Abstract

Mobilya, dekorasyon, yapı malzemeleri, aydınlatma gibi birçok sektörde kullanılan POLİCAM PMMA (polimetilmetakrilat) ve polikarbonat (PC) levhalar optik özelliklere sahiptir. Maksimum kullanım sıcaklığı 80°C olan termoplastik polimer levhadır. Amorf yapıya sahip termoplastik polimer oldukça şeffaf ve cama en yakın geçirgenliğe sahiptir. Yoğunluğu camın yoğunluğunun yarısıdır ve hafiftir. Fabrikasyon uygulamaları çok kolaydır. Cam yerine tercih edilir. Maruz kaldığı ortamlarda kullanım alanlarında yüzey çizikleri görülür. Fonksiyonel kaplamalar ile yüzey iyileştirme uygulamaları yapılabilmektedir. Sol-jel yöntemi seramik, cam ve plastik yüzeylerin fonksiyonel kaplanmasında kolay ve kullanışlı olması nedeniyle en yaygın kullanılan yöntemlerden biridir. Bu çalışmada, PMMA  ve PC plaka yüzeylerinin kaplanması için sol jel yöntemi tercih edilmiştir. Hazırlanan fonksiyonel kaplama, bir aplikatör vasıtasıyla PMMA sac yüzeyine belirli kalınlıklarda uygulanır. Kaplama kürlendikten sonra plaka yüzeyinde görülen iyileştirmeler kontrol edilmiştir. SEM ile yüzey taraması, kalem sertlik testi ile yüzeyin çizilmemesi ve yüzeyde kalıcı özellikler suni yaşlandırma ile belirlendi.

Abstract

POLICAM PMMA (polymethylmethacrylate) and polycarbonates (PC) sheet used in many sectors such as furniture, decoration, building materials, lighting have optical properties. They are  thermoplastic polymer sheets with a maximum usage temperature of 80 ° C. Thermoplastic polymer with amorphous structure is quite transparent and has the closest permeability to glass. Its density is half the density of glass and it is light. Fabrication applications are very easy. It is preferred instead of glass. Surface scratches are seen in areas of use in the environments where it is exposed. Surface improvement applications can be made with functional coatings. Sol-gel method is one of the most widely used methods because it is easy and useful in functional coating of ceramic, glass and plastic surfaces. In this study, the sol gel method was preferred for coating PMMA and PC plate surfaces. The prepared functional coating is applied to PC and PMMA sheet surface in certain thicknesses by means of an applicator. The improvements seen on the plate surface after the coating has cured have been controlled. Surface scanning with SEM, anti-scratching of the surface with pencil hardness test, and permanent properties on the surface were determined by artificial aging.
