Recommended fire equipment simple water-based fire extinguishers

After the water-based (water mist) fire extinguisher is sprayed, it becomes water mist, which instantly evaporates a large amount of heat in the fire field, rapidly reduces the temperature of the fire field, and inhibits heat radiation. The surfactant quickly forms a water film on the surface of the combustible to isolate oxygen and cool down. , Isolate the dual role, and participate in the fire extinguishing at the same time, so as to achieve the purpose of rapid fire extinguishing. Recommended simple water-based fire extinguishers for fire-fighting equipment-Hangzhou Zhonganxiao Technology Co., Ltd., Zhonganxiao Mall.

The fire extinguisher mechanism of water-based fire extinguisher is the principle of physical fire extinguisher. Fire extinguishing agents are mainly composed of hydrocarbon surfactants, fluorocarbon surfactants, flame retardants and auxiliary agents. Fire extinguishing agents have a penetrating effect on Class A fires, such as wood, cloth, etc. The extinguishing agent can penetrate inside combustibles. Even if the fire is large and cannot be extinguished, the part where the agent is sprayed can effectively block the fire source and control the fire. The spreading speed; it has an isolation effect on Class B fires, such as gasoline and volatile chemical liquids. The agent can form a long-term water film on its surface. Even if the water film is damaged by external factors, its unique fluidity can be Heals quickly and suffocates the flame. Therefore, water-based (water mist) fire extinguishers have flame retardancy that other fire extinguishers cannot match. Water-based fire extinguishers are not affected by indoor, outdoor, high wind and other environments, and the fire extinguishing agent can act on the surface of the burning material to a greater extent.

Water-based foam fire extinguisher

It is suitable for the initial fire fighting of flammable solids or liquids. It is widely used in oil fields, oil depots, ships, factories, shops and other places. It is an essential fire fighting equipment to prevent fires and protect people's lives and property. The water-type fire extinguisher is equipped with AFFF aqueous film-forming foam fire extinguishing agent and nitrogen. It has the advantages of simple operation, high fire extinguishing efficiency, no need to invert when used, long validity period, resistance to re-ignition, double fire extinguishing, etc., and can extinguish initial combustible solids and liquids It is a fire-fighting necessity for the development, processing, storage and transportation of wood, bamboo, fabric, paper and oil substances.

Principles of fire extinguishing

It is a physical fire extinguishing mechanism. The medicament can form and expand a thin water film on the surface of the combustible material to isolate the combustible material from the air and achieve fire extinguishing. Through the atomizing nozzle, a fine water mist is sprayed, spreading the fire field and evaporating heat, quickly reducing the temperature of the fire field, and at the same time reducing the oxygen concentration in the air in the combustion zone to prevent re-ignition. Good re-ignition resistance is an unparalleled advantage of water-based fire extinguishers.

Other uses

In addition to extinguishing fire, water mist fire extinguishers can also be used for self-rescue on fire scenes. In the event of a fire, spray the agent in the water mist fire extinguisher on the body and smear it on the head, which can completely avoid flame damage in ordinary fires and reduce burns to a large extent in high-temperature fire scenes.

Bottle color

Portable water mist fire extinguishers are different from traditional fire extinguishers. There are three colors of red, yellow and green to choose from. There are also nano-polymer materials on the top and bottom of the bottle body of the portable water mist fire extinguisher, which can emit light at night, so that the fire extinguisher can be found early in the evening when a fire occurs.
