FIELD: process engineering.
SUBSTANCE: invention relates to woodworking industry. Proposed method consists in thermal impregnation with aqueous solution including nitrogen-containing component and borax. Said nitrogen-containing component represents carbamide at the following ratio of components in wt %: borax -10-1, carbamide - 10-15, water making the rest. Additionally, lime is used in amount of 20-30% with respect to amount of water. Proposed method comprises saturation of wood with aromatisers by injecting the latter into closed chamber with wood in amount of 1-2 g per 1 m3 of wood and holding it for 24 hours.
EFFECT: higher quality of treatment, longer life of wooden articles.
