Electric Field Induced Orientation of Montmorillonite in Polyethylene and Properties of Electrical Tree Growing in This Composite
摘要
Abstract
To improve the electrical tree resistance capability of low-density polyethylene (LDPE), a novel method is proposed to orientate the montmorillonite (MMT) in LDPE by electric field inducing treatment. A new orientation setup was designed and manufactured. A set-up for electrical inducement was designed to realize the orientation of the MMT in LDPE/MMT composite material. The effect of electrical inducing orientation was characterized by the measurement results of X-ray diffraction (XRD), transmittivity of UV, scanning electron microscope (SEM) of surface and cross-section. The initiation and propagation properties of electrical trees in the LDPE/MMT before and after electrical inducing treatment were investigated and compared. The results indicate that the electrical field inducement contributes to the MMT disperse uniformly in LDPE and make the MMT layers turn along the direction parallel to the electrical field. The LDPE/MMT after electrical inducing has better capability to suppress the electrical trees under power frequency field.关键词
