Decay of electric charge on corona charged polyethylene

Decay of electric charge on corona charged polyethylene
Decay of electric charge on corona charged polyethylene
This paper describes a study on the surface potential decay of corona charged low density polyethylene (LDPE) films. A conventional corona charging process is used to deposit charge on the surface of the film and the surface potential is measured by a compact JCI 140 static monitor. The results obtained from corona charged multi-layer sample reveal that the bulk process dominates charge decay. In addition, the pulsed-electro-acoustic (PEA) technique has been employed to monitor charge profiles in corona charged LDPE film. By using the PEA technique, we are able to monitor charge migration through the bulk. Charge profiles in corona charged multilayer sample are consistent with surface potential results. Of further significance, the charge profiles clearly demonstrate that the double injection has taken place in corona charged LDPE films.

Abstract

This paper describes a study on the surface potential decay of corona charged low density polyethylene (LDPE) films. A conventional corona charging process is used to deposit charge on the surface of the film and the surface potential is measured by a compact JCI 140 static monitor. The results obtained from corona charged multi-layer sample reveal that the bulk process dominates charge decay. In addition, the pulsed-electro-acoustic (PEA) technique has been employed to monitor charge profiles in corona charged LDPE film. By using the PEA technique, we are able to monitor charge migration through the bulk. Charge profiles in corona charged multilayer sample are consistent with surface potential results. Of further significance, the charge profiles clearly demonstrate that the double injection has taken place in corona charged LDPE films.
