Experimental Study Of The Inhibitor Performance Based On The Pyrolysis And Thermal Analysis Techniques

Fireproofing and Fire-extinguishing Technology Using Fire-retardant is widely used in many domestic coal mine, however, through searching a lot of literature, as well as to participating in the fire prevention projects during graduate, we found the majority of coal mine in the lack of theoretically retarder Fire Prevention guidance, the choice of retarder is blind、 random and have no target. They can not choose the most suitable retarder and the retarder spray process according to the characteristics of their own mine. Although many literature on the mechanism of retarder and retardant performance for the different ranks of coal are discussed, but more emphasis on qualitative analysis.Retarder have many kinds, magnesium chloride、calcium chloride、ammonium dihydrogen phosphate、calcium hydroxide were selected in the article. Coal sample selection is zhenghang mine coal15#coal、chenjiashan mine coal4-2coal and dingji mine coal11-2coal. First, using temperature-programmed instrument combined with gas chromatography to study the original coal sample and the gas production change of inhibition coal sample oxidation process. Second, using simultaneous thermal analysis to study thermogravimetric and thermal parameters change of oxidation process of coal samples, and calculate the kinetic parameters change according to the data curve. Finally, analysis of the two experimental results and know the law of inhabitation of experimental coal sample, give recommendations of how to using retarder to the three mine coal...
