为了研究高吸水性树脂(SAP)对煤的阻燃性能,通过实验测试了高吸水性树脂的防灭火特性,采用基于程序升温法的煤氧化自燃模拟系统对比分析了原煤与含有水或高吸水性树脂的混合煤样在氧化升温过程中的温度变化特点,以及氧化产物的生成变化规律。结果表明:高吸水性树脂不仅能够延长煤氧化升温时间,减小氧化升温的整体速率,还能明显抑制氧化产物的生成,使其生成的初始温度更高,生成量更少,从而发挥较好的阻燃效果。因此,高吸水性树脂可作为一种新型矿井防灭火材料加以研究和开发。
In order to study the fire-retardant properties of superabsorbent polymer (SAP) on coal, the fire-extinguishing properties of superabsorbent polymer were experimentally tested. The coal-based self-ignition coal-based simulation system based on programmed temperature method was used to analyze the relationship between raw coal and water- The characteristics of the temperature change of the mixed coal sample of the resin during the oxidation and the variation of the formation of the oxidation product were also analyzed. The results show that superabsorbent resin not only prolongs the time for coal oxidation, but also reduces the overall rate of oxidation and temperature, and also significantly inhibits the formation of oxidation products, resulting in a higher initial temperature and less formation of the coal, thus playing a better role The flame retardant effect. Therefore, superabsorbent can be researched and developed as a new kind of mine fire extinguishing material.
