What is the scope of application of 1211 Extinguishant?
1211 fire extinguishing agent is a type of halogenated alkane fire extinguishing agent. Its application range is quite wide. In fires caused by flammable liquids, such as gasoline, kerosene, diesel oil, etc., 1211 fire extinguishing agent can quickly play a role. Cover because it can inhibit the chain reaction of combustion, so that the flame can be quickly extinguished.
For flammable gas fires, if natural gas, gas, etc. accidentally catch fire, 1211 fire extinguishing agent is also effective. This agent is sprayed on the fire scene, which can instantly reduce the concentration of active free radicals in the combustion area and block the continuation of combustion.
Electrical equipment fires, such as transformers, motors, electrical switchgear fires, etc., 1211 fire extinguishing agent is particularly suitable. Due to its good insulation properties, when applied to electrical fires, it will not cause the risk of electric shock, and it can be efficiently extinguished to protect electrical equipment from greater damage.
In addition, in the fire insurance of precision instruments, archives, cultural relics and other places, 1211 fire extinguishing agent is also the best choice. It does not leave traces after extinguishing the fire, and will not cause secondary damage to precision instruments, precious archives and cultural relics, etc., and can be fully protected.
However, 1211 fire extinguishing agent has a destructive effect on the atmospheric ozone layer. According to relevant international conventions, it has been gradually restricted or even banned. Although its scope of application is clear in the past, in order to protect the earth's environment, it is necessary to find more environmentally friendly alternative fire extinguishing materials.
1211 Extinguishant fire extinguishing principle is what?
1211 fire extinguishing agent is a kind of halogenated alkane fire extinguishing agent, and its fire extinguishing principle is quite exquisite. This fire extinguishing agent will rapidly decompose at high temperature of the flame, releasing free radicals of halogen elements. This free radical is extremely active and can react in a chain with active radicals generated during combustion. Specifically, combustion reactions rely on active free radicals to continuously transfer energy and initiate reactions. The free radicals released by 1211 fire extinguishing agent can combine with these active free radicals, thereby interrupting the chain reaction of combustion. It is like cutting off the interlocking chain, so that the combustion reaction cannot continue. At the same time, when 1211 fire extinguishing agent is thermally decomposed, it will absorb a lot of heat, reduce the temperature of the combustion area, and make it difficult for the temperature of combustible materials to be maintained above the ignition point. Furthermore, the gas produced by the decomposition of 1211 fire extinguishing agent will form a protective film on the surface of the combustion object, isolating the contact between oxygen and combustible materials, as if building a barrier, so that oxygen cannot support combustion, so as to achieve the purpose of fire extinguishing. This fire extinguishing agent has many advantages such as high fire extinguishing efficiency, fast speed, and no traces, and is often used to fight all kinds of flammable, flammable liquids, gas fires, and electrical equipment fires.
What are the advantages of 1211 Extinguishants?
1211 fire extinguishing agent has many advantages. It has the ability to extinguish fire efficiently, and when it is extinguished, it can quickly stop the flame, which is effective. In case of sudden fire danger, it can quickly extinguish the fire and protect the safety of property and human life.
And its insulation is good, suitable for fire insurance of electrical equipment. In today's world, electrical equipment is abundant, and if you are not careful, it is easy to cause fires. 1211 fire extinguishing agent in this situation not only extinguishes fire but also does not damage equipment, prevents the danger of leakage and electric shock, and protects electrical equipment comprehensively, so as not to cause equipment waste due to fire extinguishing, reducing economic damage.
Furthermore, its impact on the environment is slight. Compared with other fire extinguishing agents, 1211 fire extinguishing agent in the atmosphere for a short time, will not accumulate for a long time and harm the environment. After extinguishing the fire, it dissipates quickly, leaving less residue, does not pollute the surrounding objects, and does not cause major disturbance to the ecological balance.
And its corrosiveness is weak. After extinguishing the fire, it will not seriously corrode the objects it touches, such as buildings, equipment, etc. This can ensure the quality of the object, prolong its use period, and save the cost of repair and replacement. 1211 fire extinguishing agent has many advantages in fire extinguishing.
What are the disadvantages of 1211 Extinguishants?
1211 fire extinguishing agent is also a commonly used fire extinguishing agent in the past. However, it also has various drawbacks.
First, this agent contains halides. After decomposition in the atmosphere, halogen atoms will destroy the ozone layer, causing the risk of ozone layer hole, endangering the earth's atmospheric protective barrier, and the safety of the global ecological environment.
Second, when 1211 fire extinguishing agent decomposes at high temperature, it will produce toxic and harmful gases, such as hydrogen halides. These gases not only damage the respiratory organs of the human body, but also cause poisoning and other hazards during the evacuation and rescue of personnel at the fire scene, and also cause pollution to the environment around the fire.
Third, the manufacturing, storage and use costs of 1211 fire extinguishing agent are high. Its manufacturing process is complex, the required raw materials are rare, and the storage conditions are harsh. It requires specific containers and environments to ensure its stability, which increases the cost of use. In large-scale fire extinguishing applications, economic considerations are particularly unfavorable.
Fourth, 1211 fire extinguishing agent has been banned or restricted in many countries due to the above drawbacks. Today, new, environmentally friendly and efficient fire extinguishing agents have emerged in an endless stream. In contrast, 1211 fire extinguishing agent has not met the needs of the times for green and safe fire protection, so it is gradually withdrawing from the historical stage.
1211 What are the storage conditions for Extinguishants?
1211 fire extinguishing agent is a kind of halogenated alkane fire extinguishing agent, and its storage conditions are quite important.
First, it should be stored in a cool place. It is hot in the summer and the sun is exposed to intense sunlight. If it is placed in the sun, the temperature will be too high, or the internal pressure of 1211 fire extinguishing agent will suddenly increase, and the container may break and endanger the safety of the surrounding area.
Second, it should be placed in a dry place. If the environment is humid, the outer wall of the container is prone to rust. After a long time of corrosion, the strength of the container will be greatly reduced, and eventually it will leak, making the fire extinguishing agent ineffective.
Third, a well-ventilated place should be placed. If the ventilation is not good, once there is a slight leakage of fire extinguishing agent, the gas will accumulate and not disperse. If people are in the middle, excessive inhalation will damage health, and the halogenated alkane will encounter an open flame or hot topic, or there is a risk of decomposition, resulting in harmful gases.
Fourth, where it is stored, it should be avoided near fire and heat sources. The fire source is hot and the heat source is drying, which can cause the 1211 fire extinguishing agent to heat up and cause danger. This is like dry wood near fire, which is ready to explode at the touch.
Fifth, the container must be well sealed. If the seal is not good, the fire extinguishing agent may escape, the efficacy is greatly reduced, and external water vapor and impurities take advantage of it, or chemically react with the fire extinguishing agent, causing it to deteriorate.
Also, the storage temperature is also limited, preferably between -20 ° C and 55 ° C. If the temperature is too low, the extinguishing agent or solidification will affect the injection; if the temperature is too high, the pressure will rise sharply and the container will be difficult to bear. And the storage area should be stable and safe, so as not to be hit by external forces and cause damage to the container. In this way, the 1211 fire extinguishing agent can be stored safely and effectively.
