Özet:

This study was carried out to determine the effects of soaking in water at different degrees and times on the amount of change in size in the tangential direction of some impregnated and varnished wood materials. For this purpose, samples prepared from sessile oak (Quercus petraea L.) and Anatolian walnut (Juglans regia L.) were impregnated with styrene by dipping method according to ASTM-D 1413-99 for 24 hours and then varnished with cellulosic varnish according to ASTM D-3023. with varnish. After the prepared samples were kept in distilled water for different times (2 and 8 hours) and temperatures (20±2 and 40±5 °C degrees), the size changes in the tangential directions were measured with a digital caliper with a sensitivity of 0.01 according to ISO 13061-15 principles. As a result, the tangential dimension change (mm) was highest in oak (20.25), in eight hours of soaking (20.21), water temperature at 40±5 °C (20.15), impregnation (20.58) , the lowest walnut (20.08) was kept in water for two hours (19.98), the temperature was 20±2 °C (20.05), impregnated and varnished samples (20.29). In terms of multiple interactions, the highest M+S8+II+E was found (21.53) and the lowest was found in M+S2+II+Vk (19.55). As a result, in the amount of tangential size change of oak and walnut wood to be used in the construction of sinks and bathtubs; It can be said that the first degree of residence time, the second degree water temperature, the third degree type of treatment, and the fourth degree tree species are effective. Considering these results in the construction of wooden sinks and bathtubs can provide an advantage in the dimensional stability of the products.
