Materials for tissue has its own standard, under which the test results flammable textile materials are subdivided into flammable and inflammable. Impregnation Flame retardant BATH-1, developed and manufactured since 1993 JSC "Neohim." Originally produced as part of an aqueous solution, which, of course, was not effective, since the objects are processed composition, had to carry plenty of water. Recently BATH-1 is produced as a dry powder that is diluted on-site. When the superficial impregnation of wood allows you to transfer to the second group of flame retardant efficiency. Initially membership was created to handle the attics, which are just and should have such a group. And if we put the wood in the 20% solution of antiseptic tree, then within two hours of deep impregnation occurs, which translates the material in the first group of fire-resistance rating.
Impregnation under pressure – the most promising way to protect wooden structures. Wood "canned" impregnation solution penetrates it deep enough. When a surface impregnation, after rassushivaniya layer is destroyed, the protection disappears. And when the pressure impregnation is guaranteed "the integrity" in the cracks of up to 1.5 cm. At the same time – and this is important – on the mechanical properties of structures does not affect treatment. It is known that the first group of fire-resistance rating when using the impregnation depth is achieved only by means of an autoclave. If you make the surface impregnation – the tree will receive only the second group of fire-resistance rating. However, in most cases, a deep soaking to just impossible, not every design can be disassembled to such components to each could be loaded into a special bath. The firm "Antiseptic" offers impregnating compositions – Flame Retardants "PP", "MS" and "MC 1-1." All three are dry soluble products, the first two are for surface, and the third – for deep soaking. JSC "MORNING" produces impregnation of the "Old Elm" is also intended for surface impregnation.
