Exactly what is Aerosol fireplace extinguishing
Exactly what is aerosol fire extinguisher? Aerosol fire extinguishing technologies is a brand new type of fireplace extinguishing technological innovation formulated on The idea of armed service pyrotechnics.

The 1st generation of aerosol fireplace extinguishing technologies was born within our region, also known as smoke fire extinguishing technological innovation, which started from the early sixties. It had been concluded by scientific researchers through the Tianjin Hearth Investigate Institute of Public Stability, who independently produced an automatic smoke fireplace extinguishing procedure, which is especially utilized to extinguish fires in Class A, B, and C liquid storage tanks.

From the early nineteen eighties, With all the emergence of environmental security issues of “halon fireplace extinguishing agent”, locating alternatives to halon grew to become an important research topic.

At the conclusion of the 1980s, Russian scientists initially succeeded in researching aerosol fire extinguishing engineering which will extinguish fires inside of a submerged fashion, which opened up a completely new way for halon substitution investigation. Subsequently, aerosol fireplace extinguishing technological innovation has attracted the eye on the Global Group, and nations for instance China, the United States, Australia, Malaysia and various nations have also begun investigate on new aerosol fire extinguishing systems.

Generally speaking, aerosol is usually a stable point out system fashioned from the dispersion of wonderful sound or liquid particles inside of a fuel. Skillfully, it refers to a colloidal program that works by using gasoline (normally air) as the dispersion medium and sound or liquid particles as the dispersant.Common aerosols in nature—clouds, smoke, fog, and so forth.The scale on the particles in aerosols is generally from the order of 10-5 to ten-oneμm, which has fuel fluidity and will diffuse about hurdles.

The medicament inside the aerosol fireplace suppression process gadget is solid, along with the component emitted via the medicament in the oxidation-reduction reaction is aerosol. The first era of aerosol hearth extinguishing technologies-smoke fire extinguishing technology.

K-style aerosol hearth extinguisher, also known as potassium salt fire extinguishing technologies, is the second phase of the development of aerosol fireplace extinguishing technological innovation, which started in the former Soviet Union during the mid-nineteen sixties. Our nation started off late In this particular regard, starting up while in the early 1990s.

In such a aerosol making agent, potassium nitrate is especially utilized as the principle oxidant. Its sprays have large fireplace extinguishing efficiency, but mainly because they incorporate a large amount of potassium ions, Simple to soak up humidity, forming a yellow and sticky powerful alkaline conductive liquid film, this compound is incredibly detrimental to electronic products, so K-style aerosol computerized fire extinguishing device cannot be used in electronic gear, precision instruments and cultural relics Archive area. At the moment, the use available in the market is progressively reducing.

The 3rd-generation aerosol (S type) is principally made of strontium salt as the leading oxidant. Contrary to the second-era potassium salt (K-style) aerosol, strontium ions never absorb humidity, tend not to kind a conductive Option, and won't bring about damage to electrical gear. In 2001, China Mobile Communications Corporation selected the strontium salt aerosol (S-variety aerosol automated fireplace extinguishing device) made by the corporate after strict inspection and verification to protect its conversation base stations and various areas equipped with advanced Digital equipment.

At this time, strontium salt aerosol products are actually used in 1000s of engineering projects, along with the third-technology aerosol is becoming A lot more accepted by consumers

Aerosol fire extinguisher application selection
a. Electrical fireplace
Conversation place, communication base station, Digital Pc area, etcetera.;

Electrical fires in places made up of precision devices and machines, for example ability distribution rooms, generator rooms, cable interlayers, cable wells, cable trenches, and so on.

b. Strong surface area fireplace
Surface fire of combustible sound resources in spots where combustible good elements are employed or saved.

c. Liquid fire
Liquid fires in spots the place diesel oil is generated, utilized or stored (except -35 diesel), hefty oil, transformer oil, animal and vegetable oil as well as other flammable liquids of Category C; Before extinguishing a gas fireplace, the gasoline resource might be Slash off.

d. The S-style aerosol fire extinguishing product cannot be used to put out the subsequent fires
①Substances that can be oxidized without air, such as nitrocellulose, gunpowder, and many others.; active metals, for example potassium, sodium, magnesium, titanium, and so forth.; compounds that can decompose by themselves, like sure peroxides, hydrazine, etc. Steel hydrides, for example potassium fluoride, sodium hydride, and many others. All-natural substances, such as phosphorus. Sturdy oxidants, for instance nitrogen oxide, fluorine, etcetera.

② Deep fireplace of combustible sound materials.

③ Hearth in crowded spots, like theaters, auditoriums, etc.

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

⑤ Extremely-clean up atmosphere, like pharmaceutical workshops, chip processing destinations, health care rooms, and so forth.

Aerosol fire extinguishing Doing work basic principle
The 4 things of combustion: combustibles, oxidizer, temperature and uninhibited chain response. The fireplace extinguishing system of fire extinguishing gas is to eradicate just one or a number of with the four factors of combustion.

The strong fire extinguishing agent during the S-sort aerosol fire extinguishing product is started by electricity, and it undergoes redox response to variety a lot of agglomerated fire extinguishing aerosols, and its composition is principally N2, a small quantity of CO2, and metallic salt stable particles.

Aerosol fire extinguishing mechanism is as follows
Mechanism of endothermic cooling and fireplace extinguishing
Metal salt particles soak up a great deal of warmth at high temperatures, and bear physical endothermic processes including thermal melting and gasification. The flame temperature is lowered and after that radiated into the combustible combustion floor for gasification of combustible molecules and vaporized combustible molecules. The heat of pyrolysis of combustion molecules into free radicals will decrease, along with the combustion response speed will probably be suppressed to a specific extent.
