Embodiment 1

[0036] Observe the time and phenomenon of the fire extinguishing agent being ignited by the surrounding fire after it is attached to the combustible material, so as to infer its ability to prevent the high temperature ignition of the surrounding fire after it is sprayed on the burning material.

[0037] Use the recipe for

[0038] Potassium bromide: 5%; (mass percentage)

[0039] Tween-80: 0.1%; (mass percentage)

[0040] Sodium carboxymethyl cellulose: 2%; (mass percentage)

[0041] Sodium silicate: 2%; (mass percentage)

[0042] Sodium polyacrylate: 1%; (mass percentage)

[0043] Disodium edetate: 0.2% (mass percentage)

[0044] The balance is water.

[0045] Using an alcohol flame as the ignition source, the flame can coat the material for combustion. Soak each material in water and in the fire extinguishing agent of the present invention (the above formula) for 1 second, take it out and let it air in the air for 1 minute. Put it in the flame at an angle of 75-80° (t...

Embodiment 2

[0052] Fire extinguishing performance and reflammability.

[0053] The formula used is:

[0054] Potassium bromide: 5%; (mass percentage)

[0055] Tween-80: 0.1%; (mass percentage)

[0056] Sodium carboxymethyl cellulose: 1%; (mass percentage)

[0057] Sodium silicate: 2%; (mass percentage)

[0058] Sodium polyacrylate: 1%; (mass percentage)

[0059] Disodium edetate: 0.2% (mass percentage)

[0060] The balance is water.

[0061] Set a vertical 20cm×50cm×0.5cm pine plank, use a nozzle with the same specification DV95=1000μm, and use 0.8MPa air as the driving pressure to drive water and fire extinguishing agent respectively. Orient the nozzle to the center of the board.

[0062] Set a gasoline ignition source of the same specification under the plank. The specifications of the gasoline oil pan are 8cm×8cm×4cm. After 1 minute of ignition, spray water and fire extinguishing agent respectively.

[0063] Water 15s to extinguish the plank fire. After the water is sprayed ...

Abstract

The invention relates to an adhering type water-based fire extinguishing agent for a vertical surface solid fire. A formula of the fire extinguishing agent comprises 3-10% of one or more than two of potassium acetate, potassium bromide, potassium oxalate or potassium bicarbonate, 0.1-0.5% of a non-ionic surface active agent, 1-5% of sodium carboxymethylcellulose, 1-5% of sodium silicate, 0.5-2% ofsodium polyacrylate, 0.1-0.3% of a calcium-magnesium ion complexing agent and the balance water. The fire extinguishing agent will greatly improves the fire extinguishing efficiency of the vertical surface solid fire.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to an adhesive water-based fire extinguishing agent for vertical solid fires. Background technique [0002] Due to the air heating effect caused by the flame, its propagation speed in the vertical direction is much faster than that in the horizontal direction. Simultaneously, for vertical surface solid fire, commonly used fire extinguishing agent is difficult to keep on it. Take water extinguishing curtain fire as an example. When a vertical curtain breaks out in a fire, when water is used as an extinguishing agent, a large amount of water will not remain on the curtain, making it difficult to extinguish the fire. Another example is that when a fire breaks out with water to extinguish the thermal insulation material of the building's exterior wall, it will face the problem of a large amount of water being lost along the wall in vain. The problem that brings like this is: (1) fire ext...
