Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a wear-resistant polyurethane screen. Background Art

[0002] Filter mesh, also known as filter mesh for short, is made of metal wire mesh with different mesh sizes. Its function is to filter the molten material flow and increase the material flow resistance, so as to filter out mechanical impurities and improve the mixing or plasticizing efficiency.

[0003] The current primary filter is made of glass fiber, synthetic fiber, metal wire mesh and coarse-pore polyurethane foam plastics, etc. Its pore size is large and uniform, and it can filter out large suspended particles, light long fibers and flocculent floating objects in the air.
