1) Standard 5-layer sinter mesh & filters

The standard five-layer sintered mesh structure is divided into four parts: a protective layer, a filter layer, a dispersion layer and a skeleton layer.

Both uniform and stable filtration accuracy and high strength and stiffness, high pressure strength requirements and filtration accuracy

The requirement for uniformity is an ideal filter material.

The standard 5-layer sintered mesh has a filtration mechanism of surface filtration and a smooth mesh channel, so it has excellent backwash regeneration performance and can be used repeatedly for a long time. It is especially suitable for continuous and automated operation. It is any kind of filter material. Can not be compared.

The material is easy to shape, process and weld, and can be processed into various types of filter elements such as a circular shape, a cylindrical shape, a cone shape, and a corrugated shape.

Characteristic:

• Good strength, good rigidity: high mechanical strength and compressive strength, good processing, welding and assembly performance, easy to use;
• Uniform and stable accuracy: uniform filtration performance for all filtration accuracy, in use.The mesh does not change;

2) Multi-layer metal sintered mesh

The multi-layer metal sintered mesh process is a special laminate press and vacuum sintering, characterized by high strength and overall rigidity.

Multi-layer metal sintered mesh is a new type of filter material with high strength and overall rigidity, which is made of multi-layer metal woven wire mesh and processed by special lamination pressing and vacuum sintering. The meshes are interlaced to form a uniform and ideal filter construction. It not only overcomes the shortcomings of low strength, poor rigidity and unstable mesh shape of ordinary wire mesh, but also can reasonably match and design the gap size, permeability and strength characteristics of the material, so that it has excellent filtering precision. Filtration resistance, mechanical strength, wear resistance, heat resistance, cold resistance and workability, filtration with high pressure resistance requirements and uniform filtration accuracy are ideal, and are widely used in petrochemical, nuclear power, synthetic fiber, film, Food, pharmaceutical, aerospace and environmental protection industries.

Main purpose multi-layer metal sintered mesh:

• Used as a dispersion cooling material in extremely high temperature environments;
• Used for gas enrichment fluidized bed orifice material;
• For high precision, high reliability high temperature filter materials;
• For high pressure backwash oil filters.

3) Punching plate sintered mesh

The perforated plate sintered mesh & filters is a sintered mesh in which a perforated plate and a base flat woven mesh are sintered together. The punching plate can be selected to have different thicknesses as needed, and the flat woven mesh can be one or more layers. The composite mesh has high compressive strength and mechanical strength due to the support of the punching plate. The two are sintered together to have both good gas permeability of the plain weave and mechanical strength of the perforated plate. Can be processed into a cylindrical, disc-type, chip cone filter. Widely used in water treatment, beverage, food, metallurgy, chemical and pharmaceutical industries.

• Good strength: Because of the fourth and fifth layers for support, it has high pressure resistance and mechanical strength;
• Easy to clean: Due to the use of surface filter material, it is easy to clean, especially suitable for backwashing;
• High temperature resistance: can withstand high temperatures of 480 ° C;
• Corrosion resistance: high corrosion resistance due to the use of SUS316L material;
• Easy to process: suitable for cutting, bending, stamping, stretching, welding and other processing conditions.

4) Sintered metal powder filter

The metal powder sintered filter element can realize micro-scale precision filtration, which can separate solid particles in liquid and gas. When the fluid passes through a certain precision filter element, the impurities are blocked on the surface of the filter element to form a filter cake, and the pure fluid flows out through the filter element. The contaminated or contaminated fluid is cleaned to the state required for normal production to ensure that the downstream unit obtains a clean product or protects the equipment from normal operation.

Different from the non-metal sintered filter element, when the filter cake on the surface of the sintered metal powder filter core reaches a certain thickness, due to its high strength performance characteristics, the filter element can be backwashed or backflushed by a certain reverse pressure. Clean the filter element so that the filter element can be used again.
