Mine filling reinforcement material Malisan polyurethane

Mining reinforcement material is a two-component polymer slurry used to reinforce soft and broken rock formations that are prone to flaking coal walls. With its controllable expansion rate, high bonding strength and high safety of use, it plays an irreplaceable role in the reinforcement of surrounding rock.
The material is injected into the formation using double-liquid grouting at a
:
ratio. After injection, the low-viscosity liquid penetrates into the fine cracks and simultaneously expands and solidifies for the purpose of reinforcement.
Scope of use
Reinforce broken surrounding rock tunnels

Advanced reinforcement of the excavation working face to deal with roof collapse

Control the partial support of the mining working face
< br/>Reinforce the coal-rock triangle area.
Material Characteristics

Controllable expansion rate: Reduce the amount of material and at the same time play a self-emitting effect. Fully fill the cracks

Strong adhesion: quickly and firmly bond the coal seams

Low viscosity: easily penetrate into micro-cracks

High Toughness: enough to adapt to changes in rock formations

Reflect quickly, solidification: improve overall production efficiency.
