讨论了影响印刷纸针叶木硫酸盐浆(SW K)用量的因素,提出几种在一定情况下可减少SW K用量的方法。尽管SC-A和LW C的生产工艺(例如:涂布和加填)和纸页结构不同,但其强度和纸幅运行性基本相同,且一般都使用SW K。由于LW C和SC-A都要求纸页表面平整、稳定、纸页结构“紧密”(对油墨 The influencing factors on the amount of kraft pulp (SW K) used in printing paper were discussed. Several methods to reduce the amount of SW K in some cases were proposed. Although SC-A and LW C have different manufacturing processes (for example, coating and filling) and sheet structures, their strength and web runnability are basically the same, and SW K is generally used. Since both LW C and SC-A require that the surface of the sheet be smooth and stable, the sheet structure is “tight”
