Description
Technical field
The present invention relates to PPR pipe technical field, specially a kind of fiberglass reinforced pipe and its production method.
Background technique
PP-R is the abbreviation of polypropylene random copolymer, is also used to refer to the dedicated transport material of cold water pipe and hot water.PP-R
Pipe is called three type PA tubes, atactic copolymerized polypropene, becomes tubing through extrudable using atactic copolymerized polypropene, can also infuse
It is moulded into as pipe fitting.Polypropylene random copolymer is also polyacrylic one kind, and the basic structure of its macromolecular chain is different with being added
The monomer molecule of type is modified, and PPR pipe has section compared with the pipelines such as traditional cast iron pipe, coating steel pipe, pipe of cement
The advantages that material, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construction and maintenance simplicity, long service life can be saved.
But existing PPR pipe have the shortcomings that it is a large amount of, such as existing PPR pipe high temperature resistant and resistance to low temperature compared with
Difference, so that it cannot the use under varying environment again, and existing PPR pipe anti-impact force is weaker, so that long-term use,
It will lead to pipeline and sagging occur, so as to cause the infiltration of oxygen, algal grown inside PPR pipe is caused, to reduce water
Pure, the serious PPR pipe usability and comprehensive of reducing of matter.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of fiberglass reinforced pipe and its production method, existing PPR is solved
Pipe high temperature resistant and resistance to low temperature are poor, so that it cannot the use under varying environment and the weaker problem of anti-impact force again.
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs: a kind of fiberglass reinforced pipe includes inner tube, described
The outer surface of PPR inner tube is fixedly connected with fiberglass layer, and the outer surface of the fiberglass layer is fixedly connected with outer tube.
Further, said inner tube and outer tube are PPR pipe.
Further, the fiberglass layer is made of composite glass fiber enhancing raw material.
A kind of fiberglass reinforced pipe and its production method, comprising the following steps:
Step 1: the material for making PPR pipe to be placed on to the inside of drying machine, PPR pipe material is heated by drying machine,
It is dry；
Material after drying is absorbed by material suction device, then drains into the inside of barrel by second step, passes through grinder-mixer pair
PPR raw material is crushed and is mixed；
Third step, then the PPR raw material mixed and fiberglass reinforced raw material are sent into multi-layer co-extruded machine, and pass through multi-layer co-extruded machine
The die for molding of material push-in moulded products again；
Step 4: molding fiberglass reinforced pipe is cooled down and is formed using spraying box；
Step 5: after cooling and shaping, then by ink jet numbering machine to fiberglass reinforced pipe progress printing character；
6th step draws the fiberglass reinforced pipe after printing character by dragger, then by cutting machine to fiberglass reinforced
Pipe is cut to specific length；
Step 7: carrying out temperature to fiberglass reinforced pipe using the temperature detector between subzero 40 degrees Celsius to 95 degrees Celsius
Degree detection, detects its fiberglass reinforced pipe at a temperature of between subzero 40 degrees Celsius to 95 degrees Celsius, if occurs swollen
Swollen phenomenon recycles pressure checking device to detect the compression strength of fiberglass reinforced pipe；
Step 8: being packed using tubing packaging facilities to the tubing after detection.
Further, the PPR pipe material is dry, and temperature when heating is between 40 degrees Celsius to 60 degrees Celsius,
Drying time is ten minutes to 15 minutes or so.
Further, it is 210 degrees Celsius to 200 that the internal temperature of the multi-layer co-extruded machine, which is set as temperature setting,
Between 20 degrees Celsius.
Further, spray water source is zero degrees celsius to ten degrees Celsius inside the spraying box, and cooling time is eight
Minute was to ten minutes or so.
Further, the pressure detecting machine is 300 pas between 400 pas to fiberglass reinforced pipe detection pressure, is detected
Time is three minutes to five minutes or so.
(3) beneficial effect
The invention has the following advantages:
(1), the fiberglass reinforced pipe and its production method, by the way that on the basis of original PPR water-feeding pipes, composite glass fiber is added in centre
Enhance raw material layer use multi-layer co-extruded Advanced, be combined at high temperature, make fiberglass layer and it is inside and outside PP-R layers it is complete
It is fused together entirely, has fully demonstrated the rigidity and the original all excellent characteristics of PP-R of glass, substantially overcomed PPR pipe
The shortcomings that coefficient of expansion is big under material high temperature, thermal deformation keeps PP-R fiberglass reinforced pipe performance more superior, and it is equally convenient to install, tool
There are higher stability and safety to compensate for limitation of the common PP-R pipe in the application of standpipe, bright tubulature and hot-water line, uses
Range is more extensive, and temperature resistant range is higher, can be used for a long time, have in subzero 40 degrees Celsius to 95 degree Celsius temperature ranges
Brilliant high temperature resistance, under service pressure, the water temperature of pipeline reaches as high as 95 degrees Celsius, resistance to frost
It is good, it is used in freezing state, PP-R pipe resistance to frost is preferable, superpower low-temperature resistance, and subzero 40 degrees Celsius, shock resistance is more
By force, intensity is stronger, prevents pipeline sagging, and the coefficient of expansion is low, solves the problems, such as the oxygen permeability of pipeline, directly contacts with water
Interior table health is nontoxic, good airproof performance, not will form sphagna, and the composition of tubing middle layer completely cuts off outside air completely and do not penetrate into pipe
In road, to inhibit algal grown, keeps water quality fresh pure, meet the use of different location, greatly improve tubing
Usability and comprehensive.
(2), the fiberglass reinforced pipe and its production method mainly can be by former materials by the heating and drying to raw material
The moisture and water source of material are dried, in order to improve the effect after pipeline production, and can be very by grinder-mixer
Good is crushed and is mixed to PPR raw material, and the quality of production is improved, and can be very good to increase glass by pressure detecting machine
Whether strong pipe carries out pressure detecting,, can be quickly right by these equipment in order to quickly examine fiberglass reinforced pipe qualified
Fiberglass reinforced pipe is produced, time saving and energy saving, and reduces cost of labor, meets the use of different factories.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
