| 摘 要： | 以水玻璃和硫酸为原料,文章采用化学沉淀法制备了白炭黑料浆,然后通过烘箱干燥、微波干燥和喷雾干燥3种不同的干燥方式获得白炭黑颗粒.采用X射线衍射、扫描电子显微镜、比表面积(BET)分析、吸油值(DBP)分析等对3种不同颗粒的结构、形貌及性能进行了表征.结果表明:喷雾干燥得到的颗粒较适中,为30～50 μm；微波干燥的颗粒...

Influence of drying methods on properties of precipitated SiO_2 |
| |
| Abstract: | Precipitated SiO2 slurry was prepared by chemical precipitation,using sodium silicate and sulfuric acid as starting materials.And then oven drying,microwave drying and spray drying were used to obtain three kinds of different precipitated SiO2 particles separately.The structure,morphology and property of the precipitated SiO2 particles were characterized with X-ray diffraction,scanning electron microscopy,specific surface area analysis(BET value) and oil absorption value analysis(DBP value).The results show... |
