以自制的水溶性阳离子铝锆偶联剂对轻质碳酸钙进行了表面改性,比较了改性前后轻质碳酸钙的Zeta电位、润湿性、粘度、比表面积、沉降高度、扫描电镜图像以及在水中分散情况的变化,结果表明改性后轻质碳酸钙的表面性能得到改善,将此改性轻质碳酸钙作为填料抄纸发现,改性后轻质碳酸钙在纸页中的留着率大大提高,同时纸张抗张强度、耐破度、撕裂度等也得到提高.
以自製的水溶性暘離子鋁鋯偶聯劑對輕質碳痠鈣進行瞭錶麵改性,比較瞭改性前後輕質碳痠鈣的Zeta電位、潤濕性、粘度、比錶麵積、沉降高度、掃描電鏡圖像以及在水中分散情況的變化,結果錶明改性後輕質碳痠鈣的錶麵性能得到改善,將此改性輕質碳痠鈣作為填料抄紙髮現,改性後輕質碳痠鈣在紙頁中的留著率大大提高,同時紙張抗張彊度、耐破度、撕裂度等也得到提高.

Precipitated calcium carbonate was modified by homemade water-soluble cationic zircoaluminate coupling agents. The zata potential, the wettability, the viscidity, the surface area, the sedimentation height, the SEM image and the dispersion in water of precipitated calcium carbonate before and after modification were compared. The result indicates that the surface performance of precipitated calcium carbonate improve after modification. The modified precipitated calcium carbonate was used as filler in papermaking. The result indicates that the filler retention rate improves and the tensile strength, the burst strength and the tear strength of paper also improve too.
