Abstract

Bu çalışmada, imin bağı içeren inorganik ve organik bileşiklerin 190 °C sıcalıkta sert PVC üretiminde termal stabilizatör olarak kullanılabilirliği incelenmiştir. Termogravimetrik analiz sonuçlarında inorganik bileşiklerin organik bileşiklere göre termal kararlılıklarında artış olduğu gözlenmiştir. Sentezlenen inorganik ve organik bileşiklerin baz stabilizatörü ile farklı oranlarda karıştırılması sonucunda, piyasada kullanılan referans stabilizatöre göre plastikleşme torku ve süresi ile termal dayanım süreleri kıyaslanmıştır. Bileşiklerin yüksek termal kararlılığa sahip olmasından dolayı endüstride kullanılan referans termal stabilizatöre oranla daha uzun sürede bozunmaya uğramasından dolayı tercih edilebileceği düşünülmektedir.

Investigation of Usability of Imine Bonded Inorganic and Organic Compounds as Thermal Stabilizers for Unplasticized Poly(vinyl chloride)

Abstract

In this study, the usability of inorganic and organic compounds containing imine bonds as thermal stabilizers in rigid PVC production at 190 °C were investigated. In the results of thermogravimetric analysis, it was observed that the thermal stability of inorganic compounds increased compared to organic compounds. As a result of mixing the synthesized inorganic and organic compounds with the base stabilizer at different rates, the plasticization torque and time and thermal endurance times were compared with the reference stabilizer used in the market. Due to the high thermal stability of the compounds, it is thought that it can be preferred because it degrades in a longer time than the reference thermal stabilizer used in the industry.
