聚烯烃具有优良的机械性能和电气性能,在生产部门得到广泛的应用。聚烯烃在加工、储存和使用过程中将由于各种因素的影响,使其性能逐渐变坏,以致最后丧失使用价值。聚烯烃老化过程的化学-物理变化会改变其介电性质。我们通过研究聚烯烃老化过程介电性质的变化来测定其老化程度。
Polyolefins have excellent mechanical properties and electrical properties, in the production sector has been widely used. Polyolefins in the processing, storage and use of the process will be due to various factors, so that its performance deteriorates, resulting in the loss of value. The chemical-physical changes in polyolefin aging process can change its dielectric properties. We study the aging of polyolefins dielectric properties of the changes to determine the degree of aging.
