WOOD TREATMENT METHOD

摘要

The invention relates to the wood-working industry and can be used to ensure the biostability and water resistance of wood. In the wood treatment method, which comprises impregnating the wood with tall oil, the tall oil is pre-heated to a temperature of 180-220°C, then air is fed into the oil for 90-150 minutes, with the above-mentioned temperature being maintained, after which a dehydration catalyst is introduced in an amount of 0.5-3% of the tall oil mass, the tall oil is then maintained at a temperature of 200-250°C for 2-5 hours, after which the wood is impregnated at a temperature of 130-170°C for 10-60 minutes and then subjected to a heat treatment at a temperature of 155-185°C for 3-8 hours. The biostability and water resistance is increased, the mechanical strength of the wood is maintained and the method is made easier and less expensive to carry out.
