臭氧层破坏成为当今全球环境问题之一,已引起世界各国的关注。1987年制定的关于消耗臭氧层物质的蒙特利尔协议,经1990年和1992年两次修正,控制措施更加严厉,一些新的物质也被列入名单,规定到1996年1月1日淘汰CFCs,对HCFCs也施加了控制。我国政府选择2010年完全淘汰方案,为中国实施破坏臭氧层物质逐步淘汰的最终方案。本文对CFCs替代进程、我国泡沫塑料行业实施逐步淘汰的技术路线以及美国环保局列出的安全的CFCs替代物作了介绍。
Destruction of the ozone layer has become one of the global environmental issues and has attracted the attention of countries in the world. The Montreal Protocol on Substances that Deplete the Ozone Layer, which was enacted in 1987, was revised twice in 1990 and 1992. Control measures have been more stringent. Some new substances have also been included in the list, requiring the phase-out of CFCs by January 1, 1996, for HCFCs. Control is also applied. Our government chose the complete phase-out plan in 2010 to implement the final plan for the phase-out of ozone-depleting substances in China. This article introduced the replacement process of CFCs, the phase-out technology of China’s foam industry and the replacement of safe CFCs listed by the US Environmental Protection Agency.
