Bai glass fiber geogrid / geogrid

Plastic geogrid is polymer mesh material with a square or rectangular form stretched, stretchable and different two-way stretch stretching direction of its manufacture is unidirectional. It is punched in by squeezing the polymer sheet (mostly raw materials, polypropylene or high density polyethylene), and then the purposes of orientation stretch under heating. Uniaxial tension grid stretching only made along the sheet length direction, and two-way stretch grille is continued to the grid again in uniaxial tension perpendicular to the direction of its length made of stretch. As the plastic in the manufacture of polymer geogrid polymer will be to rearrange the orientation process with the heating extend and strengthen the link between the power of molecular chain, to improve its intensity. Elongation is only 10% to 15% of the original sheet. If the addition of carbon black and other anti-aging material geogrid, you can make good acid and alkali, corrosion resistance and anti-aging durability has.
