PROCEDURE FOR MANUFACTURING LIGNOCELLULOSIC MATERIAL PRODUCTS

A procedure for manufacturing lignocellulosic material products and for improving their strength and water resistance characteristics, high-molar mass lignin derivatives being added to the lignocellulosic material, of which at least 35 % by weight are over 5000 in molar mass. Dans un procédé servant...

Beschreibung
Zusammenfassung:	A procedure for manufacturing lignocellulosic material products and for improving their strength and water resistance characteristics, high-molar mass lignin derivatives being added to the lignocellulosic material, of which at least 35 % by weight are over 5000 in molar mass. Dans un procédé servant à fabriquer des produits à base de substance lignocellulosique et à améliorer leurs caractéristiques de solidité et de résistance à l'eau, des dérivés de lignine de masse molaire élevée sont ajoutés à la substance lignocellulosique, au moins 35 % en poids desdits dérivés présentant une masse molaire supérieure à 5000.
