| 摘 要： | 利用热重分析方法对铁氧体料浆中颗粒表面聚乙烯醇（ＰＶＡ）吸附情况进行了研究。结果表明，颗粒表面ＰＶＡ吸附厚度与颗粒尺寸大小、料浆中ＰＶＡ百分含量、料浆温度等有关，这种特性将影响ＰＶＡ在料浆中的分布。文中给出了颗粒表面ＰＶＡ吸附层厚度理论计算和实验测量方法。

Calculation and Determination of the Thickness of PVA Adsorbed Layer on Ferrite Particles |
| |
| Abstract: | The properties of PVA adsorbed layer on ferrite particles in slurry werestudied by thermogravimetric analysis. It is shown that the thickness of PVA adsorded layer on ferrite particles depends on the ferrite particle size, PVA content in slurry and slurry temperature,which affect the distribution of PVA in slurry. The theoretical calculation and the testing method of PVA adsorbed layer were given is this paper. |
