Metal zirconium fire extinguishing agent and preparation and use methods thereof

Abstract

The invention belongs to the field of fire extinguishing agents and particularly provides a metal zirconium fire extinguishing agent which comprises the following components in percentage by mass: 30%-32% of modified quartz sand; 32-35% of modified sodium chloride, 20%-23% of ammonium polyphosphate, 2%-3% of magnesium stearate, 3%-4% of hydrophobic silicon dioxide, 1%-2% of vermiculite powder and1% of mica powder. In the fire extinguishing process, chemical fire extinguishing and physical fire extinguishing can be combined, a reaction chain of metal zirconium combustion is cut off, and the good effects of cooling, after-combustion resistance and dust explosion inhibition are achieved. The invention further provides a preparation and use method of the zirconium metal fire extinguishing agent. The preparation method is simple, low in cost, easy to store and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing agents, in particular to a fire extinguishing agent for metallic zirconium fires and a preparation method thereof. Background technique [0002] Zirconium is widely used in chemical equipment manufacturing because of its excellent corrosion resistance, especially reactors, heat exchangers, pumps, valves, pipes, etc. in acetic acid, pesticides, plastics and other industries. In recent years, the civil zirconium material market has benefited from the rapid development of my country's chemical industry, showing a trend of increasing demand year by year. With the increasing demand for metal zirconium, it has led to frequent occurrence of metal zirconium fires. Metal zirconium fires have high combustion temperature and strong thermal radiation; it is difficult to fight fires, and it reacts with oxygen, nitrogen, etc., and can react with ordinary dry powder fire extinguishing agents, foam fir...

AI Technical Summary

Problems solved by technology

Metal zirconium fires have high combustion temperature and strong thermal radiation; it is difficult to fight fires, and it reacts with oxygen, nitrogen, etc., and can react with ordinary dry powder fire extinguishing agents, foam fire extinguishing agents, and gas fire extinguishing agents. It may also cause the fire to spread and explode; it is difficult to fight the fire, and it is very easy to generate dust explosion, and the shock wave and high-temperature gas generated by the explosion can easily cause casualties

[0003] The fire extinguishing agents for metal fires are all developed according to the properties of metal fires. The formulas of fire extinguishing agents for different metal fires are different. The fire extinguishing agent for metal sodium is used to fight fires caused by triethylaluminum, metal magnesium, and metal zirconium. The effect is not good; the fire extinguishing agent for extinguishing triethylaluminum is not effective in extinguishing the fires of metal sodium, metal magnesium, and metal zirconium. The fire has a good effect, but there is no research and development for metal zirconium, and none of them can quickly and effectively extinguish the metal zirconium fire
