Geotextile
The introduction and applications of the Geotextile:
Geotextile uses the polypropylene and polyester staple fiber as the main raw material. It is made by opening, carding and mixed and disorderly, webbing, acupuncturing and other crafts. The product has the following features: excellent permeability, filterability, and durability characteristics, such as: tensile strength, tear strength, bursting strength and high mechanical properties. It can be widely used in railways, roads, sports venues, dams, water and soil building, tunnel, tidal flats, reclamation, environmental protection and other projects. And can play a unique effect in the engineering.
The characteristics of the geotextile:
1, The mesh is not easy to be to jammed. Because it did not finalize the network of fibrous tissue structure should be modified and motility.
2, High water permeability, under the pressure of earth moving, can still maintain good water permeability.
3, Corrosion resistant, uses the polypropylene and polyester chemical fiber as raw materials, etc. Alkali resistance, no corrosion, no bug eat by moth, resistance to oxidation.
4, Easy construction, light weight, easy to be used.
The applications of the geotextile:
Geotextiles can be widely used in water conservancy, water and electricity, roads, railways, ports, airports, sports venues, tunnel, tidal flats, reclamation, environmental protection and other fields, has the function of isolation, filtration, drainage, reinforcement, protection, sealing, etc.
