摘要
研究了添加聚分子电解质—聚丙烯酸(PAA)、丹于酸(Tannic Acid)对α-Al_2O_3料浆的稳定性。结果表明,料浆的稳定性受到聚分子电解质的浓度、料浆的pH值、颗粒的粒度分布的影响,找到了分散剂适宜的使用条件。
The stability of α-Al_2O_3 suspensions with addition of polyelectrolyte-polyacrylic acid (PAA) and tannic acid was studied. The experimental results showed that the suspension stability was affected by the concentration of polyelectrolyte, pH value and size distribution of particles, and a suitable working condition of dispersant was also found.
