Description
Technical field
The present invention relates to a kind of tubing, be specifically related to a kind of plastic pipe and preparation method thereof.
Background technology
Plastic pipe is the chemical building material that high-tech is composited, and chemical building material is after steel, timber, cement, the fourth-largest class material of construction that the present age is emerging.In recent years, chemical building material has been obtained the rapid progress fast development in China, and especially being extensive use of of environmentally-friendly plastic tubing started the revolution of an alternative traditional construction material.Current losses is little, energy-conservation because having for plastic pipe, material-saving, protection ecology, the advantage such as convenient of being completed, and is widely used in fields such as building water supply and drainage, cities and towns plumbing and gas line at present, becomes the main force of new millennium urban construction pipe network.
Plastics are different with traditional material, technical progress paces faster, constantly new technology, novel material, the novel process that occurs makes the advantage of the relative traditional material of plastics tubing more and more outstanding.Plastic pipe is compared with cement pipe with traditional metal tube, have in light weight, general is the 1/6-1/10 of metal tube only, erosion resistance is preferably arranged, shock resistance and tensile strength, the plastics tubing internal surface than cast iron pipe smooth many, frictional coefficient is little, fluid resistance is little, can reduce the water delivery energy consumption more than 5%, synthesis energy saving is good, makes the right reduction by 75% of energy consumption, convenient transportation, install simply, reach 30-50 work-ing life.Polyethylene tube is very fast in the countries in the world development over nearly 10 years, and developed country has accounted for absolute advantage in feedwater field and combustion gas field using polythene pipe.Polyethylene tube not only is used for replacing traditional steel pipe, cast iron pipe etc. in a large number, is also replacing polyvinyl chloride pipe, and reason just is polyethylene tube technological innovation over nearly 10 years.Material has great progress on the one hand, and by the improvement of polyethylene polymerization production technique, the intensity of polyvinyl piping materials PP Pipe Compound has almost improved 1 times.Utilisation technology has new development on the other hand, for example need not excavate pipe trench in recent years, the technology that adopts the directional drilling method to lay polyethylene tube has been given full play to the superiority of polyethylene tube, makes traditional piping material be fit to adopt the occasion of this method not have competitive capacity at all.
