等离子弧已广泛用于不锈钢、铜、铝等难熔金属的切割,成为热切割领域中主要的技术手段之一。但是对于等离子弧在切割中产生的有害物质和必要的防护措施,往往被人们所忽视。等离子弧在切割过程中产生的有害物质有:金属烟尘、有害气体、光辐射、噪声、高频电磁场、放射性物质等,其中有害气体、金属烟尘和放射性物质的污染最为突出。现分述如下。有害气体中臭氧是呈淡蓝色气体,它比空气重约1.5倍,不易飘散。具有强烈的刺激性,浓度高时有腥臭味
Plasma arc has been widely used in stainless steel, copper, aluminum and other refractory metal cutting, thermal cutting has become one of the major areas of technology. However, the plasma arc in the cutting of harmful substances and the necessary protective measures, often overlooked. Plasma arc during the cutting process produces harmful substances: metal soot, harmful gases, optical radiation, noise, high-frequency electromagnetic fields, radioactive substances, etc., of which harmful gases, metal soot and radioactive material pollution is most prominent. Now is as follows. Ozone gas is light blue gas, it is about 1.5 times heavier than air, not easy to drift. Has a strong irritant, when the concentration is high stench
