High Strength 5 Layer Sintered Stainless Steel Wire Mesh

The high strength 5 layer sintered stainless steel wire mesh is a porous metal material made of five-layer stainless steel wire mesh stacked and sintered at high temperature. It has high filtration accuracy, good mechanical strength and corrosion resistance, and is widely used in various industrial filtration, catalyst support, gas and liquid filtration and other fields.

The production process of the high strength 5 layer sintered stainless steel wire mesh involves stacking five layers of stainless steel wire mesh of different specifications or types together according to a specific structure, and then making it through sintering, pressurizing, rolling and other processes. This material is generally divided into five parts: protective layer, filter layer, separation layer, reinforcement layer, and support layer, each layer plays a specific role.

Physical characteristics

The physical characteristics of high strength 5 layer sintered stainless steel wire mesh mainly include:

1. Filtration accuracy. Due to its multi-layer structure and uniform pore distribution, it can provide high filtration accuracy, generally up to 1-200 μm.

2. Mechanical strength. The sintering process enhances the strength of the material, enabling it to withstand high pressure differences, with tensile strength up to 10-50 MPa.

3. Corrosion resistance. Due to the use of stainless steel, it has good corrosion resistance and is suitable for a variety of corrosive environments.

4. Thermal stability. Can maintain stable performance over a wide temperature range, with a maximum operating temperature of 800°C.

5. Porosity. The porosity of the sintered mesh is high, usually between 40 and 60%, which makes it have good permeability and flow capacity.

Parameters

Application field

The high strength 5 layer sintered stainless steel wire mesh is widely used in the following fields due to its excellent performance:

1. Automotive industry. Used in the manufacture of catalyst supports and supports in automobile exhaust purifiers.

2. Chemical industry. As a catalyst support, it provides a stable catalyst bed in chemical reactions.

3. Oil and gas. Used to separate and filter impurities during the production and processing of oil and gas.

4. Water treatment. Removal of suspended solids and contaminants in municipal and industrial water treatment.

5. Food and medicine. Used in the food processing and pharmaceutical industries to ensure product purity and hygiene.

6. Air filtration. Used for air filtration in HVAC systems, cleanrooms, and other environments.

Production process

The production process of the high strength 5 layer sintered stainless steel wire mesh requires strict requirements to ensure the quality and performance of the final product. The following are its basic production steps:

1. Select raw materials. Choose different specifications or types of stainless steel wire, usually including 304, 316L and other materials.

2. Woven into a mesh. The stainless steel wire is made into a wire mesh through a weaving process, and the mesh number (pore size) of each layer of wire mesh is different to meet different filtration requirements.

3. Laminated assembly. Stack five layers of wire mesh together in a specific order to form a laminated structure.

4. Preforming. Place the stacked wire mesh into the mold for preforming to ensure stability during the sintering process.

5. Sintering. The preformed structure is placed in a sintering furnace and heated to a high temperature (usually above 1000°C) in a vacuum or protective atmosphere, causing the metal surface to melt and fuse with each other to form a whole.

6. Cooling and post-processing. After sintering is completed, the sintered body is slowly cooled and necessary post-processing is carried out, such as shaping, polishing, etc.

Cleaning and regeneration

The high strength 5 layer sintered stainless steel wire mesh may be blocked by filtered impurities after a period of use, thus affecting its filtration effect. At this time, the sintered mesh needs to be cleaned and regenerated. Common cleaning methods include:

- Backwash. Use water or gas to rush into the sintering net from the opposite direction to wash away attached impurities.

- Ultrasonic cleaning. Utilize the shock generated by ultrasonic waves to peel and remove impurities.

- Chemical cleaning. Use the appropriate chemical reagent to dissolve or loosen the dirt attached to the sintered net.

With these cleaning methods, the standard five-layer stainless steel sintered mesh can restore its filtration performance and achieve reuse, thus reducing the cost of replacing the filter material.
