摘要
结合国内造纸企业碱回收白泥的回用情况来探讨白泥性能、品质提升及生产技术,结果表明,碱回收白泥质量和商品轻钙相比存在一定差异,但可以部分甚至全部替代商品轻钙作文化用纸填料;生产控制需要继续加强,以优化白泥的晶型、粒径分布和白度,提高其应用性能。
In this paper, properties of white lime sludge, qual- ity improvement and production technology were discussed, by combining the using conditions of white lime sludge of domestic paper enterprises. Results showed that there is some difference between white lime sludge from alkali recovery and commercial PCC, but it can be used as filler of offset printing paper alone or combining with commercial PCC. Production control should be reinforced to acquire better quality such as particle crystal, particle size distribution and brightness so as to improve its application performance.
