Water-borne Foam Fire Extinguishing Agents A foam fire extinguishing agent based on hydrocarbon surfactants and fluorocarbon surfactants and capable of forming a layer of water film on the surface of certain hydrocarbon liquids. Suitable for fighting fumes caused by water-soluble liquid fuels.
Water-borne foam fire extinguishing agent in the fire during the process of its foam layer of water can be formed in the fuel surface of the water film isolation and air contact and excellent mobility to quickly overwhelm the fire, put out the fire. At the same time it has a long closed performance and the advantages of anti-flame back to burn.
The water film is produced by the water-borne foam extinguishing agent because it contains a fluorocarbon surfactant which reduces the surface tension of the foam solution to float on the fuel surface. The effectiveness of the water film is directly related to the surface tension of the fuel, the surface tension of the higher fuel, such as diesel and aviation kerosene, the effect is lower than the surface tension of fuel, such as cyclohexane and gasoline better.
In short, the water film foam can be applied to the general non-suction device fire water gun and water spray equipment, but in order to get a better expansion times and liquid analysis time, all the foam should be used to inhale The device's foam gun and foam generation device.
The appearance of light amber
Density (20 ° C) 1.05 ± 0.05
PH value (20 ℃) 7.5 ~ 8.5
Viscosity (20 ° C) 15 ± 5 mPa · s
Minimum operating temperature (common type) -10 ℃
Minimum operating temperature (cold type) -30 ℃
The maximum operating temperature of 49 ℃.
Water-borne Foam Fire Extinguisher Ideal for transport, storage containers are made of original packaging containers or tanks and other containers specially designed for storage of this foam. The recommended container manufacturing material is stainless steel (Type 304L or Type 316) High-density cross-linked polyethylene resin or glass fiber reinforced polyester resin lined with vinyl ester coating (50 to 100 mils).
The foam will evaporate, especially when exposed to the air will accelerate the evaporation, the tank should be sealed and installed a breather valve to prevent the free flow of oil tank, the storage ambient temperature is recommended to maintain the range of -5 ℃ ~ 49 ℃ Inside. Product performance is not affected by freezing, melting.
Water film foam fire extinguishing agent in the storage, packaging, use should pay attention to the cleaning of the container can not be with other types of foam fire extinguishing agent, acid and alkali impurities mixed. Because this mixture will cause chemical changes in the product weakened or even the loss of fire fighting capacity. But it can be used with most of the foam foam in the fire fighting process. Also suitable for compatibility with the combination of dry powder fire extinguishing agent, you can fight the fire together.
