1.Structure of Geogrid Description:
After stretch forming of polymer with square or rectangular mesh material, according to the drawing direction when different for uniaxial tensile and two-way stretch of two kinds. It is in the extrusion of making polymer plate (raw material for polypropylene and high density polyethylene) on punching, then execute directional stretch under heating conditions. Uniaxial tensile grating sheet along the length direction tensile made only; Two-way is to continue to uniaxial tensile stretch gratings with length of vertical direction tensile again.
Due to the manufacture of plastics geogrids in polymer polymer and rearrange the directional extend along with the heating process, strengthen the binding force between the molecular chain, achieve the goal of improve its strength. Its elongation rate is only 10% ~ 15% of the original sheet. If join in the geogrid anti-aging material such as carbon black, can make its have good acid and alkali resistance, corrosion resistance and anti-aging endurance performance.
2.Main Featrures of Geogrid:
The intnse strength and small deformation.
Corrosion resistance, long service life
Optimum performance and good dimensional stability
