The application of hydrogen-containing silicone oil in the field of fire extinguishers is mainly reflected in improving the permanent fluidity, water repellency and moisture resistance of dry powder fire extinguishing agents, so as to ensure the normal operation of fire extinguishers and quickly extinguish fire sources. The following is a detailed description of the application of hydrogen-containing silicone oil in the field of fire extinguishers:
Dry powder fire extinguishing agent needs to keep its internal material fluid during long-term storage to ensure that the powder can be evenly sprayed when used. Hydrogen-containing silicone oil, as an effective additive, can significantly reduce the caking trend of fire extinguishing agent. Through its strong repulsion, the liquid film cannot form a film during the formation process, but shrinks into a ball, reducing the contact area between particles, so as to maintain the lasting fluidity of the fire extinguishing agent.
Hydrogen-containing silicone oil molecules contain a certain number of Si-H bonds, and the activity of these bonds makes it easy to cross-link. At the same time, its extremely strong hydrophobic group -CH3 can give the dry powder good water repellent ability. In the material grinding process of making dry powder, the fire extinguishing powder is usually coated with hydrogen-containing silicone oil, and is cured by thermal curing treatment or catalyst at room temperature, so that the cured silicone oil coating forms a hydrophobic film, so that the surface of the particle is hydrophobic and prevents moisture. This treatment significantly improves the moisture resistance of the fire extinguishing agent and ensures its stable performance during storage and use.
According to statistics, the global hydrogen-containing silicone oil market continues to grow and is expected to maintain a stable compound growth rate in the next few years. In the field of fire extinguishers, the application of hydrogen-containing silicone oil has also shown a growing trend. With the continuous progress of technology and the continuous expansion of market demand, the application prospect of hydrogen-containing silicone oil in the field of fire extinguishers will be broader.
In summary, the application of hydrogen-containing silicone oil in the field of fire extinguishers is of great significance to improve the permanent fluidity, water repellency and moisture resistance of fire extinguishing agents, and is one of the key factors to ensure the normal operation of fire extinguishers and the fire extinguishing effect.
