FIRE PROTECTION TO PREVENT PROPAGATION OF HEAT
Renuka Fire’s – EXTINGUISHER -AVD Lithium-ion batteries are popular because of how much power they can put out at a given size and weight in comparison to old lead type batteries. However, lithium-ion batteries are extremely sensitive to high temperatures and inherently flammable. These battery packs tend to degrade much faster than they normally would, due to heat. If a lithium-ion battery pack fails, it will burst into flames and can cause widespread damage.
Aqueous Vermiculite Dispersion AVD Fire Extinguisher
AVD Fire Extinguisher agent is an aqueous dispersion of chemically exfoliated vermiculite. It is applied to lithium battery fires as a mist, extinguishing them and preventing the propagation of the fire.
Renuka Fire’s Lithium-ion Battery fire extinguisher with AVD agent provides effective lithium battery fire protection to prevent the propagation of heat when applied as a mist. The AVD coating also acts as a fire break. The vermiculite particles within the mist are deposited on the surface of the burning fuel to create a film over the top of the fire.
The film instantly dries and, because the high aspect ratio platelet particles overlap and bind together, a non-flammable oxygen barrier between the fuel and the atmosphere is produced. This process has a cooling effect on the fuel source and, as the water content in AVD is evaporated, the vermiculite platelets begin to build up and the fire is brought under control.
