Binary fire-extinguishing agent composed of halocarbons and inert gases

摘要

C_3H_2F_3Br (1323) is a new kind of Halon replacements developed by our research group. In order to improve the disperse capability of 1323, nitrogen was mixed with 1323 to form the binary fire-extinguishing agent. In this work, the binary fire-extinguishing agent of nitrogen and 1323 was used in experiment and the fire extinguishing efficiency was discussed. In addition, the fire suppression mechanism was investigated and the fire-extinguishing concentration of nitrogen and 1323 was also studied.
