WebApr 16, 2013 · 1211（二氟一氯一溴甲烷的代号）灭火器的分子式是CF2ClBr，是目前国内使用量较大的一种卤代烷灭火剂。 1211灭火剂是一种低沸点的液化气体，具有灭火效率高，毒性低，腐蚀性小，久储不变质，灭火后不留痕迹，不污染被保护物，电绝缘性能好等优点。 WebDec 28, 2016 · The ODP is the ratio of the impact on ozone of a chemical compared to the impact of a similar mass of CFC-11. Thus, the ODP of CFC-11 is defined to be 1.0. Other CFCs and HCFCs have ODPs that range from 0.01 to 1.0. The halons have ODPs ranging up to 10. Carbon tetrachloride has an ODP of 1.2, and methyl chloroform's ODP is 0.11.
