Polymer Foam Filling Material for Coal Mine Sealing - Ruinuo Filling Material (CT PF)

Product Description

This A/B two-component phenolic resin foam material consists of an A component (a mixture of phenolic resin aqueous solution, inorganic powder, and foam stabilizer) and a B component (composed of organic acid and phosphoric acid). During on-site application, the components are mixed in a 4:1 volume ratio using a two-component pneumatic grouting pump and specialized grouting gun. The product features low reaction temperature, rapid foaming expansion, high-toughness foam solidification with pressure resistance, flame retardancy, and high-temperature tolerance. It effectively fills voids in roof collapses, abandoned areas, and rock surfaces within sealed coal mine shafts, ensuring rapid sealing.

Performance characteristics

• Rapid high-multiplicity foaming and expansion
• Low reaction temperature, no safety hazards
• Excellent toughness of the foam body, with certain pressure resistance, does not crack under compression
• Flame-retardant, heat-resistant, and anti-static
• Fast, efficient, and simple to apply

Application Scope

• Rapid backfilling and sealing of roof collapse areas in mining faces, including support reinforcement for voided rock masses
• Filling and sealing of mined-out areas and abandoned voids
• Rapid construction of fireproof and gas-proof isolation walls at upper/lower corners of working faces
• Sealing coal-rock fractures to prevent air leakage
• Construction of temporary enclosed walls for various purposes
