几种填料的物理特性及其在造纸中的应用比较

摘要

In this paper, the density, refractive index, surface area, particle size and its distribution of PCC, GCC, barium sulfate, titanium dioxide and talcum powder which were used as filler in lighter weight papers were tested. The optical properties and print through of the paper as well as the filler retention were compared.%对造纸填料PCC、GCC、硫酸钡、TiO2、滑石粉的密度、折射率、比表面积、粒径与分布进行了分析测定，并将它们用于抄造较低定量的纸中，比较了填料在纸中的留着情况、纸张的光学性能和印刷透印值。
