Synthetic Material Geogrid
Synthetic Material Geogrid is a kind of important special geosynthetics, American Society of testing and materials ASTM defined it as: Synthetic Material Geogrid is a planar open network structure of global coherence, the larger pores in the matrix, reinforced soil, in the use of stones or other building materials can penetrate in the grid. Project mainly enhanced the protective effect. Most of the raw materials of the geogrid are polyethylene, polypropylene or high strength polyester. Most of the post-processing of Synthetic Material Geogrid uses the coating process of polymer (such as asphalt, rubber, PVC, etc.). In recent years, the selection of raw materials for Synthetic Material Geogrid has also tended to diversify, and high performance fiber, such as glass fiber and composite fiber, has been applied. According to the production mode of geogrid, the Synthetic Material Geogrid can be roughly divided into the following categories:
A. Extrusion molding geogrid-firstly punch holes on polymer sheets made by extrusion, then unidirectional or bidirectional directional stretching the holes larger to form geogrid, raw material is polyethylene and polypropylene. Most of the original geogrid use this method of production.
B.The woven method geogrid is the most widely used, with the largest yield and the relatively wide variety. It is mainly made of high strength weaving polyester or fiberglass yarn and coated with PVC or asphalt to form geogrid. At present, the products of several major synthetic material geogrid production companies in the world are all such kind.
C.The geogrid of the knitted geogrid is a new product in the field.
