Abstract

1,164,689. Dimensionally stabilised wood. MO OCH DOMSJO A.B. 25 Aug., 1967 [26 Aug., 1966], No. 39301/67. Heading D1P. Wood is treated with 10-25% of polyalkylene glycol and 0.5-20% of glyoxal as an aqueous or organic solvent solution. The glycol may be diethylene, triethylene, dipropylene, or tripropylene glycol. The glyoxal (which effects cross-linking) may be in the form of glyoxal-sodium bisulphite or partially polymerised glyoxal. A catalyst, e.g. acetic or sulphuric acid or sodium bisulphate, may be used. The solution may also contain methyl, carboxymethyl, hydroxyethyl, methyl-hydroxyethyl, ethyl-hydroxyethyl, or ethyl-hydroxypropyl cellulose; polyvinyl alcohol; collagen; or casein. The moisture content of the wood being treated may exceed the fibre saturation point. Treatment may be by spraying or vacuum and/or pressure immersion.
