1991年大庆焊接培训中心与黑龙江省劳动保护科学技术研究所联合研制了全封闭式新型焊工培训间除尘系统,解决了焊工培训厂房烟尘治理的难题,为我国的焊接除尘工作开辟了一条新路。 1.焊接烟尘的危害“电焊烟尘”来自母材的只有10%~20%,大部分来自焊条药皮和焊芯,在焊条药皮和焊芯中同一元素转化成烟尘的几率相同,主要含有氧化锰、可溶性氟化物、臭氧、氧化物和铬镍等元素的氧化物。人体长期吸收过量的焊接烟尘后,会造成电焊尘肺、氟中毒、锰中毒等疾病。大庆油田焊接培训中心现有221m~2的培训厂房,培训工位30个。焊工培训大部分采用低
In 1991, Daqing Welding Training Center and Heilongjiang Institute of Labor Protection jointly developed a totally enclosed new type of welder training room dust removal system, which solves the problem of welding dust control in welder training workshops and opens up a new road for our country’s welding dust removal work. 1, the hazards of welding fumes “Welding fumes” from the parent metal, only 10% to 20%, mostly from the electrode coating and welding core, the same element in the electrode coating and welding core into the same probability of dust, mainly contains Manganese oxide, soluble fluoride, ozone, oxide, and chromium-nickel oxide. Long-term absorption of the human body after welding fumes, can cause welding dust, fluorosis, manganese poisoning and other diseases. Daqing Oilfield Welding Training Center existing 221m ~ 2 training plant, training station 30. Welder training is mostly used low
