Problems solved by technology

Existing hot aerosol fire extinguishing agent exists the potassium nitrate in the oxidizing agent, and the product K after its reaction 2 O is very easy to absorb moisture in the air and deliquesce, which may corrode the equipment and documents in the protected area. There is an improvement in the proportion of oxidants in the existing market. The corrosiveness of the concentration in the gas is still slightly higher, and it still cannot meet the required requirements for equipment with high precision requirements, such as power transformation and distribution rooms and generator rooms

Embodiment 1

[0010] Embodiment 1: a kind of hot aerosol fire extinguishing agent, the raw material according to percentage by weight comprises: potassium nitrate 25%, zinc nitrate 21%, magnesium nitrate 21%, guanidine nitrate 22%, manganese dioxide 8%, bamboo charcoal 0.5%, azo Diformamide 0.5%, Metal Magnesium 1%, Binder 0.5%, Thermite 0.5%.

[0011] Further, the binder is corn starch.

[0012] Still further, the thermite is aluminum.

[0013] Among the materials, potassium nitrate, zinc nitrate, magnesium nitrate, and guanidine nitrate are used as oxidizing agents, manganese dioxide is used as a catalyst, and bamboo charcoal and azodicarbonamide are used as reducing agents. Mix potassium nitrate, zinc nitrate, magnesium nitrate, guanidine nitrate, manganese dioxide, bamboo charcoal, and azodicarbonamide according to the above percentages, then put them into a ball mill, and grind them evenly; then add metal magnesium, binder, aluminum Hot agent, and then grind evenly. Take out the mix...

Embodiment 2

[0014] Embodiment 2: a kind of hot aerosol fire extinguishing agent, the raw material according to weight percentage comprises: potassium nitrate 16%, zinc nitrate 30%, magnesium nitrate 15%, guanidine nitrate 30%, manganese dioxide 6.5%, bamboo charcoal 0.2%, azo Diformamide 0.8%, Metal Magnesium 0.5%, Binder 0.8%, Thermite 0.2%.

[0015] Further, the binder is corn starch.

[0016] Still further, the thermite is aluminum.

[0017] In this example, after repeated research and experimentation on the components of the oxidant, the formula of the material has been improved, which not only brings into play the ideal state of efficient fire extinguishing by the potassium salt in the oxidant, but also adjusts the reaction time of the material so that the reaction time of the potassium salt in the oxidant is The concentration of solid particles in the hot aerosol extinguishing gas is reduced to non-corrosive. It is suitable for fire extinguishing in substation distribution rooms a...

Embodiment 3

[0018] Embodiment 3: a kind of hot aerosol fire extinguishing agent, comprises according to the raw material of weight percent: potassium nitrate 15%, zinc nitrate 22%, magnesium nitrate 25%, guanidine nitrate 25%, manganese dioxide 10%, bamboo charcoal 0.5%, azo Diformamide 0.5%, Metal Magnesium 1%, Binder 0.5%, Thermite 0.5%.

[0019] Further, the binder is corn starch.

[0020] Still further, the thermite is aluminum.

[0021] In this example, after repeated research and experimentation on the components of the oxidant, the formula of the material has been improved, which not only brings into play the ideal state of efficient fire extinguishing by the potassium salt in the oxidant, but also adjusts the reaction time of the material so that the reaction time of the potassium salt in the oxidant is The concentration of solid particles in the hot aerosol extinguishing gas is reduced to non-corrosive.

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...
