Bu
çalışmada, büyük oranda selüloz lifler ile inorganik katkılar (kalsit ve kil
mineralleri) içeren kağıt üretim atıkları, farklı oranlarda (ağırlıkça %10-60)
yüksek yoğunluklu polietilen (YYPE) kompozit üretiminde kullanılarak kağıt
üretim atığı katkısının mekanik özellikler üzerindeki etkisi incelenmiştir.
Kompozitler yüksek hızlı termo-kinetik mikseri ve kalıplama prosesi
kullanılarak üretilmiştir. Üretilen kompozitlerin mekanik özellikleri standart
test metotları kullanılarak analiz edilmiştir. Sonuçlara göre, kompozitlerin
eğilme modül değerlerinin artan katkı oranıyla arttığı görülmüştür. Özellikle,
eğilme dayanımının ağırlıkça %40 katkı içeren kompozitte %26.3 oranında arttığı
ortaya konmuştur. Kağıt atık katkılı YYPE kompozitlerin çekme dayanımı YYPE
matris ile kıyaslandığında %10-20 oranında artış görülmüştür. Sonuç olarak, sunulan çalışmada kağıt üretim
atık katkıları hiçbir modifikasyon ajanı kullanılmadan kompozitlerin üretimi
gerçekleştirilmiş ve buna rağmen kompozitlerin mekanik özelliklerinde gelişme
sağlanmıştır. Bu sayede, endüstriyel atık olarak ekonomik bir değeri olmayan
kağıt üretim atığı polimer kompozit yapı içerisinde kullanılarak iyi mekanik
özelliklere sahip kompozitler üretilmiştir.

Investigation of mechanical properties of paper processing residue filled high density polyethylene (hdpe) composites

Öz

In
this study, paper processing residues containing a large extent cellulosic
fibrous with inorganic filler such as calcite and clay minerals were used in
the manufacturing of high density polyethylene (HDPE) composite. The residues
ranging from 10 to 60wt% were loaded into HDPE in order to evaluate the effect
of the paper processing residue filler on mechanical properties of HDPE. The
composites were produced using mixing process by a high-speed thermo-kinetic
mixer and molding process. Mechanical properties of the produced composites
were analyzed using standard test methods. According to results, it was
observed that the flexural modulus of composites increased with increasing
filler contents. Especially, the flexural strength was increased by 26.3% for
the 40wt% filler content. The tensile strength of paper industry mill residues
filled HDPE composites exhibited an increase of 10-20% compared to that of HDPE
matrix. Consequently, in the present study, paper processing residues filler
without any modifying agent was used for the production of HDPE composites
having better mechanical properties compared to HDPE. Thus, paper processing
residues which have no economic value and cause an environmental problem have
served as a filler material for HDPE.
