Product description

Modified reinforcement material

This product is a two-component reinforced grouting material prepared from organic polymer and modified polymer. It has the characteristics of fast curing, high strength, good toughness, strong adhesion, low odor and non-combustible. It is suitable for rapid reinforcement and sealing treatment of broken coal seams and rock layers in coal mines, tunnels and tunnels with poor ventilation. The slurry is a two-component independent package, and the slurry is not required to be weighed at the site. As long as the A component and the B component are automatically mixed by a two-liquid pump at a ratio of 1:1 (volume ratio), grouting can be performed.

Characteristics

It can be cured in 1 to 2 minutes, and can reach the compressive strength of 30MPa or more in 4 hours.

2, no solvent, high flash point, non-combustible, especially suitable for construction in closed roadway.

3, no matter in dry, humid and watery environment, the slurry does not foam, and the curing and strength are not affected.

4, it is not easy to be diluted and dissolved in flowing water; the consolidated body still has high strength.

5, the solid body toughness is good, compression 20-30% is not brittle.

6. Convenient construction. There is no need to specialize the slurry on site. It can be grouted after being automatically mixed by the two-liquid proportional pump.

7. The reaction temperature performance index is much lower than other similar products, and the highest reaction temperature is ≤100 °C.

8, flame retardant performance is not flammable, antistatic performance is far superior to other products.

Scope of application

1. Stabilize and strengthen the surrounding rock of coal mine roadway to prevent surrounding rock gangs, roofing, water inrush, etc.

2. Reinforce and fill the broken and loose rock mass in tunnels, subways, tunnels, roadways and other projects.

3. Rapid filling and reinforcement of underwater defects and voids in buildings such as dams, dikes, seaports, wharves, and bridges.

4. Anti-seepage and reinforcement treatment of concrete cracks in subways, tunnels, mines and various tunnels.
