Abstract

Moisture sorption processes carried out in successive steps in seven relative humidity environments between 11% and 92% at 20°C for Chinese fir (Cunninghamia lanceolata Hook.) and Sitka spruce (Picea sitchensis Carr.) were studied. A theoretical equation was developed to describe wood adsorption processes, either started from oven-dry condition or certain initial moisture content. The relation between adsorption rate constant in the equation and relative humidity was clarified as follows: with an increase in relative humidity, the adsorption rate constants for both species first decreased and then increased slightly with the minimum values falling into the relative humidity range between 60% and 70%. Further, an attempt was made to model the observed relation between the rate constant and relative humidity by applying the Hailwood-Horrobin sorption theory.
