Abstract

In this study, polyester based composite material reinforced with additive prepared from waste eggshell was produced. The waste eggshells were supplied from a local catering company, cleaned, dried and ground and then sieved. Egg shell reinforcement ratio (12.5; 10.0; 7.5; 5.0; 2.5% by volume), particle size (θ>0.500μ, 0.500μ>θ>0.250μ, 0.250μ>θ>0.125μ, 0.125μ>θ>0.090μ, 0.090μ>θ) and calcination temperature (800 °C, 900 °C and 1000 °C) were tested. For this purpose, three-point bending, hardness, water absorption, porosity tests were applied to the composite material and finally microstructure analysis was carried out with SEM application. XRD analysis revealed changes in the crystal structure of the eggshell after calcination. The addition of 12.5% ​​eggshell in the composite mixture with particle size less than 90μ gave the best physical and mechanical properties. Increasing of calcination temperature has adversely affected many physical and mechanical properties. According to the test results, it was determined that the eggshell would be suitable for the production of composite materials.

Özet

Bu çalışmada, atık yumurta kabuğundan hazırlanan katkı ile güçlendirilmiş polyester esaslı kompozit malzeme üretilmiştir. Atık yumurta kabukları yerel bir Catering firmasından alınarak temizlenip, kurutulup öğütülmüş ve ardından elenmiştir. Polyestere farklı oranlarda yumurta kabuğu takviye oranı (12,5; 10,0; 7,5; 5,0; 2,5 %hacimce), partikül boyutu (θ>0,500μ, 0,500μ>θ>0,250μ, 0,250μ>θ>0,125μ, 0,125μ>θ>0,090μ, 0,090μ>θ) ve kalsinasyon sıcaklığı (800°C, 900°C ve 1000°C) uygulamalarının etkisi denenmiştir. Bu amaçla kompozit malzemeye üç nokta eğme, sertlik, su emme, porozite gibi testler uygulanmış ve son olarak SEM uygulamasıyla kompozitlere mikro yapı analizi yapılmıştır. Partikül boyutu θ< 90μ’dan küçük ve kompozit karışımında %12,5 oranında yumurta kabuğu katılması en iyi fiziksel ve mekanik özellikleri vermiştir. Kalsinasyon uygulamasında kalsinasyon sıcaklık artışı birçok fiziksel ve mekanik özelliği olumsuz etkilemiştir. Elde edilen test sonuçlarına göre yumurta kabuğunun kompozit malzeme üretiminde kullanımının uygun olacağı belirlenmiştir.
