Description:

The mine plastic mesh is a square grid with a whole structure formed by polypropylene as the main raw material, after being treated with flame-retardant and anti-static technology, and formed by biaxial stretching.

Application: Mine plastic mesh is mainly used as false roof and protection for slicing mining of thick coal seams in underground coal mines. It can also be used as a supporting material for various roadways such as bolted roadways, supporting roadways, and bolted shotcreting roadways. It can also be used as other materials. Anchoring and reinforcing materials for mine roadway engineering, slope protection engineering, underground civil engineering and traffic road engineering are good substitutes for plastic textile mesh and steel wire mesh.

Feactures:

1.     The elongation rate of the product is small, and the measured data is 4.1%, which effectively avoids the phenomenon of "net bag" in practical applications.

2.     The appearance of the product is a corrosion-resistant modified plastic, which will never rust and fail due to corrosion, ensuring a permanent protective effect.

3.     The product weighs about 0.9-1.3 kg per square meter, which is only about 1/3 of the metal protective net of the same specification. The size can be freely cut, which is convenient for application unit purchasing, management and storage, and also convenient for operation site management. The product has good flexibility, reduces the labor intensity of workers, and can effectively improve work efficiency.

4.     The breaking force of a single mesh belt of 8 steel wires is ≥4000N, and the strength reaches or exceeds the same type of metal mesh.

5.     Double anti-static performance (antistatic performance, flame retardant performance) advanced technical indicators, improve the safety of underground applications.

6.     The price is lower than the same type of metal mesh, which can effectively reduce the cost of mine support.

7.     The modified outer covering plastic layer has a stronger affinity with concrete, can improve the strength of shotcrete roadway support, has strong shear resistance, effectively overcomes the limitations of all-plastic mesh in practical applications, and has a wide range of applications.
