Product Introduction

It is an inorganic material compounded by specific processes, which consists of cement, mineral admixtures, high-performance admixtures, fine aggregates, fibers, etc. 

It can be used for the rapid construction of sealing, support, and beautification of various tunnels and roadways. It can prevent the weathering of surrounding rock, the deformation of surrounding rock, the corrosion of metal objects, and seal gas. It is sprayed on - site after being evenly mixed according to a specific water - cement ratio.

Performance Characteristics

Good crack resistance, impermeability, and sealing performance.

Strong corrosion resistance and reinforcement performance.

High durability with no shedding or chipping.

Easy to construct with low rebound.

Scope of Application

The closed - type (PT - B) series is applicable to: roadways in coal mines and non - coal mines, sealed walls, and working conditions such as air bridges, connecting roadways, gob - side entry retaining, and small coal pillars during the retreat of the working face. It is also suitable for special working conditions in municipal engineering, underground facilities, tunnels, subways, etc.

The reinforcement - type (PT - J) series is applicable to: development roadways and permanent support roadways in coal mines, non - coal mines, tunnels, and subways. It is also suitable for special working conditions such as broken surrounding rock and fracture zones in underground facilities, tunnels, and subways.

The protection - type (PT - F) series is applicable to: national defense projects, mountain reinforcement, and slope treatment. It is also suitable for working conditions in deep - mining mines and rock - burst mines.
