摘　　要：本实验主要研究石膏晶须在造纸中的留着,并与碳酸钙进行了对比。石膏晶须助留助滤的最优方案应采用CS、CPAM、CP3助留助滤体系,其使用量分别为1.5%、0.04%、0.02%,此时填料留着率为53.67%,其滤水时间适中,为79.3s。能在有效提高填料留着率的同时,降低滤水时间,保证良好的助留助滤效果。In this paper, we focused on retention effect of gypsum whisker in papermaking, and compared the effect with calcium carbonate. The optimal solution of gypsum whisker retention and drainage system should use CS, CPAM, CP3. The optimal dosage was： CS 1.5% , CPAM 0. 04% , CP3 0. 02%. With this condition, the retention of filler was 53.67%, the draining time was 79.3s. This system could effectively improve the retention of filler while reducing draining time and ensure good retention and drainage effect.
