Description
Technical Field
The invention relates to an OPC drum and a corresponding processing method thereof, in particular to a processing method of a electronegative multilayer OPC drum, belonging to the technical field of organic photoconductors.
Background
An Organic Photoconductor (OPC) is an important material widely used in the industries of laser printing, digital copying and the like, and an OPC drum is a photoelectric conversion device formed by coating an OPC material on the surface of a conductive aluminum cylinder and is characterized in that an insulator is arranged in a dark place, a certain electrostatic charge can be maintained, and when light with a certain wavelength is irradiated, the insulator becomes a conductor and releases the charge through an aluminum base, and finally an electrostatic latent image is formed. The surface condition of the OPC drum, which is a heart component of a laser printer system, has a direct influence on the effectiveness of the laser printer system, and directly determines whether the laser printer or copier is operating normally and can output high-quality, flawless documents.
In the existing OPC drum processing process, due to the metal characteristics of a base material tube, cracks, pinholes and irregular threads are easy to appear on the surface of the base material tube in the processes of drawing and lathe processing. Under the influence of the light-emitting device, when the non-background light conductor series products are coated subsequently, part of the products are easy to generate breakdown, point emergence and diffraction patterns, so that the output quality of manuscripts is influenced.
In order to solve the problem, the current solution in the industry is to increase the thickness of a charge blocking layer (UCL) on the surface of the OPC drum, and thus to cover the cutting lines on the surface of the green tube, pinholes, cracks, etc. generated by drawing the surface of the green tube. In the actual application process, however, technicians find that, because the current charge blocking layer material has a relatively general sagging property, increasing the thickness of the charge blocking layer on the surface of the OPC drum will result in poor uniformity of subsequent coating of the product, thereby affecting the use effect of the product.
In summary, a need exists in the art for a novel method for manufacturing an OPC drum, which can ensure the yield of the manufactured OPC drum and greatly improve the voltage breakdown resistance of the surface coating of the OPC drum.
