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。
The effect of beating on the strength properties of the paper and wollastonite retention was studied when the wood was filled with wollastonite. The results showed that the beating of wood pulp with wollastonite paper has some improvement effect, softwood pulp and hardwood pulp beating degrees were 48 ~ 52 ° SR and 44 ~ 48 ° SR, plus wollastonite into paper strength The wastage of softwood pulp and hardwood pulp was respectively 52 ° SR and 48 ° SR, wollastonite was the best. Wollastonite retention in wood pulp is higher, much higher than other conventional papermaking filler.
