Fire foam is sometimes required during construction work. It has many advantages. For some time, the material is able to withstand an open flame, and also maintain its quality characteristics. If you do not protect some objects with such a composition, their integrity may be violated, which is sometimes completely unacceptable.
Area of use
Fire foam is used today in many areas of industry and construction. Choosing such material, you must take into account the moment that it can be designed for a certain period of fire fighting. If we are talking about industrial buildings with fairly high requirements for fire resistance, then the specified time should be maximum.
Fire foam is used when it is necessary to fill the seams and cavities of stoves and fireplaces. Sometimes it becomes necessary to consolidate communication networks, where this material also comes to the rescue. With it, you can close the holes in the areas of exit or transition of heating pipes, as well as ventilation and water supply. Foam helps with the installation of door and window structures in pools, baths and saunas. You can use it when filling the cavity in the exit zone of the chimney or fireplace equipment. Before you purchase fire-fighting foam, you need to pay attention to the flammability and availability of certificates.
Features of the use of fire fighting composition
Initially, you must have prepared a 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. Further, the surface should be well moistened with water. As the most suitable temperature for these works can be called 20 degrees. If the foam bottle has remained in the cold for some time, then it must be kept indoors for several hours before use. After packaging, it should be lowered into warm water. However, it is not worth heating the package to more than 50 degrees.
Foam mounting fire before direct use should be mixed, for this it must be shaken for about a minute. Next, the foam is installed on the mounting gun upside down. The package must not tilt or spin in different directions. Fill the seams with foam only 1/2 volume. If you have to work with a vertical area, then the sealant must be applied from bottom to top. On top of the foam should be sprayed with water. However, the formation of individual drops cannot be allowed.
Technical specifications of some fire fighting compounds
If we are talking about fire-resistant foam brand Nullifire FF 197, it must be remembered that it is designed to fill the joints in those rooms that have high fire safety requirements. It is often used in the construction of refractory projects. This foam mounting fire has excellent insulating, sealing and insulation characteristics. It is characterized by excellent adhesive qualities.
Among its features, it can be distinguished that it has a fire resistance class B1. The material is capable of holding an open flame for up to four hours. The volume of the original cylinders is 880 milliliters. After applying the foam, it will show qualities of resistance to precipitation and all kinds of chemical reagents, which is especially true in industrial conditions.
Features of the foam brand "Macroflex FR 77"
Macroflex fire-fighting foam has the qualities of a professional one-component sealant. The material hardens when exposed to moisture. He is also able to undergo exposure to open fire for four hours. You can store the foam for about a year and a half. The most suitable temperature for application is 20 degrees. After hardening, the material has a medium-pore structure. In order for the composition to reach the final state suitable for use, it will take 12 hours. However, the master can make the initial processing after 20 minutes.
Features of fireproof foam "Titan"
Fire foam, the characteristics of which are presented in this article, has excellent adhesion to materials of various structures. Among its qualitative characteristics, fire resistance, thermal insulation abilities, as well as strength can be distinguished. Already half an hour after application, the foam can be subjected to primary processing, if the need arises. While complete drying occurs in a day.
The material is resistant to moisture and mold. It is not afraid of toxic gases and has a red color. You can use the material at minus temperatures from -5 degrees. At the polymerization stage, the foam can settle to a volume of 3 to 5 percent, this must be taken into account when applying. Fire-resistant compositions do not have very good adhesion with polyethylene, silicone, and also Teflon. Polyurethane foam mounting foam after hardening needs protection from exposure to ultraviolet radiation.
additional characteristics
It is important to consider all the features before using the described compositions in order to avoid possible problems. Thermally expanding fire foam should 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 to the base, if necessary. It is recommended to have a cleaning agent on hand.
If the cylinder is heated above the temperature mentioned above, there is a risk of an explosion. If it was left in the summer in the car, it must be cooled in water before use. Periodically, the cylinder should be shaken, which will allow it to reach the desired temperature.
Foam Wizard Recommendations
Polyurethane foam polyurethane foam Nullifire (this applies to other brands) should be used according to a certain technology. It is important to exclude the possibility of overfilling of joints. Fresh traces of foam must be removed exclusively with PU Cleaner. Moisturize the surface of the composition after application is necessary 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 opened the bottle with foam, but did not use it completely for the first time, you need to work out the entire remaining volume within four weeks. After this period, it will no longer be possible to use the composition, since it is considered unsuitable.
Fire Foam Cost
The described material can be purchased 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 present more expensive products. Thus, you may have to pay 500 rubles for 750 milliliters.
You can choose for yourself the manufacturer whose goods will suit you not only at cost, but also on quality characteristics. That is why before purchasing it is necessary to study the entire range of products that are on the market. Do not overpay for that foam, the temperature limit of which is higher than required. In some cases, the required volume of material is large enough, while the savings on foam can be very impressive if you choose the right quality characteristics.
