To effectively suppress the transition of coal spontaneous combustion oxidation in goaf areas into the accelerated stage, a stable and high-heat-storage PCM was prepared using ammonium aluminum sulfate dodecahydrate and magnesium sulfate heptahydrate as raw materials. Through differential scanning calorimetry tests, solid-liquid transition tests, programmed heating tests, infrared spectroscopy, thermal insulation tests, and microscopic analysis, PCM thermal properties, the driving mechanism of solid-liquid transition, heat storage capacity, and coal oxidation inhibitory performance were studied. The test results show that the developed material has a phase transition temperature of 66.8℃, a latent heat of phase transition of 300.708 J/g, and a relatively low specific heat capacity during the heating process. The melting time exhibits an exponential decrease with increasing temperature, and a dense covering film forms after melting. When the material is added at a mass fraction of 15%, the inhibitory rate reaches 41%. Under a 500℃ heat source, with a material thickness of 30 mm, the effective thermal insulation time reaches 65 minutes.

为有效抑制采空区煤自燃氧化进入加速阶段,以十二水硫酸铝铵和七水硫酸镁为原料,制备性能稳定、储热量大的水合相变材料(PCM);通过差示扫描量热试验、固流转换试验、程序升温试验、红外光谱试验、隔热试验及微观分析等手段,分析材料的热学性能、固流转换的驱动机理、储热性及阻化性能。结果表明:所研发材料的相变温度为66.8 ℃,相变潜热为300.708 J/g,升温过程中具有较低的比热容;其融化时间随温度升高呈指数型下降,融化后可形成较为致密的覆盖膜;当材料添加量为15%时,阻化率达到41%;在500 ℃热源条件下,材料厚度为30 mm时,有效隔热时间可达65 min。

为有效抑制采空区煤自燃氧化进入加速阶段,以十二水硫酸铝铵和七水硫酸镁为原料,制备性能稳定、储热量大的水合相变材料(PCM);通过差示扫描量热试验、固流转换试验、程序升温试验、红外光谱试验、隔热试验及微观分析等手段,分析材料的热学性能、固流转换的驱动机理、储热性及阻化性能。结果表明:所研发材料的相变温度为66.8 ℃,相变潜热为300.708 J/g,升温过程中具有较低的比热容;其融化时间随温度升高呈指数型下降,融化后可形成较为致密的覆盖膜;当材料添加量为15%时,阻化率达到41%;在500 ℃热源条件下,材料厚度为30 mm时,有效隔热时间可达65 min。

To effectively suppress the transition of coal spontaneous combustion oxidation in goaf areas into the accelerated stage, a stable and high-heat-storage PCM was prepared using ammonium aluminum sulfate dodecahydrate and magnesium sulfate heptahydrate as raw materials. Through differential scanning calorimetry tests, solid-liquid transition tests, programmed heating tests, infrared spectroscopy, thermal insulation tests, and microscopic analysis, PCM thermal properties, the driving mechanism of solid-liquid transition, heat storage capacity, and coal oxidation inhibitory performance were studied. The test results show that the developed material has a phase transition temperature of 66.8℃, a latent heat of phase transition of 300.708 J/g, and a relatively low specific heat capacity during the heating process. The melting time exhibits an exponential decrease with increasing temperature, and a dense covering film forms after melting. When the material is added at a mass fraction of 15%, the inhibitory rate reaches 41%. Under a 500℃ heat source, with a material thickness of 30 mm, the effective thermal insulation time reaches 65 minutes.
