内容記述(抄録等)
Infrared spectrum, JIS color difference and tensile strength of corona treated wood were measured and fracture texture was obseryed, to investigate the effect of corona treatment on wood properties. The experiment was done using Hinoki(Chamaecyparis obtusa ENDL.) of strip and quarter sawn panel of which thickness were 30μm and 2.5mm respectwely. For electrode, gap was 7mm, and applied voltage was from 9 to 15 kV, 60Hz, in nitrogen or air.
The absorbance of carbonyl group(1730cm^<-1>) increased with an increase in the degree of corona treatment in spite of the corona discharging atmosphere. It was considered that the post oxidation occured in the nitrogen corona.
It was expected that the surface roughness of wood increased with an increase in the JIS color difference, but that was not confirmed with the secondary electron images.
The tensile strength of wood strip decraesed linearly with an increase in the square root of the degree of treatment. By the observation of fracture texture, it was also shown that the longitudinal strength of cell wall decreased.
