Abstract

The invention discloses an ABC ultra-fine dry powder extinguishing agent. The ABC ultra-fine dry powder extinguishing agent comprises the raw materials of, by weight, 15-25 parts of ammonium dihydrogen phosphate, 5-9 parts of potassium sulphate, 5-10 parts of alum, 2-5 parts of magnesium carbonate, 4-8 parts of ammonium sulfate, 2-4 parts of raw gypsum, 10-12 parts of hydrophobic white carbon black, 0.5-1 part of raw gypsum, 2-4 parts of bentonite, 1-2 parts of methylsilicone oil and 2-5 parts of pentaerythritol. The ABC ultra-fine dry powder extinguishing agent provided by the invention is superior in extinguishing performance and high in efficiency, has the water repellency, is good in fluidity and superior in anticaking capacity, can be stored for long time and has a good market prospect, and by means of the ABC ultra-fine dry powder extinguishing agent, the material cost is greatly lowered, and the diminishing phosphate rock resources are further saved.

Description

technical field [0001] The invention relates to the technical field of dry powder fire extinguishing agents, in particular to an ABC superfine dry powder fire extinguishing agent. Background technique [0002] With the elimination of halon fire extinguishing agent, various scientific research institutes, enterprises, and colleges and universities engaged in fire technology research and application of new fire extinguishing equipment have continuously developed new fire extinguishing agents and equipment to replace halon fire extinguishing agents and equipment, ABC dry powder fire extinguishing agent Since it was popularized and applied in my country in the 1980s, it has developed rapidly and its production capacity has continued to expand. [0003] The traditional ABC dry powder fire extinguishing agent uses ammonium dihydrogen phosphate as the main fire extinguishing substance. When the solid material catches fire, the combustible solid will continuously gasify into combusti...
