Example Embodiment

[0016] Example 1

[0017] The present invention includes the following steps in order:

[0018] (1) The surface of aluminum casing is directly sandblasted for roughening treatment process, including the following steps:

[0019] A. Perform conventional chemical degreasing, water washing, and light-emitting cleaning treatments on aluminum casing;

[0020] B. Cover both ends of the cleaned aluminum casing with protective sleeves processed with silica gel, and put them into the sandblasting machine. Use the sandblasting machine to spray the glass beads from the 180-mesh sample sieve on the aluminum casing. Sand, the blasting pressure is 0.2MP, the blasting distance is 10CM, and it is sprayed twice at a constant speed of 30 seconds / time.

[0021] C. Insert the sandblasted aluminum casing into the fixture and put it into the air shower room to remove the remaining glass beads for later use.

[0022] (2) The process of plating an electroless nickel-phosphorus alloy protective layer and an ele...

[0031] Example 2

[0032] Example 1 was repeated according to the same steps, but in step B of step (1), the aluminum casing was blasted with white corundum, which was screened by a 280-mesh sieve with a sandblasting machine, and the blasting pressure of the sandblasting machine was 0.25MP, blasting distance of 12CM, spraying twice at a constant speed of 35 seconds / time. Step (2) In Step G, use Teflon 90g / L, nickel sulfate 220g / L, sodium acetate 60g / L, sodium citrate 40g / L, sodium hypophosphite 180g / L, pH 4.6~4.8, treatment temperature The temperature is 95°C, the treatment time is 12 minutes, and it is washed with pure water.

Example Embodiment

[0033] Example 3

[0034] Example 1 was repeated according to the same steps, but in step B of step (1), the aluminum casing was blasted with white corundum that was screened by a blasting machine with 80 meshes. The blasting pressure of the blasting machine was 0.15MP, sandblasting distance is 8CM, spraying back and forth twice at a constant speed of 25 seconds / time. Step (2) In Step G, use Teflon 110g / L, nickel sulfate 180g / L, sodium acetate 40g / L, sodium citrate 60g / L, sodium hypophosphite 220g / L, pH 4.6~4.8, treatment temperature The temperature is 85°C, the treatment time is 12 minutes, and it is washed with pure water.

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...
