Huzhou Glass Fiber Geogrid Specifications and Pricing, Plastic Geogrid, Road Base Geogrid, Steel-Plastic Geogrid
Polymers meshes, formed by stretching into square or rectangular shapes, can be either unidirectional or bidirectional stretched depending on the stretching direction during manufacturing. They are produced by punching holes into polymer sheets (usually made of polyethylene or high-density polyethylene) after extrusion.
Then, directional stretching is carried out under heating conditions. Single-directional stretched mesh is made by stretching only along the length of the sheet; bidirectional stretched mesh is produced by further stretching the single-directional mesh perpendicular to its length. As the polymer高分子 in the plastic geogrid reorients during the heating and extension process, the intermolecular bond strength is enhanced, thereby increasing its strength. Its elongation rate is only 10% to 15% of the original sheet. If carbon black or other anti-aging materials are added to the geogrid,
It offers excellent resistance to acids, alkalis, corrosion, and aging. Mine-used geogrid, also known as the double-stretched plastic mesh false ceiling used in underground coal mines, is abbreviated as false ceiling mesh. The mine-used geogrid is specifically designed and manufactured for false ceiling support and gangway side support during underground coal mining operations.
It is manufactured through a series of processes including heating, extrusion, shaping, punching, stretching, forming, and rolling, utilizing several types of high molecular polymer resins and other modifiers. Compared to metal woven mesh and plastic woven mesh used in mining, the geogrid for mining has the characteristics of light weight, high strength, isotropy, antistatic properties, corrosion resistance, and flame retardancy. It is a new type of mesh material for support engineering in coal mines and civil engineering projects.
