Mining Inhibitor

Surface spraying of coal underground creates an isolation film between the coal and air; it prevents contact with oxygen and stops spontaneous combustion of coal; the inhibitor solution can withstand high temperatures of about 800℃~1000℃; a stable, antioxidative, flame-retardant, water-containing film forms on the coal surface, fully wrapping coal particles to isolate oxygen and prevent fire.
