Abstract
The utility model discloses a double-layer coextrusion polrvinyl chloride composited tube, consisting of a polrvinyl chloride flexible outer layer, a polrvinyl chloride flexible inner layer and a polrvinyl chloride rigid middle layer. The double-layer coextrusion polrvinyl chloride composited tube is characterized in that the polrvinyl chloride rigid middle layer is added between the polrvinyl chloride outer layer and the polrvinyl chloride inner layer, and the three layers are tightly combined and are connected with a composited tube by adopting a hot melting butt joint mode. Compared with a common polrvinyl chloride tube stock, the double layer coextrusion polrvinyl chloride composited tube improves the physical and mechanical performance by 30 percent, and has high compression and impact resisting strength.
Description
Technical field
The utility model relates to a kind of water pipe of PVC, particularly a kind of double-layer coextrusion PVC composite pipe.
Background technique
Polyvinyl chloride pipe is main raw material with the Corvic, adds appropriate amount of addition agent, through extruding and moulding, is mainly used in architectural drainage system and cable cover(ing) engineering.China pays much attention to build a conservation-minded society, present energy-conservation task is very heavy, that the plastic pipe of using should have is energy-conservation, economize on water, save land, " four joints " characteristics of material-saving, China rural area also has 3.2 hundred million people to be in the drinking-water unsafe condition, will drop into huge fund aspect national construction in many municipal treatment plants, the drainage pipeline networks construction in the coming years.And the middle water yield of 2010 yearly plan reuse of wastewater will reach 30% of sewage total amount, needs special transportation pipe road, also need increase the middle grid design of reusing sewage in the building.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of double-layer coextrusion PVC composite pipe, improves the toughness and the rigidity of tubing, is applicable to the enforcement of various places, and long service life does not impact environment.
The utility model is to realize by following technological scheme:
A kind of double-layer coextrusion PVC composite pipe, form by PVC pliant outer layer, PVC toughness internal layer and PVC rigidity mesosphere, between PVC skin and PVC internal layer, add PVC rigidity mesosphere, combine closely for three layers, and adopt the hot melt docking mode to connect composite pipe.
The beneficial effects of the utility model are:
(1) pvc material is recyclable utilizes again, can not exert an influence to environment;
(2) tubing light weight durable (density be steel pipe 1/5), need not machinery can easily carry, and reduces labor intensity greatly and shortens construction period;
(3) compare with common polychloroethylene pipes, physical and mechanical properties improves 30%, resistance to compression, excellent in cushion effect;
(4) corrosion-resistant, ageing-resistant, long service life.(utilization rate is limited to 30-50);
(5) good flame resistance, pvc material have from fiery self-extinguish ability energy.(oxygen index 〉=40);
(6) resistance is little, and the tubing inside and outside wall is smooth, and fluid resistance is little, improves 30% than the iron pipe flow;
(7) insulating property are strong, can bear high voltage and not breakdown, make cable sheath tube and use and can effectively avoid electric leakage, electric shock accidents.
Description of drawings
Fig. 1 is the structural drawing of double-layer coextrusion PVC composite pipe
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, it is the structural drawing of double-layer coextrusion PVC composite pipe, by PVC pliant outer layer 1, PVC toughness internal layer 2 and PVC rigidity mesosphere 3, between PVC outer 1 and PVC internal layer 2, add PVC rigidity mesosphere 3, combine closely for three layers, and adopt the hot melt docking mode to connect composite pipe.
The utility model mainly is the shared ratio difference of the PVC of three-decker, wherein PVC pliant outer layer 1 and PVC toughness internal layer 2 are to extrude simultaneously in extruder, its composition is roughly the same, can be according to the place difference of implementing, the content of PVC in the PVC pliant outer layer 1 is improved, thereby improve its toughness; Add PVC rigidity mesosphere 3 afterwards, add the working life that this layer can increase tubing.Combine closely for three layers, and adopt the hot melt docking mode to connect composite pipe.Can be used for industries such as sewage treatment, combustion gas, heating, city non-excavating construction, communication, mine.
