Abstract:

The paper presents an overall and systematic introduction of the main influencing factors and improving measures of wood permeability according to the significant effect of wood permeability on effective processing and optimal utilization of wood, and also proposed their main development trends, respectively. The advanced technologies for observation such as SEM-EDX, TEM, FTIR, NRM and CT should be fully used to deeply analysis the main penetrating channels of wood and resultantly to assure the major influencing factors exactly. And in order to further improve the permeability of wood, it is necessary to combine several technologies or exploit a new multi-functional and integrative technology about impregnating technology of wood.

Key words: wood, permeability, impregnation, controlling factors, improving measures
