Abstract

The invention provides a method for making a ceramic selenium drum development magnetic roller aluminum sleeve. The method is used for preventing oxidation of an adsorption layer on the surface of the aluminum sleeve, improving the abrasion resistance of the aluminum sleeve and improving the conductivity of the aluminum sleeve at the same time. The method comprises the following processes of: directly blasting sand to the surface of the aluminum sleeve to perform roughening treatment; and coating a chemically plated nickel-phosphorus alloy protective layer with the total thickness of less than 5 microns and a chemically plated ceramic and nickel-phosphorus alloy protective layer on the aluminum sleeve with a frosting layer. On the basis of keeping high particle fineness and uniformity of the adsorption layer on the surface of the aluminum sleeve, the service life of the aluminum sleeve can be greatly prolonged by the coated nickel-phosphorus alloy protective layer and the ceramic and nickel-phosphorus alloy protective layer; and meanwhile, because the chemically plated nickel-phosphorus alloy protective layer, the chemically plated ceramic and nickel-phosphorus alloy protective layer, the sand blasting method and the secondary zinc galvanizing technology are combined, the conductivity and the abrasion resistance of the adsorption layer on the surface of the aluminum sleeve are improved, the oxidation property of the adsorption layer is reduced, and various properties of common development magnetic rollers are obviously improved.

Description

technical field [0001] The invention relates to a method for chemically treating metal surfaces, in particular to a method for manufacturing an aluminum sleeve of a developing magnetic roller of a ceramic toner cartridge. Background technique [0002] The magnetic stick in the toner cartridge is an important accessory for laser printers, copiers or fax machines. The magnetic stick is usually composed of an aluminum sleeve with an adsorption layer, a magnetic core inserted in it, a conductive contact head tightly fitted on the aluminum sleeve, and two ends. Composed of plastic isolation sleeves, under the action of the magnetic field of the magnetic core, the carbon powder is adsorbed on the surface of the adsorption layer of the aluminum sleeve. After the toner drum is powered on, the aluminum sleeve arranges and transfers the carbon powder to the surface of the photosensitive drum. It can be seen that the quality of the carbon powder adsorption layer on the surface of the a...
