Sentetik Reçine Emprenyeli α-Selüloz Dekor Kağıdı Lamine Yonga Levha Yüzeylerinin Görsel ve Kolorimetrik Değerlendirmeleri: Karşı-laştırmalı Bir Çalışma

Öz

Bu çalışma, beyaz dekor kağıdı ile kaplanmış ve α-selüloz bazlı melamin reçine ile emprenye edilmiş yonga levha yüzeylerinin beş farklı yüzey işlem maddesi ile muamele edildikten sonra görsel ve enstrümantal olarak incelenmesini amaçlamaktadır. Üç farklı tür (-A, -B, -C) ve her biri için üç farklı gramajda kaplanmış numuneler TS EN 14323 standardına göre değerlendirilmiş, renk ve doku değişiklikleri karşılaştırılmıştır. Veriler istatistiksel olarak analiz edilerek ANOVA ve Duncan testi kullanılmıştır. En düşük parlaklık değeri (L*: 92.79) 110 g/m² gramajlı B tipi dekor kağıdı ile kaplanmış ve su (Wa) ile aseton (Ac) ile işlenmiş numunelerde tespit edilmiştir. a* renk koordinatı değerleri ihmal edilebilir düzeyde (a*: <1.0) bulunurken, b* koordinatındaki değişimler belirli seviyelerde hesaplanmıştır. En yüksek b* değişimi, aseton ile işlem görmüş 80 g/m² gramajlı A tipi kağıtta (Δb*A80Ac: 0.51, %27.4 fark) gözlenmiştir. En büyük renk değişimi 110 g/m² gramajlı A tipi su buharı ile işlenmiş (ΔEA110Wa: 0.61) ve 80 g/m² gramajlı B tipi kahve ile işlenmiş (ΔEB80Co: 0.68) numunelerde tespit edilmiştir; ancak bu değişimler görsel olarak fark edilemez düzeydedir (ΔEB: <0.70). En yüksek renk farkı, 90 g/m² gramajlı C tipi alkol ile işlem görmüş numunelerde (ΔEC90Al: 1.48) bulunmuş, bunu aseton (ΔEC90Ac: 1.18) ve su (ΔEC90Wa: 0.91) takip etmiştir. Sonuçlar, görsel algı ile kolorimetrik ölçümler arasında genel olarak iyi bir korelasyon olduğunu, ancak bazı marjinal farklılıkların gözden kaçabileceğini göstermektedir. Çalışma, renk ölçüm analizlerinin görsel değerlendirmelere kıyasla daha hassas sonuçlar sunduğunu vurgulamaktadır.

Visual and Colorimetry Assessments of Synthetic Resin Impregnated α -Cellulose Decor Paper Laminated Particleboard Surfaces: A Comparative Study

Abstract

This study aims to visually and instrumentally examine the surfaces of particleboards laminated with white decor paper impregnated with α-cellulose-based melamine resin after treatment with five different surface processing agents. Samples of three different types (-A, -B, -C), each with three different grammages, were evaluated according to the TS EN 14323 standard, and color and texture changes were compared. The data were statistically analyzed using ANOVA and the Duncan test. The lowest brightness value (L*: 92.79) was found in samples laminated with 110 g/m² grammage B-type decor paper and treated with water (Wa) and acetone (Ac). The a* color coordinate values were found to be negligible (a*: <1.0), while variations in the b* coordinate were calculated at certain levels. The highest change in the b* coordinate was observed in the acetone-treated surface of the 80 g/m² grammage A-type decor paper (Δb*A80Ac: 0.51), with a difference of 27.4% compared to the control sample. The most significant color changes were found in the 110 g/m² grammage A-type samples treated with water vapor (ΔEA110Wa: 0.61) and the 80 g/m² grammage B-type samples treated with coffee (ΔEB80Co: 0.68); however, these changes were visually undetectable (ΔEB: <0.70). The highest color difference was observed in 90 g/m² grammage C-type samples treated with alcohol (ΔEC90Al: 1.48), followed by acetone (ΔEC90Ac: 1.18) and water (ΔEC90Wa: 0.91). The results indicate a strong correlation between visual perception and colorimetric measurements; however, some marginal differences may be overlooked. This study emphasizes that colorimetric assessments provide more precise results compared to visual evaluations.
