摘　　要：研究了在阔叶木浆纤维的细胞内原位沉积硅酸钙的工艺条件及其可行性。结果表明,利用原位沉积合成方法在纸浆纤维细胞内实现填充是可行的,最佳加填工艺条件:预浸时间30min,反应时间20min,反应温度60℃,药品浓度1.25 mol/L,CPAM用量2.5%。通过对加填后纤维的SEM观察,发现硅酸钙在纤维细胞内有沉积。并与传统加填方式进行了比较,显示出细胞内加填技术的优越性。The feasibility and process conditions of in-situ synthesis of calcium silicate in the cell of the hard wood pulp fibers were investigated.The results indicated that fiber loading technology using in-situ deposition of calcium silicate in the pulp fibers is feasible.Under best experimental conditions calcium silicate was loaded.The concentration of chemicals was 1.25mol/L,the reaction temperature and the presoak time and the reaction time were 60℃,30 min and 20 min respectively,and the dosage of CPAM was 2.5%.The deposition of calcium silicate in the cell of the pulp fibers is found by SEM observation.And comparison with the traditional loading,the excellence of fiber loading is showed.
