The prepared ultra-fine dry powder extinguishing agent of embodiment 1-4 easily filling, carry and spray, its properties is detected, result is as shown in table 1:
Table 1 ABC ultra-fine dry powder extinguishing agent performance
The fire-fighting characteristic of the ultra-fine dry powder extinguishing agent that embodiment 1-4 is prepared is as shown in table 2 below:
Table 2 ABC ultra-fine dry powder extinguishing agent fire-fighting characteristic
By table 1,2, can be found out, prepared ultra-fine dry powder extinguishing agent 90% particle diameter of embodiment 1-4 is less than 12 μ m, and product quality indicator meets GA578-2005.And the fire extinguishing effectiveness that puts out A, B, C class fire is less than or equal to 90g/m
