Electrical tracking is one of the main reasons for the deterioration of insulation surface. According to the problem of the surface electrical tracking erosion of insulation used in the high-voltage mining cables, the Ethylene Propylene Rubber samples with different electrical tracking development stage were selected in the paper. The relationship between the surface electrical tracking erosion degree...
Degradation behaviors of both the unplasticized and plasticized poly(vinyl chloride) (UPVC and PPVC) under an artificial accelerating aging condition were extensively studied. The dependence of mechanical properties, average molecular weight (MW), and surface morphology of the earlier PVC on aging time was investigated by tensile tests, gel penetrate chromatogram (GPC), and scanning electron microscope...
Phenol is an important and common environmental pollutant. In this study, Pseudomonas aeruginosa HS-D38 strain was used to degrade phenol, and the degradation characteristics were investigated. Results indicated that HS-D38 strain could degrade phenol and utilize it as the sole carbon, nitrogen and energy source. UV-visible spectra analysis showed that 300 mgL-1 phenols could be completely degraded...
