▎ 摘  要

NOVELTY - Mixed woven packing set comprises polytetrafluoroethylene fiber (2), titanium material (3), graphene layer, high carbon fiber layer, synthetic fiber layer, wear-resistant material (9) and packing main body, where the inner side of the packing main body is covered with the tetrafluoroethylene fiber, the inner side of the tetrafluoroethylene fiber is covered with the titanium material, the inner side of the titanium material is covered with a filler material (4), the graphene layer is provided on the inner side of the filler material and the graphene layer is covered with the high carbon fiber layer. A synthetic fiber layer is provided on the inner side of the high carbon fiber layer, where the inner side of the synthetic fiber layer is provided with the wear-resistant material, the surface of the packing main body is coated with a layer of a sealant layer (1) and the thickness of the sealant layer is 0.15 mm. USE - As mixed woven packing set. ADVANTAGE - The mixed woven packing set adopts the sealant layer which provides excellent sealing effect and prevents leakage, the polytetrafluoroethylene fiber which has high resilience, chemical resistance, low cold flow, high line speed, chemical stability, corrosion resistance, air-tightness and aging resistance, can resist particle crystallization medium and higher temperature and the titanium material provided in the main body of the packing which has high strength, low density, high temperature resistance and low temperature resistance. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural view of the mixed woven packing set. Sealant layer (1) Polytetrafluoroethylene fiber (2) Titanium material (3) Filler material (4) Wear-resistant material (9)
