Abstract
The utility model discloses a kind of oxygen-resistance type three type polypropylene pipes, the skin of described tubing is PPR layer, and mesosphere is ethylene-vinyl alcohol copolymer oxidation prevention layer, and internal layer is interior PPR layer.It is co-extruded by PPR layer, ethylene-vinyl alcohol copolymer oxidation prevention layer, interior PPR layer; And the material of main part structure of molecule of each layer is similar, without tackiness agent, can realize good compatibility.This tubing not only has good resistance oxygen effect, prevents that intrasystem metal partial corrosion from getting rusty, and can realize inwall non-scaling, be difficult for layering, breed bacteria and algae, do not make water quality health more, be applicable to the cool and hot water pipe under various environment, be easy to apply.
Description
Technical field
The utility model relates to the technical field of macromolecule composite pipe, specifically a kind of oxygen-resistance type three type polypropylene pipes, the particularly composite structure of tubing.
Background technique
Although hot and cold water has high temperature resistant, high pressure resistant, corrosion-resistant, convenient transportation, is easy to the advantages such as installation, also Shortcomings with plastic tube.Eighties of last century beginning of the eighties, European technician finds: while applying plastic tube in heating system, in system, metal parts is oxidizable, perishable.This be because common plastic tube can not blocking oxygen infiltration, and oxygen is conducive to some bacterium and microbial growth, make the inner bacterium of tubing and microorganism amount reproduction, form gradually biological clay, causing tubing inner fluid to carry not smooth, even there is blocking phenomenon in pipe with small pipe diameter; The continuous infiltration of oxygen simultaneously also can cause tubing and other relevant device losts of life, so plastic tube oxygen resistance quality is directly connected to application performance and the working life of tubing.
Summary of the invention
The purpose of this utility model is to provide a kind of oxygen-resistance type three type polypropylene pipes, by complex method, in tubing wall, add one deck oxidation prevention layer, by the effect of oxidation prevention layer, after tubing is installed and used, the oxygen of air cannot infiltrate, and effectively prevents that intrasystem metal partial corrosion from getting rusty.
To achieve these goals, the technical solution of the utility model is: a kind of oxygen-resistance type three type polypropylene pipes, it is characterized in that: the skin of described tubing is PPR layer, and mesosphere is ethylene-vinyl alcohol copolymer oxidation prevention layer, internal layer is interior PPR layer.
The utility model discloses a kind of oxygen-resistance type three type polypropylene pipes, it is co-extruded by PPR layer, ethylene-vinyl alcohol copolymer oxidation prevention layer; And the material of main part structure of molecule of each layer is similar, without tackiness agent, can realize good compatibility.This tubing not only has good resistance oxygen effect, prevents that intrasystem metal partial corrosion from getting rusty, and can realize inwall non-scaling, be difficult for layering, breed bacteria and algae, do not make water quality health more, be applicable to the cool and hot water pipe under various environment, be easy to apply.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein:
1, PPR layer;
2, ethylene-vinyl alcohol copolymer oxidation prevention layer;
3, interior PPR layer.
Embodiment
With reference to the accompanying drawings, the utility model is further described.
The utility model is a kind of oxygen-resistance type three type polypropylene pipes, and it is different from prior art and is: the skin of described tubing is PPR layer 1, and mesosphere is ethylene-vinyl alcohol copolymer oxidation prevention layer 2, and internal layer is interior PPR layer 3.
PPR layer 1 in resistance oxygen pipe adopts PPR and respective material blend, has higher impact resistance, and this layer thickness is the 50%-70% of tube wall total thickness, guarantees to install welding quality.
The thickness of oxidation prevention layer 2 is the 5%-20% of tube wall total thickness, the oxygen barrier material that adopts EVOH or be mixed, can infiltrate pipe-line system by blocking oxygen, thereby prevent that intrasystem metal partial corrosion from getting rusty, greatly extend the working life of the metalworks such as main metallic conduit, metal valve, switch, boiler, water collecting and diversifying device in whole system, even if water does not flow and also can not go bad because of oxidation for a long time; Meanwhile, the bacterium depending on for existence by oxygen also cannot grow.
Interior PPR layer 3 adopts pure PPR raw material, fully guarantees the high temperature resistant property of internal layer, and this layer thickness is the 10%-30% of tube wall total thickness.
In the specific implementation, the thickness of the thickness of described PPR layer 1 and oxidation prevention layer 2 and the thickness ratio of interior PPR layer are 3:1:2, utilize the characteristic of each layer, can promote to greatest extent intensity, resistance oxygen degree, the antibacterial index of pipe fitting.
In the specific implementation, described interior PPR layer inwall is covered with one deck Nano Silver Zinc ion layer.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that the concrete enforcement of the utility model is confined to above-mentioned these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
