本文介绍一种用于呼吸道防护的新型轻便口罩。该口罩采用无纺布、高效滤膜、含炭泡沫塑料及压敏胶带等新材料制作。重量仅10克,吸气阻力为4.9～10.19帕(0.5～1.04毫米水柱),阻留效率(气溶胶或放射性落下灰粒子99％以上,气态放射性碘分子90％以上)高,密封性好、无侧漏、柔软、佩戴舒适。适于核战争条件下或核试验区使用,平时亦可在有放射性尘埃工作场所使用。
This article describes a new lightweight face mask for respiratory protection. The mask using non-woven, high efficiency filter, carbon foam and pressure-sensitive adhesive tape and other new materials. The weight is only 10 grams, the suction resistance is 4.9 to 10.19 Pa (0.5 to 1.04 mm water column), the retention efficiency (aerosol or radioactive falling ash particles more than 99%, gaseous radioactive iodine molecules more than 90%), good sealing, No side leakage, soft, comfortable to wear. Suitable for use under nuclear war conditions or nuclear test zones, and may also be used in workplace with radioactive dust.
