What are the main application fields of Heptafluoropropane+HFC-227ea?
Heptafluoropropane (HFC-227ea is the abbreviation of heptafluoropropane), which is used in many fields of fire protection. It is mainly used to put out all kinds of fires, including electrical fires. Today's buildings, from the palace room to the palace hall, are mostly fortified. Electrical devices, such as computers in the computer room and communication equipment, are afraid of fire, and heptafluoropropane can be extinguished invisibly, without damaging the precision equipment and keeping it intact.
Furthermore, flammable liquid fires also depend on it to be extinguished. If you are in an oil depot and the oil is stored in a warehouse, if you are not careful, the fire will be difficult to contain. Heptafluoropropane can quickly reduce the temperature of oil, break the chain of combustion, and save the danger.
And in the prevention of combustible gas fires, heptafluoropropane is also very useful. In the place of gas, if it leaks and encounters fire, it will cause disaster for a moment. It can quickly inhibit the combustion reaction, stop the spread of fire, and protect the peace of the party.
And in the fight against fires on solid surfaces, it is also quite effective. Such as the pavilion of books, thousands of volumes of books, once the fire starts, heptafluoropropane can quickly rush to it, ensuring the integrity of the books and preventing the destruction of the books in Zhu Rong. As for the museum of cultural relics, the treasures are listed, and heptafluoropropane is used as a defense, which can protect the treasures of antiquities and keep
All of these are the focus of heptafluoropropane, which is indispensable in today's fire protection area, protecting the safety of people and money, and ensuring the integrity of things.
What is the fire extinguishing principle of Heptafluoropropane+HFC-227ea?
Heptafluoropropane (HFC-227ea), its fire extinguishing principle is as follows:
This product extinguishes the fire, and the first is cooling. Heptafluoropropane is sprayed on the fire and quickly gasifies. This process absorbs a lot of heat, causing the temperature of the combustion product to drop sharply. If the temperature drops below the ignition point, the fire will be difficult to continue, such as draining the bottom of the fire and extinguishing the flame.
Furthermore, heptafluoropropane will decompose at high temperatures to produce fluorine-containing free radicals. These free radicals are extremely active and can react with key free radicals in the combustion reaction (such as hydrogen and oxygen radicals, etc.), trapping them, thereby cutting off the combustion chain reaction. If the chain reaction cannot continue, the fire must be controlled, just like cutting weeds and eradicating roots, and the spread of fire stops.
In addition, the gas formed by heptafluoropropane covers the combustion area and can dilute the oxygen concentration. When the oxygen concentration drops to a certain level, the combustion conditions required for combustion are not available, and the fire gradually dies out, just like cutting off its support, the fire gradually dies. In this way, heptafluoropropane has multiple functions such as cooling, inhibiting chain reactions, and diluting oxygen to achieve the purpose of extinguishing fires.
How safe is Heptafluoropropane+HFC-227ea?
Heptafluoropropane is heptafluoropropane, which is the same substance as HFC-227ea. Its safety is quite high and it is reflected in many aspects.
In terms of fire extinguishing efficiency, heptafluoropropane is fast and efficient in fire extinguishing. It can suppress the flame in a short time, block the combustion chain reaction, quickly extinguish the flame, reduce the damage of the fire to the surrounding environment and equipment, and ensure the safety of personnel and property.
When it comes to toxicity, heptafluoropropane is very toxic to human body within the normal use concentration range. During the fire extinguishing process, a large amount of toxic and harmful substances will not be decomposed, and it will not cause serious poisoning to the on-site personnel, leaving ample time for the evacuation and rescue of personnel.
In terms of environmental impact, heptafluoropropane has an ozone depletion potential (ODP) of nearly zero, which has minimal damage to the atmospheric ozone layer and is in line with environmental protection concepts. At the same time, its greenhouse effect potential (GWP) is relatively low, its retention time in the atmosphere is short, and its impact on global warming is small.
In terms of physical properties, heptafluoropropane is colorless, odorless, and non-conductive. It will not cause corrosion and damage to electronic equipment, precision instruments, etc. It is suitable for protecting various important equipment and places, such as data centers, power distribution rooms, libraries, etc.
Furthermore, its storage and transportation are also safe. It is gaseous at room temperature and pressure, and is usually stored in a pressure vessel in liquid form. The storage equipment has a perfect safety design. As long as the relevant specifications are followed, the storage and transportation process is relatively safe and reliable. In short, heptafluoropropane is widely used in the field of fire protection due to its many safety characteristics.
What are the advantages of Heptafluoropropane+HFC-227ea compared to other fire extinguishing agents?
Heptafluoropropane is HFC-227ea, which is a clean gas fire extinguishing agent. Compared with other fire extinguishers, it has many advantages.
First, the fire extinguishing effect is excellent. This fire extinguishing agent can quickly suppress the flame, and by chemical inhibition, it can effectively interrupt the combustion chain reaction and quickly extinguish the fire. Its fire extinguishing speed is fast, which can contain the spread of the fire in a short time and minimize the fire loss.
Second, it is environmentally friendly. Its ozone depletion potential (ODP) is zero, it will not destroy the ozone layer, and the greenhouse effect potential value (GWP) is relatively low. It has a short retention time in the atmosphere and has little impact on global climate change, which is in line with the current environmental protection needs.
Third, clean and no residue. No residue and stains are left after extinguishing the fire, and it will not cause secondary pollution to the protected object. It is especially suitable for places with strict cleanliness requirements such as electronic equipment, archives, and precision instruments. After extinguishing the fire, the equipment can quickly resume normal operation.
Fourth, high safety performance. The fire extinguishing agent is basically non-toxic to the human body under normal use concentration, will not cause asphyxiation of personnel, and has good electrical insulation. It is suitable for fighting electrical fires and will not cause electric shock hazard due to the conduction of the fire extinguishing agent.
What are the precautions for storage and use of Heptafluoropropane+HFC-227ea
When storing and using heptafluoropropane (HFC-227ea is its English name), there are all kinds of taboos and should not be careless.
When storing, the first environment. Choose a cool, dry and well-ventilated place. If it is in a hot and humid place, or the ventilation is not smooth, the drug may be affected and its efficacy will be damaged. The temperature of the warehouse should be controlled in an appropriate area. It is not appropriate to be too cold or too hot. And the reservoir should be sturdy and intact to prevent its leakage. If there is leakage, one agent will be damaged, and the other may be safe.
When using it, be aware of its application. Heptafluoropropane is suitable for electrical, liquid and other fires. However, when applying it to a crowded place or a place sensitive to the medicine, it should be done with caution. When using it, the operation method is also the key. The equipment must be operated according to the standard procedure to spread the medicine evenly, so as to achieve the effect of extinguishing the fire. And the user should anticipate the emergency plan, and in case of an emergency, they can deal with it calmly. After extinguishing the fire, it is necessary to inspect the scene carefully to check whether there is any risk of re-ignition, and the residue of the medicine should be properly disposed of to avoid defacement of the environment. In this way, the storage of heptafluoropropane can be comprehensive and safe.
