Embodiment Construction
[0020] The audio-frequency super-amphiphobic mesh composite film of the present invention is a compound of three-layer structure, the middle support layer is audio-frequency mesh, and the fiber layer and the super-amphiphobic layer are respectively distributed on both sides of the support layer.
[0021] The audio mesh is selected from the dust-proof mesh in the acoustic field used in the market. It is made of monofilament warp and weft through precision weaving. It has stable mechanical stability and can keep the warp and weft constant, the shape and size of the mesh aperture Invariant, this essentially non-deformable property is very important to maintain the mechanical stability of the composite structure. The selected audio mesh can be made of PET, PA, PP, PBT, PE, PEN, PEEK, cotton or several blends. The diameter of warp and weft is 10-150 microns, preferably 30-90 microns. The opening size is 10-300 microns, preferably 100-200 microns.
[0022] It should be pointed out...
