This product is a liquid modified organic polymer resin material. It is a composite product composed of two groups of organic materials. It is mainly used for the reinforcement of coal and rock masses and the sealing of cracks. The two-component materials can react quickly after being mixed to form a high-strength, high-toughness polymer, cementing the original loose and discontinuous coal and rock mass into a continuous and complete stress-bearing body, with excellent bonding properties with the coal and rock formations. Good, after bonding, it has high compressive and shear strength, impact resistance, fatigue resistance, acid and alkali resistance. The material has low viscosity before reaction, good penetration and fluidity, and can penetrate well into the fine cracks of coal seams or rock formations. After reaction and solidification, it has good flexibility and can withstand the deformation of coal and rock formations. The product does not contain volatile solvents and does not produce toxic or harmful gases. When used, a pneumatic pump is used with a mixing gun to inject the two component materials into the coal and rock mass through drilling holes according to the weight ratio.
