Abstract
The invention discloses the PPR pipe that a kind of high temperature resistant is difficult deformation, by adding high temperature resistance layer in the middle of PPR pipe part inner and outer wall so that PPR pipe will not be bent in high temperature, play humidification, remove the potential safety hazard in construction, use.
Description
Technical field
The PPR pipe of deformation is difficult the present invention relates to PPR pipe field, more particularly to a kind of high temperature resistant.
Background technology
PPR is the abbreviation of 3 third polyethylene, is called polypropylene random copolymer pipe, by the way of thermal welding, there is special
Welding and cutting tool, there is higher plasticity.Price also very economical.Additional heat-insulation layer, heat-insulating property more preferably, tube wall also very light
It is sliding, do not include the joint of inside and outside silk.Embedded wall is generally used for, or in deep-well built-in pipe.Pipe-line system is safe and reliable, not
Infiltration, service life was up to 50 years.But construction technical requirement is high, it need to be constructed using specific purpose tool and professional person, can
Ensure system safety.
Inherently a kind of High molecular polymer of PPR materials, and it is current with the tubing of PPR material manufactures to be entirely capable of pressure-bearing
The tap water pressure of national standard.The cost of PPR materials is also more much lower than stainless steel material, and the technique of manufacture uses mould skill
Art, is more suitable for producing in enormous quantities.
However, according to statistics, if it is for domestic hot-water, PPR pipe is resistant to temperature for 70 degree for a long time.Short time can be with resistance to
By 90 degree of temperature.
Heating is if it is for, PPR pipe highest operating temperature is 80 degree.The maximum temperature that short time can be resistant to is
90 degree.
As can be seen here, existing PPR pipe part only has a body, in actual use such as high temperature, can soften, make engineering
In there is potential safety hazard, be also not suitable for high-temperature operation.
The content of the invention
In view of this, the invention provides the PPR pipe that a kind of high temperature resistant is difficult deformation, by PPR pipe part inwall and outside
High temperature resistance layer is added in the middle of wall so that PPR pipe will not be bent in high temperature, play humidification, removed in construction, use
Potential safety hazard.
The technical solution adopted in the present invention is：A kind of high temperature resistant is difficult the PPR pipe of deformation, the PPR pipe include outer wall,
One layer of high temperature resistance layer is added in the middle of inwall and hollow structure, the outer wall and inwall.
Further, the high temperature resistance layer is glass fibre.
Further, high-temperature-resistant layer is scribbled on the inwall.
Further, the high-temperature-resistant layer thickness is 1-5 millimeters.
The outer wall and high temperature resistance layer central filler are combined PPR, the outer wall and high temperature resistance layer by PUR it is Nian Jie and
Into；The inwall is combined PPR with high temperature resistance layer central filler, and the inwall is formed with high temperature resistance layer by the way that PUR is Nian Jie.
The beneficial effects of the invention are as follows：The present invention by added in the middle of PPR pipe part inner and outer wall high temperature resistance layer so that
PPR pipe will not be bent in high temperature, play humidification, remove the potential safety hazard in construction, use.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the invention.
Wherein, 1, outer wall；2nd, inwall；3rd, high temperature resistance layer；4th, hollow structure.
Embodiment
Below with reference to accompanying drawing, the present invention is described in detail, as shown in figure 1, a kind of high temperature resistant that the present invention is provided is not
The PPR pipe of easy deformation, the PPR pipe includes adding one layer in the middle of outer wall 1, inwall 2 and hollow structure 3, the outer wall and inwall
High temperature resistance layer 4.
As the another improvement of technical scheme, the high temperature resistance layer 4 is glass fibre.
The PPR pipe part for having added high temperature resistance layer possesses following major features:
1st, linear expansion coefficient is only 20~30% or so of common PPR products；Thoroughly solve the flexible of plastic conduit
Problem.
2nd, tubing rigidity reinforced, prevents pipeline sagging, while the density and quantity of the fixed strong point are also reduced, from
And reduce the comprehensive cost of engineering.
3rd, stress levels are higher, and in the case where being commonly designed power of trembling, service life is longer.
4th, more preferably, energy-saving consumption-reducing effect is obvious for resistance to elevated temperatures；FR/PPR is applied in hot-water heating system, normal temperature in use
Up to 95~100 DEG C, the temperature using medium is both improved, the thickness of insulation material can be reduced again, its integrated cost is lower.
5th, water-carrying capacity is big:Under the other pressure condition of ad eundem, the wall thickness book of FR/PPR tubing adds the interior of tubing
Footpath, so as to improve water-carrying capacity (increase by 20%).
6th, the oxygen flow sex chromosome mosaicism of pipeline is solved, the interior table health directly contacted with water is nontoxic, good airproof performance, will not be formed
Sphagna.The composition in fiberglass reinforced FR/PP-R tubing intermediate layer, completely isolation extraneous air is not penetrated into pipeline, so as to suppress algae
Class grows, and keeps water quality fresh pure
As the another improvement of technical scheme, high-temperature-resistant layer is scribbled on the inwall 2.
As the another improvement of technical scheme, the high-temperature-resistant layer thickness is 1-5 millimeters.
Specifically, high-temperaure coating therein is a kind of slurry of bone white, with energy-efficient, thin layer thermal insulation,
Fire retardant anticorrosion, electrically isolate from integral new type reflection heat insulating coatings, coating can be connected in body surface formation by closing microballon
Three-dimensional network hollow-core construction together, effectively prevents heat from conducting and heat exchange.
In addition, the thickness of the high-temperaure coating is between 1mm-5mm, it is uniform to apply the internal layer for being bonded at whole PPR inwalls；Institute
There are the PPR surfaces with inner bag high temperature hot water contacts to apply the high-temperaure coating of viscous respective thickness.The thickness of heat-insulation layer according to
Required heat-insulating property is configured.
As the another improvement of technical scheme, the outer wall is combined PPR with high temperature resistance layer central filler, described
Outer wall is formed with high temperature resistance layer by the way that PUR is Nian Jie；The inwall and high temperature resistance layer central filler are combined PPR, the inwall with
High temperature resistance layer is formed by PUR bonding.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
Protection scope of the present invention.
