영문 초록

To investigate weathering and surface characteristics of coating film on lumbers coated with Hwangchil(varnish of Dendropanax morbiftra), we carried out to investigate the resistance against discoloration, value of crack and surface characteristics of coating films on seven domestic lumbers and those of four introduced tropical lumbers. There was investigated to evaluate the properties of coating films by the varnish of Dendropanax morbifera. There was insignificant correlations between the hardness and moisture contents of each lumber treated by the varnish. There was no significant correlations between the thickness of coating film and the hardness, either. Although we investigated 11 wood species, we found only three species as resistance wood species against discoloration; Diospysos spp., Abies holophylla and Ulmus davidiana. The crack of cooing films was the largest on Zelkova serrata followed by Juglans sinensis, Cercidiphum japonicum, Teetona grands, Ulmus davidiana, Guibourtia tessmannii, Diospysos spp. and Dalbergia latifolia. However, there was no crack of coating films on the lumbers of Juniperus rigida, Prunus serrulata var. spontanea and Abies holophylla. The crack of coating film showed positive correlations with the thickness of coating film and hardness. The surface characteristics of the coating films evaluated on the basis of R;. values indicated the lumbers of Ulmus davidiana(O.l4μm), Juniperus rigida(O.15μm), Guibourtia tessmannii(O.l9μm), Dalvergia latifolia(O.20μm) and Diospysos spp.(O.20μm), Cercidiphum japonieum(O.24μm) as good species while there was insignificant differences between softwoods and hardwoods. Teetona grands, Prunus serrulata var. spontanea and Abies holophylla showed rough surface with 1.53 - 2.63 /lm of R;. values. The four kinds of rough indices(R Rz, R.n.x and Rq) showed very low correlations with moisture contents with the correlation coefficients. The R;. and R.n.x also showed slight relationship with hardness.
