A type fire extinguishing agent, and its preparation method and application method

Abstract

The invention discloses an A type fire extinguishing agent which comprises, by weight, 0.3% to 0.8% of polyacrylamide and 0.18% to 0.30% of xanthan gum, with the balance being water. The invention also discloses a preparation method and an application method of the fire extinguishing agent. The fire extinguishing agent composed of the two above-mentioned raw materials in the invention has good fire extinguishing performance; gel liquid of the agent can rapidly isolate air, thereby achieving an effect of flame retardation.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a type A fire extinguishing agent, its preparation method and use method. Background technique [0002] Fire extinguishing agents generally refer to those substances that can effectively destroy the combustion conditions in the combustion zone, so as to inhibit or stop the combustion. There are many types of fire extinguishing agents, and the commonly used fire extinguishing agents include water, foam, carbon dioxide, dry powder, haloalkane fire extinguishing agents, etc. [0003] The classification of fire extinguishing agents can also be divided into the following four categories for the following fire types: [0004] Class A fire: refers to the fire of burning solid combustibles containing carbon, such as wood, cotton, wool, hemp, paper, etc.; [0005] Class B fires: fires involving the burning of nail, B, and C liquids, such as gasoline, kerosene, diesel, ...
