style="text-indent:25px">防毒面具主要依靠濾毒罐防毒，其中的裝填物由吸附劑層和過濾層構(gòu)成，其中吸附劑層濾除有毒氣體和蒸汽，過濾層則過濾有害氣溶膠。因?yàn)閷?duì)蒸汽狀毒劑的吸著和對(duì)有害氣溶膠的過濾過程不同，防毒原理也不同。吸附劑層的防毒原理吸附劑層中，用的是載有催化劑的活性炭，即浸漬活性炭，這種經(jīng)過活化處理的無定形炭是多孔吸附劑，主要成分是碳，含量約為80%～98%，另有少量灰分?；钚蕴康目紫兑话惴譃槲⒖?、過渡孔、大孔3類，有時(shí)過渡孔也稱為中孔。微孔較小，有效半徑0.5～1納米，上限為1.5納米，所占的全部容積約為0.15～0.5厘米3/克。由于這類孔小而數(shù)量多，所形成的比表面積約占活性炭比表面積總數(shù)的90%以上，活性炭對(duì)毒劑蒸氣的吸附主要靠它。因此微孔的多少和分布在很大程度上決定某種特定活性炭的吸附能力。在吸附過程中，這三種孔隙互相連通，微孔在內(nèi)，過渡孔和大孔在吸附過程中起通道作用。過渡孔和大孔表面載有銅、銀、鉻或鉬、鋅等金屬氧化物，它們的加入數(shù)量對(duì)防毒性能影響較大。</p><p
