PVC membrane structure is generally composed of PVC membrane structure material membrane structure project, PVC membrane structure material is the membrane structure material used by general membrane structure company, PVC membrane structure material is made of membrane structure polyester fiber with PVC membrane structure material coating, it is coated with several micron thick membrane structure material acrylic resin (acrylic) on the surface treatment of PVC membrane structure material coating material to improve the dirt-proof property of PVC membrane structure material, to improve the service life of PVC membrane structure material, to improve the fire resistance of PVC membrane structure material and the strength of PVC membrane structure material. It is coated with acrylic resin of several micron thick membrane structure material on the surface treatment of PVC membrane structure material, in order to improve the anti-fouling property of PVC membrane structure material, increase the service life of PVC membrane structure material, improve the fireproof property of PVC membrane structure material, and also the strength of PVC membrane structure material.
