 According to statistics, people on fire, killing at least all of the open fire. Poisoning by combustion products and the collapse of building structures - are the main causes of deaths. Of which would not have been made bearing elements of the building, they are very vulnerable to an open fire: a critical temperature is reached, if they do not burn, the deformed, causing the collapse. It is in order to increase the thermal resistance of the materials, giving, thus people time to get out of a burning building and there are flame retardants. Their second purpose - to prevent the spread of fire from room to room.
On what the methods and materials used for fire protection of building structures, which are the most common and effective, which brands have proved themselves in the market, we talk to suppliers of flame retardants and their customers - enterprises which are active fire protection solutions.
Distinguish constructive ways retardants (facing builders insulation materials, heat-reflecting device screens, etc.) and fire-retardant treatment which is performed with the use of special flame retardants (pastes, paints, lacquers, impregnation, etc.) by applying them to the surface structures materials, products, or location within the materials (flame retardants). This material experts give their opinions about the means of fire protection and fire-retardant treatment of wood technology, metal structures, concrete structures, as well as air and smoke exhaust systemsх.
 Babin Alexander, director of "Triumph":
«"In the construction of buildings and structures of the materials used, different in origin and class of fire hazard. Many of them need to fire protection. It is believed that the metal fire protection is not necessary - it's not lit. Indeed, steel structures do not burn and does not contribute to the spread of fire, but the 10-15-minute exposure to the fire, when a temperature of 500 degrees, lose bearing capacity. Fire protection is aimed at preserving the carrying capacity of steel structures.
There are two types of fire retardant paint on metal: plastering compositions and intumescent paint. Thick plaster compositions are applied to the material. Such coverage does not tolerate mechanical damage: over time paint "behind" crack from the blows. Action intumescent paints based on the composition and swelling caused by the formation of a porous insulating layer with a thickness of a few centimeters. It creates a kind of "coat" that prevents the effects of fire on the metal. The main advantage of intumescent paint is a low load on structures. The use of fire retardant paint reduces labor costs, and significantly reduce the time of fire protection works».
Gennady Popkov, director of "NeoKril":
«In fact, the choice of a flame retardant is not so simple, and the "case" is not only in the degree of brand awareness. For example, to protect wooden structures from fire used paint and impregnation (often it's just water and salt solution). Choose what to use - paint or impregnating, with the necessary goals to be achieved. The paint is guaranteed to hold for fifteen years, and even more. A water-salt solution is washed away with time, the guarantee of its fire protection - 3 years. On the other hand, the treatment is much cheaper than paint. So you should take into account, which will be the wooden structure. If the construction of the "zashyut" finish, then in that case it is better to use the paint - then will not need to open the design in order to repeat the process. Designated as available for re-treatment (for example, in the attic), it is better to protect preservatives.
It is worth noting, preservatives may vary. For example, the impregnation of the company "Nord" (Izhevsk) different specific composition - this is not a simple water-salt solution. Due to special processing aids, their term of flame retardant action more. That, of course, is reflected in a higher price. Consumers choose what is best for them - choose inexpensive impregnation and three years later to repeat the process, or buy a more expensive structure, but to repeat the treatment after 5-6 years.
In intumescent paint and plaster, used for fire protection of metal, has its pros and cons, and we can not say that the intumescent paint universal. After all, as a rule, they are certified by the fire until 1:00. If you need to provide greater fire resistance, better use of plaster compositions. They are, among other things, and is much cheaper. But if the process are design elements that define the appearance of the building (for example, open metal, column), it is preferable to take the paint. If you want to protect-beam ceilings, which will later be hidden trim, fit cheaper plaster composition. However, the material used for fire protection works, usually pre-specified by the designer, who is based at its choice of three main criteria - the degree of fire protection, aesthetics and cost.
On the market today domestic retardants and materials produced with sufficiently high quality, all products necessarily certified. Competition with foreign suppliers, which can be seen even 5 years ago is now gone "out": with comparable quality, the domestic product much less. However, changed the structure of imports: today manufacturers of flame retardants are used as raw materials imported components as well as the quality of the domestic production of chemical products, often leaves much to be desired.
Shlyakin, deputy director of the production company "Hi-Tech":
«The main direction of our work - fire protection of steel structures. Market trends today are: most customers it is important that the aesthetic requirements are met during the fire protection work.
Typically, the choice of fire-retardant paint or plaster, we focus on the domestic industry. The fact is, many imported paints have a strong odor, which is unacceptable when the work is done indoors. So now working with the domestic paint, which has a sharp odor and is therefore very easy to use.
 The main criteria by which we choose spetskrasku
aesthetics. The paint should have the property of coating material, which is particularly important in the processing of open building designs;
longer sticky (when applied must not leak;
flexibility (if the metal is subjected to any deformation, the paint should not peel). In addition, it is important that the paint was environmentally friendly, zero emissions - in fact it is used, for example, for fire protection in institutions.
As for the fire protection of building structures made of wood, then and there, we stopped at a special paint - it's more technologically than the use of impregnation. Another reason is that the preservatives are relatively inexpensive, and we, of course, more profitable to offer consumers a more expensive paint handling, besides having a much longer life. In addition, there are a number of materials, such as fiberboard, which are not impregnated.
To protect the ventilation system from the direct effects of fire retardants are used as a system consisting of basalt fiber and a special postmark, flame retardant. Basalt fiber and fire retardant sealant is non-flammable and non-toxic materials. High thermal resistance, can achieve the fire rating of 90 minutes with the weight of one square meter of fire protection 2, 5 pounds.
In the fire-retardant treatment of cables, ducts, smoke removal systems we use embor - basalt fireproof material, and paste "Triumph" (makes JSC «Tizol" N. Tura). We have already been working for a long time with the products of the manufacturer. I also commend the fire-retardant paint "Starprotek" produced "Center Fire Protection", Nizhny Novgorod.
For fire protection of concrete and reinforced concrete used materials with high thermal insulation capacity and high vapor permeability in order to ensure a slow warm-protected structure, in which the diffusion of water vapor did not cause significant internal stresses. Meet these criteria fireproof plaster on mineral binders with lightweight aggregates. Performed well flame retardant School-1. firm "Croze", Moscow.
Sergei Terekhin, Executive Director of "architecture":
«Our company is engaged in fire protection of steel structures. Depending on customer requirements and the required degree of fire resistance (1, 2, 3 or 4), we use or fire retardant membrane or paint.
We try to buy products from the same suppliers. Currently, the most widely use flame retardant weatherproof enamel SAO 5B (producer - SPE "Nylon", Yekaterinburg) designed to protect metal and ducts. If you want to ensure maximum fire protection action, the paint is applied in 3-4 layers. Pre-primed for paint CAO-07. Primer provides additional fire resistance for about 20 minutes.
How to determine the quality of a fire retardant paint? Do it without thinking very hard. If all of the technology of fire protection are met, metalwork degreased, cleaned of dust, applied primer and enamel, then two years later the paint should not "come off." And just did not check. Therefore it is better to purchase fire protection products from "trusted" supplier. |
