摘　　要：研究了木浆加填硅灰石造纸时,打浆对于成纸强度性能以及硅灰石留着情况的影响。结果表明,打浆对木浆加填硅灰石造纸具有一定改善效果,针叶木浆与阔叶木浆打浆度分别为48～52°SR和44～48°SR时,加填硅灰石成纸的强度最大;针叶木浆与阔叶木浆打浆度分别为52°SR和48°SR时,硅灰石留着情况最佳。硅灰石在木浆中的留着率较高,远高于其他常规造纸填料。This article discusses the influence of beating pulp on paper strength and retention of wollastonite when wollastonite used in wood pulp. The results shows that effect of wollastonite used in wood pulp improvement by beating pulp, paper strength is maximum when the beating degree of softwood pulp is 48-52°SR and beating degree of hardwood pulp is 44-48°SR, the retention of wollastonite is optimum when the beating degree of softwood pulp is 52°SR and beating degree of hardwood pulp is 48°SR. The retention of wollastonite is much higher than other conventional filler used in papermaking.
