Knitted Mesh Interlock Structure Offers Good Filtration Performance

Knitted mesh is a continuous knitted mesh fabric produced by knitting metal wires on a circular knitting machine. This production process produces an extremely strong and flexible mesh fabric composed of a series of interlocking rings. It can be made of round or flat wires. The round wire knitted mesh is the most widely used type and the flat wire knitted mesh is used in special applications according to customers' requirements. It is widely used for gas-liquid filtration in the fields of petroleum, chemical industry, metallurgy, pharmaceuticals and for EMI shielding in the electronic field.

Knitted mesh can be made of stainless steel wires, copper wires, brass wires, galvanized wires, nickel wires and other alloy wires. It can also be made of PP, PTEF and other non-metallic wires and can be customized upon request.

Knitted mesh made of different materials are displayed.
Material

Stainless steel knitted mesh

Acid and alkali resistance, high temperature resistance

Copper knitted mesh

Corrosion resistance, reusable

PP knitted mesh

Better corrosion resistance, high strength

PP and stainless steel knitted mesh

Withstand extreme chemical conditions and good thermal stability

Wire Type

The round wire knitted mesh is the most widely used type and the flat wire knitted mesh offers a larger contact area and an enhanced separation efficiency.

Strand Type

Knitted mesh can be made of single-strand wires or multi-strand wires. The single-strand knitted mesh is simple and economical and is widely used in general-purpose applications. Multi-strand knitted mesh is made by knitting 3–12 strands metallic or non-metallic materials with a wire diameter ranging from 0.1 mm to 0.3 mm with knitters. In addition to the characteristics of common knitted mesh, it has a larger surface area and higher strength, and is mostly used in heavy duty applications, for example, the filtration and separation in chemical and petrochemical industries.

Surface Type

Flattened surface is a standard surface type for general-purpose applications. When the knitted mesh is produced completely, it is ginned by special technology to form ginning in various shapes, widths and depths. It can be applied in a variety of industrial applications.
