The geogrid mateiral is divided into four categories: plastic geogrid, steel plastic geogrid, glass fiber geogrid and polyester warp knitted polyester geogrid. A grille is made of polypropylene, PVC polymer and thermoplastic or molded by two-dimensional grid or a certain height of the three-dimensional mesh screen, when used as a civil engineering, called geogrid.
Technological advantage of geo-grid fabric
Friction is not easy to produce static electricity. In the coal mine environment, the average surface resistance of the plastic mesh is below 1 * 109 ohms.
Good flame retardancy. It can be up to the standard of MT141-2005 and MT113-1995 in the coal industry.
Easy coal washing. The density of the plastic net is about 0.92, smaller than the density of the water. During the coal washing process, the broken web floats on the surface of the water and is easy to be washed out.
Strong corrosion resistance, anti-aging.
Easy for construction and transportation. The plastic net is relatively soft, and the workers are not to be scratched in the construction, and the utility model has the advantages of easy coiling, bundling, cutting and light weight of the mine grille, and thus convenient for underground transportation, carrying and construction.
Both vertical and horizontal directions have strong bearing capacity. Because the plastic net is biaxially oriented rather than woven mesh, so the creep is small, and the mesh size uniform, can effectively prevent the drop of broken coal, safety and operation safety and protection of underground mine mine workers under the safety of workers
Product features of geogrid mesh material
High strength and little deformation;
Little creep;
Corrosion resistance and long service life: the steel plastic geogrid is made of plastic material, which is protected by various auxiliaries, which has the properties of anti-aging and oxidation resistance, and can be used for corrosion of acid, alkali, salt and other harsh environments. Therefore, the steel plastic geogrid can meet the use requirements of various permanent engineering for more than 100 years, and has excellent performance and good dimensional stability.
The construction is convenient and quick, the cycle is short, the cost is low: the steel plastic geogrid is paved and lapped, the location is easy and smooth, and the overlapping and crossing are avoided, so the engineering cycle can be shortened effectively, and the project cost can be saved.
