Tianjin mining spray material price Maosen mining spray material manufacturer product introduction:
The spray material is a two-component polymer slurry used to prevent spontaneous combustion of coal and isolate air to prevent gas leakage. With its high expansion rate, high adhesion and high safety, it sprays on the surface of the coal seam and simultaneously expands and condenses to achieve a sealing effect, playing an irreplaceable role in coal wall sealing.

Scope of application:
Coal pillar surface spraying to prevent harmful gas leakage caused by air leakage between the goaf and mining areas and the resulting coal seam Spontaneous combustion protection of the concrete shotcrete surface of the roadway and surface spraying of masonry sealed walls and coal wall cracks to prevent harmful gas leakage. Spraying on the surface of the tunnel to avoid large-area irregularities caused by gas during tunneling in coal mines. The leakage can greatly increase the safety of construction and can also be used to build rapid sealing walls.
Scope of use:
Close and expose the coal body to isolate the air to prevent spontaneous combustion of the coal body and gas leakage.
Material Features
. High expansion rate: reduce the amount of material. Strong adhesion: quickly and firmly bond the coal surface. Low viscosity: penetrate into micro gaps. High toughness: enough to adapt to rock formation movement.
