摘要
用羧甲基纤维素和氧化铈混合,经聚甲基丙烯酸苏达水、分散剂、硫酸处理悬浮聚合制备了氧化铈复合磨粒,与未经处理的氧化铈磨粒进行性能比较;并分析了分散剂种类、分散剂用量和搅拌速度对粒径的影响。结果表明,复合粒子球型磨粒具有分散流动性能好的特点,适用于抛光磨具生产。
Compound cerium oxide grains are prepared by suspension polymerization technique. Characteristics tests are made in terms of their dispersity, lyophilic ability, mobility and adhesion. Influence of the dispersing agent, its amount and concentration as well as the blending speed upon the diameter of the compound cerium grains is analysed. Compared to conventional cerium grains, the compound ones feature excellent dispersity and mobility, suitable for use as polishing abrasive grains.
