And sodium bicarbonate solution, two kinds of solution are not in contact with each other, and any chemical reaction does not occur.When needing foam annihilator, fire extinguishing
Device stands upside down, and two kinds of solution mix, and will generate a large amount of carbon dioxide gas.
Carbon dioxide extinguisher principle is: storing liquid carbon dioxide in fire extinguisher bottle body, when work, when pressure cylinder valve
When handle.Internal carbon dioxide extinguishing agent is just sprayed by siphon pipe by cylinder valve to spray canister, keeps the concentration of combustion zone oxygen rapid
Decline, when carbon dioxide reaches enough concentration, flame can suffocate and extinguish, simultaneously because liquid carbon dioxide can gasify rapidly,
A large amount of heat is absorbed in a short period of time, therefore plays certain cooling effect to comburant, it helps fire extinguishing.Cart
Formula carbon dioxide extinguisher is mainly partially being formed by bottle body, device head assembly, jet pipe assembly, frame assembly etc. are several, and built-in goes out
Fiery agent is liquid carbon dioxide fire-fighting agent.
But the starter of carbon dioxide extinguisher there is also some problems at present.
