The application principle of silicone oil in fire extinguisher dry powder is mainly based on its unique physical and chemical properties. Silicone oil, as a colorless, transparent, non-volatile and stable organosilicon compound, can significantly improve the fire extinguishing effect of dry powder extinguishing agent.
First, silicone oil can increase the adhesion and adhesion of dry powder on the surface of the fire source. In the fire extinguishing process, the dry powder extinguishing agent needs to quickly cover the fire source and isolate oxygen to achieve the purpose of fire extinguishing. The addition of silicone oil allows the dry powder to adhere more closely to the surface of the fire source, forming a solid isolation layer, effectively preventing the contact between oxygen and the fire source, thus controlling the spread of the fire.
Secondly, silicone oil can also improve the extinguishing temperature and fire extinguishing effect of dry powder. Under certain fire sources, such as condensed fire sources or large flames, dry powder may not be able to extinguish the fire quickly. The addition of silicone oil can significantly improve the heat resistance and fire extinguishing efficiency of dry powder, so that dry powder can still maintain its fire extinguishing performance at higher temperatures, so as to extinguish fires faster and more effectively.
In addition, silicone oil also has strong chemical stability and is not easy to react with other substances. This makes the application of silicone oil in the dry powder of fire extinguishers more safe and reliable, and will not reduce the fire extinguishing effect or produce harmful substances due to chemical reactions.
In summary, the application principle of silicone oil in fire extinguisher dry powder is to significantly improve the fire extinguishing performance of dry powder fire extinguishing agent by increasing the adhesion and adhesion of dry powder, improving the extinguishing temperature and fire extinguishing effect, and maintaining chemical stability. These characteristics make the dry powder fire extinguishing agent containing silicone oil have higher efficiency and reliability in dealing with various fires.
