The mainstream storage foam container for foam fire extinguishing agent is mainly a special container made of steel, stainless steel or polyethylene plastic materials. At the same time, the inside of the foam liquid storage tank needs to use solvent-resistant paint to do the anti-corrosion treatment of the inner wall. And we must pay great attention to the fact that the aqueous film-forming foam and the anti-alcohol foam are more corrosive and have special requirements for anti-corrosion coatings. Great attention should be paid to them during storage. Pay attention to the actual storage: the foam tank storing the foam fire extinguishing agent should be filled as much as possible and ensured to be sealed.
Foam fire extinguishing agents generally cannot be pre-mixed. Once pre-mixed with water occurs, the validity period will be greatly shortened. Of course, there are some exceptions for foam fire extinguishing agents. For example, aqueous film-forming foam fire extinguishing agents can be stored in the form of raw liquid or mixed liquid. But this is only a few special cases. Other foam fire extinguishing agents can only be stored in the original liquid, and foam fire extinguishing agents of different types, different models or the same model, and different manufacturers cannot be mixed and stored.
The supplier of the fire extinguishing agent stainless steel foam storage tank reminds to maintain the environment of the storage place: specifically, to keep the storage place ventilated and dry to avoid direct sunlight, and to prevent the mixing of impurities and other substances. Regular inspection: The main purpose is to find and clean up those foam extinguishing agents that have deteriorated seriously, and to find and label those that have deteriorated but are not serious.
The fire extinguishing principles of foam fire extinguishing agents are as follows: (1) The foam fire extinguishing agent forms a foam layer on the surface of the burning material to isolate the burning material from the air to achieve the effect of suffocating and extinguishing fire; (2) The foam produced by the foam fire extinguishing agent will be carried in the foam Part of the moisture can physically cool the surface of the combustible; (3) The foam layer blocks the heat radiation of the flame to the surface of the combustible, reducing the evaporation rate of the combustible gas. It is also important to store the foam fire extinguishing agent properly to ensure good performance in all aspects during use.
