摘要

本文介绍了在有聚乙二醇（PEG）和抗静电成分存在的情况下细磨 αAl2O3 的过程的研究结果。结果表明，细颗粒团聚的主要原因是表面静电荷的影响。引入 PEG 可防止出现 "伪粘性研磨介质"，消除新形成的超细颗粒表面多余的静电荷，同时还可强化原生阿尔法氧化铝晶体的磨损过程。抗静电组合物成功地中和了表面电荷，但没有表现出研磨强化效果。

Research in the Area of Preparing Activated Alumina. Part 5. Different Technological Approaches to the Process of Fine Milling of High-Alumina Raw Materials

Results of studying the process of fine milling of α-Al₂O₃ in the presence of polyethylene glycol (PEG) and an antistatic composition are presented. It is shown that the main reason for agglomeration of fine particles is the effect of appearance of an electrostatic surface charge. Introduction of PEG prevents appearance of a “pseudo-viscous milling medium”, removing the excess electrostatic charge at the surface of newly formed ultrafine particles, and also intensifies the wear process of primary alpha-alumina crystals. The antistatic composition successfully neutralizes a surface electrical charge, but does not exhibit a milling intensifier effect.
