1.国内外电厂使用矿物棉情况我国矿物棉生产是从五十年代后期开始发展起来的,六十年代初曾在电力、石油、船舶、化工、冶金、轻工方面应用。辽宁电厂在建设期间曾大量使用过矿物棉和玻璃棉作保温材料,其他电厂也曾在汽轮机缸体、阀门、管道及烟风道上使用。但由于没有成型的管壳和毡板等矿棉制品,施工不够方便,加上对施工人员引起刺痒,因此,几年来没有得到推广使用。 1. Domestic and foreign power plants use mineral wool The production of mineral wool in China began in the late 1950s. In the early 1960s, it was used in power, petroleum, marine, chemical, metallurgy, and light industry applications. During the construction period, Liaoning Power Plant had extensively used mineral wool and glass wool as insulation materials. Other power plants were also used on steam turbine blocks, valves, pipes, and smoke ducts. However, due to the lack of molded mineral shells and felts and other mineral wool products, the construction is not convenient, and it causes itchiness to construction personnel. Therefore, it has not been popularized for several years.
