Experiment Study on Retarding Performances of Gel Fire Resistance Material
Abstract：In order to study the oxidized retarding performances and distinguishment of the polymer gel,sodium silicate,fly ash complex gel,loess complex gel and other gel material to the coal spontaneous combustion,a coal spontaneous combustion programmed temperature increasing test device was applied to the programmed temperature increasing test on the oxidization of coal samples with different gel fire resistance material treated.The analysis on the temperature increasing rate,CO production rate,oxygen consumption rate and spontaneous combustion parameter of each coal sample under the same test condition was applied to judge the retarding performances of each gel material.The test results showed that the gel material would have certain control effect to the coal temperature increasing rate,CO production rate and oxygen consumption rate.The analysis showed that each gel material could have good retarding effect than water.The retarding effect from good to poor in sequence would be including the polymer gel,sodium silicate,fly ash complex gel and loess complex gel.
