High Temperature Resistant Sealing Gel Material (Fire Resistant) Type 2
High temperature resistant sealing gel material (fire prevention and extinguishing) type 2 is a filling fire extinguishing material for coal mines. It contains components A and B. The two components are mixed in a volume ratio of 1:1 and then foamed and sprayed. The reaction process does not release heat. The foam formed has a high water content and good flame retardancy. It can be used in the fields of filling and sealing of coal mines, prevention of fire and spontaneous combustion, etc.
High Temperature Resistant Sealing Gel (Fire Resistant) Material Type 1
The silicate-modified polyurethane material used for spraying to plug air leaks in coal mines has excellent adhesion, flame retardancy, water resistance, corrosion resistance, and a certain toughness. It can still plug air leaks and seal when deformed along with the rock layer and wall, and also has a certain reinforcement effect.
Silicate Modified Polyurethane Material For Spraying And Plugging Air Leakage In Coal Mines
The silicate-modified polyurethane material used for spraying to plug air leaks in coal mines has excellent adhesion, flame retardancy, water resistance, corrosion resistance, and a certain toughness. It can still plug air leaks and seal when deformed along with the rock layer and wall, and also has a certain reinforcement effect.
Phenolic Resin Foaming Material For Coal Mine Filling And Sealing
Phenolic resin foam material for coal mine filling and sealing has excellent flame retardant properties, high expansion ratio and low reaction temperature, and is particularly suitable for large volume filling.
Polyurethane Material For Water Shutoff At Coal Mine
The polyurethane material used for coal mine water plugging has extremely high strength, excellent bonding force and solvent corrosion resistance. In a water environment, the mixed resin can expand at a high rate and densely fill all gaps. It also has a certain toughness and can deform with the rock layer while maintaining the plugging effect.
Silicate Modified Polyurethane Materials For Coal Mine Reinforcement
The silicate-modified polyurethane material used to reinforce coal rock in coal mines has excellent compressive strength, adhesion, flame retardancy, and solvent corrosion resistance, and has a certain toughness. It can be smoothly cured and maintain good strength even in a water environment. It can deform with the rock formation while maintaining the effect of sealing and reinforcement.
