The three-layer and five-layer composite materials have strong hydrophobic properties and very good non-adhesive properties, so it is easy to remove the dust accumulated on the surface of the material, and can be rinsed with water to restore the performance, thereby enabling reuse, which also extends the time The service life of the equipment is long, and the material has undergone high-temperature heat setting treatment, and the microporous structure is very stable, thus effectively ensuring that dust particles can be effectively intercepted under high wind speeds.
