Perfluorohexanone fire extinguishing devices and aerosol extinguishing devices are two different types of fire extinguishing equipment, each with its own advantages and disadvantages.
Advantages of perfluorohexanone extinguishing devices include:
Environmental protection: perfluorohexanone is a synthetic non-ozone layer destructive greenhouse gas, which has no destructive effect on the ozone layer, no greenhouse effect, non-toxic and harmless, and meets the requirements of environmental protection.
High efficiency: Perfluorohexanone fire extinguishing agent is liquid at room temperature, has a low boiling point, and quickly vaporizes after heating, which can quickly reduce the temperature in the protected area.
Safety: The perfluorohexanone fire extinguishing device is equipped with a variety of starting methods, which can be selected according to the needs of the appropriate starting method, and at the same time, the requirements for environmental conditions are low, which can effectively protect the safety of people and property.
The advantages of aerosol extinguishing devices include:
High fire extinguishing efficiency: Aerosol fire extinguishing agent can quickly and effectively extinguish fires and has high fire extinguishing efficiency.
Environmental protection: Aerosol fire extinguishing agents are harmless to the environment and will not cause damage to the atmosphere.
Easy to operate: The aerosol fire extinguishing device is easy to operate and does not require complex start-up procedures.
In contrast, the disadvantages of aerosol fire extinguishing devices include:
After extinguishing the fire, a large amount of carbonate and metal oxide dust will be generated, which is not easy to settle, easy to hurt, scratch the disc surface and wear the connector, etc., which will cause pollution to the protected object and the environment after extinguishing the fire.
The carbonates in the product are very susceptible to forming "salt dew" with water on the surface of the protected object, and are particularly corrosive to aluminum and some steels.
The metal salts and metal oxides in aerosol particles have a certain conductivity, and the release temperature is too high, which is easy to cause short circuit in electrical equipment.
The aerosol fire extinguishing agent contains 40% solid particles, which directly affects the escape of personnel.
After spraying, the visibility in the protective area is extremely low, about less than 1, and the visibility of the fire field is less than 3, and it is easy to adhere to the surface of the equipment, and settle on the surface or inside of the protected item due to the action of the gravity field, and some can cause equipment failure.
