Problems solved by technology

[0003] In the prior art, chemical fire extinguishing agents are usually developed and configured for land fires, and are suitable for different types of fires. However, fires will inevitably occur on seawater facilities. When extinguishing fires in seawater facilities, since there are no fresh water resources at sea, existing fire extinguishing agents are usually used Fire extinguishing agent and seawater are used as diluents to extinguish fires. The disadvantage is that when sea water is used as diluent and fire extinguishing agent to mix fire, the fire extinguishing effect will be reduced. cost

Embodiment 1

[0014] Take by weighing 20 grams of hybrid fluorocarbon betaines, 20 grams of fluorinated alkyl betaines, 50 grams of n-octanol ether sulfonate, 2 grams of sodium carboxymethylcellulose, 50 grams of dodecyl betaines, 50 grams of cocamidopropyl betaine are dissolved in 808 grams of water, which is usually fresh water, stirred at high speed to make it evenly mixed to obtain the seawater foam fire extinguishing agent.

[0015] The seawater foam fire extinguishing agent is formulated into a seawater aqueous solution with a mass fraction of 6%, that is, the seawater fire extinguishing agent has a mass fraction of 6%, and the diluent seawater has a mass fraction of 94%. Fill it into MSJ950 water-based fire extinguisher to extinguish 13B gasoline fire. The fire extinguishing agent is sprayed onto the oil surface by the fire extinguisher, and the dense smoke turns into white water vapor immediately, and the fire is controlled within 6 seconds, has only a small flame within 8 seconds, ...

Abstract

The invention discloses a seawater fire extinguishing agent and application thereof. The seawater fire extinguishing agent is prepared from the following components in percentage by weight: 2%-5% of hybridized fluorocarbon betaine, 2%-5% of fluorinated alkyl betaine, 5%-15% of n-octyl alcohol ether sulfonate, 0.2%-0.5% of sodium carboxymethylcellulose, 5%-15% of dodecyl dimethyl betaine, 5%-15% of cocamidopropyl betaine and the balance being water. The seawater fire extinguishing agent can take seawater as a diluting agent and has a relatively good fire extinguishing effect.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a seawater fire extinguishing agent and its application. Background technique [0002] Fire extinguishing agents are roughly divided into physical fire extinguishing agents and chemical fire extinguishing agents according to different fire extinguishing mechanisms. Physical extinguishing agents include water, foam, carbon dioxide, nitrogen, argon and other inert gases. Physical fire extinguishing agents reduce the temperature of the combustion mixture while diluting oxygen and isolating combustibles. Chemical fire extinguishing agents inhibit combustion by inhibiting the chain reaction of free radicals in flames, mainly haloalkane fire extinguishing agents, dry powder fire extinguishing agents, etc. [0003] In the prior art, chemical fire extinguishing agents are usually developed and configured for land fires, and are suitable for different types of fires. H...
