Ultrafine dry powder belongs to the category of gas. It uses a solid-gas conversion form to achieve spraying. There is no pressure at room temperature and normal state. More than 90% of the ultrafine dry powder has a particle size of less than 20 microns and reaches the sub-nanometer level. The main ingredient is ammonium phosphate, which is one of the most traditional and common fire extinguishing agents. It is non-corrosive to precision instruments, human bodies, and paper. It can be charged with fire extinguishing time ≤ 5 seconds, fire extinguishing time ≤ 1 second. The validity period is up to 10 years.

Hot aerosol is a kind of smoke extinguishing agent. The fire extinguishing agent must be self-burned before the fire extinguishing agent can be released, which is accompanied by a thermal cascade reaction. The outlet temperature is above 80 degrees, and it produces harmful gases, the residue is corrosive and difficult to remove, and the smoke is large, which is not conducive to the escape of personnel. Because it is the ignition source itself, the second fire hazard exists. Many domestic industries have banned hot aerosols for fire protection.
