Abstract
The utility model discloses a cross-linked polyethylene pipe with an oxygen-blocking layer, which belongs to the technical field of plastic pipes. The utility model comprises a cross-linked polyethylene pipe body, and is characterized in that the outer surface of the cross-linked polyethylene pipe body is coated with an adhesive layer, and the outer surface of the adhesive layer is coated with an oxygen-blocking layer. The cross-linked polyethylene pipe has excellent oxygen-blocking performance, thereby effectively solving the problems of serious oxidization and corrosion of metal parts in a heating system caused by oxygen permeation in a pipe.
Description
Technical field
The utility model belongs to the plastic tube technical field, is specifically related to a kind of crosslinked polyethylene pipe with oxidation prevention layer.
Background technique
The tubing of the current employing of China mainly contains used for galvanized tube in feedwater piping and gas pipe line, and pvc pipe is used for waste pipe and sleeve pipe, and copper pipe and Stainless Steel Tube are used for the water and heat provision pipe of senior building.As an industrial policy of country, widely popularize chemical building material, aspect plastic pipe, progressively replace original metal or other tubing trend that is inevitable with the plastic pipe of novel high-quality.
What give prominence to the most in the plastic tube is crosslinked polyethylene pipe.It is applied to ground heating system or conventional heating system widely.But existing crosslinked polyethylene pipe has certain oxygen that oozes, and along with temperature raises, it is more outstanding that it oozes oxygen.Thereby cause the oxygen content in the pipeline to increase along with the rising of temperature.Hot water temperature in crosslinked polyethylene pipe is above 40 ℃, ooze the oxygen rate greater than 0.1mg(Lday) time, will to heating system that crosslinked polyethylene pipe is connected in metal heater, metal valve, pipe fitting, radiator, water pump etc. produce heavy corrosion, shorten the working life of these parts greatly, thereby improved user cost.
Summary of the invention
Problem at the prior art existence, the purpose of this utility model is to design a kind of technological scheme with crosslinked polyethylene pipe of oxidation prevention layer is provided, this crosslinked polyethylene pipe oxygen resistance is good, can solve effectively because of oozing oxygen in the pipeline and cause the phenomenon that the metal parts severe oxidation corrodes in the heating system.
Described a kind of crosslinked polyethylene pipe with oxidation prevention layer comprises the crosslinked polyethylene pipe body, it is characterized in that coating on the described crosslinked polyethylene pipe outer surface of tube body adhesive layer is set, and coats on the adhesive layer outer surface oxidation prevention layer is set.
Described a kind of crosslinked polyethylene pipe with oxidation prevention layer is characterized in that described adhesive layer is the high temperature heat-fusing glue layer.
Described a kind of crosslinked polyethylene pipe with oxidation prevention layer is characterized in that described thickness of adhibited layer is 0.1-0.15mm.
Described a kind of crosslinked polyethylene pipe with oxidation prevention layer is characterized in that described oxidation prevention layer is an evoh layer.
Described a kind of crosslinked polyethylene pipe with oxidation prevention layer is characterized in that described oxidation prevention layer thickness is 0.1-0.15mm.
Above-mentioned a kind of crosslinked polyethylene pipe with oxidation prevention layer, simple in structure, reasonable in design, the oxidation prevention layer that adhesive layer is set on the crosslinked polyethylene pipe body and constitutes by ethylene-vinyl alcohol copolymer, become three-decker, more can prevent from effectively to ooze oxygen in the pipeline, reach the effect of resistance oxygen.When above-mentioned crosslinked polyethylene pipe is used for heating system, overcome the problem of oozing metal parts severe oxidation corrosion in the heating system that oxygen causes because of pipeline, reduced the user cost of heating system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-crosslinked polyethylene pipe body; The 2-adhesive layer; The 3-oxidation prevention layer.
Embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure, a kind of crosslinked polyethylene pipe with oxidation prevention layer comprises crosslinked polyethylene pipe body 1, coat on crosslinked polyethylene pipe body 1 outer surface adhesive layer 2 is set, adhesive layer 2 is the high temperature heat-fusing glue layer, the elevated temperature heat melten gel can be the NF.528(Mitsui), adhesive layer 2 thickness are 0.1-0.15mm.The effect of adhesive layer 2 mainly is with outer field oxidation prevention layer 3 and crosslinked polyethylene pipe body 1 bonding formation one.Coat on the outer surface of adhesive layer 2 oxidation prevention layer 3 is set, oxidation prevention layer 3 mainly is an evoh layer, and its thickness is 0.1-0.15mm, and its significant feature is to stop oxygen to enter pipe interior.
Shown in the above and the figure only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
