I have a question if you will kindly help me out.
i am trying to make fire fighting powder which is to be use on B and C class fires. I have tried many things but as compare to pre-made chemicals(available in market) the results are not 100% by means of flow/volume/water resistance and cost efficient.
The main physical property of fire extinguisher powder is: the flow show be great and by mixing in water it should not dissolve in water.
Things i have tried.
potassium gluconate 88.75 parts
barium sulfate 10.00 parts
silicone oil 0.50 parts
aerosil R 972 (Degussa) 0.75 parts
ammonium sulfate 39.0 parts
barium sulfate 10.0 parts
potassium gluconate 10.5 parts
silicone oil 0.3 parts
aerosil 1.2 parts
sodium chloride 55 to 65 percent
magnesium chloride 30 to 45 percent
calcium chloride 0 to 8 percent
Barrium sulfate 58
Potassium bicarbonate 20
sodium bicarbonate 20
str 2
etc
Keeping in mind that when we pour BC Extinguisher powder and stir, it does not get mixed. I have talked with few local manufacturers they said that they are using two - three chemicals but it is confidential to tell the names.

Re: BC Fire Extinguisher Powder
I dont know what you realy want. A fire extinguisher has to work. They have to bought from companies who are responsible for correct work. Also after 2 years they have to exchanged and tested. Your home brew mixtures without any knowledge are to dangerous of male function.
And if companies don't tell the secrets, here in the forum we will also not do.

I am not trying to sell it, its for study and yearly task that we have to complete. as a matter of fact i am successful 90% but by means of hydrophobic, flow and volume mine are not the same. On internet there are thousand of patents but they are missing some parts.ChenBeier wrote: ↑Fri Jan 28, 2022 9:50 am I dont know what you realy want. A fire extinguisher has to work.

Re: BC Fire Extinguisher Powder
