Description

Technical Field

[0001] The utility model relates to the technical field of galvanized flat wires, in particular to a galvanized flat wire which has high brightness and is not prone to rust. Background Art

[0002] Galvanized flat wire is a type of metal wire made by coating a flat metal wire (usually mild steel) with zinc. It is widely used in construction, agriculture, handicrafts, decoration, packaging and other industrial fields.

[0003] Galvanized flat wire is made by coating the surface of low-carbon steel flat wire with a layer of zinc. Although this treatment method provides a certain degree of corrosion resistance, in actual application, it may affect the quality and performance of the galvanized layer. Because during transportation, installation or use, the zinc layer of the galvanized flat wire will be damaged by scratches, wear, cutting, etc., thereby reducing the corrosion resistance of the galvanized layer. Therefore, a galvanized flat wire with high brightness and low rust resistance is proposed here to solve the above technical problems. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a galvanized flat wire with high brightness and not easy to rust. It has the advantages of not easy to rust, etc., and solves the problem that the zinc layer of the galvanized flat wire may be damaged by scratches, wear, cutting, etc. during transportation, installation or use, thereby reducing the anti-corrosion performance of the galvanized layer.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a galvanized flat wire with high brightness and low rust resistance, comprising a base material layer and a protective component;

[0006] The protective component is arranged on the outside of the base material layer to improve the corrosion resistance of the galvanized flat wire;

[0007] The protective component includes a galvanized layer, a passivation layer and a brightening layer. The galvanized layer is arranged on the outside of the substrate layer to cover the surface of the substrate layer to form a key protective layer. The passivation layer is arranged on the outside of the galvanized layer. The brightening layer is sprayed on the outside of the passivation layer to increase the surface brightness of the galvanized flat wire.

[0008] Furthermore, the substrate layer is a low-carbon steel layer, and the cross section of the substrate layer is rectangular.

[0009] Furthermore, the galvanized layer is a zinc material covering layer, and the outer surface of the galvanized layer is mirror-finished to improve the glossiness.

[0010] Furthermore, the passivation layer is a chromate passivation film layer, which is used to form a dense oxide film on the surface of the zinc layer.

[0011] Furthermore, the brightening layer is an acrylic emulsion coating, which is applied on the surface of the galvanized flat wire to form a uniform and bright protective layer.

[0012] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0013] This galvanized flat wire has high brightness and is not prone to rust. The base layer is made of low-carbon steel, which ensures the mechanical strength and toughness of the galvanized flat wire and is suitable for various load-bearing and structural applications. The galvanized layer serves as a key protective layer to effectively prevent the base material from rusting, and the addition of the passivation layer further enhances the corrosion resistance of the galvanized layer, forming a dense oxide film to protect the galvanized layer from oxidation and corrosion. The addition of the brightening layer not only improves the appearance and texture of the galvanized flat wire, but also provides additional protection, allowing it to maintain a long service life in harsh environments such as humidity and high salinity, effectively reducing long-term operating costs.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1 to 2 In this embodiment, a galvanized flat wire with high brightness and low rust resistance includes a base material layer 1 and a protective component 2.

[0020] Example 2: Please refer to Figures 2 to 3 On the basis of the first embodiment, the protective component 2 in this embodiment is arranged on the outside of the base material layer 1 to improve the corrosion resistance of the galvanized flat wire.

[0021] The protective component 2 includes a galvanized layer 21, a passivation layer 22 and a brightening layer 23. The galvanized layer 21 is arranged on the outside of the substrate layer 1 to cover the surface of the substrate layer 1 to form a key protective layer. The galvanized layer 21 covers the outside of the substrate layer 1 to form a key protective layer to prevent the substrate layer 1 from being directly exposed to a corrosive environment. The galvanized layer 21 is formed by an electroplating process, and its outer surface is mirror-finished to improve gloss and corrosion resistance. When the zinc layer is damaged, the rusted iron is converted into a corroded zinc layer through the effect of sacrificial anode protecting cathode, thereby protecting the iron substrate from corrosion. The passivation layer 22 is arranged on the outside of the galvanized layer 21, and the brightening layer 23 is sprayed on the outside of the passivation layer 22 to increase the surface brightness of the galvanized flat wire.

[0022] In this embodiment, the substrate layer 1 is a low-carbon steel layer, and the cross-section of the substrate layer 1 is rectangular. The substrate layer 1 is the core part of the galvanized flat wire and is usually made of low-carbon steel to provide the necessary mechanical strength and toughness. The galvanized layer 21 is a zinc covering layer, and the outer surface of the galvanized layer 21 is mirror-finished to improve the gloss. The passivation layer 22 is a chromate passivation film layer for forming a dense oxide film on the surface of the zinc layer. The passivation layer 22 is arranged on the outside of the galvanized layer 21 and is usually a chromate passivation film layer for forming a dense oxide film on the surface of the zinc layer. This oxide film can further protect the galvanized layer 21 to prevent the zinc layer from being oxidized or corroded, and also helps to improve the corrosion resistance of the galvanized layer 21. The brightening layer 23 is an acrylic emulsion coating for being applied to the surface of the galvanized flat wire to form a uniform and bright protective layer.

[0023] It should be noted that the brightening layer 23 is the outermost layer, which not only provides additional protection, but also increases the surface brightness of the galvanized flat wire and improves the appearance and texture of the product. The coordinated use of each layer structure forms a comprehensive protection system, which not only protects the substrate from corrosion, but also improves the appearance quality and performance of the product.

[0024] The working principle of the above embodiment is:

[0025] The galvanized layer 21 is in direct contact with the substrate layer 1, providing the first layer of protection to prevent the substrate from rusting. The passivation layer 22 forms a dense oxide film on the galvanized layer 21, enhancing the overall corrosion resistance and protecting the galvanized layer 21 from erosion. The brightening layer 23 is the outermost layer, which not only provides additional protection, but also increases the surface brightness of the galvanized flat wire and improves the appearance texture of the product. The coordinated use of each layer structure forms a comprehensive protection system, which not only protects the substrate from corrosion, but also improves the appearance quality and performance of the product.

[0026] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0027] If this patent discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, using bolts or screws to connect), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by a casting process) (except where it is obviously impossible to use an integrated forming process).

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
