1. Long polyester fiber, PVC coating 2. Light, fire retarding, static conduction 3. Coal mine protection,underground project
Introduction
Coal mine reinforced polyester fiber fake ceiling protective mesh
1. Adopting high-modulus and high strength long polyester fiber as its body.
2. Warp knitting and bundling by advanced German imported machine.
3. Coating with fire retarding and static conducting material.
4. A good substitute for metal mesh, plastic mesh, steel-plastic composite mesh, packing belt mesh and etc.
Characteristics
1. Soft, light, high tensile and high strength of the junction.
2. Acid and alkali resistance, cold and moisture resistance.
3. Corrosion resistance, long life, fire retarding and static conduction.
Application
1. Fake ceiling supporting in stoping face.
2. Anchoring and shotcreting tunnel supporting.
3. Temporary and permanent supporting in tunnel.
4. Other mining tunnel projects and underground civil engineering.
Benefits
1. Avoiding tunnel sliding, leakage of gangue and roof falling and improving mine safety
and reducing mining accidents.
2. Reducing ventilation resistance and saving energy.
3. Recyclable and easy installing.
