焊接防毒机能将焊接时所产生的金属蒸气及时吸收,通过集尘箱净化后,或未经净化直接排向大气,从而改善操作环境。近年来,随着使用低氢型焊条的逐渐增加,原来惯用的静电过滤防尘面罩已不能达到防毒的要求。特别是低氢焊条产生的金属蒸气中,对人体最有害的氧化钾(K_2O)和氟蒸气有75%未能被吸收。用能过滤微米以下粒子的高级滤层(如玻璃纤维),其价格贵,使用寿命短,尤其在夏天操作时
Welding anti-virus function will be welded metal vapor generated by the timely absorption through the dust box after purification, or without purification directly to the atmosphere, thereby improving the operating environment. In recent years, with the use of low hydrogen electrode gradually increased, the original static filter dust mask has been unable to meet the anti-virus requirements. In particular, metal vapor produced by low-hydrogen electrodes, 75% of K 2 O, which is the most harmful to human body, and fluorine vapor can not be absorbed. The use of advanced filters (such as glass fiber) capable of filtering particles under the micron range is expensive and has a short lifetime, especially during summer operation
