通过对煤自燃的4个阶段的分析,针对化学吸附产生的中间分解过渡物质加以化学阻化抑制,设计了试验并分析结果。通过试验可以得出过硫酸钠阻化剂能抑制活性基团产生,同时增加稳定的醚类、甲基、羧酸类过渡物质的产生,有效地抑制了煤的自燃。
Based on the analysis of four stages of spontaneous combustion of coal, the chemical resistance of the intermediate decomposition transitional substances produced by chemical adsorption is deteriorated, and the experimental results are analyzed. It can be concluded through experiments that sodium persulfate retarding agent can inhibit the generation of active groups and increase the generation of stable ethers, methyl and carboxylic acid transition substances, and effectively suppress the spontaneous combustion of coal.
