Fire-fighting foam: characteristics and application

Fire protection foam is sometimes required for construction work. It has a lot of 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, then their integrity may be violated, which is sometimes completely unacceptable.

Scope of use

Fire-fighting foam is used today in many areas of industry and construction. When choosing such material, you should take into account the moment that it can be calculated 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 the maximum.

Fire-fighting foam is used when filling joints and cavities of stoves and fireplaces. Sometimes there is a need to seal the communication networks, where this material also comes to the rescue. With its help, it is possible to seal holes in the exit or transition zones 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 the cavity in the exit zone of the chimney or fireplace equipment. Before you get a 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 should prepare a surface, which must be treated with a fire-fighting compound. To do this, the base is cleaned of oil stains, dust, all kinds of dirt, as well as greasy marks and debris. Then the surface should be well moistened with water. As the most suitable temperature for these works can be called 20 degrees. If the balloon with foam for some time remained in the cold, then it must be kept in the room for several hours before use. After the packaging, it must be lowered into warm water. However, heat the packaging more than 50 degrees is not worth it.

Foam mounting fire before direct use should be mixed, for this it should be shaken for about a minute. Then the foam is installed on the mounting gun upside down. Packaging should not bend or turn in different directions. Fill seams with foam only by 1/2 volume. If you want to work with a vertical area, the sealant must be applied from the bottom up. Over foam should be sprayed with water. However, you can not allow the formation of individual drops.

Technical characteristics of some fire-fighting compounds

If it is a fire-fighting foam of the brand Nullifire FF 197, it must be remembered that it is designed to fill joints in those rooms to which high fire safety requirements are required. It is often used in the construction of refractory projects. This foam installation fireproof has excellent insulating, sealing and thermal insulation characteristics. It is characterized by excellent adhesion qualities.

Among its features can be identified that it has a fire resistance class B1. The material is capable of holding open fire for up to four hours. The volume of the original cylinders is 880 milliliters. After the application, the foam will exhibit the qualities of resistance to precipitation and various chemical reagents, which is especially important in the industrial environment.

Features of the foam brand "Macroflex FR 77"

Fire-fighting foam "Makrofleks" has the qualities of a professional one-component sealant. The material hardens under the influence of moisture. He is also able to undergo the effect of 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 curing, the material has a medium porous structure. In order for the composition to reach the final state suitable for operation, it will take 12 hours. However, the master can perform the initial processing after 20 minutes.

Features of fire-fighting foam "Titan"

Fire-fighting foam, the characteristics of which are presented in this article, has excellent indicators of adhesiveness to materials of various structures. Among its quality characteristics can be distinguished fire resistance, thermal insulation ability, as well as strength. Half an hour after application, the foam can be subjected to primary treatment, if necessary. Then the complete drying takes place in a day.

The material is resistant to moisture and mold. He is not afraid of toxic gases and has a red color. Use the material can be at minus temperature of -5 degrees. In the polymerization stage, the foam can settle at a volume of 3 to 5 percent, this must be taken into account when applying. Fire-resistant compounds have not very good adhesion with polyethylene, silicone, and Teflon. Foam mounting fire-resistant polyurethane after hardening needs protection from ultraviolet radiation.

additional characteristics

It is important to take into account all the features before using the described compositions to avoid possible problems. Thermally expandable 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 desirable to apply a primer coat on the substrate, if necessary. It is recommended that you have a cleaner at your fingertips.

If the cylinder is heated more than 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 can should be shaken, which will allow it to reach the desired temperature.

Recommendations of the wizard for the use of foam

Foam mounting fireproof polyurethane Nullifire (this applies to other brands) should be used by a certain technology. It is important to exclude the possibility of overflowing the joints. Fresh foam marks should only be removed with a PU Cleaner cleaner. Moisten the surface of the composition after application in an optimal amount. If you feel sorry for the water, it can lead to cracks. Among other things, the composition may expand unnecessarily after the manufacturer's period. If you opened a can of foam, but did not use it completely for the first time, you need to work out the remaining volume for four weeks. After this period, the composition will no longer be available, since it is considered unfit.

Cost of fire foam

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, the price can be reduced to 330 rubles. Some manufacturers are 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 for value, but also for quality characteristics. That is why before buying it is necessary to study the entire range of goods, which is presented on the market. Do not overpay for the foam, the temperature limit of which is higher than required. In some cases, the required amount of material is large enough, while the savings on foam can be very impressive, if you choose the right characteristics.
