补充资料:防毒面具
| 防毒面具 protective mask 保护人员呼吸器官、眼睛和面部,防止毒剂、生物战剂和放射性灰尘等有毒物质伤害的个人防护器材。按防护原理,可分为过滤式防毒面具和隔绝式防毒面具。①过滤式防毒面具。由面罩和滤毒罐(或过滤元件)组成。面罩包括罩体、眼窗、通话器、呼吸活门和头带(或头盔)等部件。滤毒罐用以净化染毒空气,内装滤烟层和吸着剂,也可将这2种材料混合制成过滤板,装配成过滤元件。较轻的(200克左右)滤毒罐或过滤元件可直接联在面罩上,较重的滤毒罐通过导气管与面罩联通。②隔绝式防毒面具。由面具本身提供氧气,分贮气式、贮氧式和化学生氧式3种。隔绝式面具主要在高浓度染毒空气(体积浓度大于1%时)中,或在缺氧的高空、水下或密闭舱室等特殊场合下使用。 除上述2 种防毒面具以外,许多国家还装备有各类特种防毒面具。它是在过滤式防毒面具的基础上更换滤毒罐内的吸着剂或改进局部结构而成。现代防毒面具能有效地防御战场上可能出现的毒剂、生物战剂和放射性灰尘。它的重量有的已减至0.6千克左右,可持续佩戴8小时以上,佩戴防毒面具后还可较方便地使用光学、通信器材和武器装备。 |
