摘要：
Subjecting lignocellulosic components coated with an aqueous alkaline phenolic resole resin solution to carbon dioxide inhibits overpenetration of resin and improves bond strength when the coated components are heated to cure the resin by application of steam and pressure in the preparation of structural panels. Also, contact with carbon dioxide of high moisture resin coated lignocellulosic components accelerates the speed of cure and improves bond strength of panels cured under heat and pressure.
