Description

Technical Field

[0001] This utility model relates to the field of galvanized wire technology, specifically to an electro-galvanized wire with good corrosion resistance. Background Technology

[0002] Electro-galvanized wire is a type of metal wire that is coated with a layer of zinc on the surface of low-carbon steel through electroplating to improve its corrosion resistance and aesthetics. Electro-galvanized wire has a wide range of applications, including the manufacture of metal wire mesh, highway guardrails, construction, handicrafts, medical devices, and communication equipment.

[0003] When iron wire undergoes electro-galvanizing, it is prone to poor corrosion resistance. This is because the zinc coating formed by electro-galvanized wire is usually thin and is very easy to wear and damage during use. When the zinc coating is damaged, the underlying base metal will be exposed, leading to rust and affecting the service life of the electro-galvanized wire. Therefore, this paper proposes an electro-galvanized wire with good corrosion resistance to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electroplated zinc wire with good corrosion resistance. It has advantages such as good corrosion resistance and solves the problem that the zinc coating formed by electroplated zinc wire is usually thin and is very easy to wear and damage during use. When the zinc coating is damaged, the underlying base metal will be exposed, leading to rust.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electroplated zinc wire with good corrosion resistance, comprising a base metal layer and an anti-corrosion component disposed on the outside of the base metal layer;

[0006] The anti-corrosion component includes a first galvanized layer disposed on the outside of the base metal layer, and a second galvanized layer disposed on the outside of the first galvanized layer for forming a high-strength galvanized layer on the surface of the base metal layer. An extension layer is disposed on the outside of the second galvanized layer to increase the elongation and tensile properties of the electroplated zinc wire. An anti-corrosion layer is disposed on the outside of the extension layer, and a wear-resistant layer is disposed on the outside of the anti-corrosion layer.

[0007] Furthermore, the base metal layer is a low-carbon steel wire rod layer, used as the metal base layer for electroplated zinc wire.

[0008] Furthermore, both the first zinc plating layer and the second zinc plating layer are electroplated zinc plating layers, and the thickness of the second zinc plating layer is greater than the thickness of the first zinc plating layer.

[0009] Furthermore, the extended layer is a zinc alloy layer.

[0010] Furthermore, the anti-corrosion layer is a passivating agent coating to protect the electroplated zinc wire from corrosion.

[0011] Furthermore, the wear-resistant layer is a hard alloy coating to strengthen the outer layer of the electroplated zinc wire and prevent damage to the zinc layer.

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

[0013] This highly corrosion-resistant electroplated zinc wire features multiple protective layers on the outside of the base metal layer, including two zinc plating layers and a passivating agent coating. This significantly improves the corrosion resistance of the electroplated zinc wire, enabling it to maintain a long service life even under harsh environmental conditions. The addition of an extension layer enhances the wire's ductility when stretched or bent, reducing the risk of breakage due to stress concentration. Through the synergistic effect of the various protective layers, a comprehensive protective system is formed, which not only improves the corrosion resistance of the electroplated zinc wire but also enhances its mechanical properties in practical use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figures 1 to 3 In this embodiment, an electroplated zinc wire with good corrosion resistance includes a base metal layer 1 and an anti-corrosion component 2 disposed on the outside of the base metal layer 1.

[0020] Example 2: Please refer to Figures 2 to 3Based on Embodiment 1, in order to improve the corrosion resistance of the electroplated zinc wire, the anti-corrosion component 2 in this embodiment includes a first zinc plating layer 21 disposed on the outside of the base metal layer 1. The first zinc plating layer 21 is directly plated on the base metal layer as a first layer of zinc, which provides preliminary protection for the base metal layer 1, prevents corrosion and enhances the corrosion resistance of the base metal layer 1. A second zinc plating layer 22 is disposed on the outside of the first zinc plating layer 21 to form a high-strength zinc plating layer on the surface of the base metal layer 1. The second zinc plating layer 22 is located outside the first zinc plating layer 21 and has a greater thickness than the first zinc plating layer 21, further enhancing the corrosion resistance and strength of the electroplated zinc wire. The presence of the second zinc plating layer 22 enables the electroplated zinc wire to maintain a long service life even in harsh environments. An extension layer 23 is disposed on the outside of the second zinc plating layer 22 to increase the elongation and tensile properties of the electroplated zinc wire. An anti-corrosion layer 24 is disposed on the outside of the extension layer 23, and a wear-resistant layer 25 is disposed on the outside of the anti-corrosion layer 24.

[0021] In this embodiment, the base metal layer 1 is a low-carbon steel wire rod layer, which is used as the metal base layer for the electroplated zinc wire. The first zinc layer 21 and the second zinc layer 22 are both electroplated zinc layers, and the thickness of the second zinc layer 22 is greater than the thickness of the first zinc layer 21. The extension layer 23 is a zinc alloy layer. The extension layer 23 is made of zinc alloy and is located outside the second zinc layer 22. The main function of this layer is to increase the extension and tensile properties of the electroplated zinc wire, so that the electroplated zinc wire is not easy to break when stretched or bent, thereby improving its flexibility and durability in practical applications.

[0022] In this embodiment, the anti-corrosion layer 24 is a passivating agent coating to protect the electroplated zinc wire from corrosion. The anti-corrosion layer 24 is composed of a passivating agent coating, which can form a dense protective film to further prevent corrosive media from penetrating into the interior of the electroplated zinc wire, thereby protecting the electroplated zinc wire from corrosion. The wear-resistant layer 25 is a hard alloy coating to strengthen the outer layer strength of the electroplated zinc wire and prevent the zinc layer from being damaged. The wear-resistant layer 25 is composed of a hard alloy coating, which improves the wear resistance of the electroplated zinc wire, protects the internal zinc layer from wear and damage, and extends the service life of the electroplated zinc wire.

[0023] The working principle of the above embodiments is as follows:

[0024] The first zinc plating layer 21 is directly plated onto the base metal layer 1, providing initial protection against corrosion and enhancing its corrosion resistance. The second zinc plating layer 22 is located outside the first zinc plating layer 21 and is thicker than the first zinc plating layer 21, further enhancing the corrosion resistance and strength of the electroplated zinc wire. The presence of the second zinc plating layer 22 allows the electroplated zinc wire to maintain a long service life even in harsh environments. The extension layer 23 is made of zinc alloy and is located outside the second zinc plating layer 22. The main function is to increase the ductility and tensile properties of the electro-galvanized wire, making it less prone to breakage when stretched or bent, thus improving its flexibility and durability in practical applications. The anti-corrosion layer 24 is composed of a passivating agent coating, which can form a dense protective film to further prevent corrosive media from penetrating into the interior of the electro-galvanized wire, thereby protecting the electro-galvanized wire from corrosion. The wear-resistant layer 25 is composed of a hard alloy coating, which improves the wear resistance of the electro-galvanized wire, protects the internal zinc layer from wear and damage, and extends the service life of the electro-galvanized wire.
