Günümüzde cam kaplamalar sektörde geniş bir yelpazeye sahip ve önemli bir araştırma konusu olmuştur. Özellikle günlük hayatta camın dekoratif obje olarak kullanılması tercih edilmektedir. Bu çalışmada üleksit kullanılarak dekoratif cam kaplama geliştirilmeye çalışılmıştır. Üleksit minerali, beyaz yuvarlak kristal kütlelerden oluşan bir mineraldir. Test sonuçları (görsel, hidrofobiklik, yapışma testleri vb.) dekoratif cam kaplama üretiminde üleksitin katkı maddeleri (potasyum dikromat ve yüzey aktif madde) ile kullanımının kaplama özelliklerini olumlu yönde etkilediğini göstermiştir. Deneysel çalışmada, optimizasyon yöntemi olarak Taguchi Yöntemi kullanılmış ve optimum süreç parametrelerini belirlemek için maliyet ve kaliteyi iyileştirmek için sonuçlar analiz edilmiştir. Hazırlanan kaplamaların termal özelliklerini ve fiziksel morfolojik özelliklerini karakterize etmek için TG-DTA (Termal Gravimetrik Diferansiyel Termal Analiz) ve SEM (Taramalı Elektron Mikroskobu) yöntemleri kullanıldı. Hazırlanan kaplamalara eklenen katkı maddelerinin kaplamanın yapısına olumsuz bir etkisi olmadığı görülmüştür. Sonuç olarak, kullanılan katkı maddeleri cam kaplamaların özelliklerini iyileştirmiş ve sonuçlar çeşitli endüstrilerde hazırlanan katkı kaplamalarının değerlendirilebileceğini göstermiştir.

Optimization and Enhancement of Decorative Glass Organic Coating Properties Containing Ulexite Mineral

Öz

Today, glass coatings have a wide range in the industry and have been an important research topic. It is preferred to use glass as a decorative object especially in daily life. In this study, decorative glass coating was tried to be developed with the use of ulexite. The ulexite mineral is a mineral consisting of white round crystalline masses. Test results (visual, hydrophobicity, adhesion tests, etc.) showed that the use of ulexite with additives (potassium dichromate and surfactant) positively affects the coating properties in decorative glass coating production. In the experimental study, Taguchi Method was used as an optimization method and the results were analyzed to improve cost and quality to determine the optimum process parameters. TG-DTA (Thermal Gravimetric Differential Thermal Analysis) and SEM (Scanning Electron Microscope) methods were used to characterize the thermal properties and physical morphological properties of the coatings prepared. It was observed that the additives added in the coatings prepared did not have a negative effect on the structure of the coating. As a result, the additives used improved the properties of glass coatings and the results showed that additive coatings prepared in various industries can be evaluated.
