| 摘 要： | 研究聚合物等高粘度液体中矿物填料的沉降性能,可以为新型绝缘灌注胶以及矿物材料研究与应用提供科学依据,根据斯托克斯公式和离心沉降速度公式以及高速旋转离心实验特点,时自然沉降时间计算公式进行推导.并根据绝缘灌注胶特点以及不同粒度微晶白云母在环氧树脂中高速离心沉降实验,总结出一种能够对聚合物等高粘度液体中矿物填料的沉降性能进行快速定量表征的离心分层距离法;实验结果表明:微晶白云母在E-51环氧树脂中的沉降速度和分层比例都分别与其粒度大小呈正比关系,1 000目完全沉降(分层比例100%)需要7 068.7 d,其自然沉降速度为0.7×10-7mm·s-1,若要保持3个月内不发生明显的分层现象,应当采用1 000目或更细小的粒度.
