Thermal modification of high moisture round logs in the environment of saturated water vapor with simultaneous predrying

Abstract

The review of researches in the field of heat treatment of wood in Russia and abroad is carried out. The energy saving technology of thermal modification of high moisture round logs in the environment of saturated water vapor with simultaneous predrying is developed. The description of design of installation for realization of the offered technology is presented. The tests for determination of physical and chemical changes in wood during thermal modification were run. The results of tests and the regime parameters of conducting the process of thermal modification in the environment of water vapor for the purpose of receiving wood with the improved final characteristics are presented.

Evaluation of the Influence of the Conditions of Catalytic Continuous Steam Explosive Activation of Wood on the Physical and Operational Properties of Wooded Composite Materials Based on Activated Fibers

“…This activation method allows you to turn wood waste into a product suitable for the manufacture of board materials without the use of synthetic binders such as phenol-, urea-, amino-formaldehyde resins [13]. The use of wood waste to obtain non-toxic board materials opens up the prospect of developing resource-saving technologies that improve the environmental situation in the industry [14,15,16,17,18].…”
