What's the difference between a dry fire extinguisher and a 2 carbon dioxide extinguisher?

Answer:

Carbon dioxide fire extinguisher mainly depends on the action of carbon dioxide suffocation and partial cooling. Extinguish fire from books, archives, precious equipment, precision instruments, electrical equipment and oils under 600 volts. Use well in the dust proof area.
Two, powder powder falls on the surface of combustible, chemical reaction, and in the high temperature under the action of forming a layer of glass like coating, so as to isolate oxygen, and then smothering fire. Used for fighting flammable oil, organic solvents and other flammable liquids, flammable gases and electrical equipment of the initial fire. Not applicable in dustproof area.
A fire extinguisher is by the inorganic salt powder volatile decomposition products, chemical inhibition and negative catalysis and fuel combustion in the process of free radicals or reactive groups, the chain reaction of combustion and extinguishing interrupt;
