摘要
首先简要介绍了分散剂的作用机理及其在铁氧体制备过程中所起的的助磨、稳定分散、稀释减水降低能耗等作用。选择四种不同的分散剂进行实验,固定分散剂的加入量1%,比较了它们的分散效果,发现不同的分散剂分散效果各异。以分散效果较好的分散剂A为例,进一步考察其加入量对料浆分散效果的影响。表明分散剂有一个最佳加入量,低于或高于最佳量,都不能得到较好的分散效果。因此,对不同工艺、不同成分的粉料,应通过试验确定适宜的分散剂及其用量。
Dispersion mechanisms of different dispersants were introduced briefly, and the aid-grinding, stable dsipersing, diluting and water reducing, and energy consumption reducing effects of the dispersant during the preparation of the ferrite were also discussed. The dispersive effect of four kins of dispersants in the ferrite slurry were investigated with a fixed content of 1% for the dispersants. The results showed that the dispersive effect of different dispersants is different. For the dispersant A with a better dispersive effect, the effect of its content on the dispersion was further investigated. The results indicated that an optinal amount of dispersant exists. Therefore, the proper dispersant and its content used for dispersing the ferrite slurry with different composition and prepared by different process should be determined by experiments.
