Facts It's Essential To Be Informed On Aerosol Fire Extinguishing

What is Aerosol fireplace extinguishing
What is aerosol fire extinguisher? Aerosol hearth extinguishing technological innovation is a fresh style of fireplace extinguishing technologies made on The premise of armed service pyrotechnics.

The very first era of aerosol hearth extinguishing technological know-how was born inside our country, also referred to as smoke hearth extinguishing technological know-how, which started within the early sixties. It absolutely was accomplished by scientific scientists through the Tianjin Fireplace Research Institute of Community Safety, who independently made an automatic smoke fire extinguishing system, which is mainly accustomed to extinguish fires in school A, B, and C liquid storage tanks.

From the early 1980s, Along with the emergence of environmental protection difficulties of “halon fireplace extinguishing agent”, finding choices to halon became a vital investigate subject matter.

At the end of the eighties, Russian experts initially succeeded in investigating aerosol fire extinguishing technological know-how which will extinguish fires in a submerged method, which opened up a completely new way for halon substitution research. Subsequently, aerosol fire extinguishing technologies has captivated the attention of your Intercontinental Group, and international locations for example China, America, Australia, Malaysia along with other nations around the world have also begun investigate on new aerosol hearth extinguishing systems.

Generally speaking, aerosol is often a steady condition program shaped from the dispersion of high-quality strong or liquid particles in the gas. Skillfully, it refers to your colloidal method that uses fuel (usually air) given that the dispersion medium and sound or liquid particles as the dispersant.Popular aerosols in character—clouds, smoke, fog, etc.The dimensions from the particles in aerosols is usually within the get of ten-five to 10-1μm, which has fuel fluidity and might diffuse about obstacles.

The medicament from the aerosol fire suppression system gadget is strong, and the part emitted with the medicament through the oxidation-reduction response is aerosol. The 1st technology of aerosol hearth extinguishing technologies-smoke fire extinguishing know-how.

K-variety aerosol fireplace extinguisher, also known as potassium salt fireplace extinguishing know-how, is the next stage of the development of aerosol hearth extinguishing technologies, which started in the former Soviet Union from the mid-nineteen sixties. Our region began late In this particular regard, starting off within the early nineties.

In this type of aerosol making agent, potassium nitrate is principally utilized as the main oxidant. Its sprays have substantial hearth extinguishing performance, but as they comprise a great deal of potassium ions, Effortless to absorb dampness, forming a yellow and sticky robust alkaline conductive liquid movie, this material is rather damaging to Digital devices, so K-sort aerosol automatic fire extinguishing product cannot be used in electronic gear, precision devices and cultural relics Archive place. At the moment, the use on the market is step by step lowering.

The third-technology aerosol (S variety) is especially product of strontium salt as the key oxidant. As opposed to the next-technology potassium salt (K-style) aerosol, strontium ions will not take in humidity, tend not to kind a conductive solution, and will not likely result in damage to electrical products. In 2001, China Mobile Communications Company chosen the strontium salt aerosol (S-variety aerosol automated fireplace extinguishing device) produced by the organization following demanding inspection and verification to shield its interaction base stations as well as other areas Geared up with complex electronic products.

At the moment, strontium salt aerosol products and solutions happen to be applied in 1000s of engineering jobs, as well as third-era aerosol has grown to be Increasingly more accepted by customers

Aerosol fireplace extinguisher application range
a. Electrical hearth
Communication home, communication foundation station, electronic Computer system room, etcetera.;

Electrical fires in destinations that contains precision devices and equipment, for instance ability distribution rooms, generator rooms, cable interlayers, cable wells, cable trenches, and many others.

b. Solid area fire
Floor fire of combustible stable elements in spots exactly where combustible good resources are used or saved.

c. Liquid fire
Liquid fires in destinations in which diesel oil is created, used or saved (apart from -35 diesel), hefty oil, transformer oil, animal and vegetable oil and also other flammable liquids of Classification C; Right before extinguishing a gas hearth, the gasoline supply can be Slice off.

Aerosol fire suppression method application .

d. The S-variety aerosol fire extinguishing unit can not be accustomed to place out the subsequent fires
①Substances which might be oxidized devoid of air, including nitrocellulose, gunpowder, and many others.; active metals, such as potassium, sodium, magnesium, titanium, and so on.; compounds that could decompose by on their own, such as specified peroxides, hydrazine, and so forth. Metal hydrides, such as potassium fluoride, sodium hydride, etcetera. Normal substances, which include phosphorus. Sturdy oxidants, for example nitrogen oxide, fluorine, and so forth.

② Deep fire of combustible reliable elements.

③ Fire in crowded spots, including theaters, auditoriums, and many others.

④ Fire in locations with explosion hazard, for instance workshops with explosive dust.

⑤ Extremely-clean up natural environment, like pharmaceutical workshops, chip processing areas, medical rooms, and so forth.

Aerosol fire extinguishing Doing work theory
The 4 components of combustion: combustibles, oxidizer, temperature and uninhibited chain reaction. The fire extinguishing system of fireplace extinguishing gasoline is usually to remove a person or various in the four features of combustion.

The reliable hearth extinguishing agent from the S-style aerosol fireplace extinguishing product is commenced by electric power, and it undergoes redox response to variety a lot of agglomerated fireplace extinguishing aerosols, and its composition is principally N2, a small number of CO2, and metallic salt reliable particles.

Aerosol fire extinguishing system is as follows
System of endothermic cooling and fireplace extinguishing
Metallic salt particles absorb a large amount of heat at significant temperatures, and go through Bodily endothermic procedures which include thermal melting and gasification. The flame temperature is reduced after which radiated into the combustible combustion area for gasification of combustible molecules and vaporized combustible molecules. The warmth of pyrolysis of combustion molecules into free radicals will decrease, along with the combustion reaction velocity is going to be suppressed to a specific extent.
