Description

Technical Field

[0001] The utility model relates to the technical field of metal powder sintering, in particular to a titanium powder porous felt plate. Background Art

[0002] Porous metal felt plate is a metal filter material with a porous structure made of industrial high-purity metal powder through processes such as powder classification, screening, molding, sintering, and mechanical welding. Due to its unique porous structure and efficient filtration performance, it is widely used in many industrial fields such as the pharmaceutical industry, water treatment industry, food industry, bioengineering, and chemical industry. In the chemical industry, porous titanium plates can be used to prepare efficient catalysts and reactors for chemical synthesis and separation operations. In the PEM hydrogen production process, titanium felt can be used as a plate, mainly used to support the membrane electrode and gas diffusion layer, while converging hydrogen and oxygen and conducting electrons.

[0003] Currently, titanium plates formed by sintering titanium powder are brittle in texture. When making large-area titanium plates, they are easily broken in the middle due to the influence of gravity, which affects the use of the titanium plates. Utility Model Content

[0004] In view of the above problems, the utility model provides a titanium powder porous felt plate.

[0005] In order to achieve the above-mentioned invention object, the technical solution adopted by the utility model is as follows:

[0006] A titanium powder porous felt plate is provided, comprising a support net and a titanium powder layer arranged on at least one side of the support net, wherein the support net is provided with a plurality of mesh holes filled with titanium powder, and the support net is made of pure titanium.

[0007] Furthermore, the support mesh is any one of a pure titanium woven mesh and a pure titanium cut and drawn mesh.

[0008] Furthermore, titanium powder layers are provided on both sides of the support mesh.

[0009] Furthermore, the titanium powder layer and the support mesh are formed and fixed by a sintering process.

[0010] Furthermore, a plurality of raised reinforcing ribs are arranged on the supporting net.

[0011] Furthermore, the reinforcing ribs are wavy in shape, and a plurality of reinforcing ribs are parallel to each other.

[0012] Furthermore, the reinforcing ribs are S-shaped, and a plurality of reinforcing ribs are staggered with each other.

[0013] The beneficial effects of the utility model are as follows: a support net made of pure titanium is built into the traditional titanium powder sintered titanium plate, so that the titanium powder is filled into the mesh holes in the support net. The sintered titanium plate has a higher structural stability than the traditional titanium plate through the support of the support net, and the production area of ​​the titanium plate can be made larger, longer and thinner. At the same time, the flexibility of the titanium plate is enhanced, and it can be slightly curled, which is convenient for winding the titanium plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Example 1

[0021] The present application embodiment discloses a titanium powder porous felt plate, referring to Figure 1 , including a support net 1 and a titanium powder layer 2, the titanium powder layer 2 is integrally fixed on one surface of the support net 1, a plurality of mesh holes 11 are formed through the support net 1, the mesh holes 11 are filled with titanium powder, and the support net 1 is made of pure titanium material.

[0022] The titanium powder layer 2 is composed of pure titanium powder. After the support mesh 1 and the titanium powder layer 2 are set, the mesh is combined and fixed to the titanium powder layer 2 through a sintering process. The porous structure of the titanium felt is maintained by the titanium powder layer 2, and the toughness of the titanium felt is enhanced by the support mesh 1, so that the titanium felt is not easy to break. Traditional titanium felt cannot be made into large-area flat plates. Usually, its length and width are less than 500mm, and in order to keep the flat plate structure from breaking, the thickness cannot be made thinner, and generally cannot be less than 0.5mm. After adding the support mesh 1, the area of ​​the titanium felt can be increased infinitely. According to the thickness of the support mesh 1 used, the thickness of the titanium felt can reach 0.1mm at the bottom. The titanium felt with the support mesh 1 is flexible and can achieve the bending of the titanium felt.

[0023] The support mesh 1 can be any one of a pure titanium woven mesh and a pure titanium cut and drawn mesh.

[0024] In the embodiment of the present application, a titanium powder layer 2 is provided on one side of the support mesh 1 .

[0025] Example 2

[0026] Reference Figure 2 The difference between Example 2 and Example 1 is that the number of titanium powder layers 2 is different.

[0027] In the embodiment of the present application, titanium powder layers 2 are provided on both sides of the support mesh 1, and the double-sided titanium powder layers 2 increase the number of pores on the surface of the titanium felt.

[0028] Example 3

[0029] Reference Figure 3 The difference between Example 3 and Example 1 is that a reinforcing rib 21 is provided on the supporting net 1.

[0030] In the embodiment of the present application, a plurality of raised reinforcing ribs 21 may be provided on the support mesh 1, and the reinforcing ribs 21 may be formed by rolling the support mesh 1. By sacrificing the thickness and flexibility advantages of the titanium felt, the reinforcing ribs 21 may be used to enhance the toughness of the titanium felt and the structural stability of the titanium felt.

[0031] In the embodiment of the present application, the reinforcing ribs 21 are wavy, and several wavy reinforcing ribs 21 are parallel to each other, and adjacent reinforcing ribs 21 overlap with each other in the length and width directions of the titanium felt, so that the titanium felt can maintain good structural stability in both directions.

[0032] Example 4

[0033] Reference Figure 4 The difference between Example 4 and Example 3 is that the shape of the reinforcing rib 21 is different.

[0034] In the embodiment of the present application, the reinforcing ribs 21 are S-shaped, and a plurality of reinforcing ribs 21 are staggered. Furthermore, the reinforcing ribs 21 on both sides of the adjacent titanium felt overlap each other in the length and width directions. By adopting the S-shaped reinforcing ribs 21, the deformation of the support mesh 1 is reduced, the titanium felt is kept flat, and the overall structural stability of the titanium felt is improved.

[0035] In other embodiments, the reinforcing ribs 21 may also be designed as other filling arrays of regular or irregular shapes, so that all horizontal straight lines on the support net 1 are covered by the reinforcing ribs 21 to enhance the supporting effect of the support net 1 on the felt board.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
