▎ 摘　　要

NOVELTY - Biaxial orientation crystalline polymer continuous processing forming device comprises pipe extruding machine, extrusion machine head (2), first-level cooling sizing box, first traction machine, a re-heating environment box (5), a core rod, a multi-stage temperature control conical orientation device (7), a secondary cooling and sizing box and a second traction machine. The extruder head is provided with extrusion die and extrusion core die. USE - The biaxially oriented crystalline polymer continuous processing forming device is useful in plastic pipe production, processing field, building water supply and drainage, gas conveying, electric telecommunication protection and agricultural irrigation field. ADVANTAGE - The biaxial orientation crystalline polymer continuous processing forming device has excellent high strength, light characteristics, corrosion resistance, low temperature flexibility and wear resistance, and strong adhesion to metal material e.g. steel material, and prevents the pipe blank in the expanding process caused by the deformation ability is reduced in advance damage problem, reduces the waste product rate in the production process, improves the pipe diameter expansion ratio, greatly improving the pipe wall molecular orientation degree, obviously improving the pressure resistance of the pipe, and realizes the structure of the orientation structure with more efficient melt processing greatly improving pipe ring direction/axial strength and compressive strength. The polyurethane/polytetrafluoroethylene-graphene nano-composite coating has good corrosion resistance and low-temperature flexibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a continuous processing forming of double-axis oriented crystalline polymer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the biaxially oriented crystalline polymer continuous processing.
