【摘要】：采用1.2 L哈特曼管爆炸装置分别对粒径小于54μm、74μm、150μm及大于150μm的戊唑醇粉尘进行测试。针对戊唑醇粉尘浓度及粒径范围对其最小点火能的影响,分别进行单因素试验,并对其危险性进行分级。结果表明,保持粒径小于150μm,环境温度为20℃,喷粉压力为0.7 MPa,在质量浓度100~1 300 g/m~3之间,戊唑醇粉尘的最佳敏感质量浓度ρ_m为983.71 g/m~3,此时的最小点火能为404.74 mJ。保持戊唑醇粉尘质量浓度为900 g/m~3,环境温度为20℃,喷粉压力为0.7 MPa不变,粒径小于54μm、74μm、150μm及大于150μm的戊唑醇粉尘的最小点火能分别为10 mJ、100 mJ、400 mJ和1 000 mJ以上。因此,判定戊唑醇粉尘最小点火能属于M2级,为特别着火敏感性。
[Abstract]:A 1.2 L Hartmann tube explosive device was used to measure tebuconazole dust with particle size less than 54 渭 m, 74 渭 m or more than 150 渭 m. According to the influence of the concentration and particle size range of tebuconazole dust on the minimum ignition energy, single factor tests were carried out, and the hazard was classified. The results show that the particle size is less than 150 渭 m, the ambient temperature is 20 鈩，
