氯化铵(PDADMAC)/CPAM和微粒助留助滤体系CPAM/膨润土的助留助滤效果,并且能够使得不同助留助滤体系存在下的杨木P-RC APMP的Zeta电位下降。DCS的加入降低了阳离子助剂对滑石粉的絮聚程度,但随着DCS加入量的增加,阳离子助剂对碳酸钙的絮聚程度先下降后增加。同时,DCS的加入使得不同施胶剂的施胶效果变差。PDADMAC作为施胶促进剂对不同施胶剂或者含有不同DCS的浆料有一个最佳用量。
The wet-end chemistry will be disturbed by DCS.The experimental results indicated that the addition of DCS decreases the efficiency of single-polymer CPAM,dual-polymer PDADMAC/CPAM and microparticle CPAM/bentonite retention and drainage aid system.DCS can reduce the zeta potential of aspen P-RC APMP containing retention and drainage aids.The flocculation degree of talc powder by cationic aids can be decreased by the addition of DCS.However,the flocculation degree of calcium carbonate decreases at the initial stage and then increases with the increase volume of DCS addition.Finally,the sizing efficiency of rosin size and alkylketone dimer is dramatically decreased when the DCS is added to the pulp.
