Description

technical field

[0001] The invention relates to a production process of a fire extinguishing agent, in particular to a production process of a dry powder fire extinguishing agent. Background technique

[0002] Dry powder is a dry solid fine powder with a water content of no more than 0.1-0.2%, good fluidity, a particle size mostly below 200 mesh, and a high specific surface area (2000-3500 cm2 / g). Dry powder fire extinguishing agents are usually powered by high-pressure carbon dioxide gas (or nitrogen) and are used to extinguish flammable, combustible liquids, liquefied petroleum gas and natural gas and other flammable gases, as well as initial fires of electrical equipment.

[0003] Sodium bicarbonate or potassium bicarbonate is often used as the base material for dry powder fire extinguishing agents, and an appropriate amount of moisture-proof agent, fluidity promoter and caking preventive agent (such as talcum powder, mica powder, graphite powder, magnesium stearate, acti...
