A large number of fire extinguishing tests show that the reasonable selection of two or more fire extinguishing agents can combine the advantages of the fire extinguishing agents, and the effect is better than the use of a single fire extinguishing agent. The combination of fluorine protein foam extinguishing agent and dry powder extinguishing agent is a fast, reliable and effective fire extinguishing method for large oil fires, which can greatly reduce fire losses and achieve good social benefits. benefits and economic benefits. The fire extinguishing technology of fluorine protein foam extinguishing agent combined with dry powder can not only give full play to the advantages of foam fire extinguishing and dry powder fire extinguishing, but also overcome the defects of foam fire extinguishing delay and dry powder fire extinguishing. Reburning, to achieve a better fire extinguishing effect. This is because the surface tension of fluorine protein foam fire extinguishing agent is lower than that of fuel, which can not only resist the rupture caused by fuel, but also resist the pollution and destruction of dry powder, so as to achieve better fire extinguishing effect. Then, let's understand the problems of fluorine protein foam fire extinguishing agent that need attention!

Of course, when the fluoroprotein foam fire extinguishing agent is used in combination with the dry powder, only by choosing a better coordination method can the respective advantages of the fire extinguishing agent be brought into play to achieve a better fire extinguishing effect. When foam and dry powder are sprayed at the same time, the fire extinguishing effect is not ideal, which may be caused by the interference of foam and dry powder when passing through the flame zone. When a certain fire extinguishing agent is sprayed at the same time after a period of time, the effect is better than that of using fluorine protein foam alone. The test shows that the effect of spraying foam and dry powder at the same time after spraying foam for 5 seconds is better when the fire is basically controlled by half. This combination achieves the purpose of using a small amount of fire extinguishing agent to extinguish the fire.

Fluoroprotein foam fire extinguishing agent is a low-expansion foam fire extinguishing agent made of protein foam as the base material, adding a small amount of fluorocarbon and hydrocarbon surfactant. Compared with the protein foam fire extinguishing agent, the surface tension and interfacial tension are significantly reduced. Small shear stress, good fluidity, strong oleophobic ability, and strong anti-oil pollution ability, so that the fluorine protein foam extinguishing agent can extinguish the fire quickly (the extinguishing time is shortened by 1/31/2), and the liquid can be sprayed underwater to extinguish large oil tank The advantages of fire can be used in conjunction with dry powder extinguishing agent.

It can be mixed with water at a ratio of 3:97 or 6:94 in various low-power foaming equipment to produce foam. It is widely used in large-area oil fire fighting products in oil fields, oil depots, petrochemical enterprises, ships, airports and units storing a large amount of oil products. It is sealed and stored in a cool, dry and ventilated indoor environment with a storage temperature of -540 and a normal foaming operating environment of 040. Valid for two years.

Fluoroprotein foam fire extinguishing agent mainly has the following problems need to pay attention:

Minimize mechanical shock. Due to the strong mechanical impact, a large amount of foam will burst, thereby destroying the foam. Therefore, when spraying foam, it should be sprayed directly on the tank wall or other objects, do not impact the oil surface, try to spray along the tank wall close to the oil surface, so that the damage caused by foam is reduced to a low level. through mechanical action. Try to avoid high temperature damage. Because high temperature will have a certain destructive effect on the foam, when spraying the foam, try to avoid excessive flow of the foam through the high temperature tank wall, and pay attention to avoid the flame.

Speed up the process as much as possible. The use of foam to fight oil fires is mainly covered by the flow of the foam itself, so as to achieve the effect of fire extinguishing. In order to speed up the flow speed of the foam, the spray gun can be waved appropriately to make the foam fire extinguishing effect better.
