Description

High-efficiency fire extinguishing agent containing polyethylene glycol

Technical Field

Background

Fire is one of the major disasters that most often, most commonly, threaten public safety and social development. In particular, crude oil, fuel oil and flammable liquid chemicals, once a fire breaks out, the fire is difficult to control. The existing fire extinguishing agents mainly comprise water, foam fire extinguishing agents, carbon dioxide fire extinguishing agents, dry powder fire extinguishing agents, fire control sand and the like, and the fire extinguishing agents have defects for extinguishing fires caused by combustible liquid.

The carbon dioxide extinguishing agent has certain limitation in use space, cannot be used in places with personnel, is easy to be frostbitten when being improperly used, and has strict requirements on the environmental temperature, so that the carbon dioxide extinguishing agent has a limited use range and cannot be widely used. The dry powder fire extinguishing agent is composed of ammonium carbonate salt or ammonium phosphate salt and superfine particles of auxiliary components, nitrogen or dry air is used as driving gas to be sprayed on the surface of fire to extinguish a series of fire, but because wind in the fine powder air has great influence on the fire extinguishing agent, the diffusion range is large, the escape is influenced by the sight, the pollution to the surrounding environment is great, the adhesion is strong and is not easy to clean, and the defects are gradually discovered and need to be improved. The water-based fire extinguishing agent is mostly fluorine-containing, PFOS contained in fluorine is not easy to decompose, has a certain carcinogenic factor, and is formally and clearly specified by the fire department of China to gradually cancel the PFOS-containing fire extinguishing agent within 3-5 years. The invention breaks through the defects of the traditional fire extinguishing agent under the background and innovates the fire extinguishing agent containing the polyethylene glycol.
