Due to the reorientation of polymers during the heating and stretching process in the production of plastic geogrids, the intermolecular bonding strength is enhanced, thereby increasing its strength. Its elongation rate is only 10% to 15% of the original sheet material.Square or rectangular polymer mesh formed by stretching, which can be uni-directional or bi-directional depending on the stretching direction during manufacturing. It is created by punching holes in polymer sheets (usually made of polypropylene or high-density polypropylene) after extrusion, followed by directional stretching under heat. Uni-directional stretched gratings are made by stretching only along the length of the sheet; bi-directional stretched gratings are produced by further stretching the uni-directional gratings perpendicular to their length.If carbon black and other anti-aging materials are added to geogrids, they can achieve good resistance to acids, alkalis, corrosion, and anti-aging, providing durable performance. Mining geogrids are also known as double-stretched plastic net false ceiling used in underground coal mines, abbreviated as false ceiling net. Mining geogrids are specifically designed and manufactured for false ceiling support and gangway side support during underground coal mining operations. They are made using several high molecular polymer materials and other modified additives, which are then heated, extruded, shaped,Punched, stretched, shaped, and rolled, this product features light weight, high strength, isotropy, antistatic properties, non-corrosive, and flame-retardant characteristics. Compared to mineral geogrids, metal woven mesh, and plastic woven mesh, it is a new type of mesh material for underground coal mine support engineering and civil engineering projects.
