PRI-SAFETY Brand Vermiculite Aqueous Suspension (VAS) lithium battery fire extinguishing agent
Introduction:
Vermiculite Aqueous Suspension (VAS) 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.
Vermiculite is a natural mineral, which is a hydrated layered aluminum iron magnesium silicate. It consists of thin, flat flakes containing microscopic layers of water. The chemical exfoliation of vermiculite produces microscopic, individual platelets that are freely suspended in water，form a stable suspension in water, and a small amount of special elements are added to Destroy burning free radicals to increase the fire-extinguishing performance. This suspension is atomized and sprayed onto the battery through a special mist nozzle to isolate, cool, and eliminate combustion free radicals to extinguish the fire and control the battery from re-ignition.
Application:
Fixed Fire System and Portable Fire Extinguishers For Lithium Battery.
Lithium battery failure can be caused by the following:
Physical impact or penetration
Overheating
Short circuits
Internal cell failure
Manufacturing defects
With the rise in technology that uses lithium batteries, comes the added risk of lithium battery fires. The consequences of lithium battery fires are severe, so having the right precautions in place is critical. PRI-SAFETY VAS Fire Agent offers a unique solution that can be used across a range of applications to effectively tackle the blaze.
Environmentally safe
Vermiculite is a naturally occurring mineral. It is chemically and physically inert, only releasing steam when exposed to raised temperatures. It is also non-toxic to humans, plant life and animals.
How it Work?
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 PRI-SAFETY VAS is evaporated, the vermiculite platelets begin to build up and the fire is brought under control.
Advantage of VAS Fire Agent
The PRI-SAFETY VAS fire agent is a unique product that provides a solution to the Lithium Battery Fire. Its exceptional performance includes the following:
Water content cools the fire source
Vermiculite platelets encapsulate the fuel source creating an oxygen barrier
The vermiculite film is not electrically conductive
PRI-SAFETY VAS can be applied as a fire break to prevent the propagation of fire
PRI-SAFETY VAS is environmentally friendly
