Background technique
Since with silica sand as centre strengthen main body chamber for fibre-reinforced plastics sand inclusion pipe invention since, more and more many foundation engineerings start this kind of pipeline of extensive use, a large amount of silica sand application and exploitation are also with simultaneously and are served problem, such as exploit the problem to environment and soil erosion weathering, the problem of silica sand Appropriate application, exploitation and the problem etc. of application cost, the almost identical Desert Sand of performance of comparing composition does not then have above problem;
Desert, the whole world gross area more than 4,800 ten thousand sq-km, account for 1/3rd of land, according to statistics, Deserts in China, Gobi desert and desertification land area amount to about 130.8 ten thousand square kilometres, account for 13.5% of area, in desert zone based on the desert on mobility sand dune, account for national desert area more than 70%, in the face of the massive losses that " desertification " is brought to the mankind, the mankind must preserve our planet environment, to plant trees energetically, afforestation desert, this has been the common recognition that the whole world is reached, simultaneously, utilize Desert Resources, turn waste into wealth, loop transformation desert Environment is also one of method recognized in the world, the composition that Desert Sand is the most general be silica (
siO), be generally the form of quartz, because of its stable chemical nature and quality hard, and resist weathering, at present, very ripe as the pipeline of middle reinforcement layer main body with silica sand, be widely used accreditation, plays a significant role in infrastructure, the main constituent of Desert Sand and silica sand be all silica (
siO), its content of general Desert Sand is all more than more than 90%, add Desert Sand baptism through nature in forming process, uniform particles, dry firm, be excellent natural reinforcing filler, also very good with the combination of unsaturated resin, the more important thing is that these natural raw materials are drawn materials conveniently, not only need not physical environment be destroyed, can also be recycling as and improve desert Environment and provide convenient,
Bentonite clay (English bentonite by name) is the moisture clay pit based on smectite.The chemical composition of smectite is: (Al2, Mg3) Si
4o
10oH
2nH
2o, because it has special character, as bloating tendency, cohesiveencess, adsorptivity, catalytic, thixotropy, suspension and cation exchange, organobentonite is a kind of inorganic mineral/organic ammonium composite, take bentonite clay as raw material, utilize the lamellar structure of smectite in bentonite clay and swellingly in water or organic solvent can be dispersed into colloid clay characteristic, insert organic covering agent by Ion exchange technique to make, organobentonite is at all kinds of organic solvent, oils, gel can be formed in liquid resin, there is good thickening property, thixotropy, suspension stability, high-temperature stability, lubricity, film forming, water resistence and chemical stability.Be exactly utilize above-mentioned advantage in the present invention, incorporate according to a certain ratio in pipeline manufacture process, make pipeline pipe interior on the basis that rigidity satisfies the demands finer and close, waterproof, resistance to compression, toughness is outstanding.
Summary of the invention
The invention provides with the unsaturated resin of the main material-Desert Sand of a kind of novel enhanced and special formulation mixing cured as middle reinforcement layer; the nonmetal plumbing multiple tube that pipeline internal and external layer is formed prepared by employing alkali-free glass fibre reinforced plastic; there is resistance to compression, antidetonation, corrosion-resistant, high temperature resistant, good insulating, excellent in mechanical performance, the good characteristics such as easy for installation; being applied in water supply and sewerage pipeline making as the main material of enhancing by Desert Sand first, is a kind of resource circulation utilization and the unique novel product improving desert Environment; The present invention is achieved through the following technical solutions: a kind of Desert Sand is as the nonmetal plumbing multiple tube of middle reinforcement layer main body; it is characterized in that: middle reinforcement layer is Desert Sand and forms through the unsaturated resin of special formulation is mixing cured, and interior laying adopts glass fiber reinforced plastic water proof to form; The glass fiber reinforced plastic that outer laying winding process or spun casting technique are made, inside/outside bed layer thickness is respectively (1.2 ~ 5.0) mm, and pipeline nominal diameter can be (100 ~ 4000) mm; Composite filling definite-length-winding process, spun casting technique, continuous winding technique can be adopted to make according to equipment situation; Feature of the present invention and effect are: have employed a kind of novel pipeline mesosphere reinforcing filler-Desert Sand (maximum particle diameter is at below 2.5mm) first; mixing cured shaping with the unsaturated resin of special formulation; make the advantages such as such nonmetal plumbing multiple tube possesses resistance to compression, corrosion-resistant, long service life, cost are low, easy transportation and installation; to the application development of pipeline and environmental protection, waste utilization, improving desert Environment afforestation etc. has significantly society and economic value.In addition, desert of drawing materials, again by the pipe applications of this invention in improving desert and greening, be kind here greatest in fact.
Accompanying drawing explanation
Accompanying drawing 1 is the front cross-sectional schematic diagram of the nonmetal plumbing multiple tube of the present invention
(1) alkali-free glass fibre reinforced plastic is outer, the unsaturated resin solidification enhancement layer of (2) Desert Sand mixing special formulation, (3) alkali-free glass fibre reinforced plastic water proof internal layer, (4) water proof liner.
