1997年11月16日,《中国哈龙行业淘汰计划》在实施《蒙特利尔议定书》多边基金执委会第23次会议上得到原则通过,它标志着中国消防行业哈龙整体淘汰已正式启动。 哈龙灭火剂,即卤代烷灭火剂,目前常用的有二氟一氯一溴甲烷(1211),三氟一溴甲烷(1301)两种。哈龙灭火剂灭火过程主要是化学抑制过程,它能破坏燃烧的链式反应,阻止燃料和氧气通过化学反应聚集在一起,所以哈龙的灭火效率很高,并且对暴露人员危害很小,释放后对保护对象没有损害,也不需要进行清理,因此,哈龙广泛运用于计算机房、通讯机房、珍贵的历史文物和档案馆,也在军事上使用,如舰船、飞机、坦克,甚至用来保护总统的轿车,总之,从玩具制造商到汽车生产厂以及航天航空制造业都使用哈龙保护人员和产品的安全。
On November 16, 1997, the “China Halon Industry Phase-out Plan” was adopted in principle at the 23rd meeting of the Executive Committee of the Multilateral Fund for the Implementation of the Montreal Protocol. It marked that the overall halon of the halon industry in the fire service industry in China was officially launched. Halon fire extinguishing agent, that is, Halon fire extinguishing agent, there are two commonly used chlorodifluorobromochloromethane (1211), trifluorobromomethane (1301). Halon extinguishing agent fire extinguishing process is mainly chemical suppression process, it can destroy the chain reaction of combustion, to prevent the fuel and oxygen gathered together by chemical reaction, so the fire extinguishing efficiency of halon is very high, and the exposure of personnel is very small, release Therefore, halon is widely used in computer rooms, communication rooms, precious historical relics and archives, and is also used in military applications such as ships, aircraft, tanks and even used To protect the President’s car, in short, the use of halons from toy manufacturers to car manufacturers and aerospace manufacturing industries to protect the safety of people and products.
