Description

Technical Field

[0001] This utility model relates to the field of metal sheet technology, specifically to a corrosion-resistant and wear-resistant metal sheet. Background Technology

[0002] Metal sheets refer to plate-shaped workpieces made of metal materials. There are many types of metal sheets available today, including iron, aluminum, and copper sheets. Metal sheets are frequently used in the construction industry.

[0003] When metal sheets are used in areas with frequent rainfall, moisture easily adheres to the outer surface of the metal sheet during rainy weather. Prolonged contact with moisture can easily cause corrosion on the outer surface. Therefore, this application proposes a corrosion-resistant and wear-resistant metal sheet to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a corrosion-resistant and wear-resistant metal sheet, which has the advantages of improving the corrosion resistance of metal sheets and solving the problem that prolonged contact with moisture can easily cause rust on the outside.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant and wear-resistant metal sheet, comprising two sheet bodies, a splicing mechanism on the upper part of the sheet bodies, and a protective component on the outer side of the sheet bodies;

[0006] The protective component includes a pressure-resistant layer coated on the outside of the main body of the plate, a heat-resistant layer coated on the outside of the pressure-resistant layer, a toughness layer coated on the outside of the heat-resistant layer, and a cavitation-resistant layer coated on the outside of the toughness layer.

[0007] Furthermore, the protective component also includes a wear-resistant layer coated on the outside of the cavitation-resistant layer, wherein the wear-resistant layer is an iron-based amorphous alloy coating.

[0008] Furthermore, the compressive layer is a carbon fiber coating, and the heat-resistant layer is a nickel-based alloy coating.

[0009] Furthermore, the toughness layer is a carbon nanotube reinforced coating, and the cavitation resistant layer is a polymer wear-resistant coating.

A first arc-shaped groove and a second arc-shaped groove are formed on the upper surface of the main body panel. A positioning hole located on the main body panel is formed on the bottom wall of the inner cavity of the second arc-shaped groove.

[0011] Furthermore, the positioning post slides in an arc shape inside the first arc groove and the second arc groove, and the screw is threaded into the positioning hole.

[0012] Furthermore, there are two splicing mechanisms, which are symmetrically distributed about the central axis of the main body of the board.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] (1) The corrosion-resistant and wear-resistant metal plate has two shaft plates that push the positioning column to slide inside the first arc groove with the center of the shaft rod, and then enter the second arc groove until the positioning column moves to the top of the positioning hole. At this time, the two plate bodies can be spliced ​​by rotating the screw into the positioning hole.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1 The corrosion-resistant and wear-resistant metal sheet in this embodiment includes two sheet bodies 1, a splicing mechanism 2 on the top of the sheet body 1, and a protective component 3 on the outside of the sheet body 1.

[0024] Please see Figures 2 to 3 In this embodiment, the splicing mechanism 2 includes shafts 201 rotatably connected to the upper surfaces of two plate bodies 1. Shaft plates 202 are fixed to the outer sides of the two shafts 201. A positioning post 203 is fixed to the back side of the shaft plate 202 and the end away from the shaft 201. Screws 204 are placed on the upper surface of the shaft plate 202. A first arc groove 205 and a second arc groove 206 are provided on the upper surface of the plate body 1. A positioning hole 207 located on the plate body 1 is provided on the bottom wall of the inner cavity of the second arc groove 206. When the two plate bodies 1 are spliced ​​back and forth, the first arc groove 205 and the second arc groove 206 will form an arc-shaped sliding groove. The arc-shaped sliding groove has an arc trajectory with the shaft 201 as the center, which facilitates the positioning post 203 to slide in the arc-shaped sliding groove.

[0025] There are two splicing mechanisms 2, which are symmetrically distributed about the central axis of the main body 1. The positioning post 203 slides in an arc shape inside the first arc groove 205 and the second arc groove 206. The screw 204 is threaded into the positioning hole 207. The two main bodies 1 are aligned front and back. Then, the two shaft plates 202 push the positioning post 203 to slide inside the first arc groove 205 around the center of the shaft 201, and then enter the second arc groove 206 until the positioning post 203 moves above the positioning hole 207. At this time, the screw 204 can be rotated into the positioning hole 207 to splice the two main bodies 1.

[0026] It is understandable that the two shaft plates 202 are pushed by the center of the shaft 201 to slide the positioning post 203 inside the first arc groove 205, and then enter the second arc groove 206 until the positioning post 203 moves above the positioning hole 207. At this time, the two plate bodies 1 can be spliced ​​by rotating the screw 204 into the positioning hole 207.

[0027] Please see Figures 4 to 5In this embodiment, the protective component 3 includes a pressure-resistant layer 301 coated on the outside of the plate body 1, a heat-resistant layer 302 coated on the outside of the pressure-resistant layer 301, a toughness layer 303 coated on the outside of the heat-resistant layer 302, and a cavitation-resistant layer 304 coated on the outside of the toughness layer 303.

[0028] The protective component 3 also includes a wear-resistant layer 305 coated on the outside of the cavitation-resistant layer 304. The wear-resistant layer 305 is an iron-based amorphous alloy coating. The iron-based amorphous alloy coating of the wear-resistant layer 305 gives the corrosion-resistant and wear-resistant metal sheet excellent wear resistance and corrosion resistance, mainly through thermal spraying technology, such as supersonic flame spraying and arc spraying. The pressure-resistant layer 301 is a carbon fiber coating. The carbon fiber coating on the outside of the pressure-resistant layer 301, due to its lighter weight than aluminum but higher strength than steel, gives the corrosion-resistant and wear-resistant metal sheet high hardness, high strength, light weight, high chemical resistance, and high temperature resistance. The heat-resistant layer 302 is a nickel-based alloy coating. The nickel-based alloy coating of the heat-resistant layer 302 gives the corrosion-resistant and wear-resistant metal sheet excellent wear resistance and corrosion resistance. The abrasive metal sheet exhibits excellent heat resistance, corrosion resistance, and erosion wear resistance. The toughness layer 303 is a carbon nanotube-reinforced coating. By incorporating modified carbon nanotubes, the coating enhances its adhesion to the metal substrate and provides a certain degree of flexibility, thus playing a toughening role. The cavitation resistant layer 304 is a polymer wear-resistant coating. The coating material consists of two components, A and B. Component B is a curing agent, while component A is composed of materials such as silicon carbide and zirconium corundum with different particle sizes. Auxiliary materials include asbestos powder and cast stone powder. It is convenient and quick to apply, has high bonding strength, low cost, and excellent wear resistance, good corrosion resistance, and high cavitation resistance.

[0029] It is understandable that the various coatings applied to its outer surface give the corrosion-resistant and wear-resistant metal sheet high hardness, high strength, light weight, high chemical resistance and high temperature resistance, as well as excellent wear resistance, good corrosion resistance and high cavitation resistance, which significantly improves the practicality of the corrosion-resistant and wear-resistant metal sheet.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, any aspects not detailed in this utility model are well-known technologies to those skilled in the art.

[0031] The working principle of the above embodiments is as follows:

[0032] When the corrosion-resistant and wear-resistant metal sheet is required, align the two sheet bodies 1 front to back, then push the positioning post 203 inside the first arc groove 205 with the center of the shaft 201 of the two shaft plates 202, and then enter the inside of the second arc groove 206 until the positioning post 203 moves above the positioning hole 207. At this time, the two sheet bodies 1 can be spliced ​​by rotating the screw 204 into the positioning hole 207.

[0033] The outer anti-compression layer 301, composed of a carbon fiber coating, provides the corrosion-resistant and wear-resistant metal sheet with high hardness, high strength, light weight, high chemical resistance, and high temperature resistance due to the lighter weight of carbon fiber compared to aluminum but higher strength than steel. The heat-resistant layer 302, composed of a nickel-based alloy coating, gives the sheet excellent heat resistance, corrosion resistance, and erosion wear resistance. The toughness layer 303, composed of a carbon nanotube-reinforced coating, enhances the adhesion between the coating and the metal substrate by incorporating modified carbon nanotubes, and also provides a certain degree of flexibility, thus toughening the sheet. The coating material consists of a polymer wear-resistant coating layer 304, which is composed of two components, A and B. Component B is a curing agent, while component A is composed of materials such as silicon carbide and zirconium corundum with different particle sizes. Auxiliary materials include asbestos powder and cast stone powder. It is convenient and quick to apply, has high bonding strength, and low cost. It has excellent wear resistance, good corrosion resistance, and high cavitation resistance. The wear-resistant layer 305 is composed of an iron-based amorphous alloy coating, which gives the corrosion-resistant and wear-resistant metal sheet excellent wear resistance and corrosion resistance. This is mainly achieved through thermal spraying technology, such as supersonic flame spraying and arc spraying.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
