Fire-fighting foam is sometimes required during construction work. It has a lot of advantages. For some time, the material is able to withstand an open flame, as well as retain its quality characteristics. If you do not protect some objects with such a composition, then their integrity may be violated, which is sometimes completely unacceptable.
Use area
Fire-fighting foam is used today in many areas of industry and construction. When choosing such a material, you must take into account the fact that it can be designed for a certain period of fighting fire. If we are talking about industrial buildings with sufficiently high requirements for fire resistance, then the specified time should be maximum.
Fire-fighting foam is used when it is necessary to fill the seams and cavities of stoves and fireplaces. Sometimes there is a need to compact communication networks, where this also comes to the rescue.material. It can be used to close holes in the exit or transition areas of heating pipes, as well as ventilation and water supply. Foam helps with the installation of door and window structures in swimming pools, baths and saunas. You can use it when filling a cavity in the exit area of a chimney or fireplace equipment. Before you purchase fire-fighting foam, you need to pay attention to combustibility and the availability of certificates.
Features of the use of fire-fighting composition
Initially, you must prepare the surface that needs to be treated with a fire-fighting compound. To do this, the base is cleaned of oil stains, dust, all kinds of contaminants, as well as greasy traces and debris. Next, the surface should be well moistened with water. As the most suitable temperature for carrying out these works, 20 degrees can be called. If the foam container has been left in the cold for some time, then it must be kept indoors for several hours before use. After the container should be lowered into warm water. However, you should not heat the package more than 50 degrees.
Fire-fighting assembly foam must be mixed before direct use, for this it must be shaken for about a minute. Next, the foam is installed on the mounting gun upside down. The packaging must not tilt or twist in different directions. It is necessary to fill the seams with foam only 1/2 of the volume. If you have to work with a vertical area, thensealant must be applied from the bottom up. On top of the foam should be sprinkled with water. However, separate droplets cannot be allowed to form.
Specifications of some fire fighting compounds
When it comes to Nullifire FF 197 fire-fighting foam, it must be remembered that it is designed to fill joints in those rooms that have high fire safety requirements. It is often used in the construction of refractory projects. This mounting fire-fighting foam has excellent insulating, sealing and insulating characteristics. It has excellent adhesive properties.
Among its features, it can be distinguished that it has a fire resistance class of B1. The material is able to hold open fire up to four hours. The volume of the original cylinders is 880 milliliters. After application, the foam will show the qualities of resistance to precipitation and all kinds of chemicals, which is especially true in industrial conditions.
Macroflex FR 77 foam features
Fire-fighting foam "Macroflex" has the qualities of a professional one-component sealant. The material hardens on exposure to moisture. It is also capable of being exposed to open fire for up to four hours. You can store foam for about one and a half years. The most suitable temperature for application is 20degrees. After hardening, the material has a medium-porous structure. It will take 12 hours for the composition to reach the final state suitable for operation. However, the master can perform the initial processing after 20 minutes.
Features of fire-fighting foam "Titan"
The fire-fighting foam, the characteristics of which are presented in this article, has excellent adhesion to materials of various structures. Among its qualitative characteristics, one can single out fire resistance, thermal insulation abilities, as well as strength. Already half an hour after application, the foam can be subjected to primary processing, if such a need arises. Whereas complete drying occurs in a day.
The material is resistant to moisture and mold. He is not afraid of toxic gases and has a red color. You can use the material at sub-zero temperatures from -5 degrees. During the polymerization stage, the foam may shrink by volume from 3 to 5 percent, this must be taken into account during application. Flame retardant compounds do not have very good adhesion with polyethylene, silicone, and also Teflon. Fire-fighting polyurethane assembly foam after hardening needs protection from ultraviolet radiation.
Additional Features
It is important to take into account all the features before using the described compositions in order to avoid possible problems. Thermally expandingfire-fighting foam must be used under certain conditions. In addition to the above, it is worth considering that the surface to be treated must be solid. It is advisable to apply a primer layer on the base, if necessary. It is recommended to have a cleaning agent on hand.
If the cylinder is heated above the temperature mentioned above, then there is a risk of an explosion. If it has been left in the car in the summer, it must be cooled in water before use. Shake the bottle periodically to allow it to reach the correct temperature.
Recommendations of the master on the use of foam
Fireproof polyurethane mounting foam Nullifire (this also applies to other brands) must be used according to a certain technology. It is important to exclude the possibility of overfilling the seams. Fresh traces of foam must only be removed with PU Cleaner. It is necessary to moisten the surface of the composition after application in the optimal amount. If you spare water, this can lead to cracks. Among other things, the composition may expand unnecessarily after the period allotted by the manufacturer. If you have opened a can of foam but did not fully use it the first time, use up the rest of the volume within four weeks. After this period, it will no longer be possible to use the composition, as it is considered unsuitable.
Fire fighting foam cost
You can buy the described material at a price of 350 rubles for 880 milliliters. This price is retail. If there is a need to purchase foam in large quantities, then the price can be reduced to 330 rubles. Some manufacturers provide more expensive goods. Thus, you may have to pay 500 rubles for 750 milliliters.
You can choose for yourself the manufacturer whose product will suit you not only in terms of cost, but also in terms of quality. That is why before purchasing it is necessary to study the entire range of goods that are on the market. You should not overpay for that foam, the temperature limit of which is higher than required. In some cases, the required amount of material is quite large, while saving on foam can be very impressive if you choose the right quality characteristics.
