Non Woven Geotextile Resistant To Aging, Corrosion Resistance

- Aug 29, 2017 -

The emergence of non-woven geotextile weaving geotextile late, its production methods are mainly spunbond method and acupuncture method. Which acupuncture in China accounted for a larger proportion. The raw materials used mainly polyester, followed by polypropylene and vinylon, the unit weight of 100 to 800 grams / square meter. Non-woven geotextiles have a large elongation, can adapt to the larger deformation, according to the need to make the appropriate size of the pores, and in the horizontal and vertical direction have a better penetration. Therefore, the development of non-woven geotextile fast, and has become a major component of geotextile. (Bentonite waterproof blanket HDPE impermeable membrane)

Non-woven geotextiles are now widely used to solve the problem of subgrade subsidence and frosting mud, drainage systems for earth and rock dams, underground drainage pipes, soft foundation reinforcement, various embankment slope protection and other engineering filter layer. In addition, it can also be used for soil reinforcement materials, so that the soft foundation reinforcement or the construction of light retaining wall, at the same time, but also reduce the embankment under the pore water pressure.

Dezhou Huaxiang new materials are specialized in producing all kinds: filament geotextile, short wire geotextile, hdpe geomembrane, composite geomembrane, eva waterproof board, rough geomembrane, geogrid, impermeable membrane, exhibition carpet, Steel, machinery, water conservancy, electric power, soil and water conservation and environmental greening and infrastructure construction. It is widely used in aviation, aerospace, military, chemical, petroleum Field, get the customer's praise.

Non-woven geotextile concept:

Non-woven geotextile (polyester geotextile, non-woven geotextile), also known as geotextile, it is made of synthetic fiber through acupuncture or weaving through the permeability of geosynthetics. Finished cloth for the cloth, the general width of 4-6 meters, the length of 50-100 meters. Geotextile is divided into a woven geotextile and non-woven geotextile. Geotextile has excellent filtration, isolation, reinforcement protection, high tensile strength, good permeability, high temperature, anti-freeze, anti-aging, corrosion resistance.

The separation of geotextiles is to prevent the mixing of adjacent heterogeneous soils or fillers. It is mainly used for the separation of structural materials of different layers of roads and dikes.It avoids the mutual doping of different materials and affects the quality of the project, and makes the construction convenient and the project progresses. At this point, asked the geotextile porosity is small, the best use of non-woven geotextile.

The anti-seepage effect of the geotextile is mainly used for the dam, irrigation channel and the pool of the water side and the inside of the waste piling pool to prevent the infiltration of water and toxic waste. Where the geotextiles are generally coated with geotextile or polymer made of geomembrane. Impermeable geotextiles are usually made of cloth asphalt or glued rubber. Geomembrane mainly polyethylene. Polypropylene and polystyrene. Polyethylene is less stable and easy to aging, while the soft texture of polyethylene is not easy to aging. Generally use high-density polyethylene and soft gather together (the plasticizer containing the resin containing the prison 30% -70%) as a geomembrane.
