Abstract
The utility model relates to the tubing field, particularly to an oxygen-resistant heat-resistant tubing. The tubing comprises an oxygen-resistant layer, an adhesive layer and a high temperature resistant polyethylene layer from outside to inside, wherein the thickness ratio of the oxygen-resistant layer, the adhesive layer and the high temperature resistant polyethylene layer is 1: (12-13): (1-1.5). The oxygen-resistant layer blocks oxygen from permeating into water or air in the tubing, the service life of metal parts in the whole pipe system is greatly prolonged, corrosion to the metal parts in the system is delayed, scaling of the pipe system is reduced, and microorganisms in the system are effectively suppressed. The tubing is widely applied to cold and hot water pipe systems of buildings, floor heating systems and food processing industries.
Description
Technical field
The utility model relates to the tubing field, especially a kind of resistance oxygen heat-resisting pipes.
Background technique
Employed tubing not only need possess good hydrodynamic performance and pliability in fluid-transporting tubings such as the beverage of the pipeline potable water system of building and food industry, drinks, milk, also high temperature resistant, low temperature resistant, corrosion-resistant, inner wall smooth non-scaling and be difficult for breed bacteria.And the tubing of existing market does not also reach this requirement.
Summary of the invention
To the deficiency that existing tubing exists, the purpose of the utility model provides a kind of resistance oxygen heat-resisting pipes, effectively prevents metal parts corrosion and the interior bacteria breed of pipe in the pipe-line system.
For realizing above-mentioned purpose, the technological scheme that the utility model adopts provides a kind of resistance oxygen heat-resisting pipes, and it comprises oxidation prevention layer, adhesive layer, refractory polyethylene layer from outside to inside successively; Said oxidation prevention layer; Adhesive layer, the thickness proportion of refractory polyethylene layer are 1: 12～13: 1～1.5, said oxidation prevention layer; Adhesive layer, the refractory polyethylene layer is through plastic shaping extruder coextrusion mold.Preferred said oxidation prevention layer is the ethylene/vinyl alcohol copolymer layer.In addition, said oxidation prevention layer is added with blue colorant.
The beneficial effect of the utility model is that oxidation prevention layer has intercepted in the water or air in the oxygen infiltration tubing, prolongs the working life of metalwork in the whole tubing greatly, delays the corrosion of metal parts in the system, reduces the structure of pipe-line system.Sanitation performance is more superior than the tubing of other types, and oxidation prevention layer has stoped the microorganism infiltration of necessary oxygen of surviving, thereby has suppressed the existence of microorganism in the system.This tubing of while also has pliable and tough flexible, and hydrodynamic performance is good, and is corrosion-resistant, low temperature resistant, perfect heat-dissipating, excellent shock resistance, the advantage of long service life.
Description of drawings
Fig. 1 is the schematic cross-section of the utility model.
Embodiment
In conjunction with accompanying drawing 1 and embodiment the structure of the utility model is explained.
As shown in Figure 1; The utility model is followed successively by oxidation prevention layer 3 from outside to inside; Adhesive layer 2, refractory polyethylene layer 1, the thickness ratio of said oxidation prevention layer 3, adhesive layer 2 and refractory polyethylene layer 1 is 1: 12～13: 1～1.5; Trilaminate material is combined as a whole through plastic shaping extruder coextrusion mold, is added with blue colorant in the oxidation prevention layer 3.
Claims (2)
1. one kind is hindered the oxygen heat-resisting pipes; It is characterized in that: this composite pipe comprises oxidation prevention layer, adhesive layer and refractory polyethylene layer from outside to inside successively, and the thickness ratio of said oxidation prevention layer, said adhesive layer and said refractory polyethylene layer is followed successively by 1: 12～13: 1～1.5.
2. according to the resistance oxygen heat-resisting pipes described in the claim 1, it is characterized in that said oxidation prevention layer is the ethylene/vinyl alcohol copolymer layer.
