Product Details
Perfluorohexanone fire extinguishing device
I. Fire Extinguishing Principle
The main way to extinguish the fire is to remove most of the heat in the fire site, that is, after the release of perfluorohexanone fire extinguisher, it forms a gaseous mixture with carrier gas N2, which is very easy to absorb or consume a large amount of heat, so as to quickly extinguish the flame temperature and achieve efficient fire extinguishing.
II. Main Advantages
1. Good environmental protection performance: green environmental protection gas;
2. High efficiency of fire extinguishing: low concentration of fire extinguishing can quickly extinguish fire;
3. Safety of use: No cases of low toxicity were found.
4. Good electrical insulation performance: no damage to insulators of ordinary wires and cables;
5. Quick cooling effect: fire extinguisher has unique cooling effect after spraying.
6. Fire extinguishing without residue: It volatilizes quickly after use and will not cause damage to precision instruments and antique paintings.
7. Storage and transportation at atmospheric pressure is safe: liquid at normal temperature, can be transported according to ordinary goods, easy to fill, transport and storage;
Electrical fire, solid surface fire, liquid fire and gas fire which can cut off gas source before extinguishing fire. 8. Extinguishable
