Water-based foam fire extinguishing agent is a dual function of cooling and chemical control. Fire-fighting foam liquid extinguishing agent can be used to fill various specifications of portable fire extinguishers and cart-type fire extinguishers.
Fluoroprotein foam fire extinguishing agent FP 3/6% is formulated on the basis of protein foam fire extinguishing agent with appropriate addition of fluorocarbon surfactant. Compared with protein foam fire extinguishing agent, because of its surface tension and interfacial tension is significantly reduced, the shear stress is small, the fluidity is good, the oleophobic ability is strong, the oil pollution resistance ability is high, so that the fire extinguishing agent has a rapid fire extinguishing time (extinguishing time Shorten 1/3 ~ 1/2), can use spraying method to fight large oil tank fire, can be combined with dry powder fire extinguishing agent and other advantages.
Aqueous film-forming foam fire extinguishing agent AFFF1/3/6% (also known as light water foam) is made up of hydrocarbon surfactants, fluorocarbon surfactants, cosolvents, stabilizers, antifreeze, preservatives, etc., and water . It is an efficient foam fire extinguishing agent with dual functions, high fire extinguishing efficiency, high speed, good re-ignition resistance and sealing performance, strong pollution resistance and long storage period.
Multifunctional low, medium and high foam fire extinguishing agent is widely used in underground tunnels, airports, underground oil depots, garages, ships, coal mines and limited space fire prevention and rescue. It is used to cover large areas of non-water-soluble flammable and flammable liquids. Can play its role better. Because the low, medium and high foam fire extinguishing agent is a low, medium and high general-purpose synthetic foam fire extinguishing agent, it is convenient to store, and storing one product can satisfy all fire fighting foam fire extinguishing systems and foam generators.
The foam fire extinguishing agent is rich in foam, delicate and strong in adhesion. Because the fluorocarbon composite surfactant is used in the formula, the foam time is long, the water separation time is stable, and the surface tension of the liquid water is low.
The water-based fire extinguishing agent disperses on the surface of the burned material and precipitates liquid to cool the surface, and forms a water film and a foam layer on the surface of the burned material to seal the surface of the burned material, isolate the air, form a heat insulation barrier, and vaporize the liquid after absorbing heat It also dilutes the oxygen content of the air on the surface of the burning material, which has a suffocating effect on the burning material and prevents the continuation of the combustion; the fire-fighting foam liquid extinguishing agent chemically reacts with the burning material to form a polymer material, which can reduce the burning of free radicals Produce, destroy the combustion chain and prevent combustion.
