Kömür küllerinin geri dönüşümü olmadığı için doğaya atılması ciddi zararlar ortaya çıkarmaktadır. Aynı zamanda kömür külünün kimyasal bileşiminde insan ve hayvan sağlığına zararlı maddelerin olması özellikle doğal yağışlar sayesinde içme sularına karışması canlıların ve sulama yapılan tarım alanlarını ciddi şekilde tehlikeye sokmaktadır. Türkiye’de birçok termik santral bulunmaktadır. Buralardan elde edilen atıkların geri dönüştürülmesi ve ekonomiye kazandırılması büyük önem arz etmektedir. Endüstriyel atıkların polimer teknolojisi sektöründe dolgu olarak kullanılmasıyla ilgili sınırlı sayıda çalışmalar mevcuttur. Kömür külünün polimer matrisli bileşiklerde kullanılması ile ilgili hiçbir çalışma mevcut değildir. Bu çalışmada SBR matrisine %0, %5, %10 ve %15 oranında karbon siyahına ek olarak kömür külü ilave edilmiş ve 4 farklı bileşik elde dilmiştir. Elde edilen bu bileşiklerin çapraz bağ yoğunluğu hesaplanmış ve çapraz bağ yoğunluğunun mekanik özellikler üzerine etkisi araştırılmıştır. Bileşiklerdeki kömür külü dolgu oranı yükseldikçe, bileşiklerin çapraz bağ yoğunluğunun artmasına ve buna bağlı olarak, sertlik, yüzde uzama, kopma mukavemeti gibi mekanik özellikleri geliştirdiği ve özgül ağırlık gibi fiziksel özelikleri de arttırdığı görülmüştür.

Effect on Mechanical Properties of Addition of Coal Ash as Thermal Power Plant Waste to SBR Matrix Compounds

Öz

The disposal of coal ashes into the environment due to their non-recyclable nature poses significant harms. Moreover, the presence of harmful substances in the chemical composition of coal ash, coupled with the potential contamination of drinking water sources and irrigation areas through natural precipitation, poses serious threats to both living organisms and agricultural lands. There are many thermal power plants in Turkey. It is of great importance that the wastes obtained from these areas are recycled and brought into the economy. There are limited studies on the use of industrial wastes as filler in the polymer technology sector. There are no studies on the use of coal ash in polymer matrix compounds. In this study, 0%, 5%, 10%and 15%carbon black were added to the SBR matrix in addition to coal ash and 4 different compounds were obtained. The crosslink density of these obtained compounds was calculated and the effect of crosslink density on mechanical properties was investigated. It was observed that as the coal ash filling ratio in the compounds increased, the crosslink density of the compounds increased and accordingly, mechanical properties such as hardness, percent elongation, breaking strength and physical properties such as specific gravity increased.
