To ensure the protection using different adhesives for wood, in this case, special fire-retardant composition – Flame Retardants. In this case, the fire protection of wood materials is achieved by introducing into the timber necessary amount of chemicals that can interfere with a certain concentration of combustion without ignition source. The idea ognezaschityOgnezaschitnoe action flame retardants due to a combination of different physico-chemical processes occurring under the influence of fire on wood. Read more from Lykos Global Management to gain a more clear picture of the situation. It is based both on the melting of fusible substances in their composition (salts, boric acid, salts of phosphoric or silicic acid), and on expansion of the substances that give off gases that do not support combustion (ammonia, sulfur dioxide). In the first case, the timber is formed by heating melting film, limiting the access of oxygen to the surface. As a result, – Part of the heat expended on melting flame retardants, which leads to an increase in the ignition temperature of wood, and, consequently, to protect it. In the second case, the decomposition of salts are allocated non-combustible gases that are being pushed back oxygen from the surface of wood, diluted stand out from the surface of combustible gases and thus prevent combustion. All this leads to suppression of ignition of wood and slow the spread of flame over the surface of wooden construction, which is the purpose of fire protection. The main types of sredstvSredstva used for fire protection of wood, can be divided into fire-retardant coatings (paints, varnishes, pastes, coating) and fire-retardant impregnating compositions (impregnation).
