Problems solved by technology

[0004] At present, most of the dry powder fire extinguishing agents on the market have great differences in performance. Due to poor water repellency and high moisture absorption rate, the product is agglomerated and the shelf life is shortened, resulting in low fire extinguishing efficiency. Therefore, it is necessary to strengthen research on this aspect and further improve it. defect

Abstract

The invention provides a novel ABC dry powder extinguishing agent. The novel ABC dry powder extinguishing agent is mainly prepared from, by mass, 14-22 parts of caustic sludge, 36-48 parts of potassium sulphate, 25-35 parts of sodium oxalate, 8-14 parts of limestone, 5-10 parts of magnesium carbonate powder, 6-9 parts of methyl silicone oil, 7-13 parts of ammonium sulfate, 4-8 parts of zinc borate, 2-5 parts of stannic oxide, 3-6 parts of graphite powder and 1-5 parts of coal ash. The preparation method of the obtained product is simple; the fire extinguishing performance is excellent; the higher electrical insulating property, water repellency and anti-caking performance are achieved; industrial waste materials are utilized reasonably, so that the production cost is reduced; and the market prospect is good.

Description

technical field [0001] The invention relates to the field of fire extinguishing agents, in particular to a novel ABC dry powder fire extinguishing agent and a preparation method. Background technique [0002] Dry powder fire extinguishing agent is made of fire extinguishing base material (such as baking soda, ammonium carbonate, ammonium phosphate, etc.) Made of fine particles, using carbon dioxide as a jet power. The sprayed powder has a dense concentration and fine particles. Covering the solid combustion material, it can form an isolation layer that hinders combustion, and at the same time precipitates non-combustible gas, which reduces the oxygen concentration in the air and extinguishes the flame. Dry powder fire extinguishing agent can be filled in various types of portable and fixed dry powder fire extinguishing devices. It can be used in combination with fluoroprotein foam fire extinguishing agent and aqueous film-forming foam fire extinguishing agent to extinguish ...
