Abstract

Çalışmanın amacı: Isıl işlem (ThermoWood) görmüş bazı ağaç türlerinde
kullanılan su bazlı vernik katmanlarının hızlandırılmış UV yaşlandırma etkisine
karşı renk değişim özelliklerini belirlemektir.

Çalışma alanı: Isıl işlem görmüş, su bazlı vernik, yaşlandırma ve
renk arasındaki ilişkinin belirlenmesidir.

Materyal
ve Yöntem:
Bu amaç ile Sarıçam
(Pinus sylvestris L.), Sapsız meşe (Quercus petreae L.) ve Doğu kayını (Fagus orientalis L.) odunlarından
hazırlanan deney örnekleri ThermoWood metoduna göre 190oC’de 2 saat,
212oC’de 1 saat ve 2 saat süreler ile ısıl işleme tabi tutulmuştur.
Daha sonra deney örneklerinin yüzeylerine, tek ve çift bileşenli su bazlı
vernikler üretici firmaların önerilerine göre uygulanmış ve UV-A 340 nm
florasan lambalarının bulunduğu “QUV accelerated weathering tester” cihazında;
144, 288 ve 432 saat süre boyunca UV etkisine altında (ASTM G 154-06, 2006) yaşlandırmaya maruz bırakılmışlardır.
Yaşlandırma sonrasında, kırmızı renk tonu, sarı renk tonu, ışıklılık ve toplam
renk farkı değerleri ASTM-D 2244-3 standardına göre belirlenmiştir.

Sonuçlar:
Yaşlandırma sonrasında ışıklılık ve toplam renk farkı
değerlerinin artış gösterdiği belirlenmiştir.









Araştırma vurguları: Yaşlandırmaya
bağlı olarak bütün renk parametreleri değişmiştir.

Determination of the color changes against accelerated UV aging of used water based layers on some heat-treated (ThermoWood) wood species

Abstract

Aim of study: The
objective of this study is to investigate the accelerated UV resistance of
water-based varnish layers, applied on heat-treated wood (ThermoWood) surfaces.

Area of study: Determination
of the relationship between heat-treated, water based varnish, aging and color.

Material
and Methods:
Wood specimens prepared from Scotch
pine (Pinus sylvestris L.), Oak (Quercus petreae L.) and Oriental beech (Fagus orientalis L.) were heat-treated
according to ThermoWood method at 190oC for 2 hours, and at 212oC
for 1 hour and 2 hours. Following the heat treatment, one and two component
water-based varnishes were applied to similar layer thicknesses. The finished
specimens were exposed to UV-A 340 nm fluorescent lamp in a “QUV accelerated
weathering tester” for 144, 288 and 432 hours (ASTM G 154-06, 2006). At the end
of each exposure period, red color tone, yellow color tone, lightness and total
color difference values were determined according to ASTM-D 2244-3.

Main results: Lightness
and total color difference values of the water-based single and double
component varnishes increased after the UV aging.









Research highlights: All
color parameters had changed due to aging.
