Filling and sealing series

Filling and sealing series This product is a liquid modified organic polymer resin material. It is a composite product composed of organic materials of two components: B and B. It is mainly used for filling the roof cavity of underground coal mine tunnels and filling between two sealing walls. The product is non-toxic, odorless and non-corrosive.
With special equipment for grouting, the resin component 8 and the curing agent component B are fully mixed at a volume ratio: And hardens quickly within minutes. It has fast foaming speed, multiple times, certain pressure-bearing capacity, good flexibility, shock resistance and compression resistance, good resilience, rapid accumulation and molding after foaming, low fluidity, low reverse temperature, and the cured product has It has great toughness, does not become brittle, cracks, or falls off, and has excellent sealing performance.
Product advantages
High curing elasticity, large pressure resistance
High fire resistance, strong flame retardant effect, antistatic
Rapid foaming, excellent sealing performance, less filling material
The reaction time and foaming multiple are adjustable, and the construction operation is simple, efficient and fast
Scope of application
Filling of coal and rock stratum roofing void areas, tunnel roofing, slab filling, abandoned tunnel filling
Filling gaps in coal and rock mass collapse in tunneling and coal mining faces
Permanently sealed, quickly establishing fireproof walls and temporary windshields
Quickly sealing underground toxic gases to prevent accumulation and leakage of harmful gases
