Investigation of Mechanical, Tribological and Microstructural Properties of Seaweed (Ecklonia Maxima) Added Polypropylene Composite

Öz

In this study, polymer biocomposites were produced by adding seaweed powders (ecklonia maxima) in different proportions into polypropylene. Therefore, the changes in some mechanical and physical properties of seaweed powders with the addition of polypropylene were investigated. Seaweed powders were added to polypropylene at the rates of 10, 20 and 30%, mixed in a twin screw extruder and produced as granules. In addition, maleic anhydride grafted polypropylene (MAPP) at the rates of 5% was added to the biocomposite as a compatibilizer and its effect was investigated. The granules obtained in the extruder were dried and the test samples were moulded in the injection machine in accordance with the standards. Density, water absorption rate, wear rate, static-dynamic friction coefficient and morphological structure of the obtained biopolymer composite were investigated. According to the results obtained, with the increase in seaweed addition, a decrease in density and friction coefficient values was detected, while an increase in water absorption rate and wear rate values was detected. From the microstructure photographs taken, it was determined that there was adhesion with the addition of maleic anhydride.

Deniz Yosunu (Ecklonia Maxima) Katkılı Polipropilen Kompozitinin Mekanik, Tribolojik ve Mikroyapısal Özelliklerinin İncelenmesi

Öz

Bu çalışmada, polipropilen içerisine değişik oranlarda deniz yosunu (ecklonia maxima) tozları katılarak biopolimer kompozitleri üretilmiştir. Dolayısıyla deniz yosunu tozlarının polipropilene eklenmesi ile bazı mekanik ve fiziksel özelliklerindeki değişimler incelenmiştir. Yosun tozları polipropilen içerisine % 10, 20 ve 30 oranlarında katılarak çift vidalı ekstruderde karıştırılmış ve granül halinde üretilmiştir. Ayrıca biokompozit içerisine uyumlaştırıcı olarak maleik anhidrit aşılı polipropilen %5 oranında (MAPP) eklenmiş ve etkisi incelenmiştir. Ekstrüzyon makinesinde elde edilen granüller kurutulmuş ve enjeksiyon makinesinde standartlara uygun şekilde test numuneleri basılmıştır. Elde edilen biopolimer kompozitinin yoğunluk, su emme oranı, aşınma oranı, statik-dinamik sürtünme katsayısı ve morfolojik yapısı incelenmiştir. Elde edilen sonuçlara göre yosun ilavesinin artışıyla yoğunluk ve sürtünme katsayısı değerlerinde düşüş buna karşılık su emme oranı ve aşınma oranı değerlerinde ise artış tespit edilmiştir. Çekilen mikroyapı fotoğraflarından maleik anhidrit ilavesi ile adhezyonunun da olduğu belirlenmiştir.
