Negative catalyst extinguishant and production thereof

Abstract

A negative catalyst fire-extinguishing chemical especially for automatic fire extinguishing system is prepared through proportionally mixing water, borax and water glass, stirring, adding tourmalinite and monazite, stirring to become liquid colloid, adding salt, ammonium dicarbonate and diammonium hydrogen phosphate, stirring while heating to 30-60 deg.C, stirring until it cooled to 20-40 deg.C, adding urea and ammonium sulfate, and stirring. It can automatically cut off fire source.

Description

technical field [0001] The invention belongs to fire-fighting and fire-extinguishing materials, in particular to a negative catalyst fire-extinguishing agent and a manufacturing method. Background technique [0002] Fire has become a worldwide public enemy, and it kills tens of thousands of lives every year in the world, and it brings a very huge disaster to human life and property. It is difficult for human beings to put an end to fires, but reducing fire hazards is an essential means. The fire extinguishing technology that mankind has been looking forward to for a long time, the existing traditional fire extinguishing methods generally have many forms: such as dilution fire extinguishing, (also known as suffocation fire extinguishing), the main principle is to locally produce non-toxic gases (such as carbon dioxide or foam) ), to dilute the oxygen concentration, or block the contact of the combustibles with oxygen, so as to achieve the ...

AI Technical Summary

Problems solved by technology

Defects: complex operation, low fire extinguishing efficiency, uncontrollable fire, poor continuous fire extinguishing performance, easy to cause personal injury, requires professional training knowledge, not suitable for all groups of personnel, and will cause indirect property loss, and will cause environmental damage Pollution, volatile burning fire powerless, etc.

Disadvantages: Professionals (professional fire hydrants or fire trucks) are required to extinguish the fire. From the discovery of the fire to the alarm, the response delay time cannot be controlled. It is also restricted by distance and traffic, and restricted by local water sources. The fire extinguishing efficiency is low and the oil cannot be controlled. Class fire, easy to cause personal injury, requires professional training knowledge, not suitable for all groups of personnel to use, and will cause indirect property loss, will cause the phenomenon of reburning, powerless to volatile fires, often the fire will be extinguished The things are burnt out, and the rescue of personnel is difficult due to the long time for fire extinguishing, etc.

Each fire extinguishing agent has a certain degree of defects, the fire extinguishing efficiency is not high, the price is relatively expensive, the device is bulky and occupies a large space, pollutes the environment, is harmful to health, and each fire extinguishing agent also has its own place and scope of application
