Detailed introduction

Product overview

YK-102 is an inorganic water glass system composite polymer two-component grouting material, which has good slurry fluidity and can penetrate into the deep fine fractures of the rock formation, which can effectively strengthen the crushed surrounding rock and coal seam. It has the characteristics of low internal temperature, large number of reactions without heat gathering, non-combustible.

Product features

1 Non-foaming reinforcement series, flow time adjustable within a certain range.

2. Under the condition of good mixing, the internal temperature of large-scale construction is low, which is especially suitable for construction on occasions with high temperature requirements.

3 Solvent-free, green raw materials, no harmful gases under normal construction conditions, flame retardant.

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, temporary reinforcement, etc.

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