Description
Technical Field
The utility model relates to a steel sheet technical field, more specifically say, the utility model relates to a resistant fingerprint galvanized steel sheet.
Background
The galvanized steel sheet is widely applied to the industrial fields of building materials, household appliances, automobiles and the like, and the corrosion resistance of the common steel sheet can be enhanced by coating a galvanized layer on the surface of the common steel sheet as a cathode sacrificial protective layer. On the basis of not changing the mechanical property of the color galvanized steel sheet, the galvanized steel sheet has the appearance of bright color and uniform color, thereby having better decoration.
In small household appliances, DVD, set-top boxes, computer cases, refrigerators, washing machines and other household appliances, a fingerprint-resistant layer needs to be coated on the outer side of a galvanized steel sheet. The fingerprint-resistant plate is a composite coating plate obtained after fingerprint resistance treatment is carried out on the surface of a galvanized plate. The fingerprint-resistant steel plate is a material which passes the environmental protection certification at first, and fingerprints cannot be left due to the fact that the surface of the fingerprint-resistant steel plate is touched by a clean finger, so that the fingerprint-resistant steel plate is named as fingerprint-resistant, the surface of the fingerprint-resistant steel plate is smooth and flat, and the tolerance is small. The initial fingerprint resistance treatment is to form an inorganic series film, generally a silicate film, on a zinc-plated chromate passivation film, thereby imparting fingerprint resistance to the surface of the steel sheet. In recent years, users have made higher demands for plated products, and in addition to fingerprint resistance, grounding properties, higher fingerprint resistance, and coating properties have been demanded. Thus, a coated sheet has been developed in which a thin film type organic composite film is formed on a chromate film of a galvanized steel sheet. The organic type fingerprint-resistant steel plate and the inorganic type fingerprint-resistant steel plate have different performances, the corrosion resistance and the grounding property of the organic type fingerprint-resistant steel plate are better than those of the inorganic type fingerprint-resistant steel plate, but the index of the fingerprint resistance is poorer.
The existing fingerprint-resistant galvanized steel plate has insufficient fingerprint-resistant effect, and the fingerprint-resistant layer is not wear-resistant and is easy to scrape, so that the overall attractiveness of the steel plate is affected.
