Study on Water-based Fire Extinguishing Agent Formulations and Properties

Abstract This article uses the orthogonal experimental method to explore seven kinds of additives, including the fluorocarbon surfactant, hydrocarbon surfactant, chelating agents, anti-burning agents, emulsifiers, thickeners and antifreeze, with different content ratio of water-based extinguishing agent studying the impact of fire extinguishing performance. Get the best theoretical formula by using standard combustion room to simulate the extinguishing process of gasoline fire. The affect size of extinguishing time of those additives is hydrocarbon surfactant> chelating agents> fluorocarbon surfactant> emulsifiers> anti-burning agents> thickeners> antifreeze. According to the national standards for the test methods, the pH, stability, sediment, surface tension, fire performance of the best theoretical formula are consistent with the requirements of national standards. The article also verifies the feasibility of the orthogonal experiment method in dealing with such issues.
