Abstract
The invention provides a manufacturing method of a magnetic roller and a developing roller. The manufacturing method comprises the following steps of: providing an aluminum tube as a base material of the magnetic roller or the developing roller, and using an acidic degreasing agent for degreasing treatment for the surface of the aluminum tube to remove substances and an oxide layer on the surface of the aluminum tube; using an alkaline solution for treating the surface of the aluminum tube to neutralize the residual acidic degreasing agent on the surface of the aluminum tube; using an acidic solution for deashing the surface of the aluminum tube and neutralizing the residual alkaline solution on the surface of the aluminum tube; adopting a sanding agent for generating a conductive layer on the surface of the aluminum tube; and using a passivator for passivation for the conductive layer on the surface of aluminum tube. The manufacturing method is simple in process, and the conductive layer on the surface of the manufactured magnetic roller or the developing roller has the advantages of good conductivity, uniform roughness, corrosion resistance and wear resistance.
Description
Technical field
The present invention relates to member manufacturing method in the electrostatic latent image device, a kind of specifically magnetic roller of the aluminum base material of electrostatic latent image devices such as laser printer, xerographic printer, facsimile recorder, method of manufacture of developer roll of being used for.
Background technology
According to static camera technique principle, the imaging system in the electrostatic latent image devices such as laser printer, xerographic printer, facsimile recorder mainly is made up of magnetic roller, developer roll, cartridge, powder delivery cutter, photosensitive drums.The carbon dust of employed magnetic roller, developer roll and cartridge output, the friction of powder delivery cutter; Form " carbon dust mist " layer of astragal electricity around left magnetic roller, the developer roll; Photosensitive drums is produced the image electrostatic latent image by laser radiation, is attracted to photosensitive drum surface to charged carbon dust; Be transferred on the paper through transfer roll, thus the image transfer process of equipment such as completion laser printer, xerographic printer, facsimile recorder.In the laser imaging process, the roughness of the electroconductibility of magnetic roller, developer roll, surface conduction layer is the key factor that influences image quality.In conventional art, magnetic roller, developer roll are easy to damage, and directly cause the colour density of image not enough, defectives such as carbon dust is excessive, bottom ash.
Summary of the invention
In view of the above problems, the invention provides a kind of magnetic roller of the aluminum base material of electrostatic latent image devices such as laser printer, xerographic printer, facsimile recorder, method of manufacture of developer roll of being used for.。
In order to achieve the above object, the present invention has adopted following technical scheme:
The method of manufacture of a kind of magnetic roller, developer roll may further comprise the steps:
A, the base material of an aluminum pipe as magnetic roller or developer roll is provided, and uses the acid deoiling agent that aluminum tube surfaces is carried out oil removal treatment, remove aluminum tube surfaces material and zone of oxidation;
B, use basic soln are handled the surface of aluminum pipe, and neutralization remains in the acid deoiling agent of aluminum tube surfaces;
C, use the surperficial dedust of acidic solution, and neutralization remains in the basic soln of aluminum tube surfaces to aluminum pipe;
D, the agent of employing sand face generate a conductive layer in aluminum tube surfaces;
E, use passivator carry out Passivation Treatment to the conductive layer of aluminum tube surfaces.
As optimal technical scheme of the present invention: use basic soln to be sodium hydroxide solution in the said b step.
As optimal technical scheme of the present invention: the acidic solution that uses in the said c step is salpeter solution.
As optimal technical scheme of the present invention: the sand face agent of using in the said d step is made up of matt salt and the agent of bright acid sand face.
As optimal technical scheme of the present invention: it is that the matt salt of 62-160g/L, the bright acid sand face agent that mass percentage concentration is 35-100g/L are formed according to 62.5%, 37.5% weight percent that mass percentage concentration is adopted in said sand face agent.
As optimal technical scheme of the present invention: the passivator that the sand face agent of using in the said e step is used is trivalent chromium.
Compared with prior art, technology of the present invention is simple, and the magnetic roller of manufacturing, developer roll, its surperficial conductive layer have good conductivity, even, corrosion-resistant, the anti abrasive advantage of roughness.
Embodiment
The method of manufacture of a kind of magnetic roller, developer roll may further comprise the steps:
The base material of one aluminum pipe as magnetic roller or developer roll is provided, aluminum pipe is put into acid rinse bath, use the acid deoiling agent that aluminum tube surfaces is carried out oil removal treatment, remove aluminum tube surfaces material and zone of oxidation.
Then, aluminum pipe is put into alkaline rinse bath, use sodium hydroxide solution that further processing is done on the surface of aluminum pipe, neutralization remains in the acid deoiling agent of aluminum tube surfaces.
Then, once more aluminum pipe is put into acid rinse bath, use the surperficial dedust of salpeter solution, and neutralization remains in the sodium hydroxide solution of aluminum tube surfaces aluminum pipe.
Aluminum pipe is put into sand launder after above-mentioned surface treatment, use the agent of sand face to generate a conductive layer in aluminum tube surfaces; Comparatively preferred scheme; It is that the matt salt of 62-160g/L, bright acid sand face agent that mass percentage concentration is 35-100g/L are carried out proportioning according to 62.5%, 37.5% weight percent that mass percentage concentration is adopted in the agent of sand face; Temperature of reaction 40-55 ℃, time 3-10 minute.
At last, use the passivator trivalent chromium that the conductive layer of aluminum tube surfaces is carried out Passivation Treatment
The above is merely preferred embodiment of the present invention, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all covered by the scope of claims of the present invention.
