The importance of chemical treatment for wood
Best quality wood goes, except for industrial and civil construction, in the production of railway sleepers and poles for electrical networks. In the late Soviet years, the total volume of timber, care for these purposes amounted to over 10 million. cu. m, being distributed approximately equally between the sleepers and pillars.
And accordingly was the level of chemical wood protection. Chemically untreated sleepers hardly used at all, and the level of treatment of supports of transmission lines exceeded 35%. Given the high burden that carries wood, used for these purposes, chemical protection deep impregnation was simply necessary - the life of untreated poles and railway sleepers in short about three times.
The defeat of wood by fungi - the scourge of the timber industry.
Taking into account the increased requirements that apply to the wood used for the needs of the construction and technological purposes, fungal lead at best to reduce the cost of lumber, and at worst - to their full culled and sent to processing. Therefore, the importance of the chemical processing of timber is difficult to overestimate. However, currently subjected to chemical protection, at best, every tenth of made in Russia more than 20 million. cu. m. of wood. This low rate is explained by several factors. The overall industry downturn has affected and in plants producing chemicals for wood protection - some of them even have ceased to exist, the others have sharply reduced production volumes.
The existing Soviet system of quality control and ordered to live long, and not created a new return it. In addition, timber manufacturers, with rare exceptions, care only about the growth of production and sales of products to fast, not about how many will serve its products.
However, the appearance on the market of new chemical materials and chemical processing of wood inspires some devices optimism - High competition in the lumber market should lead in the future to increase the share of processed wood.
