Usage of Heptafluoropropane
Heptafluoropropane(HFC-227ea)is a kind of chemical way and clean gas extingushing agent,its colorless, flavourless, innocuous, nonconducting. And will not pollute the object to be guarded.In particular will not destory atmospheric ozone layer,(0DP value is zero)accord with the environmental requirement,it is halon extingguishing agent perfect surrenal at present stage.This kinds of fire extinguishingagent have thecharacteristic of high efficiency in outfire,high speed,have no secondary pollution,can out fire like this kinds of area:
(1)safeguard include valuables,priceless treasure,or the firm important date and soft hardwar device and etc....;
(2)The device where have no automatic sprinkler system or the device will dmage by water;
(3)The area where people regularity live in;
(4)The area where it's hard to clean after eject medicament;
(5)Medicament steel cylinder space is limited,a small amount evtinguishing medium can put out the fire;
(6)The object to be guarded is electric equipment,must use the non-conductive extinguishing medium.
Packing:
Filled in cylinders, each 1000kg net. Its category of dangerous goods is 2.2, and its packing category is second grade.
