Product Introduction

Flame retardant and anti-static biaxial geogrid

 

 

Double resistant plastic mesh.The grids have an integrally formed structure with high tensile strength on MD and TD directions.
MTTVS Mining Grids are manufactured from special formula with flame-retardant polymer.
The geogrid used in coal mines is a "dual resistance" plastic mesh independently developed by our company.
The geogrid used in the mine is a square grid with polypropylene as the main raw material, which has been treated with flame retardant and anti-static technology and formed by biaxial stretching method.

1. Mining grilles are less prone to generating static electricity due to friction. In the underground environment of coal mines, the average surface resistance of plastic mesh is 1 × Below 109 Ω.

2. The mining geogrid has good flame retardant performance. In an open flame environment, it only melts and does not burn, even if it burns for no more than 10 seconds before extinguishing.

3. Easy to wash coal. The density of this plastic mesh is around 0.92, which is lower than the density of water. During the coal washing process, the broken mesh floats on the water surface and is easy to rinse off.

4. Mining grid has strong corrosion resistance and aging resistance.

5. Easy for construction and transportation. Plastic mesh is relatively soft and should not scratch workers during construction. It also has the advantages of easy curling and bundling, light cutting and specific gravity of mining geogrids, making it easy to transport, carry, and construct underground.

6. Strong load-bearing capacity in both vertical and horizontal directions. After being processed by extrusion and stretching processes, the molecular structure of the plastic mesh is reoriented, and the tensile strength of the material is 2-3 times higher than before stretching. The reinforcement and ribs formed by bidirectional stretching are perpendicular to each other, and this structure allows the pressure applied to the mesh surface to be effectively transmitted to the surrounding reinforcement ribs through the nodes, greatly improving the overall pressure bearing capacity of the mesh surface. When an external force is applied to a particular tendon (or rib), it also evenly distributes the external force to other tendons (or ribs), reducing the concentrated load-bearing capacity of a single tendon, making it less likely to cause the rib to fracture. Secondly, due to the fact that this type of plastic mesh is biaxially stretched rather than woven, the creep deformation of the mesh is small, and the mesh size is uniform, which can effectively prevent the falling of coal fragments, protect the safety of underground workers and the safety of underground workers and the operation of mining cars.
