Using fire and bioprotective agents

Fire retardant treatment is a special type of work that allows you to create a fire-resistant coating that reduces the risk of fire, and also prevents ignition under conditions of prolonged exposure to fire and high temperatures. Especially important is the use of fire and bioprotection for wood and wooden structures that carry a load and / or are part of any supporting structure, or form a room for storing combustible materials.Wood fire protection

Fire bioprotection for wood is used not only for the processing of fuel and lubricants warehouses, hangars for warehousing and storage of wooden products. The risk of ignition is always high in granaries, stables where hay and straw are stored, in warehouses for seeds and printing products, in printing houses, or in rooms with a large accumulation of varnishes, paints, for example, art workshops or workshops for the production of furniture and other woodworking.

Certification

Fire-retardant materials are certified according to two main fire safety groups: 1st and 2nd.

  • The 1st group provides resistance to wood combustion and weight loss of no more than 9% for the time agreed in the fire safety documentation.
  • Group 2 provides fire resistance and weight loss of 9-25% in the same time. Fire-retardant materials are used not only in relation to wooden, but also metal structures.

Types of flame retardants

Modern fire and bioprotection for wood involves the use of impregnations, paints, varnishes containing fire retardants - substances that make the wooden surface slow-burning and self-extinguishing for a long time. This is achieved in several ways, which we will discuss in more detail below.

Wood fire retardant paint

The composition of the Bionic-House composition refers to flame retardants of the intumescent type. That is, when exposed to fire, it swells, forming a thick layer of non-combustible foam coke, covering the wooden surface from oxygen and fire. With active combustion, the coating is charred and does not allow open fire to penetrate to the surface of the tree, and when the source of fire is removed, it self-extinguishes.

Fire retardant paint after testing
Bionic House fire-retardant paint provides the 1st group of fire protection, having a very long effective life - over 10 years. In addition, it has an excellent degree of adhesion to wood, it is applied in 2 layers to achieve a total thickness of all layers up to 1mm. If the expert examination did not reveal cracks, chips and surface defects of the coating, then subsequent processing can be carried out much later.

If minor and not widespread defects are identified that can be cleaned and primed, tinting can be carried out on an old layer of the same paint without removing the previous coating over a large area. After complete drying and hardening of the treated surface, according to the time specified in the instructions for use, as well as upon reaching a thickness of 1 mm in the restored areas, the fire-retardant properties of the coating can be considered restored.


Impregnation by Bionic House has a double effect at once. On the one hand, it serves as an excellent antiseptic against biodestruction, prevents the appearance of mold and fungus, and on the other hand, it does not allow wood to burn when fire occurs. In fact, impregnation from Bionic House is fire and bioprotection in one composition. Fire-retardant treatment with our impregnation ensures the production of slow-burning wood when exposed to open fire and self-extinguishing in its absence, which corresponds to the 1st fire protection group.

Fire retardant impregnation

The introduction of flame retardants into wood through impregnation is a preventive measure for sawn, planed, sanded, that is, uncoated wood. Bionic-House fire-retardant impregnation is developed on a phosphate basis, has a good penetrating ability, and is used only for interior work or surfaces under cover, where there is no direct exposure to moisture and sunlight. It is quite suitable for processing household premises, wooden utility blocks, ceilings and attics of garages, summer kitchens, etc.

The term of effective impregnation protection is about 4 years. Its main advantages are price, versatility of use and reduced smoke generation in case of fire. All fire and bioprotective compositions of our company do not contain strong toxic and toxic substances and are as safe as possible for health.

fire protection wood

The use of fire and bioprotective agents for the production of industrial, construction and even household products is hotly discussed today, both by the Internet community and by chemical industry specialists. In some cases, fire bioprotection for wood is provided for by state standards, in some it is not. The use of flame retardants - flame retardants, has both its supporters and opponents.

An objective discussion of this issue by a wide range of interested people is complicated by specialized terminology and the fact that the components of fire-retardant compositions have a complex chemical structure. Depending on the conditions, the structure changes its shape, properties and requires a fairly deep knowledge of chemistry and medicine, biology and botany, as it affects the impact of different groups of chemicals on nature and human health.


Today, few people dispute the opinion that fire and bioprotective treatment cannot be both safe (non-toxic) and effective at the same time. Proposers of something like this will have a lot of reservations or reticences with a deeper interest in the chemical composition of their products. In addition, absolutely ALL fire retardants have very active chemical components that react with different substances or materials depending on the environmental conditions, and complicate the further processing or operation of certain types of coatings.

It is worth mentioning here that solid wood houses are prone to cracking and even the most thorough fire retardant impregnation sometimes becomes meaningless.

In order to provide maximum fire protection, a biomaterial such as wood needs industrial conditions. For example, in order to provide fire protection of groups 1 and 2 (fire resistance conditions according to state standards), about 350-600 ml / m2 of salt-acid fire protection should be introduced into the surface of the wood.

Effective fire protection by industrial method

At home, this is unrealistic, since the substance must penetrate into the tree to a depth of more than 8-10 mm, without high-pressure autoclaves or industrial equipment for pricking - this is not achievable. A simple fire retardant treatment of wood by rubbing or spraying is a self-soothing job with a meager effect.

Another disadvantage of water-soluble flame retardant impregnations for wood is the lack of protective properties from moisture and sunlight. Flame retardants do not protect wooden panels from fading in the sun and do not protect timber and logs from moisture.

Most water soluble fire retardants apply only to untreated wood, wash out with water and have a real fire-fighting effectiveness of 2-3 years maximum. This is a problem for owners of wooden houses, since modern wood finishes cost 5-8 years, and fire safety is only the first 2-3 years. If you want to update the fire protection coating, first remove the paint completely, as water-based fire protection impregnations do not work on paintwork.


When building wooden load-bearing structures and erecting wooden floors, it is often necessary to use fire protection for wood, which is designed to solve two problems:

  • The first is bioprotection against fungus, mold, insects.
  • The second is fire protection that reduces the possibility of fire, but does not exclude it.

Currently, there are two types of fire and biological protection for wood:

  1. Organic based (generally more effective). For example, compositions of pentaerythritol, melamine, polychlorophenol, phenol alcohols, organosilosanes, with the formation of phenol-formaldehyde resin, including most organic flame retardants containing halides (halogens) - substances where fluorine, chlorine, bromine, iodine are found in the names of the components. Halides

  2. Water based (generally less toxic). For example, phosphates, borates usually do not contain halogens and are mainly salts and inorganic acids containing phosphorus or boric acid.

Regarding the former, it can be said that their composition is toxic and applicable in "increased flammability conditions" and places remote from living space, where the cost of stored products or buildings is justified by high value. For example, museums, architectural monuments, libraries with ancient valuable books, jewelry warehouses, etc.

For reference: For example, bromine-containing fire retardants contain 65-70% bromine, which has a stable stable state at room temperature. If the bromine content reaches at least 0.001% of the total air volume, irritation of the mucous membrane will begin, possibly headaches, dizziness, and with a long stay - nosebleeds!

Water-based protection (Group 2) has become much more widespread. In this case, the biocomposition can be easily washed out, medium washed out, difficult to wash out. The basis of water-soluble fire protection is salts of phosphoric, silicic, boric and other acids. They are less toxic, but also less effective. To ensure a fire-fighting effect, a strong saturation of absorbent surfaces is required, as previously mentioned, about - 350-600ml/m2.

When wood is impregnated, a protective crystalline layer is formed, which makes it difficult to ignite and burn wooden elements (rafters, battens and partitions). Reagents of this group are ineffective against bioinfestation by mold, rot, fungus and have a temporary short duration. It is these fire-retardant impregnations that are offered in large quantities to the buyer in retail.


What is flame protection and what determines the effectiveness of impregnating compounds for wood?

There are several types of reaction of fire protection coatings to ignition:

  • Gasing (when the crystalline layer is heated) reduces the level of oxygen and inhibits the propagation of combustion. When ignited, flame retardants decompose and heat is absorbed, and when exposed to temperature, a non-combustible gas is released.
  • Formation of a coke layer: in this case, under the influence of fire, the decay of the impregnated wood is greatly retarded by the formation of non-combustible gas. The reaction flows into a chemical process towards the creation of a slow-burning protective coke residue, which slows down the ignition.
  • Foaming coke-forming impregnations - when expanded, foam is formed in the form of a fur coat, which makes it difficult to burn. The reaction ends with the creation of a heat-shielding film-coke layer on the surface, which prevents the ingress of oxygen, which in turn complicates the combustion process.

Quite often there is a fire bioprotection for wood, combining a mixed type of impact. Water-soluble protection containing acid salts is designed for a period of one to three years, on organic matter - up to five years. At the same time, the impregnation is often done in color so that the treated surface can be seen.

Treatment of wood with flame retardants worsens its decorative side. When painting, there may be a violation of the color scheme, discoloration, efflorescence under the paint, etc. Therefore, a high-quality, well-balanced fire and bioprotection agent does not violate the wood fibers, while maintaining its main functions. As mentioned earlier, not all flame retardants have a sufficient level of bioprotection, moreover, many of them impair the absorbency of wood. In this case, antiseptic treatment is also needed to protect the tree from rot or mold.

Expediency of complex means

There is another way to protect wood from fire - applying a coating on an organic or inorganic binder (paints, varnishes).

To combine decorative and fireproof properties, fire-retardant paint and varnishes are sometimes used. Sometimes this is a good solution to “kill 2 birds with one stone”, but it should be borne in mind that in order to resume the fire-protective properties of wood, you will have to sand the surface clean each time, since flame retardants are effective when applied only to bare wood.


Conclusions: In the end, everyone decides for himself whether fire protection is necessary in his particular case or whether it is enough to prevent the appearance of mold, rot and insects.

New

Effective fire retardant coatings are intumescent type coatings that create a barrier to heat conduction. The swelling process is a softening of the components, with the simultaneous decomposition of flame retardants and gas-forming components under the influence of temperature. At the same time, fillers (mainly mineral) are added, which contribute to the formation of a dense ball of foam coke, which creates the fire-retardant properties of the coating.

Most coatings of this type are water-based, which makes them low-toxic. Thus, the use of mineral substances makes it possible to develop a new type of fire-retardant coatings for building structures, the presence of which will slow down the heating of the material and maintain its functions during a fire for a given period of time.
