Abstract
The invention discloses a high-conductivity galvanized steel sheet. The high-conductivity galvanized steel sheet comprises rolled steel as a base layer (1), a galvanized layer (2) outside the base layer (1), and a surface treatment skin film (3) outside the galvanized layer (2), wherein the thickness of the surface treatment skin film (3) is 0.65-0.75 micron, the surface roughness of the surface treatment skin film (3) is uniform and is Ra1.5 to Ra1.6. According to the high-conductivity galvanized steel sheet, the thickness of the surface treatment skin film is 0.65-0.75 micron, the uniform roughness is Ra1.5 to Ra1.6, and relative certain degree of finish can be realized, thus the high-conductivity galvanized steel sheet is beneficial to improvement of the corrosion resistance; therefore, the corrosion resistance is not reduced while the thickness of the skin film is decreased to 0.65-0.75 micron from conventional 0.8-1 micron, and the conductivity of the steel sheet surface is improved on the basis that the corrosion resistance of the galvanized layer surface is ensured.
Description
Technical field
The present invention relates to a kind of galvanized steel plain sheet, specifically a kind of high conduction galvanized steel plain sheet.
Background technology
Galvanized steel plain sheet is applied more extensive in building, household electrical appliances, automobile, and it is a kind of steel plate at steel surface plating or hot dip layer of metal zinc, thereby plays etch-proof effect.
Galvanized steel plain sheet is commonly used for counter body, galvanized wire is in the time producing the galvanized steel plain sheet that is used as counter body, in Chu Fang ﹑ Yun Shu ﹑ use procedure, avoid product surface coating directly to contact and cause oxidation and rusting with air for guaranteeing product, therefore all can use aborning the resistance to finger prints processing of surperficial environmental protection, at zinc coat, surface treatment epithelium is set outward, the data that provide by medicament supplier and actual needs, the medicament thickness of surface treatment epithelium is 0.8～1.0um, can reach the corrosion resistance requirement of customer requirement.
But the treatment agent film thickness of 0.8～1.0um will cause surface of steel plate impedance excessive, like this part of galvanized steel sheet surface cannot conduct electricity or electric conductivity bad.
If the thickness of surface treatment epithelium does not reach 0.8～1.0um, its decay resistance is by degradation.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high conduction galvanized steel plain sheet, and this steel plate suitably reduces surface treatment leather film thickness, improves the uniformity of product surface roughness, improves surface of steel plate electric conductivity.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of high conduction galvanized steel plain sheet, comprise as the zinc coat outside steel, the basic unit of basic unit and the surface treatment epithelium outside zinc coat, described surface treatment leather film thickness is 0.65～0.75 μ m, the even surface roughness of described surface treatment epithelium, and its roughness is Ra1.5～Ra1.6.
Described surface treatment leather film thickness is 0.65 μ m preferably.
Surface treatment leather film thickness of the present invention is at 0.65～0.75 μ m, coordinate the even roughness degree of Ra1.5～Ra1.6, this roughness has certain fineness relatively, therefore contribute to improve decay resistance, therefore in the time dropping to 0.65～0.75 μ m by 0.8～1 μ m of routine, do not reduce its decay resistance at leather film thickness.
But this combination identity is larger, the first roughness of surface uniform, can solve surface of steel plate and have the problem that local conductivity can be not good, and the surface treatment leather film thickness reducing is more conducive to improve the electric conductivity of surface of steel plate.Thereby galvanized steel plain sheet of the present invention is guaranteeing, on the corrosion proof basis of coating surface, to improve the electric conductivity of surface of steel plate.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of high conduction galvanized steel plain sheet, comprises as the zinc coat 2 outside steel, the basic unit 1 of basic unit 1 and the surface treatment epithelium 3 outside zinc coat 2, surface treatment epithelium 3 forms after being applied by chromium-free fingerprint-resistant liquid, there is good corrosion resisting property, and resistance to fingerprint.Chromium-free fingerprint-resistant fluid component mostly is resin, and for example disclosed metal conditioner of patent EP1426466A1 is coordinated and forms with water by the resins such as the polyurethane resin of cationic or nonionic, acrylic resin, epoxy resin and particular technology element.
Common product is for guaranteeing corrosion resistance, and required surface treatment epithelium 3 thickness are 0.8～1.0um, but this thickness is the compromise on the basis of sacrificial surface electric conductivity, can cause local non-conductive.Surface treatment epithelium 3 thickness of the present invention are 0.65～0.75 μ m, preferably 0.65 μ m, and 0.7 μ m thickness is also a good selection.
In addition, the even surface roughness of described surface treatment epithelium 3, its roughness is limited to Ra1.5～Ra1.6.Increase the roughness uniformity of product surface with the modified work roller of EDT texturing, better to reduce surface impedance, improve electrical conductivity.
The present invention reduces surface treatment epithelium 3 thickness, thereby reduces the impact of resinous principle on steel plate electric conductivity in surface treatment epithelium 3, coordinates even roughness degree, is guaranteeing, on the corrosion proof basis of coating surface, to improve the electric conductivity of surface of steel plate.
Above-described embodiment does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
