Hot-aerosol fire-extinguishing agent

Abstract

The invention relates to a hot-aerosol fire-extinguishing agent. The hot-aerosol fire-extinguishing agent comprises the following raw materials in percentage by weight: 10-30% of potassium nitrate, 10-30% of zinc nitrate, 10-30% of magnesium nitrate, 10-30% of guanidine nitrate, 6-10% of manganese dioxide, 0.2-0.8% of bamboo charcoal, 0.2-0.8% of azodicarbonamide, 0.5-1% of metallic magnesium, 0.2-0.8% of adhesive and 0.2-0.8% of thermite. The formula of the materials is improved, the ideal state of efficient fire extinguishment of potassium salt in an oxidizing agent is exerted, and the reaction time of the materials is adjusted, thus the concentration of the solid particles of the potassium salt after reaction in the oxidizing agent in a hot-aerosol fire-extinguishing gas is lowered to achieve no corrosion. The hot-aerosol fire-extinguishing agent is suitable for fire extinguishment for a generator room with a high accuracy requirement.

Description

technical field

[0001] The invention belongs to the technical field of fire protection, and in particular relates to a hot aerosol fire extinguishing agent. Background technique

[0002] Aerosol fire extinguishing agents can be divided into hot aerosols and cold aerosols. At present, the aerosol fire extinguishing devices used in domestic projects all belong to the hot type, and the cold aerosol fire extinguishing technology is still in the development stage. Aerosol fire extinguishing devices are usually only suitable for smaller protection areas, because the pressure of aerosol fire extinguishing gas ejected from the device is very small, about 0.02MPa, and the spray distance is 1-2m. The specific gravity of aerosol fire extinguishing gas is very small, slightly The air is heavier, it floats to the top of the protected area first, and then gradually settles at the bottom of the protected area. Since the protected equipment is placed on the ground, the fire extinguishing...
