Abstract
Inorganic compound material pressure pipe and moulding process adopt the composite material of wear-corrosion resistance polyester resin and glass fibre earlier or form the inside lining anti-corrosive wearing layer with pvc pipe.Twine high performance inorganic complex material again, and through curing, the demoulding, solidify to form in the middle of the force structure layer.Inorganic composite materials is that glass fibre is obtained behind the impregnation in by the glue of preparations such as magnesium oxide, magnesium chloride solution.Apply polyester resin at last, the composite material of glass fibre forms external protection.This pressure tube proportion 1.8-2.0.Easy transportation and installation, corrosion resistance, refractory nature is good, and rigidity is big, distortion is little, can bear the barometric pressure in the 10kg.
Description
The present invention relates to the pressure piping field, relate to the pressure piping technology of making particularly of inorganic composite materials.
At present, the domestic and international pressure piping that adopts has many kinds, as reinforced concrete prestressed pipe, steel pipe, cast iron tube, plexiglass steel pipe etc.All there is deficiency separately in these pressure pipings, and are very thick as the tube wall of reinforced concrete prestressed pipe, weight is big, installation and transportation are difficult, corrosion-resistant, specific strength are low.Steel pipe, cast iron tube corrosion-resistant, easily get rusty, weight is big, installation and transportation are difficult, moulding is inconvenient.The plexiglass steel pipe is thermo-labile, serviceability temperature is low, price is expensive.
Had in the market with magnesium chloride, magnesium oxide, glass fibre be that the inorganic composite materials ubiquity intensity of main raw material is low, problem such as poor water resistance, counter tide phenomenon are serious, the not high products of every performance requirement such as corrugated tile can only be produced, pressure piping can not be used for making at all.Hand pasting forming is all adopted in the moulding of inorganic composite materials product at present in addition, and not only manufacturing efficiency is low, and poor performance, the quality instability.
The objective of the invention is low at present inorganic composite materials product forming technique level, as can not to be used to produce pressure piping present situation, be intended to design a kind of pressure piping and moulding process of producing with inorganic composite materials thereof, this pipeline low price, in light weight, intensity is high, good corrosion resistance.
The objective of the invention is to realize in the following manner; inorganic compound material pressure pipe is the pipeline that is made of inside lining anti-corrosive wearing layer (1), middle force structure layer (2) and external protection (3); caliber 100-2000mm, inside lining anti-corrosive wearing layer adopt the pipe or the hard PVC pipe of 90% corrosion-resistant polyester resin and 10% glass fibre straight forming.
Middle force structure layer adopts high performance inorganic complex material to be entwined.Inorganic composite materials is that glass fibre impregnation, moulding, the curing in the glue of 70-90% with 10-30% forms, and glue is formulated by magnesium oxide, magnesium chloride solution, ferrous sulfate, calcium sulfate, pulverized fuel ash, French chalk, early strong powder.
External protection adopts the organic composite material coated by the antiager UV-9 preparation of 86-90% polyester resin, 9% glass fibre, 1-5% to form.
The moulding process of inorganic compound material pressure pipe:
(1) composite material straight forming or the employing hard PVC pipe that adopts 90% corrosion-resistant polyester resin and 10% glass fibre to form forms the inside lining anti-corrosive wearing layer.
(2) earlier with 58.3-34.7% magnesium oxide, 26.3-31% magnesium chloride solution (D1.1-1.3), 1.2-3.5% ferrous sulfate, 1.2-1.7% calcium sulfate, 5.9-17.3% pulverized fuel ash, 5.9-10.4% French chalk, the early strong powder of 1.2-1.4%, be made into glue, then get glass fibre after cationic activation is handled, place glue, impregnation under the 1kg barometric pressure, form high-effect inorganic composite materials, winding on internal lining pipe again, curing, the demoulding, again solidify to form in the middle of the force structure layer, the proportioning of glass fibre and glue is 10-30%: 70-90%.
(3) will on middle force structure layer, form external protection by the polyester resin of 86-90%, 9% glass fibre, the organic composite material coated that 1-5% antiager UV-9 is mixed with.
Accompanying drawing is this pressure tube structure cut-away view.
The inside and outside layer thickness of inorganic compound material pressure pipe is respectively 0.5-4.0mm, 0.3-1.5mm.The thickness of middle force structure layer is determined after according to the required calculation of pressure of bearing of pipeline.
The force structure layer adopts " high performance inorganic complex material " of application simultaneously in the middle of this pressure tube, this mechanical properties of materials height, and its stretching, flexural strength can reach 100MPa, and water resistance is good, and its coefficient of softing is more than 0.8.The pressure pipe that adopts this material to make middle force structure layer can stand＜the atmospheric pressure of 10kg.
This pressure tube proportion has only 1.8-2.0, and low than concrete reinforced pipe, cast iron tube, steel pipe, this from following table as seen
| Kind | Specific strength | 600mm is with pressure tube heavy (kg/m) |
| The reinforced concrete prestressed pipe | 200 | 470 |
| Cast iron tube | 250 | 232 |
| Steel pipe | 500 | 131 |
| Inorganic composite materials | 700 | 45 |
This pressure tube specific strength is higher than three kinds of pipes as seen from the table, and weight is but light than it, and good corrosion resistance, long service life, that the construction transportation is installed is all convenient.This pressure tube cost is lower than cast iron tube, steel pipe in addition, the height of the flow-rate ratio steel pipe of unit section pipe.
This force pipe relatively has following advantages with the lucite steel pipe:
1, good heat resistance can use below 400 ℃, and heat-resisting polyester glass tube serviceability temperature generally is not higher than 100 ℃;
2, fire line is good, belongs to not fire product;
3, rigidity is big, distortion is littler, elastic modelling quantity is high;
4, low price, cost hangs down 1/3-1/2.
