Description
Technical field
The utility model is related to PE-RT tubing technical fields, and in particular to a kind of five-layer co-squeezing resistance oxygen Sun-shading type PERT pipes.
Background technology
PERT is due to the design of its molecular structure so that PERT tubing is in high-temperature capability, creep-resistant property, thermal expansion system
The aspects such as number are more projected, and flexural property is excellent, and construction is easy, simultaneously because its have in price compared with tubing such as PB significantly excellent
Gesture so that its application amount is quite big.But common PERT tubing, in system operation, the oxygen content in system can be higher, this
It is do not possess prevention permeability energy due to this tubing itself, especially after tubing is heated, intermolecular distance becomes big, oxygen
Molecule is easily advanced into pipe-line system, causes water oxygen level in tubing higher, and in finally running in systems, oxygen is accelerated
The oxidation of metal parts and aging, the shortening system service life of plastic conduit.Further, since the entrance of oxygen and the pipe
Material not shading so that the growth of tube environment appropriate bacterial itself, after operation a period of time, in pipe, bacterium grows such tubing
Raw situation is serious, affects discharge and drinking water hygiene.
But be directed to the deficiencies in the prior art, developer be necessary to develop a kind of reasonable in design, simple structure, can be effective
Prevent the infiltration of PE-RT tubing oxygen, shield lights from effectively can avoid causing algae infestation in the inside of PE-RT tubing
Situation five-layer co-squeezing resistance oxygen Sun-shading type PERT pipe.
Utility model content
The purpose of this utility model is the shortcoming and defect in order to overcome prior art, there is provided reasonable in design, simple structure,
Can effectively prevent the infiltration of PE-RT tubing oxygen, shield lights from effectively can avoid causing in the inside of PE-RT tubing
A kind of five-layer co-squeezing resistance oxygen Sun-shading type PERT pipes of the situation of algae infestation.
A kind of five-layer co-squeezing resistance oxygen Sun-shading type PERT pipes, including internal layer, intermediate layer and outer layer；In the intermediate layer is coated on
The outside of layer, outside of the external sheath in intermediate layer be provided with the first tack coat between internal layer and intermediate layer, intermediate layer with outer
The second tack coat is provided between layer.
Further, the internal layer is PERT layers, and intermediate layer is EVOH（Ethylene-vinyl alcohol copolymer）Barrier layer, outer layer
For Sun-shading type PERT layers.
Further, first tack coat and the second tack coat are PUR.
Further, EVOH is coated with the outside of the outer layer.
The beneficial effects of the utility model are:
1. internal layer is PERT layers, with preferably heat-resisting croop property, is further able to effectively improve the steady state pipe
Sanitation performance, intermediate layer are EVOH barrier layers, act primarily as resistance oxygen effect, and outer layer is Sun-shading type PERT layers, and the layer is by adding one
The light-proofness material for determining concentration makes which possess shading performance, thermo oxidative aging and anti-light the first tack coat of oxygen aging function and second
Tack coat is PUR, ensure that adhesive strength substantially decay to the PERT pipes does not occur at high temperature, has ensured between each layer
Adhesive strength, be coated with EVOH on the outside of outer layer, possess thermo oxidative aging and anti-photooxidative aging performance, can effectively reduce
The photooxidation resistance speed of steady state pipe, has further ensured the service life of the PERT pipes；
2. the intermediate layer of resistance oxygen effect and the outer layer of shading performance are had by the external sheath in internal layer so as to more
Excellent antiseepage oxygen performance, shading performance, thermo oxidative aging and anti-light oxygen aging function, can effectively prevent bacteria breed, so as to
Reduce the loss of discharge, it is ensured that drinking water hygiene.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In accompanying drawing：100th, internal layer, the 200, first tack coat, 300, intermediate layer, the 400, second tack coat, 500, outer layer.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to embodiment：
As shown in figure 1, a kind of five-layer co-squeezing resistance oxygen Sun-shading type PERT pipes, including internal layer 100, intermediate layer 300 and outer layer
500；Intermediate layer 300 is coated on the outside of internal layer 100, and outer layer 500 is coated on the outside in intermediate layer 300, in internal layer 100 and centre
The first tack coat 200 is provided between layer 300, and the second tack coat 400 is provided between intermediate layer 300 and outer layer 500.
Internal layer 100 is PERT layers, and intermediate layer 300 is EVOH（Ethylene-vinyl alcohol copolymer）Barrier layer, outer layer 500 are screening
Light type PERT layer；First tack coat 200 and the second tack coat 400 are PUR, and the outside of outer layer 500 is coated with EVOH.
The above is only preferred embodiment of the present utility model, it is noted that for the ordinary skill people of this area
Member for, on the premise of without departing from the utility model know-why, some improvements and modifications can also be made, these improvement and
Retouching should also be as being considered as within protection domain of the present utility model.
