EVALUATION of TREATMENT SLUDGE, SEPIOLITE and EGG SHELLS in THE PRODUCTION of POLYMER COMPOSITE PLATES

Abstract

The aim of this study is to produce thermoplastic composite plates containing waste materials using additives such as industrial sewage sludge, eggshells and sepiolite, to determine the mechanical properties of these plates and to compare them with commercial polypropylene plates. These fillers were added to the polypropylene (PP) based composite in an amount of 20-50% by weight (dry basis), and all composite plates were prepared using the hot compression molding method. Mechanical properties (tensile strength, tensile modulus of elasticity, flexural strength, elasticity of bending coefficient, elongation and impact strength at break) and radiation permeability of composites were investigated and it was determined that filler type had an effect on mechanical properties significantly. It was found that the addition of egg shells reduced the radiation permeability of the PP-based composites and increased their tensile strength. Addition of sewage sludge to composite production decreased the tensile strength while, it caused to increase elasticity modulus in flexure because of its fibrous structure with sepiolite. In the light of these results, it was determined that PP based polymer composites produced with waste additives provide sufficient mechanical properties than only PP based polymer composite plates.

ARITMA ÇAMURU, LÜLE TAŞI (SEPIYOLIT) VE YUMURTA KABUĞU ATIKLARININ POLİMER KOMPOZİT PLAKA ÜRETİMİNDE DEĞERLENDİRİLMESİ

Öz

Bu çalışmanın amacı, kağıt endüstrisi arıtma çamurunun yine atık materyaller olan yumurta kabuğu ve lületaşı (sepiyolit) tozu ile birlikte polipropilen (PP) bazlı termoplastik plaka üretiminde değerlendirilmesi ve elde edilen termoplastik kompozit plakanın radyasyon geçirgenlik ve mekanik dayanım (eğilme direnci, çekme direnci, dinamik eğilme direnci, kopmada uzama ve darbe direnci) özelliklerinin belirlenmesidir. Atık materyaller kütlece %20-50 oranlarında kompozit levha üretimine katılmış, tüm kompozit plakalar standart sıcak presleme yöntemi ile üretilmiş ve katkı maddeli polimer kompozitlerin özellikleri standart polipropilenden üretilen levha ile karşılaştırılmıştır. Elde edilen sonuçlarda yumurta kabuğu katkılı kompozit levhanın radyasyon geçirgenliğini azalttığı, çekme direncini artırdığı, arıtma çamurunun çekme direncini düşürdüğü ve arıtma çamurunda bulunan liflerin ve lületaşı tozunun elastikiyet modülünü artırdığı tespit edilmiştir. Katkı maddeleri kompoziti daha gevrek hale getirerek kopmada uzama ve eğilme direnci modülü değerlerini azaltmıştır. Eğilmede elastikiyet modülü değerleri ise arıma çamuru ve sepiyolit ilavesi ile artış göstermiştir. Üretilen PP kompozitlerin tamamı ASTM D 6662’de istenilen değerlerden daha yüksek eğilme direnci ve eğilmede elastikiyet modülü değerleri sağlamıştır. Bu çalışmanın sonuçları, günlük atılım miktarları çok yüksek olan arıtma çamuru, yumurta kabuğu ve lüle taşı gibi atık maddelerin “sıfır atık” yaklaşımı ile yeniden değerlendirilmelerinin sağlayarak kompozit levha üretiminde kullanılabileceğini ve ülke ekonomisi açısından faydalı malzeme üretiminin gerçekleştirilebileceğini ortaya koymuştur.
