<p>TITLE PROCESS OF CONVERTING LIGNOCELLUOSIC MATERIALS INTO RECONSTITUTED COMPOSITE PRODUCTS INVENTOR KUO CHENG SHEN A low cost process of converting lignocellulosic materials into reconstituted composite products, such as building boards, furniture boards, reconstituted lumber and moulded articles, with no addition of resin binders. The hemicellulose portion of lignocellulosic materials is decomposed and hydrolyzed by high pressure steam to generate free sugars,which can be chemically transformed by the application of heat and pressure,act as a thermoset adhesive binder, providing both a bonding and bulking effect. The reconstituted composite products thus produced possess good strength property and superb dimensional stability.</p> |
