1, the conductive substance exhaled and polluted OPC.
The charging roller will add conductive material during the process of conducting electrical conduction. Conductive materials are mainly carbon black and ionic conductive materials. OPC is easily precipitated by ionic conductive materials in polymer materials. The use of conductive materials, no precipitation, no pollution, through many years of customer use, has proved no pollution.
2, other materials are precipitated, which affect the electrical properties of PCR.
During the production and storage process, other materials added to the charging roll membrane sleeve may be precipitated, which will affect the electrical and physical properties of PCR and cause bad results. No other material is added to the production process of the film sleeve, so as to keep the stability of the film sleeve and other physical properties.
As far as the charging roller is concerned, the charge is mainly on the drum core, and the charge on the surface of the drum is mainly determined by the charge voltage of the drum core. How many is the decision of the drum core, which is determined by the charging roller.
