摘要
为探求新型有效阻隔瓦斯爆炸装置,研究适合煤矿使用的抑爆材料,利用自行设计加工的断面为30cm×30cm方形爆炸实验管道,对不同参数的多孔泡沫铁镍金属材料的衰减超压效果分别进行了实验研究。实验结果表明,多孔泡沫铁镍金属具有一定的吸波能力,抗冲击性能较强,衰减管道内瓦斯爆炸冲击波效果良好,衰减率在12.9%～73.8%之间;孔径、相对密度及厚度是影响其衰减性能的重要因素,适当降低孔径、增加相对密度与厚度有利于提高多孔泡沫铁镍金属材料的衰减冲击波性能,而其中铁镍基体材料成分比例对其衰压效果影响不大。
To seek barrier device and develop explosion suppression material for coalmine gas explosion, effects of porous foam ironnickel metal material＇s attenuation of gas explosion overpressure on the different parameters was studied experimentally by using self-designed square experimental pipeline which section is 30cm × 30cm. The results show that the absorbing ability, strong capability of resisting impact, good effect on the attenuation of shock wave of gas explosion do the porous foam iron-nickel metal material have, attenuation rate is between 12.9% and 73.8%. Aperture, relative density and the thickness are important factors of attenuation performance. Properly reducing aperture and increasing relative density and thickness help to improve attenuation performance of porous foam ironnickel metal material, well the proportion of material composition has little effect on it.
