Description

Technical Field

[0001] This invention relates to the field of wire mesh manufacturing technology, specifically a method for preparing wire mesh. Background Technology

[0002] Traditional wire mesh is made solely through weaving, that is, by interlacing warp and weft threads to form a fine mesh. However, it has the disadvantages of being dense and heavy.

[0003] Therefore, providing a method for preparing wire mesh is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides a method for preparing wire mesh to achieve lightweighting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A method for preparing a wire mesh includes the following steps: After the wire mesh is woven, it is rolled to cause the wire mesh to deform laterally and / or longitudinally. By adopting the above technical solutions, the present invention produces beneficial effects: The woven wire mesh is rolled (secondary processing) to make the surface of the wire mesh flatter and smoother. The wire is deformed by pressing, which reduces the mesh spacing and the weight per unit area of ​​the same mesh size. At the same time, the deformation at the warp and weft overlap position is large, making the wire less prone to displacement, which further enhances the stability of the wire mesh.

[0006] Furthermore, before the wire mesh is rolled, the cross-section of the wire is circular; after the wire mesh is rolled, the cross-section of the wire is square.

[0007] Furthermore, the rolling process employs twin-roll rolling, hydraulic press pressing, or single-roll pressing.

Detailed Implementation

[0009] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0010] like Figure 1-5 As shown in the figure, an embodiment of the present invention discloses a method for preparing a wire mesh, including the following steps: rolling the woven wire mesh to cause the wire mesh to undergo transverse and / or longitudinal deformation. This invention performs a rolling process (secondary processing) on ​​the woven wire mesh, making the surface of the wire mesh flatter and smoother. Due to the deformation caused by the pressing, the mesh spacing is reduced, and the unit area mass of the same mesh size is reduced. At the same time, the deformation at the warp and weft overlap position is large, and the wire is not easy to shift, further enhancing the stability of the wire mesh.

[0011] It is understandable that the rolling process uses twin-roll rolling, hydraulic press pressing, or single-roll pressing.

[0012] The advantages of this invention compared to existing technologies are mainly reflected in: Quality advantages: Before rolling, the wire has a circular cross-section and a diameter of D. The mesh size between the wires is a length of a and a width of b. After rolling and deformation, the mesh size remains the same, but the wire cross-section becomes square due to deformation, with the length becoming L and the width becoming W. If the lateral deformation of the wire is 10%, the amount of wire required per unit area in the lateral direction is reduced by 10%, and the mass per unit area is reduced by 10%. For the same specification of wire mesh, this method saves at least 10% in cost. Advantages of specific surface area: When wire mesh is used as an electrode mesh, surface treatment is required, including spraying catalyst powder. Assuming the wire mesh diameter is D, the powder deposition rate during spraying is highly dependent on the incident angle. If the incident angle is 30° to the substrate surface, the spraying efficiency drops to 50% of that at a 90° incident angle. According to comprehensive calculations, the amount of powder used in spraying onto the rolled wire mesh is reduced by 30%, and the coating bonding strength is significantly higher than that of untreated wire mesh.
