Hebei Maosen mine reinforcement material Guris factory direct sales

Description
Grass is a polyurethane product composed of two components, used for stratum reinforcement and water flow sealing.
This product has high adhesion and good mechanical properties, and can maintain its long life on the working surface.
Grass can increase the reaction speed of the product by adding a certain amount of accelerator.
After being injected into the formation, the low-viscosity mixture remains in a liquid state for tens of seconds, penetrates into small cracks, and expands, thereby effectively
reinforcing and sealing the treated area.
Use of the product requires a pump and mixing gun.
Application fields
． Reinforce cracks in coal and rock mass
． Reinforcement of tunnels and mining faces
3. Advanced reinforcement of faults, fracture zones and collapse pillars
． Full-length anchoring of anchor rods and anchor cables
． Build a waterproof wall within a certain range
． Tunnel lining, dam structure reinforcement
