PVC multilayer composite pipe production line is mainly used for the production of PVC composite pipe. PVC composite pipe is a new type of composite drainage pipe.
The tube is three layer coextrusion composite drainage pipe, the outer wall of the hard PVC, to ensure enough strength of pipe and other physical properties, middle layer is by special formula of PVC, the relative density 0.7-0.9g/cm3. The layer structure for micro closed hole shaped. This particular structure, the use of the material mechanics, the principle of type I. Micro view can be observed in the interlayer is soft colloid, which not only has all the advantages of PVC pipe for the wall of the (empty), and heat insulation, sound insulation, shockproof, anti shock and light mass, low price etc. Is better than that of the solid wall tube characteristics. 1 light weight (0.9-1.2g/cm3), the price is low. 2 smooth inner wall, small friction coefficient, improve the fluid conveying efficiency. 2 high impact strength, the ring of steel is 3 times the ordinary PVC-U. 4 good weather resistance, can be used at -30 for -70, and the size of the pipe is good when the temperature changes. 5 special composite multi-layer structure, greatly improving the sound insulation performance of pipe. 6 self extinguishing performance is strong. 7 has excellent corrosion resistance. 8 to improve the service life of the pipeline is 4-7 times of ordinary pipeline. 9 the installation cost of the composite pipe is lower than that of the ordinary pipe, and its corrosion resistance, wear resistance, weather resistance, etc..
