Abstract

The wettability behavior is crucial in determining the materials' applications and durability. To assess the wettability behavior, the measurement of contact angle is utilized. In this study, commercially produced PVC profiles were sampled, and a contact angle measurement system, consisting of both software and hardware, was developed to measure the contact angle of the samples. The contact angle measurements were conducted by placing approximately 20 µl of distilled water on the samples, and each sample was measured six times, with the average being taken. A device for measuring roughness was used to determine the surface roughness of the samples, and the average roughness value was obtained from four different parts of each sample. Additionally, SEM images of each sample were taken to conduct surface and structural analyses. The correlation between roughness, SEM image analysis results, and contact angle was examined in the research study. Moreover, the wettability behavior of PVC materials was analyzed by evaluating the impact of the elements in their structure and their homogeneity on the contact angle values.

Dış Mekan Uygulamalarında Kullanılan PVC Malzemelerin Islanabilirlik Davranışının ve Yüzey Topolojisinin İncelenmesi

Abstract

Islanabilirlik davranışı malzemelerin kullanım alanlarının ve servis ömrünün belirlenmesinde önemli bir parametredir. Islanabilirlik davranışını belirlemek için temas açısı ölçümü kullanılır. Bu çalışma kapsamında ticari olarak üretilen PVC profillerden numuneler alınmıştır. Numunelerin temas açısı ölçümlerinin yapılabilmesi için yazılım ve donanımdan oluşan temas açısı ölçüm sistemi geliştirilmiştir. Numunelerin üzerine yaklaşık 20 µl distile su damlatılarak temas açısı ölçümleri yapıldı. Her numune için 6 kez temas açısı ölçümü yapılarak ortalaması alındı. Numunelerin yüzey pürüzlülüğü pürüzlülük ölçüm cihazı ile ölçülmüştür. Numunelerin farklı yerlerinden 4 kez pürüzlülük ölçümleri yapılarak ortalama pürüzlülük değeri elde edildi. Ayrıca her bir numunenin SEM görüntüleri alınarak yüzey ve yapısal analizleri yapılmıştır. Sonuç olarak temas açısı, pürüzlülük ve SEM görüntü analiz sonuçları arasındaki ilişki araştırıldı. Ayrıca PVC malzemelerin yapısındaki elementlerin ve homojenlik yapısının temas açısı değerlerine etkisi değerlendirilerek PVC malzemelerin ıslanabilirlik davranışı yorumlanmıştır.
