喷砂于1940年推广到工业,广泛地应用于造船、石油装备、平台的制造和保养以及其他金属工业。其方法是用压缩空气喷出一股硅砂流准备适于以后处理用的清洁表面。喷砂时产生大量可呼吸硅尘,陡喷砂工人及与他们有关的工人发生矽肺。在密闭环境中喷砂时,增加可呼吸硅尘接触机会,对无防护者是特别危险的。 Sandblasting was extended to industry in 1940 and is widely used in shipbuilding, oil rigging, platform manufacture and maintenance, and other metal industries. The method is to use compressed air to spray a stream of silica sand to prepare a clean surface suitable for later processing. Blasting produces a large amount of breathable silica dust, steep blasting workers and their workers associated with silicosis. Blasting in a confined environment increases the chance of exposure to dust and dust, which is particularly dangerous to unprotected persons.
