【摘要】：為了研究鎂鋁混合粉中鋁粉質(zhì)量百分?jǐn)?shù)對(duì)最低著火溫度的影響,利用HY16429型粉塵云引燃溫度試驗(yàn)裝置和HY16430粉塵層最低著火溫度實(shí)驗(yàn)裝置測(cè)定鎂鋁混合粉的最低著火溫度。研究結(jié)果表明:鎂粉粒徑為1~10 mm,鋁粉粒徑為200~300目,在粉塵質(zhì)量0.5 g,噴塵壓力60 k Pa條件下,鎂粉塵云最低著火溫度為575℃,鎂粉塵層最低著火溫度為300℃;鋁粉塵云在1 000℃未著火,鋁粉粉塵層最低著火溫度為470℃;鎂鋁混合粉塵云最低著火溫度比粉塵層最低著火溫度高,粉塵層狀態(tài)比粉塵云狀態(tài)更容易著火。鎂鋁混合粉最低著火溫度隨著鋁粉質(zhì)量百分?jǐn)?shù)的增加而升高。
[Abstract]:In order to study the effect of the mass percentage of aluminum powder on the minimum ignition temperature, the minimum ignition temperature of mg / Al mixed powder was measured by HY16429 dust cloud ignition temperature test device and HY16430 dust layer minimum ignition temperature test device. The results show that the minimum ignition temperature of magnesium dust cloud is 575 鈩，
