Abstract

This study was carried out to determine the effect of acid rain on the hardness of varnishes used on wooden materials in outdoor weather conditions. For this purpose, sessile oak (Qııercııs petrae Liebl) and Scots pine (Pinus Sylevestrıs L.) woods, which are frequently used, were chosen as test materials. After the samples were covered with synthetic and water-based varnish according to ASTM-D-3023 principles, they were exposed to the effects of sulfuric and nitric acid solutions at different concentrations and different amounts in the test samples, surface hardness according to ASTM-D 4366 principles. According to the experimental results, the highest hardness resistance in terms of material type was determined as oak, synthetic varnish, 5% Na, 120 (I), and the lowest was determined as Scots pine, water-based varnish, 5% Sa, 150 (II). According to the binary interaction, it is highest in Sc+Sn, M+III, Sn+I, M+5N, Sn+5N, II+3N, and lowest in Sc+Sb, Sc+II, Sb+II, Sc+5S, Sb+3S was detected in II+5S. According to the trible interaction, it is highest in Sc+Sn+I, Sc+Sn+3N, M+II+5N, Sn+I+5N, and lowest in Sc+Sb+II, Sc+Sb+3S, Sc+II+. 5N was found in Sb+II+3S. In multiple interaction, the highest hardness value was obtained as Sç+Sn+I+3S (37.6) and the lowest was obtained as Sç+Sb+I+3S (10.0). Accordingly, taking into account the values found in this study in wooden materials such as wooden yachts, garden furniture, wooden bridges, wooden houses, benches, walking paths etc. may be beneficial in terms of their effects on varnish hardness.

Özet

Bu çalışma, dış hava şartlarında bulunan ağaç malzemelerde kullanılan verniklerin sertliğine asit yağmurlarının etkisini belirlemek amacıyla yapılmıştır. Bu maksatla çok sık kullanılan sapsız meşe (Qııercııs petrae Liebl) ve sarıçam (Pinus Sylvetsris L.) odunları deney materyali olarak seçilmiştir. Örnekler, ASTM-D-3023 esaslarına göre sentetik ve su bazlı vernik ile kaplandıktan sonra yüzeyler farklı konsantrasyon ve farklı miktarlarda sülfürik ve nitrik asit çözeltisi etkilerine maruz bırakılmıştır. Deney örneklerinde yüzey sertliği ASTM-D 4366’ya göre belirlenmiştir. Deney sonuçlarına göre, sertlik direnci malzeme çeşidi bakımından en yüksek, meşe, sentetik vernik, %5 Na, 120 (I)’de, en düşük sarıçam, su bazlı vernik, %5 Sa, 150 (II)’de tespit edilmiştir. İkili etkileşime göre en yüksek, Sç+Sn, M+III, Sn+I, M+5N, Sn+5N, II+3N’de, en düşük Sç+Sb, Sç+II, Sb+II, Sç+5S, Sb+3S, II+5S’de tespit edilmiştir. Üçlü etkileşime göre en yüksek, Sç+Sn+I, Sç+Sn+3N, M+II+5N, Sn+I+5N’de, en düşük Sç+Sb+II, Sç+Sb+3S, Sç+II+5N, Sb+II+3S’de bulunmuştur. Sertlik değeri çoklu etkileşimde en yüksek Sç+Sn+I+3S (37,6) en düşük ise Sç+Sb+I+3S (10,0) elde edilmiştir. Buna göre, ahşap yat, bahçe mobilyaları, ahşap köprü, ahşap ev, bank, yürüyüş yolları vb ahşap malzemelerde bu çalışmada bulunan değerlerin dikkate alınması vernik sertliğine etkileri bakımından yarar sağlayabilir.
