Detailed introduction

Product overview

YK-101 is a series of organic polymer two-component grouting materials, the slurry has good fluidity, can penetrate into the deep fine fractures of the rock formation, and can effectively strengthen the crushed surrounding rock and coal seam. It has the advantages of high strength, strong adhesion, adjustable solidification time and good toughness.

Product features

1. The curing time is adjustable, and the compressive strength of ordinary materials can reach more than 40mPa after curing.

2. Solvent-free, high flash point, flame retardant, no harmful gases.

3. It has good adhesion to the construction base surface such as rock formation and coal seam.

4. The consolidated body has good toughness, compression 20-30% is not brittle cracking, can fully adapt to the deformation of rock mass and coal seam, once consolidated, quickly strengthen the crushed matrix.

Scope of application

1. Coal wall grouting reinforcement to prevent sheet gang, fault crushing belt pre-grouting reinforcement to prevent roofing, small coal column reinforcement, pre-mining reinforcement, etc.

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