Cups Surface
However, remember that the bass is most vulnerable to decay, so in most cases, log ostrugivayut. To protect the wood from rotting logs the entire surface is treated with a thin layer of antiseptic and flame retardant endotherm. And the ends of logs, the cups, the groove, cuts, Stroebe and place soaked proteski most carefully, as there are broken fibrous structure of wood. With antiseptic logs can give color shade customer's choice. Impregnation of wood from decay and fire is known, in addition to wood-organisms, the wood may be exposed to the ravages of fire, which is to some extent more intense destructive factor. In this regard, the task of fire protection of timber is not in doubt. To improve the fire resistance of wood is widely practiced by its treatment with special fire retardant paint – antipyretics. In this If fire protection is achieved through wood materials introducing into the timber the required number of chemicals that can interfere with a certain concentration of combustion without ignition source Flame retardant effect of flame retardants due to a combination of various physical and chemical processes occurring under the influence of fire on the wood.
It is based both on the melting of the fusible substances in their composition (Salts of boric acid, salts of phosphoric acids or silica), and the decomposition of substances which give off gases that do not support combustion (ammonia, sulfur dioxide). In the first case, the timber is formed by heating melted film, which limits the access of oxygen to the surface. The result – some of the heat expended on melting flame retardants, which increases the ignition temperature of wood, and, consequently, to protect it. In the second If the decomposition of salts are allocated non-combustible gases which displace oxygen from the wood surface, diluted evolved from the surface of combustible gases and thus prevent combustion.
