Extruded Plastic Polypropylene Geogrid
Extruded plastic polypropylene geogrid is one of the biaxial geogrids. It is formed by stretching the polymer mesh. According to the different direction of tension, it can be divided into two types: uniaxial tension and biaxial stretching, namely, one way geogrid and two way geogrid.
Extruded plastic polypropylene geogrid is ribbed belt by polymer plastic extrusion stretch forming, high tensile strength, the transfer point of its longitudinal and transverse rib belts with high frequency ultrasonic welding, ensure the stability of the product quality, to ensure the effective soil of interlocking grid. At the same time, the strength of the grille can change the pulling force of the ribs, adjust the number of ribs, and design different models and specifications to meet the needs of different engineering and various technical indicators.
Due to the rearrangement of polymers in the manufacture of plastic geogrids, polymers will rearrange their orientation along with the heating and extending process, and enhance the bonding force between molecular chains, so as to improve their strength. Its elongation is only 10% ~ 15% of the original plate. If the anti aging material such as carbon black is added to the geogrid, it can have good durability, such as acid resistance, alkali resistance, corrosion resistance and aging resistance.
The main function of extruded plastic polypropylene geogrid: avoid landslides, rock loose and soil erosion, can be made of stone cage; shore engineering and hydrographic engineering, with strong flexibility, good permeability, not eroded by water, and can absorb shock wave; can be made into a rectangular, square or tubular directly installed in the stone cage under water, without the need for expensive diving.
