Problems solved by technology

[0012] At present, the ABC dry powder fire extinguishing agent commonly produced in China contains about 50% of monoammonium phosphate and about 25% of ammonium sulfate, and the rest are auxiliary materials. On the other hand, from a theoretical analysis, the higher the proportion of ABC dry powder fire extinguishing agent powder particle size less than 0.04mm, the higher the fire extinguishing efficiency, but the current ABC dry powder fire extinguishing agent manufacturers regard the powder particle size less than 0.04mm The proportion is controlled within 50%, and its fire extinguishing efficiency is low, which is the main defect of the current ABC dry powder fire extinguishing agent

Abstract

The invention provides a high-efficiency ABC dry powder extinguishing agent with the content of main components being larger than 90%. The high-efficiency ABC dry powder extinguishing agent is characterized in that the components comprise monoammonium phosphate and ammonium sulfate, wherein the mass fraction of the monoammonium phosphate is larger than 75%, and the sum of the mass fractions of the monoammonium phosphate and the ammonium sulfate is larger than 90%. The powder granularity is reasonable in distribution, and the content of the monoammonium phosphate in a chassis is larger than 75%. The high-efficiency ABC dry powder extinguishing agent has the advantages of being high in content of main components, good in extinguishing effect, simple in production process and the like, and has high market potential.

Description

technical field [0001] The invention belongs to the field of fire extinguishing agents, in particular to a high-efficiency ABC dry powder fire extinguishing composition. technical background [0002] Dry powder fire extinguishing agent is composed of one or more fine inorganic powders with fire extinguishing ability, and its fire extinguishing mechanism is as follows: [0003] (1) Chemical inhibition: The combustion process is a chain reaction process. OH and H free radicals are the key free radicals to maintain the combustion chain reaction. They have high energy and are very active, but their lifespan is very short. Initiate the next reaction to generate more free radicals, so that the combustion process can continue and continue to expand. The fire extinguishing component of the dry powder fire extinguishing agent is a burning inactive substance. When the dry powder fire extinguishing agent is added to the combustion zone and mixed with the flame, when the dry powder pow...
