摘　　要：鉴于白泥纤维脆性大,且难于分散,成纸强度低的问题,利用实验室自制软化剂对其进行软化。通过扫描电镜分析其软化效果,并通过白泥纤维/植物纤维复合纸性能测试,探讨了软化改性前后的白泥纤维对纸张性能的影响,同时研究了不同浓度的CPAM及CMC对白泥纤维的分散以及对白泥纤维/植物纤维复合纸强度的影响。结果表明,CPAM分散效果优于CMC,但是分散时间比CMC长。综合考虑分散效果及复合纸强度,选择0.4%的CMC作为纤维最佳分散条件,此条件下,添加30%的白泥纤维,所抄纸张的环压指数比0.4%CPAM分散条件下所抄的纸张提高64%,抗张指数提高110%。In view of the britghtness and being hard in dispersion of white mud fiber, and being low in paper strength, the self - made softener was used to soften it. The changes of the form of fiber surface were observed by the scanning electron microscopy （SEM）. Effects of modified and unmodified white mud fiber on paper properties were investigated through the white mud fiber/plant fiber composite paper test. Influences of adding ditferent con- centration of CPAM and CMC on dispersing of white mud fiber and the strength of composite paper were studied. The results show that, dispersion effect added CPAM is better than that of CMC, but the dispersion time added CPAM is longer than that of CMC. Comprehensive consideration of the dispersion effect and composite paper strength, the optimal dispersion condition of CMC is 0. 4% , under this condition the ring crush index and tensile index increase by 64% and 110% when the white mud fiber filling is 30%.
