High Air Permeability Multi-Layer Square Hole Sintered Mesh

The high air permeability multi-layer square hole sintered mesh is made by superimposing multiple layers of metal wire mesh (such as stainless steel wire mesh) and then processed by high-temperature sintering process. This process forms a strong metallurgical bond between the layers of wire mesh, which not only maintains the shape and size of the original mesh, but also greatly enhances the overall mechanical strength and corrosion resistance. Compared with round holes or holes of other shapes, the square hole structure can provide a more uniform filtering effect and higher flow capacity. Because of the high opening rate of the square hole mesh, the sintered mesh made has the characteristics of high air permeability, low resistance and large circulation.

 

Structural characteristics

The core of the high air permeability multi-layer square hole sintered mesh lies in its unique "multi-layer" and "square hole" design. First of all, "multi-layer" means that the filter is not a single layer structure, but is composed of several layers of metal wire mesh with different apertures. The aperture size of each layer is carefully designed to achieve a progressive filtering effect, that is, coarser impurities are intercepted by the first few layers, while finer particles are captured by subsequent denser mesh layers. This design not only improves the filtration accuracy, but also ensures good permeability, reduces pressure drop, and prolongs the service life.

 

Secondly, the "square hole" structure is a major feature that distinguishes it from traditional circular or irregular pores. The square hole design helps to reduce the resistance of fluid passing through while ensuring filtration efficiency, because the streamlines at the edges of the square holes are straighter, reducing the generation of eddies and thus reducing energy loss. In addition, the square holes are arranged more regularly, which is convenient for controlling the consistency of the aperture during the manufacturing process and ensuring the stability of the filtration effect.

 

Performance advantages

1. High filtration accuracy and efficiency

The multi-layer design can filter impurities of different particle sizes in a graded manner, ensuring extremely high filtration accuracy and efficiency.

2. High strength and durability

Production process

The production process of the high air permeability multi-layer square hole sintered mesh mainly includes several key steps: selection of wire mesh, stacking, positioning, high-temperature sintering and post-processing.

1. Wire mesh selection

According to application requirements, select suitable metal materials, such as stainless steel (commonly 304, 316L, etc.), monel alloy, titanium alloy, etc., which have good corrosion resistance and mechanical properties. The shape, size and number of layers of the mesh are customized according to the filtration accuracy requirements.

2. Stacking and positioning

The selected multi-layer wire mesh is precisely stacked in the designed order, and special positioning technology is used to ensure that the layers are aligned and fixed to prevent displacement during the sintering process.

3. High-temperature sintering

Put the stacked mesh into a special sintering furnace and heat it at high temperature (usually above 1000℃) to melt the contact points between the wire meshes and cool and solidify to form a metallurgical bond. This process not only strengthens the overall structure of the mesh, but also ensures the tight connection between the layers.

4. Post-processing

The sintered mesh needs to go through cutting, edge processing, surface cleaning and other processes to meet the specifications of the final product. Some products also need heat treatment or chemical treatment to further improve their corrosion resistance or specific physical properties.
