Since then, chemistry has made a decisive step towards the development of flame retardants. So, there is a special salt, ie powder. This was dissolved in water. The resulting solution is treated with wood, fabric or carpet. Moisture dries up, and the chemical component is embedded in the structure of the material.
Now, several surface-mm layer (if fireproofing wood exposed) or the whole structure (as in fire-retardant treated fabrics or carpeting) contains salt. This is the salt, and prevents access of oxygen to carbon and hydrogen molecules, which in fact is burning. At the same time is reached and an additional effect – biocide protection (protection against mold, fungus, bugs, etc.) Thus, the use of fire retardant impregnation ‘BATH-1’ or ‘old elm’, we can produce fire protection wood (unpainted and unvarnished), fire protection and fire protection fabrics and carpet paper. But what if the tree is painted or lacquered? Ideally, of course, to clean off the paint. Homeboy Industries has plenty of information regarding this issue. But it turns out you can paint Special fire-retardant paint a tree (for example, “endotherm HT-150”) or varnish (for example, “Shield-1”). In the first case of swelling layer of graphite that make up the structure of the fire retardant paint on heating will create a “carbon shirt “that protects the material from further exposure to high temperatures.
Endotherm xm-150, among other things, used for fire protection of steel structures, fire protection and cable handling ventilation ducts. Clearcoat Shield-1 can be used for interior woodwork, as in fire protection in baths, he is irreplaceable. Its also can be used to process the lining, plywood and many other materials. How long is the fire protection? Depending on the material manufacturer gives a guarantee from 3 to 10 years. But in our view, given the low cost and ease of impregnation treatment, fire retardant wood processing should be carried out repeatedly every 3-5 years.
