When JD-MZH-1 type inhibitor according to the "Coal Mine Safety Regulations" provisions of Article 232, easily mined coal spontaneous combustion and spontaneous combustion, must take preventative filling of mined-out area. Prevent Spontaneous Combustion. Wong grout as an effective method for prevention of coal spontaneous combustion of a widely used, in order to improve fire prevention and grouting effect Wong, on the basis of long-term research on the prevention of coal spontaneous combustion, developed JD-MZH-1-type inhibitor. JD-MZH-1 type inhibitor has a variety of inorganic and organic materials, and its solution or join Wong coal slurry can be dipped into the layer, the joints and tiny cracks, but also adhere to the surface of coal, form a liquid film on the surface of coal, coal prevent contact with oxygen, reducing the oxidation of coal, oxygen barrier resistance of play to prevent spontaneous combustion of coal effect. Features: spontaneous combustion of coal retardant effect. Simple, no corrosion of equipment. Lower cost than similar products. Convenient storage and transportation.
