Polyurethane reinforcement material, Hebei Maosen polyurethane, excellent quality, excellent construction!

This product is a polymer chemical grouting reinforcement material that can quickly bond broken coal and rock strata. It is mainly used to reinforce broken coal and rock strata, seal gas cracks and seal small flow water leaks. This product does not contain volatile solvents and does not produce toxic substances. ,harmful gas. Through special grouting equipment, the resin component and curing agent component B are fully mixed at a volume ratio of: The coal and rock mass is cemented into a continuous and complete stress-bearing body. At the same time, it has good bonding performance with the coal and rock layer. After bonding, it has high compressive and shear strength, impact resistance, acid and alkali resistance. The material has low viscosity before reaction, good permeability and fluidity, and can penetrate well into the fine cracks of coal seams or rock formations. After reaction and solidification, it has good flexibility and can withstand the deformation of coal and rock formations to strengthen broken coal. Rock mass effect.
Product advantages:
, high compressive strength, adjustable reaction time
, high flash point, good flame retardancy, safe and environmentally friendly, and does not pollute water bodies.
Low initial viscosity, good fluidity and strong penetration.
The polymer has good toughness, is not brittle under compression, and can withstand the deformation of coal and rock formations.
, safe and reliable after injection into coal and rock mass.
Scope of application:
Reinforcement of roadways, coal pillars and coal walls.
, the roof of the excavation working face, the roof of the coal mining face, the coal wall, and the advanced support section are reinforced.
Tunnel repair and embankment reinforcement.
, geological drilling, gas fissure leakage sealing and reinforcement.
