Introduction:
The polyester spiral filter screen adopts advantages of high viscosity polyester chip wire, which is formed, woven, sorted, and shaped. It has a relatively fine and uniform mesh, which can block the leakage of small objects The filling material can be added in the middle of the spiral dry mesh to reduce air permeability, compact the mesh, reduce material loss on the mesh, and increase the lateral stiffness of the mesh. And can control the breathability by filling the mesh according to user needs.
Application:
Polyester Spiral Press Filter Fabrics are mainly used in paper making, printing and dyeing, food, and solid liquid separation industry. Also used for sludge dewatering, pulp washing, coal washing, chemical industry, wine bran dewatering, and other industries for pressure filtration. It is better used in high permeability areas of paper machine drying. It is also convenient to use, has a long lifespan, and is easy to repair.
