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
The present invention relates to the chemically treated method in metallic surface, particularly a kind of making method of ceramic toner cartridge developing magnetic roll aluminium cover.
Background technology
Magnetic rod in the toner cartridge is the important accessory of laser printer, duplicating machine or facsimile recorder; The magnetic rod is made up of at the conduction contact head and the two ends plastic cement spacer sleeve of aluminium cover the aluminium cover that has adsorption layer, plant magnetic core, close-fitting within it usually; Under the action of a magnetic field of magnetic core; Carbon dust is attracted to aluminium cover adsorption layer surface, and after the toner cartridge energising, the aluminium cover is arranged carbon dust and transferred on the photosensitive drum surface.This shows that aluminium overlaps the quality of surperficial carbon dust adsorption layer, will directly have influence on drop shadow effect and quality, so the surface treatment of aluminium cover is the most crucial technology of magnetic roller, require it to have wear-resisting, conduction and characteristic such as roughness uniformly.Common surface treatment is conduction spraying or sandblast break-in, and the adsorption layer surface particles that conduction spraying or sandblast break-in are processed is thicker, and uniformity coefficient is relatively poor, and its complete processing is complicated, and manufacturing cost is higher.
The previous one Chinese patent application of our company number is: 200510126681.7, denomination of invention " durable high uniformity toner cartridge developing magnetic roller aluminium pipe sleeve and method of manufacture " has utilized the nickel plating resist to come contacting of air-isolation and corrosion adsorption layer, has overcome the defective that the corrosion adsorption layer is prone to oxidation; Utilize the hardness of nickel plating resist to improve the wear resistance of corroding adsorption layer simultaneously.But in actual use, electroconductibility, oxidizability and the wear resistance of aluminium cover surface absorbed layer still need further improvement.
Summary of the invention
The objective of the invention is deficiency, provide a kind of and prevent the oxidation of aluminium cover surface absorbed layer, improve the making method that its wear resistance also improves the ceramic toner cartridge developing magnetic roll aluminium cover of its electroconductibility simultaneously to above-mentioned developing magnetic roll aluminium cover.
The objective of the invention is to realize like this:
A kind of making method of ceramic toner cartridge developing magnetic roll aluminium cover comprises following operation in order:
(1) the roughened operation is carried out in the direct sandblast of aluminium matter sleeve surface;
(2) in the operation of the chemical plating nickel-phosphorus alloy resist that plating total thickness on the aluminium matter sleeve pipe of frosted layer＜5 μ m are arranged and electroless plating pottery and nickel-phosphorus alloy resist.
The white fused alumina that adopts sandblast machine that 80～280 purpose sub-sieves sieve is got in the said operation (1) carries out sandblast to aluminium matter sleeve pipe.
The blasting pressure of said sandblast machine is 0.15～0.25MP, and the sandblast distance is 8～12CM, sprays altogether twice at the uniform velocity back and forth with 25～35 seconds/inferior speed.
Said operation (2) may further comprise the steps: electrochemical deoiling → pickling → soak zinc → move back zinc → secondary soaking zinc → chemical plating nickel-phosphorus alloy → electroless plating pottery and nickel-phosphorus alloy → drying.
Said electroless plating pottery and nickel-phosphorus alloy step are specially: adopt Teflon 90～110g/L, single nickel salt 180～220g/L, sodium acetate 40～60g/L; Trisodium Citrate 40～60g/L; Inferior sodium phosphate 180～220g/L, PH are 4.6～4.8, and treatment temp is 85～95 ℃; Treatment time is 8～12 minutes, and pure water cleans.
The principle of the making method of the present invention's pottery toner cartridge developing magnetic roll aluminium cover is: utilize blasting method can remove the zone of oxidation and the impurity on aluminium cover surface, and can make it produce uniform roughness, have and the better bonding force of coating; Chemistry once soaks zinc, can remove zinc layer on sull and the ability uniform deposition effectively, prevents that aluminum substrate from reoxidizing, and through secondary soaking zinc, the zinc layer is more even, careful, and is better with basal body binding force; Utilize chemical plating nickel-phosphorus alloy layer and electroless plating pottery and ni-p alloy coating to improve the wear resistance and the electroconductibility of surface absorbed layer simultaneously.
The present invention is on the basis that keeps aluminium cover surface adsorption trickle degree of floor height particle and uniformity coefficient; The chemical plating nickel-phosphorus alloy layer of plating and pottery and nickel-phosphorus alloy resist can improve the work-ing life of aluminium cover greatly; Simultaneously because the combination of chemical plating nickel-phosphorus alloy, electroless plating pottery and nickel-phosphorus alloy, blasting method and secondary soaking zinc technology; Improved the electroconductibility and the wear resistance of aluminium cover surface absorbed layer, reduced its oxidisability, thereby obviously improved each item performance of common developing magnetic roll.
