Abstract

The invention relates to the field of firefighting extinguishing materials, in particular to a novel CFA gaseous extinguishing agent and an extinguishing system thereof. The novel CFA gaseous extinguishing agent consists of 20 to 30 parts by weight of trifluoromethane, 10 to 20 parts of hexafluoroethane, 4 to 8 parts of octafluoropropane, 3 to 5 parts of nitrogen, 4 to 8 parts of sodium hydrogen carbonate powder, 2 to 5 parts of argon, 3 to 6 parts of heptafluoropropane and 1 to 2 parts of absorbent. The invention aims at overcoming the technical defects of the existing aqueous film forming foam extinguishing agent and providing the environment-friendly foam extinguishing agent. The novel CFA gaseous extinguishing agent has the characteristics that the extinguishing agent is good in foam forming effect, long in adhesion time and small in environmental pollution; and the CFA is used as the extinguishing agent, by adding the nitrogen and argon, a great amount of gas can be produced whenin use to effectively insulate the contact of the oxygen and an inflamer, the extinguishing capability of the extinguishing agent can effectively improved, the extinguishing time is shortened, and theenvironmental friendliness can be improved.

Description

technical field [0001] The invention relates to the field of fire extinguishing materials, in particular to a novel CFA gas fire extinguishing agent and a fire extinguishing system thereof. Background technique [0002] Halon fire extinguishing agent has many advantages such as fast fire extinguishing speed, less dosage, easy vaporization, total submersion, cleanliness, non-conductivity, and no deterioration in long-term storage, so it has a wide range of applications. It can be used to fight flammable gas fires, flammable liquid fires, flammable solid fires and electrical equipment fires. Since Halon fire extinguishing agent does not leave traces and does not pollute the burning material after extinguishing a fire, it is an ideal fire extinguishing agent for extinguishing fires in computer rooms, libraries, archives and precision instrument rooms. [0003] However, chlorofluorocarbons have certain toxicity, and generally the fewer chlorine atoms, the less toxic. Perfluoro...
