Problems solved by technology

Ammonium phosphate occupies the absolute position of dry powder fire extinguishing agent because of its excellent fire extinguishing performance and environmental protection performance, but ammonium phosphate is very hygroscopic and prone to agglomeration, so it cannot maintain a loose powder state for a long time
At the same time, due to the poor movement performance of the powder, it is difficult to achieve rapid and uniform mixing of gas and powder
The existing technology of adding crushing aids, hydrophobic components and functional fillers in large quantities can improve the crushing fineness and meet the performance requirements to a certain extent, but it greatly reduces the fire extinguishing efficiency

Embodiment Construction

[0030] An ammonium phosphate high-efficiency superfine dry powder fire extinguishing agent and a production method thereof.

[0031] 1. Composed of the following components by weight (based on 100 kg):

[0032]

[0033] 2. Production process:

[0034] (1) monoammonium phosphate passes through 80 mesh sieves through Renault mill coarse powder;

[0035] (2) Put the monoammonium phosphate of the coarse powder together with mica, white clay, white carbon black and additives into the ultrafine pulverizer and pulverize until the average particle size is ≤5 μm;

[0036] (3) The above-mentioned fine powder material is silicified using silicone oil in a coating machine:

[0037] a. After the fine powder material is added to the coating machine, the temperature rises to 60°C and sprays silicone oil at a speed of 150r / min;

[0038] b. Add hydrophobic white carbon black 15 minutes after spraying silicone oil;

[0039] c. Continue silicification for 15 minutes and raise the temperat...

Abstract

The invention adopts the ammonium phosphate high-efficiency superfine dry powder fire extinguishing agent produced by sub-nanometer ultrafine grinding, synergistic effect and surface modification technology, which realizes the fire extinguishing efficiency of more than 10 times that of ordinary dry powder fire extinguishing agent, and can be widely used in extinguishing A and B , Class C, and E fires, with excellent submerged fire extinguishing efficiency and smoke suppression function, and long storage period, environmentally friendly and non-toxic, many parameters, especially fire extinguishing efficiency, are far superior to the requirements of the GA578‑2005 "Ultrafine Dry Powder Fire Extinguishing Agent" standard. It can be filled with various fire extinguishing devices and pipe network fire extinguishing systems commonly used at present, and can even be used as a cold aerosol. The invention has simple production process, less equipment investment and low production cost, and is suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of superfine dry powder fire extinguishing agent processing, in particular to an ammonium phosphate high-efficiency superfine dry powder fire extinguisher and a production method thereof. Background technique [0002] Combustion is a severe chain oxidation reaction carried out by the continuous transmission of active free radicals. The active extinguishing components in the dry powder fire extinguishing agent capture and terminate the free radicals generated by the combustion reaction, reducing the rate of the combustion reaction. When the concentration of the dry powder fire extinguishing agent in the flame is high enough and the contact area with the flame is large enough, the rate of free radical termination is greater than that of the combustion reaction. The rate at which the reaction is formed, the chain combustion reaction is terminated, and the flame is extinguished. Therefore, the content and particle size o...
