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
