Extinguishing agent
Perfluorohexanone is a liquid at room temperature, because its heat of evaporation is only 1/25 that of water, and its vapor pressure is 25 times that of water. These properties make it easy to vaporize and exist in a gaseous state. It mainly relies on heat absorption to achieve fire extinguishing. Effect. In terms of protecting the environment, it is a veritable green fire extinguishing agent.
Since the fire extinguishing concentration of perfluorohexanone is 4-6%, the safety margin is relatively high, and it is safer for the human body when used. Perfluorohexanone is a liquid at room temperature and is not a dangerous item. It can be safely stored and transported (including air transport) in a wide temperature range using ordinary containers under normal pressure, unlike other halon substitutes. It needs pressure vessel storage and transportation, but its boiling point is 48-49°C, and its use as a fire extinguishing agent still has certain limitations. It can be used as a replacement for halon 1211 fire extinguisher, or for total submerged systems and local applications for Class B fire protection. system.

Perfluorohexanone can be used as a wet cleaning agent for steam reactors and steam reactor components, as well as cleaning unwanted deposits accumulated in gas phase reactors, etching dielectric or metallic materials in gas phase reactors, and in gas phase reactors doped various materials.
There are various liquid chemical cleaning agents in practical applications, usually including various hydrocarbons such as acetone or isoacetone, and various fluorine-containing chemicals such as perfluorocarbons and perfluoronitrogen compounds. Water and hydrocarbons do not readily resolve fluoropolymer residues, in addition water requires long drying times, while hydrocarbons are flammable. Fluorine compounds are very stable and have the potential to contribute to global warming and are difficult to capture or treat with gas scrubbers. Perfluorohexanone overcomes the above shortcomings of traditional cleaning agents, has a significant cleaning effect and has little impact on the global warming trend.
solvent
The perfluoropolyether lubricant can be used as a coating on substrates such as magnetic media. After the coating is dried, the surface of the substrate is covered with a thin and uniform lubricating film. Perfluorohexanone can dissolve various perfluoropolyether compounds.
