| 摘 要： | 为了获得性能指标符合消光剂要求的二氧化硅产品,通过正交实验L16(45)对沉淀法合成二氧化硅的过程进行优化,研究各因素对二氧化硅中位径、吸油值的影响规律,利用X射线衍射、扫描电镜对二氧化硅粒子的结构、形貌进行表征。结果表明,制备的二氧化硅为无定形产物,颗粒呈球形,一次颗粒粒径约为30 nm,各项指标与进口产品相近。

| Abstract: | In order to prepare silica powders using as fumed matting agent,the direct precipitation method was adopted to prepare silica by the orthogonal experimental program(L16(45)).The influences of different factors on average diameter,oil-absorbed value of silica powders were investigated.The structure and morphology were characterized by X ray diffraction(XRD),scanning electron microscope(SEM).The results show that the silica particles are uniform global,and the average diameter of original particles is about 30 nm.The performance index of silica is equal to the import products. |
