Mechanism of Water Sorption during Adsorption Process of Wood Studied by NMR

Abstract

Abstract:

The changes of T₂ of water absorbed to wood in an environment of constant temperature of 32 ℃ and relative humidity of 98% was studied and used to reflect characteristics of water distribution and migration. The migration behavior of water molecules were used to explain the interactions between wood and water, and reveal the mechanism of water sorption at the microscopic level. The results of this study suggested that NMR is an effective tool to study the complex relationship between wood and water.

Key words: NMR, adsorption, T₂, water sorption
