Embodiment 1
[0051] Example 1 A new type of ultrafine dry powder fire extinguishing agent is prepared from the following raw materials (25 kg per part): 19 parts of alkali slag, 32 parts of ammonium dihydrogen phosphate, 22 parts of sodium bicarbonate, 15 parts of potassium iodate, and sodium oxalate 14 parts, magnesium carbonate 9 parts, silicone oil 12 parts, ammonium phosphate 28 parts, chlorinated rubber 12 parts, zinc borate 15 parts, glass fiber 8 parts, fly ash 6 parts.
[0052] The preparation method of novel superfine dry powder fire extinguishing agent, the steps are as follows:
[0053] (1) Crushing of raw materials
[0054] (1) Conventionally crush sodium bicarbonate and glass fiber, mix them evenly, pass through a 30-mesh sieve, and place them in a jet mill for 25 minutes. When the current is stable, continue to add alkali slag, magnesium carbonate and chlorinated rubber. Crush for 35 minutes;
[0055] (2) Put the ammonium dihydrogen phosphate and ammonium phosphate in the c...
