Where is water-based fire extinguisher better than other fire extinguishers? The following is an introduction to water-based fire extinguishers, and you will know everything about them.
1、 Fire extinguishing principle.
The foam generated by water-based film-forming foam extinguishing agent and nitrogen is sprayed onto the fuel surface, and the water extracted by foam forms a water film on the fuel surface, isolating the combustible from the air.
Water based fire extinguishers (water mist) are products in China that use the water mist logo and are green products promoted by the country. The fire extinguishing and fire prevention performance is ≤ 36KV, and the fine water mist fire extinguisher has broken the national standard.
2、 Product features.
Green and environmentally friendly, it can degrade 80% after fire extinguishing, and has outstanding flame retardant effect on surrounding equipment and space, and is resistant to re ignition; Quick fire extinguishing, strong breathability, capable of extinguishing deep fires.
3、 The fire extinguishing principle is a physical fire extinguishing mechanism.
This reagent forms and expands a thin water film on the surface of combustible materials, isolating them from the air and extinguishing the flame. The atomizing nozzle sprays fine mist, causing the fire to diffuse and heat evaporate. The temperature of the fire rapidly decreases, and the oxygen concentration in the air in the combustion zone decreases to prevent further combustion- Ignite. Good resistance to re ignition is an unparalleled advantage of dry powder fire extinguishers.
4、 Consider factors.
When the product is used for extinguishing electrical equipment, the extinguishing distance should not be less than 1M. After extinguishing the fire, the power must be cut off and the site cleaned. Do not invert or lay flat when using.
2. This product should be kept away from sunlight, rain, and high temperatures, and stored in a dry place.
3. After opening the water-based fire extinguisher, it must be refilled.
4. Reinflation and replenishment must be sent to a professional maintenance department, bottle body, and nozzle for hydraulic testing, and can only be used after passing the test.
Fifth, how to maintain the product.
1. The product should be replaced every three years. The main purpose of fire extinguishers is to be used in places with flammable solid substances, such as shopping malls, restaurants, office buildings, hotels, schools, and tourist and entertainment venues. And textiles, rubber, plastics, paper products, coal mines, etc.; It is also applicable to vehicles, ships, airports, stations, docks, gas stations and other Flammable liquid fire places (B fire); The fire risk of electrical equipment related to indoor and outdoor transformers, oil immersed switches, substations, etc. (E fire).
2、 Fire extinguisher characteristics:
(1) Clean environmental protection: Use clean water and environmentally friendly water-based fire extinguishing agents, which are non-toxic, odorless, and dust-free when extinguishing. It will not cause secondary pollution to the environment and will not destroy the ozone layer. This is environmentally friendly
(2) Convenient to use: The water mist sprayed during the fire extinguishing process has high visibility, which can reduce the smoke content and toxicity of the fire site, facilitate the evacuation of firefighters and firefighting, and is available for everyone to use. (3) Stable and reliable: the water mist extinguisher has a thin spray and good electrical insulation performance, up to 36kV, which can ensure that users of water-based extinguishers can extinguish electrical equipment or damage potential electrical fires (Class fire). 3. Fire extinguisher parameters: effective spraying time, s ≥ 15 effective spraying distance, m ≥ 3 spraying residual rate, percentage ≤ 8, high extinguishing level, capable of extinguishing Class A, Class B, and Class C fires, electrical insulation performance 36kV, operating temperature range, c0~+55
