Yüksek Yoğunluklu Polietilen (HDPE)/Pinna Nobilis Polimer Karışımının Özelliklerinin İncelenmesi

Abstract

Bu çalışmada yüksek yoğunluklu polietilen içerisine %10-20-30 ve 40 oranlarında istiridye veya midye gibi kabuklu bir deniz ürünü olan pinna nobilis ilave edilerek ekstürüzyonda karışımları yapılmış ve bir polimer kompoziti elde edilmiştir. Elde edilen polimer kompozitlerinden enjeksiyon makinesinde standartlara uygun olarak çeşitli test numuneleri basılmıştır. UL 94, oksijen indeksi ve kızgın tel deneyleri yapılarak polimer kompozitinin yanma davranışları belirlenmiştir. Ayrıca elastiklik modülü, akma mukavemeti, kopma mukavemeti, % uzama değeri, Izod darbe mukavemet değeri, sertlik ve yoğunluk değerlerinin pinna nobilis oranının artmasıyla nasıl değiştiği rapor edilmiştir. Bunlara ek olarak taramalı elektron mikroskobisi ile kırık yüzey fotoğrafları çekilerek polietilen ile pinna nobilis partiküllerinin yapışması ve dağılımları belirlenmiştir.

Investigation of Properties of High Density Polyethylene (HDPE)/Pinna Nobilis Polymer Composites

Abstract

In this study, pinna nobilis, a shellfish such as oyster or mussel, was added into high density polyethylene in the ratio of 10-20-30 and 40%, and blends were made in extrusion and a polymer composite was obtained. Various test samples were molded from the obtained polymer composites in accordance with the standards in the injection molding machine. The burning behavior of the polymer composite was determined by conducting UL 94, limit oxygen index and glow wire tests. In addition, it has been reported how elastic modulus, yield strength, tensile strength, % elongation value, Izod impact strength value, hardness and density values change with the increase of pinna nobilis ratio. In addition to these, the adhesion and distribution of polyethylene and pinna nobilis particles were determined by taking fracture surface photographs with scanning electron microscopy.
