Supply Guizhou A/B mining filler chemical filler chemical grouting material mine reinforcement material

When the polyurethane sealing agent is used in the mine, it is necessary to use a special grouting pump to operate. The components of the polyurethane sealing agent are injected at a volume ratio of: to produce a polymerization reaction to form a solid reinforcement filling.
- -:- The raw materials and components in the polyurethane sealing agent have low viscosity, which allows it to penetrate into the small cracks of the rock mass and foam to bond and strengthen the rock mass. Polyurethane sealing agent is suitable for quickly sealing gas holes and water injection holes of different depths, hole diameters and angles. Polyurethane sealing agent is a new sealing material that replaces cement and yellow mud. It is extremely easy to use and does not require complicated operations. It is very fast to seal holes. It is an ideal hole sealing material for sealing dense shallow holes in mining working surfaces.

- -:- The main performance characteristics of polyurethane sealing agent

- -:-,
Low viscosity easily penetrates into tiny cracks
- -: - ,
Extremely strong bonding ability and long-lasting strong adhesion

- -:- ,
Excellent flexibility and can withstand the movement of the strata after reinforcement

- -:- ,
Some products have large foams that can effectively isolate gas

- -:- ,
Some products have high mechanical strength to improve the bearing capacity of rock formations

- -:-,
Excellent flame retardant properties. (Polyurethane sealing agent)

- -:- The main function and application scope of polyurethane sealing agent

- -:-,
Reinforce broken coal ( Rock) roofs are reinforced in advance to prevent roof collapse during excavation and mining operations, ensuring the safety of workers and improving production progress.

- -:-,
Reinforce the coal pillars and broken coal pillars along the goaf to reduce coal pillars and air leakage in the goaf area to prevent natural fires in the goaf area.

- -:-,
Blocking the wellbore water flow reduces or eliminates water spraying or leakage from the wellbore wall to ensure the long-term safe use of the wellbore equipment.

- -:-,
Seal the gas drainage borehole to seal the cracks around the borehole to improve the effect of mine gas drainage.
