Abstract
The utility model discloses a kind of polyethylene water-feeding pipes, comprise supply pipe body, described supply pipe body, by internal layer and skin, is provided with the resistance to compression layer be made up of steel wire material between internal layer and skin, and is provided with oxidation prevention layer on described outer field surface; Described internal layer is white low-pressure high-density polyethylene layer, and described skin is hp-ldpe layer.Water-feeding pipes of the present utility model has that crushing resistance is strong, anticorrosive property good, the feature of long service life.
Description
Technical field
The utility model relates to a kind of conveyance conduit, is specifically related to a kind of polyethylene water-feeding pipes.
Background technique
Supply pipe is the device for water source conveying, indispensable in industry and residential construction.Water-feeding pipes in the market mainly contains PP-R pipe (three type polypropylene random copolymer pipes), PE pipe (polyethylene pipe) and PE-RT pipe (heat-resisting polyethylene tube).Wherein PP-R pipe is mainly used in a tubulature, and PE pipe is mainly used in the major trunk roads supply pipe introducing water source, and PE-RT pipe is mainly used in floor heating pipe.Above-mentioned several plastic tube all has melting characteristic jointly, and hot-melt adhesive paste is easy and sealing is reliable, and construction cost is low, and application is at home comparatively universal.But plastic tube exists the defect of oozing oxygen in actual using process, and increase along with the oxygen infiltration amount of the rising plastic tube of temperature, cause plastics acceleration " thermo-oxidative ageing ", while affecting quality of water supply, also shorten the working life of plastic tube like this.In addition, because plastic water supply pipe is laid in underground or in the environment exposed, continues to there will be for 3 months to about 1 year pipe leakage phenomenon service time or even occur the situation of pipeline breaking due to compressive resistance difference.
Model utility content
For above-mentioned deficiency, technical problem to be solved in the utility model is to provide the polyethylene water-feeding pipes that a kind of corrosion-resistant, excellent in cushion effect, impermeable work is made good use of.
For solving the problem, the utility model is achieved through the following technical solutions:
A kind of polyethylene water-feeding pipes, comprise supply pipe body, described supply pipe body, by internal layer and skin, is provided with the resistance to compression layer be made up of steel wire material between internal layer and skin, and is provided with oxidation prevention layer on described outer field surface; Described internal layer is white low-pressure high-density polyethylene layer, and described skin is hp-ldpe layer.
In such scheme, described oxidation prevention layer can be made up of EVOH material, and its thickness accounts for 1% ~ 3% of supply pipe body total thickness.
Compared with traditional PE supply pipe, the utility model has the advantages that:
1, supply pipe body of the present utility model is inside and outside two layers of polyethylene Rotating fields composition, is provided with the resistance to compression layer of steel wire material, makes the rigidity of tubing like this, shock resistance significantly improves between internal layer and skin;
2, the oxidation prevention layer be made up of EVOH material of the skin setting of supply pipe body, not only to gas, smell, perfume solvent etc., there is excellent blocking effect and the effect of resistance oxygen, but also there is very high mechanical strength, elasticity, rigid, the effect such as wear resistance, weathering resistance, can improve tubing corrosion resistance, extend working life of tubing.
Accompanying drawing explanation
Fig. 1 is the cross-sectional structure schematic diagram of this polyethylene water-feeding pipes.
Number in the figure is: 1, internal layer; 2, outer; 3, resistance to compression layer; 4, oxidation prevention layer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further explained illustrates, but not in order to limit the utility model.
As shown in Figure 1, a kind of polyethylene water-feeding pipes, comprise supply pipe body, described supply pipe body is by internal layer 1 and outer 2, described internal layer 1 is white low-pressure high-density polyethylene layer, for internal layer 1 directly contacts with transported water, for anti-sealing is polluted at tubing course of conveying and affects, described white low-pressure high-density polyethylene layer is not containing any additive; Described outer 2 is hp-ldpe layer.Between internal layer 1 and outer 2, be provided with the resistance to compression layer 3 be made up of steel wire material, and be provided with oxidation prevention layer 4 on the described surface of outer 2, further, described oxidation prevention layer 4 is made up of EVOH material, and its thickness accounts for 1% ~ 3% of supply pipe body total thickness.EVOH is also known as ethylene-vinyl alcohol copolymer; it is highly crystalline body; excellent blocking effect and the effect of resistance oxygen can not only be had to gas, smell, perfume solvent etc.; but also there is the effect such as very high mechanical strength, elasticity, rigid, wear resistance, weathering resistance, protection plastics are too early " oozing oxygen aging ".
When this water-feeding pipes makes, technique is compressing by co-extrusion machine co-extrusion routinely, and obtained polyethylene water-feeding pipes product wholesomeness is good, and its crushing resistance and anticorrosive property are improved and the working life of tubing extends.It can adopt electric smelting Placement when installing, and is applicable to municipal engineering, urban architecture feedwater, drinks the fields such as conveying.
