 1.防团体屑末和化学溶液溅入眼及损伤面部的面罩,用轻质透明塑料制作,多用聚碳酸酯等塑料,罩面两侧及下端分别向两耳和下额下端朝颈部延伸,使面罩能更全面地包覆面部,以增强防护效果。

 
2.防热面罩除防热服中提及铝箔面罩外,也可用单层或双层金属网制成,但以双层为好,可使部分辐射被遮挡而在空气中散热。如能镀铬或镍,则可增强反射防热作用,并能防止生锈。
 
3. 金属网面罩也能防微波辐射。
 
 
4.电焊工用面罩,用一定的厚度的硬纸纤维制成,质轻,防热,并具有良好的电绝缘性面罩。

1. Face masks that prevent splashing into the eyes and damage the face with chemical solutions are made of light transparent plastic, and plastic such as polycarbonate is used. Both sides and the lower end of the cover extend to the two ears and the lower end of the lower forehead respectively. Allow the mask to cover the face more fully to enhance the protective effect.
2. In addition to the aluminum foil mask mentioned in the heat-proof suit, the heat-resistant mask can also be made of single-layer or double-layer metal mesh, but it is better to use double layers to allow some radiation to be blocked and heat in the air. If Chrome or nickel can be Plated, it can enhance the thermal protection of reflection and can prevent rust.
3. Metal mesh masks are also resistant to microwave radiation.
4. The electric welder's mask is made of a certain thickness of hard paper fiber, light, heat-proof, and has a good electrical insulation mask.
