Effect of Ultrasonic Bath Applied as Pretreatment on the Properties of Walnut Veneers

Öz

The aim of this study is to investigate the effects of ultrasonic bath, which is generally used for surface cleaning, on drying time, surface roughness, color and density of walnut veneers. For this purpose, coating samples prepared in identical sizes were pretreated with an ultrasonic bath set at three different times and temperatures at fixed frequency (40 kHz). After these three different ultrasonic pretreatments applied, the effects of changes in the structure of walnut coatings on drying time, density (g/cm3) values, surface roughness parameters according to ISO 4287 standard and color parameters in accordance with ISO 2469 (2014) standards were examined. According to the results obtained; optimum conditions in which walnut veneer samples will be least affected by ultrasonic washing; It was determined as 15 minutes at 25°C. 

Anahtar Kelimeler

• Ultrasonic bath
• drying time
• density
• surface roughness
• color change.

Ön İşlem Olarak Uygulanan Ultrasonik Banyonun Ceviz Kaplamaların Özellikleri Üzerine Etkileri

Öz

Bu çalışmanın amacı, genellikle yüzey temizliği için kullanılan ultrasonik banyonun ceviz kaplamaların kurutma süresi, yüzey pürüzlülüğü, rengi ve yoğunluğu üzerine olan etkilerinin incelenmesidir. Bu amaçla, özdeş boyutlarda hazırlanan kaplama örnekleri sabit frekansta (40 kHz) üç farklı süre ve sıcaklıkta ayarlı ultrasonik banyo ile ön işleme tabi tutulmuştur. Uygulanan bu üç farklı ultrasonik ön işlem sonrası ceviz kaplamaların yapılarında meydana gelen değişimlerin, kuruma süresine, yoğunluk (g/cm3) değerlerine, ISO 4287 standardına göre yüzey pürüzlülüğü parametrelerine ve ISO 2469 (2014) standartlarına uygun olarak renk parametrelerine olan etkileri incelenmiştir. Elde edilen sonuçlara göre; ceviz kaplama numunelerinin ultrasonik yıkama da en az etkileneceği optimum şartlar; 25°C’de 15 dakika olarak tespit edilmiştir.

Anahtar Kelimeler

• Ultrasonik banyo
• kuruma süresi
• yoğunluk
• yüzey pürüzlülüğü
• renk değişimi.
