Problems solved by technology

However, when extinguishing a flammable liquid fire, due to the strong lipophilicity of the hydrophobic film on the surface of the dry powder particles sprayed onto the liquid surface, it will sink quickly, and the small remaining flames will ignite the entire liquid surface. The most challenging re-ignition problem currently faced by dry powder fire extinguishing technology needs to be solved urgently

Abstract

The invention relates to an extinguishing agent, and particularly discloses an efficient BC dry powder extinguishing agent. The efficient BC dry powder extinguishing agent comprises raw materials of,by weight, 50-70 parts of potassium bicarbonate, 20-28 parts of barium chloride, 4-10 parts of tributyl phosphate, 3-8 parts of anti-reburning agents, 1-4.5 parts of silica powder, 1.2-3.4 parts of chromium sulfate, 2.3-5.6 parts of silica gel, 1.3-2.2 parts of magnesium stearate, 0.4-0.9 part of pentaerythritol, and 0.2-0.6 part of methylcyclopentadienyl manganese tricarbonyl. The efficient BC dry powder extinguishing agent has excellent anti-reburning performance.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to a high-efficiency BC dry powder fire extinguishing agent. Background technique [0002] Dry powder fire extinguishing agent is one of the more commonly used fire extinguishing agents. According to the type of fire fighting, dry powder fire extinguishing agents are usually divided into ABC dry powder fire extinguishing agents based on ammonium phosphate, suitable for general fires, sodium bicarbonate (potassium bicarbonate) as base materials, used for flammable liquids or flammable BC dry powder fire extinguishing agent for gas fires, and dry powder fire extinguishing agent for metal fires based on sodium chloride, graphite, perlite and other materials. However, when extinguishing a flammable liquid fire, due to the strong lipophilicity of the hydrophobic film on the surface of the dry powder particles sprayed onto the liquid surface, it will sink quickly, and the small remaining fla...
