Introduction of " perfluoroethyl perfluoroisopropyl ketone " extinguishing agent

The damage of ODS to the ozone layer, it is causing serious harm to the environment of human and other organisms. As a result, the Montreal protocol on the ozone layer was developed in 1987 and decided to phase out the Halon extinguishing agent all over the world. At present, the existing Halon replacement agents, which are being developed and used at home and abroad, mainly have HFCS, perfluorocarbons, inert gases, aerosols and water mist. They each have their advantages and disadvantages. Especially for hydrogen fluoride hydrocarbon fire extinguishing agent, although it has solved the problem of the destruction of the ozone layer, however, due to its high ozeme depletion potential and long residence time atmospheric greenhouse effect, now Britain and the United States have included it in the list of controlled programs, and therefore it should not be considered as a long-term alternatives.

Application

Fire extinguishing agent can be used in portable fire extinguisher and fire extinguishing system of the whole area or regions, NY5112 can be widely used in the following areas:

DP center        Electronic control center       precision instrument

Archive           Library                        Museum

naval ships        ocean-going vessel          commercial aviation

subway station     Mall                    assembly occupancies

Besides that，NY5112 can be used as a protection gas during melting of magnesium alloy or other light metal alloy.

Product Advantage

 ·Environmental：It doesn't cause damage to the ozone layer, the GWP is less than 1, the ALT is 0.014 year. The environmental performance of the product meets the international requirements of the most stringent environmental regulations.

·Low Fire extinguishing concentration：The extinguishing concentration of NY5112 is much lower than its NOAEL, which leads to more safety and low toxicity.

·Good insulation：No damage to sophisticated equipment.

·No residue: There will be no damage to paper documents, treasures and antiques.

·Convenient Transportation and filling： NY5112 is a liquid at room temperature, so the storage and transportation are convenient.

extinguishing concentration and safety

NY5112 has excellent fire extinguishing performance. The concentration of fire extinguishing in class A and B is 3.5%、4.5%，which are the closest to the performance of halon extinguishing agent .It can extinguish A, B, C fires, non-conductive, immediately gasification after the injection, leaving no residue.

Table 3 The comparison of the extinguishing concentration and safety data of perfluoroethyl perfluoroisopropyl ketone with halon and some halon substitutes

The safety of the NY5112 is greater than 72 to 122% of the fire extinguishing concentration and the safety margin is larger; The safe value of halon 1301 is very close to its fire extinguishing, but with no safe margin. Besides that, the GWP and ODP values are high and have a serious impact on the atmosphere and have been banned globally from production and use. The safe value of HFC-227ea is higher than its fire extinguishing, so the safe margin is small. Not only that, but also the greenhouse effect is still high and has a detrimental effect on the climate; CO2 extinguishing agent has a choking effect on people in the concentration of fire extinguishing. NY5112 is an environmental protection agent that is compatible with the safety and environment requirements and is better suited for fire protection in some places while ensuring the efficiency of fire protection.
