Birchwood pre-hydrolytic treatment effect on physical and mechanical characteristics of composite material obtained on its basis

Abstract

The effects of the birch wood pretreatment with hydrogen peroxide and its subsequent treatment by explosive autohydrolysis on the density, strength in static bending, water absorption and swelling of a composite material obtained on the basis of hydrolyzed wood pulp by hot pressing without the addition of binders are presented. The dependences of the density of the samples, their strength and hydrophobic characteristics on the amount used in the processing of hydrogen peroxide and the conditions of explosive autohydrolysis have been established. The threshold limit of hydrogen peroxide for each of the modes of explosive hydrolysis has been determined.
