NMP在鋰電池涂布機工藝中監(jiān)測的重要性:
NMP-甲基吡咯烷酮,是一種以γ-丁內酯為原料,與甲胺縮合而成液體,揮發(fā)性、滲透性極強,PH值為7-9堿性,易燃易爆,在鋰電池生產(chǎn)中應用廣。在鋰電池電極制造過程中,涂布機漿料中的溶劑NMP經(jīng)加熱后會形成氣態(tài),NMP氣體有毒性,對人體有傷害。
另外,NMP與空氣混合時有爆炸的可能。因此NMP的監(jiān)測與回收不僅關系到電池生產(chǎn)企業(yè)的節(jié)能減排效益,更是攸關人員健康與生命**的頭等大事。
NMP特性:
分子式:C5H9NO ,分子量:99.1322,CAS號:872-50-4。無色透明油狀液體,微有胺的氣味。熔點-24.4℃。沸點203℃;150℃(30.66kPa);135℃(13.33kPa);81~82℃(1.33kPa)。閃點95℃。相對密度1.0260(25/25℃)。折射率nD(25℃)1.486。粘度(25℃)1.65mPa·s。能與水、醇、醚、酯、酮、鹵代烴、芳烴互溶。揮發(fā)度低,熱穩(wěn)定性、化學穩(wěn)定性均佳。大鼠口服毒性LD50=3914mg/kg, 兔子經(jīng)皮毒性LD50=8000mg/kg。
