Abstract
Vynález se týká způsobu modifikace dřeva. Jeho cílem je zvýSení jakosti modifikovaného dřeva. Uvedeného cíle se dosahuje tím, že se dřevo nasycuje vodným roztokem termoreaktivní pryskyřice, suší se a vytvrzuje se v prostředí kapalného nosiče tepla, přičemž sušení a vytvrzování se provodí za vakua při tlaku 40 až 110 mm rtutového sloupce, sušení se provédí při 40 až 85 °C a vytvrzování se děje při 110 ež 140 "C.The invention relates to a method of modification wood. Its aim is to increase the quality of the modified wood. This goal is achieved by getting wood saturates with thermoreactive aqueous solution resin, dried and cured in the environment a liquid heat carrier, while drying and curing is carried out under vacuum at a pressure of 40 to 110 mm of mercury, drying at 40 to 85 ° C; curing occurs at 110 to 140 ° C.
