Description

Technical Field

[0001] The invention belongs to the technical field of fire extinguishing agent application, and in particular relates to an application method of a fire extinguishing agent. Background Art

[0002] As the name implies, fire extinguishing agents are substances that can effectively destroy combustion conditions and terminate combustion. There are many types of fire extinguishing agents, and the commonly used ones are water, foam, dry powder, carbon dioxide, etc. According to the different fire extinguishing methods, fire extinguishing agents can be divided into: physical fire extinguishing agents and chemical fire extinguishing agents. Among physical fire extinguishing agents, water is the most commonly used, most abundant, and most convenient liquid fire extinguishing agent. The main fire extinguishing effects of water are cooling and suffocation. Other physical fire extinguishing agents include carbon dioxide, inert gas, and dry powder. Among chemical fire extinguishing agents, halogenated fire extinguishing agents are the most widely used. Halogenated fire extinguishing agents are divided into liquid and gas. Halogenated fire extinguishing agents have high fire extinguishing efficiency, low toxicity, and low corrosion, but the cost is relatively high.

[0003] A Chinese patent discloses (CN107349553A) a method for using a low-temperature resistant premixed foam fire extinguishing agent, which mainly solves the problem that the fire-fighting agent cannot be used in a low-temperature environment after being mixed with water in the prior art. By adopting a low-temperature resistant premixed foam fire extinguishing agent, directly filling it in a fire extinguisher and a fire extinguishing device for use, the problem that the foam liquid cannot foam and extinguish fire in a low-temperature environment can be effectively solved. The fire extinguishing agent includes a depressant, a film former, a foaming agent, a penetrant, a foam stabilizer, and a preservative, and by mass percentage: a depressant 5%-20%, a film former 0.1%-1.0%, a foaming agent 0.5%-2.0%, a penetrant 0.05%-0.2%, a foam stabilizer 0.2%-1.0%, a preservative 0.1%-0.5%, and other additives 0.1%-0.5%, and the rest is deionized water. The technical solution solves the above problems well and can be used in low-temperature premixed foam fire extinguishing. Although the current application method of fire extinguishing agents can also play a role in extinguishing fires, the overall fire extinguishing agent cannot meet the good fire extinguishing effect in some special circumstances in actual application. For example, when a lithium battery catches fire, the fire source cannot be extinguished quickly, and the scope and area of ​​the fire extinguishing are not wide. The overall fire extinguishing effect is not good. There is an urgent need for an application method of fire extinguishing agents. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that although the current application method of fire extinguishing agent can also play a role in extinguishing fire, the overall fire extinguishing agent cannot meet the good fire extinguishing effect in some special circumstances in actual application. For example, when a lithium battery catches fire, the fire source cannot be quickly extinguished, and the scope and area of ​​the fire extinguishing are not wide, and the overall fire extinguishing effect is poor. A method for applying a fire extinguishing agent is proposed.

[0029] In S7, the data is analyzed and evaluated, and the evaluation results are divided into three levels: excellent, good and poor.
