【摘要】:結(jié)合遇水放出易燃?xì)怏w物質(zhì)危險性識別的實(shí)際經(jīng)驗,研制全自動化的遇水釋放易燃?xì)怏w物質(zhì)危險性檢測儀。介紹檢測儀的結(jié)構(gòu)設(shè)計、工作原理以及關(guān)鍵技術(shù)。采用微負(fù)壓差反饋收集技術(shù)實(shí)現(xiàn)化工產(chǎn)品遇水釋放氣體的精確收集和體積檢測,采用自動注水實(shí)現(xiàn)對注水體積的精確控制,避免注水體積對放氣速率檢測的影響。對88%代森錳鋅和鎂鋁粉兩種典型樣品進(jìn)行遇水放氣速率的測試,驗證設(shè)備的準(zhǔn)確性和穩(wěn)定性。研究水溫條件對化工產(chǎn)品遇水釋放易燃?xì)怏w速率的影響,結(jié)果表明,隨著水溫升高,反應(yīng)速率加快,鎂鋁粉遇水放氣速率逐步增大。
[Abstract]:Based on the practical experience in identifying the danger of combustible gas released by water, a fully automatic instrument for detecting the risk of combustible gas released by water is developed. This paper introduces the structure design, working principle and key technology of the tester. The micro negative pressure difference feedback collection technology is used to realize the accurate collection and volume detection of the gas released by water in chemical products, and the automatic water injection is used to realize the accurate control of the volume of water injection, thus avoiding the influence of the volume of water injection on the detection of the gas release rate. The degassing rate of 88% mancozeb and magnesium-aluminum powder was measured to verify the accuracy and stability of the equipment. The effect of water temperature on the rate of combustible gas released from chemical products by water was studied. The results showed that with the increase of water temperature, the reaction rate was accelerated, and the gas release rate of magnesia-aluminum powder was gradually increased.
