Heptafluoropropane(FM200) extinguishing agent profile:
Heptafluoropropane at room temperature is a colorless, odorless, non-conductive,
may be stored in the low-pressure liquefied gas fire extinguishing agent, a density of
about 6 times the air density (the physical properties shown in Table 1) of the formula
CF3CHFCF3, trade name HFC-227ea, foreign called FM-200 (its technical
performance are shown in Table 2), the extinguishing agent suitable for total flooding
fire extinguishing system. When the activity of free radicals generated by the
decomposition extinguishing agent is sprayed to the protection zone, flame or fire
extinguishing agent contact hot surfaces, the radical chain reaction seize combustion
generated active substances, destruction combustion process chain transfer, and
ultimately achieve the purpose of extinguishing the ways a chemical fire, cooled,
diluted or cut off the air and other physical effect is minimal. Because of its high
performance fire, the equipment clean, does not destroy the ozone layer, etc., is the
alternative to Halon fire extinguishing agent of choice for products, now available in
many countries and regions of the world has been widely used. Ministry of Public
Security has also been recommended as an alternative to the use of Halon widely used
in electricity, water conservancy, metallurgy, petrochemical, telecommunications,
industrial and mining enterprises, banking, civil aviation and other industries of
various important places of protection in our country, such as a computer room,
communications room, precision instrument rooms, physics and chemistry
laboratories, generator room, changed appliances, books, libraries, databases, archives,treasury, oil platforms, hydraulic oil tanks of flammable liquids and other combustibleroom and easy to produce electrical fire hazard areas.
