The ideal substitute of agent.
At present mobile fire extinguishing device can be divided into：1st, various portable, Backpack fire-extinguishers, to the first of every profession and trade
Phase fire disasters protection is puted out a fire to save life and property；Advantage is convenient rapid, and defect is that fire-fighting dose is little, is only applicable to small range fire extinguishing.2nd, professional fire-fighting
The various fire fighting trucks of army, mainly tackle some large-scale fire attacks.Advantage applies to large area fire, and defect is mobile
It is inconvenient.3rd, drawing, cart type, vehicular fire-extinguishing device, such device has filled up portable, Backpack fire-extinguisher and specialty disappears
Blank between the various fire fighting trucks of anti-army, but such device uses dry powder, water and foam as firing-fighting medium, for going out
Fiery agent has the place of particular/special requirement, such as precision instrument and equipment, book and file shop, Engine Room, precious historical relic's protection place etc.,
The use of existing mobile extinguishing device is restricted.
On the other hand, pulling a cart used in current mobile extinguishing device is mostly two-wheel, can only be satisfied with plane
On use, be not convenient to use stair and with slope uneven ground etc. complexity landform, limit its use range.
The content of the invention
In place of in view of the shortcomings of the prior art, the formula perfluoro-ethyl isopropyl the purpose of the present invention is to propose to one kind is pulled a cart
Ketone fire gun.
Second object of the present invention be propose described in pull a cart the application process of formula perfluorethyl isopropyl ketone fire gun.
The technical scheme for realizing the object of the invention is：
