探讨用微细纤维和填料PCC(沉淀碳酸钙)替代部分纤维后文化用纸的结构和性能的变化。这种新配方可使文化用纸中PCC的加入量提高至50%～60%。与传统高填文化用纸相比,新配方纸可具有更高的强度性能和光学性能。
The paper discusses the change of the structure and properties of the paper after replacing some fibers with the fine fibers and the filler PCC (precipitated calcium carbonate). This new formula will increase the amount of PCC in cultural paper to 50% to 60%. Compared with the traditional high-filled paper, the new formula paper can have higher strength and optical properties.
