Two-layer co-extrusion PE compound pipes in the plastic pipe material plays a very important position PE compound pipes adopt double co-extrusion compound technique for the performance will be with the minimum thickness of resin Into pipes, reduce the material cost of double machine co-extrusion; Through the different function of resin, just using a processing process can manufacture the multifunctional composite pipe into double, avoid the word more complex production working procedure, can reduce production cost; The resin with polarity through altogether crowded compound with heating plasticizing adhesion, production process no pollution, no solvent cementing, is environmental protection plastic pipe material; Producing the same specification of pipes that can greatly reduce the raw material plastication time, which greatly increase the production efficiency. Two-layer co-extrusion PE compound pipe equipment parts mainly include: the host, co-extrusion composite head, molding machine etc, which altogether Crowded compound nose, molding machine is decided to product quality and yield the key equipment. At the same time, the quality of the raw material is the main factor to determine the quality of products. Dual machine co-extrusion PE compound pipe process is as follows: the composition of Two-layer co-extrusion PE pipe production line: 1, SJ-65/25 single screw extruder 1set 2, SJ-45/25 single screw extruder 3sets 3, vacuum calibrating bench (material iron plate) 2sets 4, crawler tractor 1 set 5, automatic coil pipe bender (with four plates) 2 sets 6, compound mould |
