Foam extinguishing agents commonly used to put out oil tank fires are: ordinary protein foam, fluorine protein foam and "light water" foam. Then, let's learn about the fire extinguishing efficiency of fluorine protein foam extinguishing agent!

Common protein foam fire extinguishing agent is widely used in petrochemical fire fighting in China. The main advantages of ordinary protein foam are good stability (25% liquid analysis time is long), low water quality requirements, and its main disadvantages are: poor fluidity, slow fire extinguishing speed; low anti-oil pollution ability, and low fire extinguishing efficiency among the three fire extinguishing agents.

Due to the effect of fluorocarbon surfactant, the fire extinguishing performance of fluoroprotein foam fire extinguishing agent is greatly improved. The foam has good fluidity and fast fire extinguishing speed; it has strong anti-oil pollution ability, and can be used to extinguish large oil tank fires by immersion spraying.

The main advantages of the fluorine protein foam fire extinguishing agent produced by our company are: good fluidity, and the thickness of oil surface accumulation is only 1/3 of that of protein foam. It can spread rapidly and cooperate with the water film to make the flame extinguish faster; it can also be used to extinguish the oil tank fire by immersion spray.

Price and shelf life of fluoroprotein foam fire extinguishing agent

Extinguishing large tank fires requires a lot of foam. Due to the different fire extinguishing effect and composition of fluorine protein foam fire extinguishing agent, its price also varies greatly. In addition, the shelf life of different fire extinguishing agents is also different. The price of fluorine protein foam fire extinguishing agent is higher than that of protein foam, and the price of water-based film-forming foam is high. Under normal storage environment, the shelf life of fluoroprotein foam extinguishing agent is 2 years, and the shelf life of water-based film-forming foam is longer, more than 8 years.

Influence of Water Source on Foam Extinguishing Agent

Fresh water is the source of water for all types of foam mixtures. However, under special circumstances, such as a fire in a large oil tank area located on the sea, it is very likely that seawater will be used to configure the foam mixture. According to Article 2.1.4 of the Code for Design of Low Expansion Foam Fire Extinguishing System, the water source for preparing foam mixture shall meet the following requirements: protein, fluorine protein and anti-solubility fluorine protein foam extinguishing agent, which can be prepared into foam mixture, and fresh water or seawater can be used; for all kinds of foam liquid, when configured as foam mixture, it is forbidden to use water that affects the fire extinguishing performance of foam;

Compatibility of Fluoroprotein Foam Fire Extinguishing Agent

Different types of foam extinguishing agents or the same type of foam extinguishing agents made by different processes cannot be mixed. Because mixing with each other will lead to the deterioration of its surface and interface properties, precipitation, turbidity and other phenomena, thus significantly reducing the foam performance. When fighting large oil tank fires, the use of the same extinguishing agent is better than the simultaneous use of multiple foam extinguishing agents.
