In order to improve the fire extinguishing performance of foam agents in nonpolar liquid fires, application alkyl amidopropyl betaine with different chain lengths aqueous film-forming was studied. The relationship between structure alkylamidopropyl and surface tension, foaming property stability analyzed. On this basis, agent formulations were formed, then each formulation tested. results show ...

This paper presents experimental research findings regarding the characteristics of fire safety equipment activation before and after a water-based suppression system is triggered. A group typical indoor combustible materials (wood, linoleum, cardboard, paper) were used to construct Class model fires in experiments. The three most frequent causes reproduced: careless handling (open flame), unsa...
