        Shanxi Changzhi Yue manager 15550827699 non-woven geotextiles manufacturers, anti-seepage geomembrane cheap factory direct supply of long-term supply of low-cost coal mine underground reinforced plastic net false roof welding PET polyester geogrid, plastic geogrid, steel plastic geogrid, fiberglass geogrid, geotextile composite geomembrane, 3D Geomat, soft permeable pipe, plastic blind ditch drainage pipe geotextile material for polyester fiber.
geotextile also called geotextile, which is permeable geosynthetic materials by synthetic fibers or woven by acupuncture. The finished product is a cloth shaped, the general width of 4-6 meters, length 50-100 meters. Geotextiles are divided into nonwoven geotextiles and geotextile. With excellent filtering, isolation, reinforced protection function, high tensile strength, good permeability, high temperature resistance, anti freezing, aging resistance, corrosion resistance of geotextiles.
geotextile is mainly used in the following projects:
(1) highway (including temporary road) railway, bank, embankment dams, airports, sports grounds and other projects, in order to strengthen the weak foundation, at the same time isolation and filtering effect. River, river, lake, sea slope of the geotextile, also can prevent water blunt turbidity.
(2) for retaining wall backfill reinforcement, or for anchored retaining wall panel. The construction of package type retaining wall or abutment.
(3) reinforced flexible pavements, crack repair on the road, to prevent reflection crack of bituminous pavement.
(4) to increase the stability of crushed stone slope and reinforced soil, prevent freezing soil erosion and the low temperature.
(5) the isolation layer between the road ballast and subgrade, isolation layer or between the embankment and soft foundation.
(6) artificial fill, rockfill materials or field isolation layer and the foundation, isolation between different frozen soil. Anti filter and reinforcement.
(7) of ash storage dam or tailings dam upstream dam surface at the early stage of filter layer, filtering layer retaining wall back fill in drainage system.
(8) or gravel filter layer surrounding the drain pipe drainage of the surrounding.
(9) in water conservancy project wells, relief wells or inclined pipe filter layer.
(10) isolation layer soil between highway, airport, railway ballast and artificial rockfill and soil fabric.
(11) in ternal vertical or horizontal drainage, the dissipation of pore water pressure in soil buried.
(12) and drainage of Geomembrane in earth dam or embankment behind or concrete cover the lower part of the.
(13) exclude tunnel surrounding water seepage, reduce the lining is exposed to external water pressure and the seepage around buildings.
(14) artificial filling foundation motion field foundation drainage. The raw
geotextile

1. geotextile materials used not only to the physical and chemical properties are required for its use in environment into consideration, but also pay attention to the product cost. In terms of performance mainly consider the following aspects:
1.1 good physical and mechanical properties of
geotextile working environment is bad, a lot of cases is soaked in water or shop on the humidity big soil, so must have good hydrolysis resistance and wet mechanical properties.
1.2 ultraviolet radiation resistance, hydrolysis resistance, high and low temperature resistance
geotextile to exposure to the sun, so shall have the corresponding anti UV properties; geotextile to adapt and asphalt materials such as contact temperature requirements, high melting point.
1.3 chemical resistance, corrosion resistance, anti - mildew
water and soil is the same, some alkaline, some acidic salt, some more, some with a variety of elements, so it must be with the chemical stability.
1.4 good water permeability
geotextile filtration and drainage needs permeable, so it must be with good water permeability.
currently geotextile materials mostly used polymer, which is the most used polypropylene raw materials (including fiber), which accounts for more than the total amount of geotextile, 50%, the United States has accounted for more than 80%. Polyester raw material (including polyester) accounted for 15%-30%, in second place, the Japanese used more. Using polyethylene and polyamide fiber less, our country still has adopted the vinylon.
polypropylene material used up, the price is certainly an important factor, but mainly polypropylene has excellent acid and alkali resistance, corrosion resistance, mildew, not eroded by bacteria; and there is a good wicking effect, permeability to water well. The mechanical performance is also very good, especially in recent years, China has developed a high strength polypropylene filament strength reached 8g/D, production of high strength polypropylene woven geotextiles and cloth are suitable for.
polypropylene fiber deficiency is anti ultraviolet performance is poor, especially for the UVB wave band ultraviolet sensitive, experiments show that in spring and summer, across the glass in the light of 6 months, its strength is reduced to 0, but still could maintain 78% polyester, nylon 73%, polypropylene due to this must be approved by the anti aging treatment in spinning the former, in the use and transportation must try to avoid exposure in the sun. In addition, the polypropylene fiber with low melting point (at about 135 DEG C), so in and asphalt sealing materials and paving materials combine limited. Mechanical and physical properties of
polyester, high melting point than polypropylene fiber, ultraviolet radiation resistance than polypropylene is much better, so is the ideal material for geotextiles. Polyester good acid resistance, alkali resistant also, but the long-term contact with alkaline materials such as lime, cement, concrete, alkali soil, strength will suffer, the hydrolysis resistance is poor, should be careful when using.
nylon and vinylon alkali resistance is good, but the acid difference. Polyamide filament at pH 4, 25 C in buffer solution after 11 months, the strength only to 1%, polyamide geotextile should not be used for pH< 5 in the soil, otherwise not durable. Vinylon seawater corrosion resistance, suitable for coastal engineering.
