硬质合金 制造和使用硬质合金而引起的疾病较少,但在加工过程中产生的金属粉末,对人体健康的危害却很大,许多金属粉末时常被用来制造硬质合金或烧结金属碳化物。最常用的是钨、钛、铬、钽以及铌,钒、钼铍也都加以利用。钴普遍地被用作粘结剂。 硬质合金(碳化钨)的生产,在第一次世界大战之后始于德国和美国,而第一次对健康危害的报道是1940年在德国发表的。报道了一个生产硬质合金仅两年的工厂,在27名工人中就有8名的肺部在X线照片上有病变。接着,1959年报道了1948～1949年696名、1956年335名硬质合金工人的体检结果,发现呼吸系统疾病的发病率很高,并且在许多工人中肺部
Carbide manufacturing and use of cemented carbide caused less disease, but in the process of producing metal powder, the human health hazards are very large, many metal powders are often used to make carbide or sintered metal carbide Things. The most commonly used are tungsten, titanium, chromium, tantalum and niobium, vanadium, molybdenum beryllium are also used. Cobalt is commonly used as a binder. The production of cemented carbide (tungsten carbide) began in Germany and the United States after the First World War, and the first report of a health hazard was published in Germany in 1940. Reported a factory that produced only cemented carbide for two years, and eight of 27 workers had lesions in the radiographs of their lungs. Then, in 1959, the physical examination results of 696 workers from 1948 to 1949 and 335 cemented workers in 1956 were reported and found to have a high incidence of respiratory diseases. In many workers, the lungs
