Production line of three-layer composite drip irrigation belt Blowing machine using dual-layer coextrusion spiral die, the distribution of the material layer ABA (A represents a new material, B represents the old material). Material flow under the action of the screw, the molecular chain is stretched in a spiral direction and the diameter direction fusion material is biaxially stretched after further improve their physical properties.
The glass fiber reinforced pipe with strong rigidity and toughness to withstand high internal pressure and external pressure the ability to make plastic PP, PE characteristics play better, to overcome the long pipe will be bent or deformed when weaknesses, is malleable pipe has a very strong and tough.

DGD-1603 Production line of three-layer composite drip irrigation belt or other equipments is in your interesting, please contact us for more details
