Highway And Railway Soil Stabilization 2020 PP High Strength Biaxial Plastic Geogrid
Biaxial Plastic Geogrid Introduction
Plastic geogrid is a kind of polymer mesh material with square or rectangular shape formed by stretching. It can be divided into uniaxial tension and biaxial tension according to the different stretching direction. It is to punch holes on the extruded polymer sheet (mostly polypropylene or high density polyethylene) and then perform directional drawing under heating condition.
The unidirectional tension grid is only made along the length direction of the plate, while the bidirectional tension grid is made by drawing the unidirectional tension grid in the direction perpendicular to its length. In the manufacturing process of the plastic geogrid, the polymer will be reoriented with the heating extension process, which strengthens the bonding force between the molecular chains and achieves the purpose of improving its strength. Its elongation is only 10% ～ 15% of the original sheet.
If carbon black and other anti-aging materials are added to geogrids, they will have better durability such as acid, alkali resistance, corrosion resistance and aging resistance. Bi directional geogrid bi directional geogrid is made of high molecular polymer through extrusion, plate forming, punching process and then longitudinal and transverse tensile. The material has a great tensile strength in both longitudinal and transverse directions, which is a kind of structure

Biaxial Plastic Geogrid Application
(1) It has no deformation and good creep resistance under long time continuous load.
(2 Large friction coefficient (mostly around 0.8) and strong force of stone, sediment and concrete are conducive to prevent slippage.
(3) It is stable in chemical properties, resistant to acid, alkali, salt solution, or gasoline, diesel and other organic solvents, can not be decomposed by water, resistant to environmental stress fragmentation and microbial damage.
(4) light weight, easy to transport, simple and convenient construction, low maintenance cost; aging resistance, bearing load, service life of more than 120 years
