The PVC composite material industry to maintain sustained growth momentum in the global financial crisis, the state industrial policies to guide and support the ten industry restructuring and revitalization, launched the emerging market of PVC composite materials. The market around the low carbon economy, the traditional environmental protection energy-saving emission reduction under the large-scale development and utilization of wind energy, energy structure adjustment, the emergence of new economic growth point of FRP composite materials application.
PVC plastic pipe production line is composed of control system, extruder, die head, setting cooling system, traction machine, planet cutting device and turning rack. Each pipe production line has two extrusion machines, the main one extruder using a strong conveyor liner and efficient screw, and another smaller extruder for extrusion line.
For the cylindrical sleeve, the stability of water into water ring and uniformity directly affect the quality of the extruded pipe, and the cooling rate of the molten material in the sleeve of the inner wall of the pipe can directly affect the quality of. Flake combined sizing set mainly for high speed extrusion of small diameter, PVC plastic pipe production line, applicable scope: 20, Phi Phi 63MM, according to the pipe diameter and the processing of different materials, the extrusion speed can reach 35M/MIN or higher. Sheet shaping device of multilayer thin copper plate, the middle diameter hole, is fixed by the support column. The distance between each layer of thin copper sheet according to the following rules: the blank into the direction of distribution. Distance increases, near the end of copper into the blank, the smaller the distance between, is still in the blank state in order to prevent the accumulation of plasticization and extrusion between the sheets, with the formation of surface hardening layer of copper pipe, can gradually increase the distance between.
