This extrusion line consists of Feeding system ,SJ-120/35 single screw extruder ,SJ-45/30 co-extruder ,Hydraulic screen changer, melt-pumps, feedblock, T-die, T-die frame,vacuum calibrating table, first haul-off machine, oven, second haul-off machine, Protective film covering unit, transverse cutting machine, electronic control system.
Characteristics of vacuum calibrator:
1.The hollow corrugated sheet extrusion machine using high-speed energy-saving stable screw, output increased by more than 25% compared to similar products
2. Special harden treatment and non-sticky coating on the surface.
4. Consist of vacuum sealing edge device.
5. High quality mould steel or high strength Al-Mg Alloy
6. Special design calibrating device, each individual control;
7. Specific temperature control device, reduce heat shrinkage, simple operation.
8.The technology of hollow sheet die with co-extrusion feed block to get UV+PC+UV, UV+PC hollow sheet can save 30% UV on the surface.
Application:
PC hollow sheet is a high-tech, comprehensive performance is extremely excellent, energy saving and environmental protection plastic sheet, is currently widely used in the international plastic building materials, is a high degree of transparency,
PC hollow sheet is widely used in commercial, factory, stadium lighting ceiling and sun awning, agricultural greenhouse, aquaculture and flower greenhouses, as well as telephone booths, news stand, station and other public facilities, advertising decoration, ring shield of bus station/garages/pergolas/corridors field.
