Abstract
The utility model discloses a functional polyethylene pipe. The pipe is of a bilayer structure, wherein an outer layer and an inner layer are bonded together, and the pipe is provided with a heat conducting layer serving as the inner layer. The polyethylene pipe prepared according to the utility model is good in heat-conducting property, and meanwhile, various physical property indexes of the polyethylene pipe are in accordance with corresponding national and industrial standards on PE type pipeline products in the fields of ground source heat pumps, floor heating and the like.
Description
Technical field
The utility model relates to a kind of polyvinyl piping materials field, relates in particular to a kind of functional polyvinyl piping materials.
Background technique
Advantage such as polyethylene pipe has that corrosion resistance is strong, wholesomeness good, pliability is good, light weight, shock resistance are good is widely used in plumbing and heat exchange, heating pipe system field.Yet as a kind of polymer material, the capacity of heat transmission of polyvinyl piping materials is very low with respect to metal tube, thus polyethylene pipe when being applied in heat exchange, field of heating its heat exchange efficiency lower.The capacity of heat transmission that improves polyvinyl piping materials can improve the heat exchange efficiency of buried heat exchange pipeline, heating pipe; Practice thrift pipeline materials and energy consumption; Reduce system cost, help the broader applications of polyvinyl piping materials in heat exchange field of heating such as earth source heat pump, floor heatings.
To the low deficiency of plastic article thermal conductivity, can be through changing the processing technique of material, concrete is exactly that research through molecular chain orientation and crystallization aspect improves the thermal conductivity of material under process conditions necessarily, but this method effect is limited.The most frequently used method is to improve the thermal conductivity of plastic article through the composite modification technology of plastics at present.Big quantity research shows to have only when adopting filling-modified method when heat filling content and reaches some that the thermal conductivity of material just can be significantly improved when filler formed the heat conduction network chain in matrix.And could form the heat conduction network chain when often needing high level when adopting single filler; But too much filler can greatly reduce mechanical property, compression resistance, moulding processability of material etc.; Thereby cause the polyvinyl piping materials performance, particularly long-term hydrostatic test can't reach the requirement of standard.
The model utility content
The utility model has overcome deficiency of the prior art, and a kind of functional polyvinyl piping materials is provided, and on the basis that keeps the original advantage of polyvinyl piping materials, has effectively improved the heat-conducting property of tubing.
In order to realize above-mentioned purpose, adopt following technological scheme: a kind of functional polyvinyl piping materials, said tubing are double layer construction, and outer and internal layer adheres to each other.Skin is a protective layer, and tubing is shielded, and internal layer is the tubing main body.
Said tubing is provided with heat-conducting layer, and heat-conducting layer is an internal layer, and internal layer is the tubing main body, plays the effect of tubing heat conduction again, makes tubing have good heat-conducting.
In the such scheme, the thickness of said heat-conducting layer is 0.2-0.5mm.
Compared with prior art, the polyvinyl piping materials of the utility model preparation has good heat-conducting, and its various physical performance indexs meet the country and the industry standard of PE class duct products in the fields such as corresponding earth source heat pump, floor heating simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
The structure of the utility model is as shown in Figure 1, comprises the protective layer of skin 1 and the heat-conducting layer of internal layer 2.Outer 1 to be used to protect the tubing main body of internal layer to be difficult for impaired, and the tubing main body of internal layer 2 plays the effect of heat conduction simultaneously, makes the heat-conducting property of tubing more excellent, and the thickness of internal layer 2 is generally 0.2-0.5mm.
Claims (2)
1. a functional polyvinyl piping materials is characterized in that, said tubing is double layer construction, and outer and internal layer adheres to each other, and said tubing is provided with heat-conducting layer, and heat-conducting layer is an internal layer.
2. functional polyvinyl piping materials according to claim 1 is characterized in that, the thickness of said heat-conducting layer is 0.2-0.5mm.
