Embodiment 1
[0036] The fine water mist additive in the present embodiment adopts the formula listed in the table below:
[0037] Component mass percent concentration%
[0038] C 8 f 17 SO 2 F 6.0
[0039] Alkylphenol Ethoxylates 3.0
[0040] Urea 6.5
[0041] Triethanolamine 0.5
[0042] N-N-dimethylformamide 15.0
[0043] Sodium Lactate 1.5
[0044] water 67.5
[0045] The preparation steps are:
[0046] 1. The mass is 6.0% of the total mass of the solution C 8 f 17 SO 2 F is added to N-N-dimethylformamide whose mass is 15.0% of the total mass of the solution under slow stirring conditions, and stirred until completely dissolved;
[0047] 2. Waiting for C 8 f 17 SO 2 After F is completely dissolved, adding water with a quality of 67.5% of the total mass of the solution is diluted;
[0048] 3. Add triethanolamine with a mass of 0.5% of the total mass of the solution, urea with a mass of 6.5% of the total mass of the solution, and sodiu...
Embodiment 2
[0081] The fine water mist additive in the present embodiment adopts the formula listed in the table below:
[0082] Component Mass content%
[0083] (C 2 f 5 ) 2 C(CF 3 )=C(CF 3 )-OC 6 h 4 SO 3 Na 3.0
[0084] Alkylphenol polyoxyethylene ether 1.5
[0085] Urea 4.0
[0086]Triethanolamine 0.3
[0087] N-N-dimethylformamide 10.0
[0088] Sodium Lactate 1.0
[0089] water 80.2
[0090] Preparation process is with embodiment 1.
[0091] The effect that each component plays in the fire extinguishing process is the same as embodiment 1.
[0092] Experiment testing method is the same as embodiment 1.
[0093] C mentioned below 2 f 5 ) 2 C(CF 3 )=C(CF 3 )-OC 6 h 4 SO 3 Na% refers to diluting with water on the basis of the above formula, C 2 f 5 ) 2 C(CF 3 )=C(CF 3 )-OC 6 h 4 SO 3 The mass percentage of Na in the total mass of the concentrated solution and the diluted water added.
[0094] The surface tension...
