【摘要】：采用1.2 L哈特曼管爆炸裝置分別對粒徑小于54μm、74μm、150μm及大于150μm的戊唑醇粉塵進行測試。針對戊唑醇粉塵濃度及粒徑范圍對其最小點火能的影響,分別進行單因素試驗,并對其危險性進行分級。結(jié)果表明,保持粒徑小于150μm,環(huán)境溫度為20℃,噴粉壓力為0.7 MPa,在質(zhì)量濃度100~1 300 g/m~3之間,戊唑醇粉塵的最佳敏感質(zhì)量濃度ρ_m為983.71 g/m~3,此時的最小點火能為404.74 mJ。保持戊唑醇粉塵質(zhì)量濃度為900 g/m~3,環(huán)境溫度為20℃,噴粉壓力為0.7 MPa不變,粒徑小于54μm、74μm、150μm及大于150μm的戊唑醇粉塵的最小點火能分別為10 mJ、100 mJ、400 mJ和1 000 mJ以上。因此,判定戊唑醇粉塵最小點火能屬于M2級,為特別著火敏感性。
[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，
