What is a one-way plastic geogrid
As the polymer in the manufacture of plastic polymer in the process of heating with the extension of the process of re orientation, strengthen the link between the molecular chain force, to achieve the purpose of improving its strength. Its elongation rate is only 10% ~ ~ of the original plate of 15%. If the carbon black and other anti-aging materials are added in the geogrid, the utility model has the advantages of good acid resistance, alkali resistance, corrosion resistance, aging resistance and the like
The plastic geogrid is a kind of polymer material with square or rectangular shape which is formed by stretching, and it can be used as two kinds of uniaxial tension and biaxial tension. The utility model is punched on the extruded polymer plate (raw material is polypropylene or high-density polyethylene), and then directionally stretched under the heating condition. The unidirectional stretching grid is only drawn along the length direction of the plate, and the bidirectional stretching grid is made by stretching the unidirectional stretching grid in the direction perpendicular to the length.
Uniaxial plastic geogrid is a high strength geosynthetics, with high density polyethylene (HDPE) as raw materials, pressure into a sheet by extrusion and punching network rules, and then the longitudinal stretch into the geogrid, widely used in dam, tunnel, highway, railway, port, construction etc. field
