What is the road geogrid

What is the road geogrid

Answer:

GeogridThe grid is made of polypropylene, polyvinyl chloride and other high molecular polymer thermoplastic or molded into a two-dimensional grid or a certain degree of three-dimensional grid screen, when used as civil engineering, known as the geogrid
brief introductionGeogrid: GeogridGeogrid is a kind of main geosynthetics, which has unique properties and effects compared with other geosyntheticsGeogrid is often used as reinforcement of reinforced soil structure or composite materialGeogrid is divided into four categories: plastic geogrid, steel plastic geogrid, fiberglass geogrid and polyester warp knitted polyester geogrid
Classified editingPlasticAfter stretching form a square or rectangular net polymer material, according to the manufacture of the tensile direction for different uniaxial tension and biaxial tension. It is two in the polymer sheet by extrusion (the raw material is polypropylene or high-density polyethylene) on the hole, and then the implementation of directional tension in the heating conditions. Tension only along the length direction grid sheet tension; biaxial stretching grille is to continue the grille of one-way drawing again with its length in the direction perpendicular to the tensile material.Because of the polymer plastic geogrid in the manufacture of polymers with heating process and rearrange the directional extension, strengthen the contact force between molecular chains, to improve its strength. The elongation rate of only 10% to 15%. if the original sheet in geogrid with carbon black and ageing resistant material, can make it has good acid and alkali resistance, corrosion resistance and ageing resistance and durability.
