Water-based fire extinguisher components Fire extinguisher tips

What is a water-based fire extinguisher? A water-based fire extinguisher is a fire extinguisher that is suitable for the suppression of flammable solids or water-insoluble liquids but it is not capable of fighting a live equipment fire. Widely used in oil fields, oil depots, ships, factories, shops and other places, what constitutes water-based fire extinguishers ?

Water-based fire extinguisher extinguishing principle is a physical fire extinguishing mechanism. The agent can form and expand a thin film of water on the surface of the combustible to isolate the combustible from the air and achieve extinguishing. Through the atomizing nozzle, a fine mist of water is sprayed to spread the fire field and evaporate the heat, rapidly reducing the temperature of the fire field, and at the same time reducing the concentration of oxygen in the air of the combustion zone and preventing re-ignition. Good resistance to re-ignition is an unparalleled advantage of dry powder fire extinguishers.
Water-based fire extinguisher composition:
Water-based fire extinguishers consist of four components: hydrocarbon surfactants, fluorocarbon surfactants, flame retardants, and additives. Now make a detailed introduction to these constituent agents.
Hydrocarbon surfactants: Surfactants (also known as amphiphiles), molecules consisting of hydrophilic and lipophilic components. Hydrophobic surfactants are hydrocarbon surfactants. Many of the more common surfactants are hydrocarbon surfactants.
Fluorocarbon surfactants: Compared to hydrocarbon surfactants, fluorocarbon surfactants are lipophilic and surfactants are hydrocarbon surfactants, and the other term is the non-polarity of hydrogencarbon surfactants. The groups (ie, the lipophilic moiety) are hydrocarbon chains, while the non-polar groups of the fluorocarbon surfactant are fluorocarbon chains.
Flame Retardant: As the name implies, it is mainly designed to hinder the flammability of polymer polymers. The preferred flame retardants are red phosphorus in non-halogen flame retardants. It has advantages such as less amount, high flame retardancy, low smoke, low toxicity, and wide range of uses.
Characteristics of water-based fire extinguisher (1) Clean and environmentally friendly: Due to the use of clean water and the addition of environmentally friendly water-based fire extinguishing agents, non-toxic, odorless, and dust-free residues are extinguished and will not cause secondary pollution to the environment and will not destroy the ozone layer. Is an environmentally friendly good product.

(2) Easy to use: The visibility of water mist sprayed during the fire extinguishing process can reduce the smoke content and toxicity in the fire field, which facilitates the evacuation of personnel and the extinguishing of fire fighting personnel. Everyone can use it.
(3) Safe and reliable: The water mist sprayed by the water mist fire extinguisher is very fine and has good electrical insulation performance, up to 36kV, which absolutely guarantees the user of the fire extinguisher to extinguish the fire in the electrical extinguishing equipment or destroy the potential electrical fire (Class A fire ) Security at the time.
Xiaobian conclusion: After reading the article, we have a more professional understanding of the composition of water-based fire extinguishers ? For more relevant knowledge, please continue to pay attention to this website information platform.
