Investigation of The Effects of Heat Treatment On Varnished Wood Material

Abstract

In this study, the effects of the heat treatment applied varnished wood materials on hardness, brightness and varnishes’ surface sticking resistance were investigated. For this purpose, firstly Pinus Sylvestris L., Fagus Orientalis L. and Castanea Sativa M. wooden samples were varnished by the water based varnish and after that they were kept in temperatures of 100 ˚C, 125 ˚C and 150 ˚C for times of 2, 4 and 6 hours. According to test results it was determined that while the hardness and varnishes’ surface sticking resistance were improved for all samples which were processed 2 hours in temperatures of 100 ˚C, the brightness, surface sticking resistance and brightness of the samples which were processed 4 and 6 hours in 100 ˚C and 2, 4 and 6 hours in 125 ˚C and 150 ˚C were deteriorated. Furthermore, it was observed that the hardness resistance of all samples which processed for 2, 4 and 6 hours in 100 ˚C, 125 ˚C and 150 ˚C were high. In all varnished wood species, the dual-component varnish gave better results than the single-component varnish.
