Bidirectional plastic geogrid

The polymer mesh material with square or rectangular shape formed by stretching plastic can be unidirectional stretching and bidirectional stretching according to the different stretching directions during manufacturing. It is punched on the extruded polymer sheet (the raw materials are mostly polypropylene or high-density polyethylene), and then directional stretching is performed under heating conditions. The unidirectional stretching grid is made by stretching only along the length direction of the sheet; the bidirectional stretching grid is made by continuing to stretch the unidirectional stretching grid in the direction perpendicular to its length.
Bidirectional plastic geogrid
Due to the fact that the polymer polymer of the plastic geogrid will rearrange and orient itself during the heating and stretching process, the bonding force between the molecular chains is strengthened, thereby achieving the purpose of improving its strength. Its elongation is only 10% to 15% of the original sheet. If anti-aging materials such as carbon black are added to the geogrid, it can have better durability such as acid resistance, alkali resistance, corrosion resistance and anti-aging. Mining mining grid is a plastic guard net used in coal mines. It uses polypropylene as the main raw material. After being treated with flame retardant and antistatic technology, it is formed by bidirectional stretching to form a “double-resistant” plastic net with an overall structure. This product is easy to construct, low cost, safe and beautiful
