Description

Technical Field

[0001] The present invention relates to the technical field of charged fire extinguishing agents, and particularly to a charged fire extinguishing agent for extinguishing open flames and reducing temperature and a preparation method thereof. Background Art

[0002] Charged fire extinguishing agents such as perfluorohexanone and carbon dioxide have good electrical insulation properties and can be safely used in the charged state, avoiding the risk of electric shock to operators due to contact with the charged part. Perfluorohexanone is a colorless, odorless, and non-toxic liquid with extremely high fire extinguishing efficiency and environmental friendliness. It does not pollute the environment and does not leave any residues, meeting the requirements of modern industry for green and sustainable development. The perfluorohexanone fire extinguishing agent can quickly extinguish the fire source and achieve rapid and effective fire extinguishing by reducing the oxygen concentration and cooling the flame. Its fire extinguishing process will not cause secondary damage to electrical equipment and has extremely low residue. The perfluorohexanone fire extinguishing agent is suitable for fire protection of various electrical equipment, including key electrical equipment such as distribution cabinets and high-voltage distribution rooms. Its intelligent control system can automatically adjust the release amount and spraying direction of the fire extinguishing agent according to the fire situation to ensure the maximization of the fire extinguishing effect. The perfluorohexanone fire extinguishing device has a compact structure, is easy to install, and has a small workload for daily inspection and maintenance, suitable for long-term stable operation.

[0003] However, traditional charged fire extinguishing agents have the following disadvantages:

[0004] The by-products generated after the traditional charged fire extinguishing agent extinguishes the fire mainly include hydrogen fluoride and other free radicals, such as CF3·, CF2·, CFO·, etc. These by-products are generated when heated and decomposed, and may have a certain impact on the environment. Summary of the Invention
