Bu çalışmanın
amacı ceviz kaplama levhalar üzerine uygulanan sıcaklık ve basınç miktarının
yüzey kalitesi üzerine etkisini belirlemek olacaktır. Ceviz kaplama levhalara 3
dakika süre ile 190 oC ve 210 oC sıcaklıklarda 5000,
10000 ve 15000 pound basınç uygulanmış ve yüzey kalitesindeki değişimler
belirlenmiştir. Levhaların yüzey pürüzlülüğü testleri ISO 4287’ ye göre
ölçülmüştür. Test örneklerinin ortalama pürüzlülük (Ra), on nokta pürüzlülük
ortalama değeri (Rz) ve en büyük pürüzlülük değeri (Rmax) Marsurf M300 cihazı
ile iğne taramalı yöntem ile ölçülmüştür. Uygulanan basıncın ve sıcaklığın
artması ile ceviz kaplama levhalarının yüzey pürüzlülüğünün geliştiği
bulunmuştur. Yüzey kalitesinin en iyi elde edildiği sonuçlar 210 oC
ve 15000 pound basınç uygulanan test numunelerinde belirlenmiştir. Kaplama
levhaların yüzeylerinin sıkıştırılması yüzey kalitesini olumlu etkilemiştir.
