While most efforts are aimed at preventing the surface roughening and colour change of wood due to weathering, some, mainly for decorative reasons, want wooden objects and elements to give the impression that they have been weathered for a long time. In this study, the simulated weathering of numerous softwoods as well as ring-porous and diffuse-porous woods by sandblasting and greying with iron sulphate was investigated. Calculations of the correlations between wood density, orientation, mass loss and thickness reduction by sandblasting, the difference between the hardness of late and early wood and the surface profile parameter Pt showed that the surface profiles correlates strongly with the mass loss, especially in the tangential orientation. Softwoods appeared to be the most promising for simulated profiling, especially spruce and larch with tangential surfaces. Among the ring-porous woods, oak and sweet chestnut also delivered good results.

Abstract

Medtem ko je večina prizadevanj usmerjena v preprečevanje hrapavosti površine in spremembe barve lesa zaradi delovanja vremenskih vplivov, nekateri želijo, predvsem iz dekorativnih razlogov, da leseni predmeti in elementi dajejo vtis, da so bili dolgo izpostavljeni staranju zaradi izpostavitve na prostem. V tej študiji smo preučevali simulirano vremensko staranje številnih vrst lesa iglavcev ter venčasto poroznih in difuzno poroznih listavcev s peskanjem in sivenjem z raztopino železovega sulfata. Izračuni korelacij med gostoto lesa, orientacijo, izgubo mase in zmanjšanjem debeline zaradi peskanja, ter razliko med trdoto kasnega in ranega lesa, in parametrom površinskega profila Pt, so pokazali, da je površinski profil močno koreliran z izgubo mase, zlasti v tangencialni orientaciji. Les iglavcev se je izkazal za najbolj obetavnega za simulirano profiliranje, zlasti tangencialne površine smrekovine in macesenovine. Med venčasto poroznimi vrstami lesa sta dobre rezultate pokazala tudi hrastovina in les domačega kostanja.
