Product description

1. Introduction

Coal mine water plugging polyurethane material (Gu Ant CM-13) is A kind of high strength, high toughness polymer light hard material, from coal mine water plugging polyurethane material A component (hereinafter referred to as "A component") and component B (hereinafter referred to as "B component") according to 1:1 volume ratio reaction. After the low-viscosity component A and component B are injected into the formation through the grouting device, they quickly penetrate into the micro-cracks, react, expand and solidify, and realize the bonding and sealing of water outlet cracks and pores.

After years of underground practice in coal mine, it has been proved that the polyurethane material used for water plugging in coal mine has permeable micro-crack. Strong cohesive force, fast adhesion of strata and loose coal rock mass; High elasticity, durable adhesion, adapt to the long-term impact of ground pressure, with good water plugging effect, is the best choice of underground coal mine water plugging material.

2. Material use

Waterproof coal pillar water plugging reinforcement;

♦ Dam seepage water treatment and structural reinforcement;

Coal mine shaft engineering water plugging;

♦ Coal and rock reinforcement.

3. Storage, packaging and precautions

1) Component A and component B have hygroscopic properties and must be stored in sealed containers isolated from moisture, stored in dry and cool places, away from heat sources, and strictly prevented from exposure to sunlight. Do everything possible to avoid dampness during operation.

2) Component A is 24kg/barrel, with A warranty of 6 months at room temperature.

3) Component B is 26kg/barrel, with a warranty period of 6 months at room temperature.
