Abstract

Aim of
study: Investigation
of some mechanical properties of panels produced using polyethylene waste as
adhesive instead of formaldehyde-based resins used in plywood was aimed and
polyethylene amount was tried
to determine for plywood produced from different wood species.

Area of study: This study was conducted at
the Pilot Facility of Department of Forest Industry Engineering, Karadeniz
Technical University in Trabzon, Turkey.

Material
and Methods: Beech (Fagus
Orientalis Lipsky), alder (Alnus
glutinosa subsp. barbata) and
Scots pine (Pinus sylvestris L.) veneers were used to produce
polyethylene plywood. Three different polyethylene amounts was used (160, 200
and 240 gr/m²). Density, shear strength, bending strength and
modulus of elasticity of plywood panels were determined according to TS EN
323-1, TS EN 314-1 and TS EN 310, respectively.

Main
results: The
best mechanical strength values for beech and alder were obtained from panels
produced using 200 gr/m² polyethylene amounts. Moreover, these
values for Scots pine were found in panels produced using 160 gr/m² polyethylene
amounts.

Research
highlights: When this study applies in the plywood industry,
can provide to both recycle polyethylene waste and prevent formaldehyde
release. Polyethylene plywood waste can be used production of wood plastic
composite panels.

Özet

Çalışmanın
amacı: Kontrplak sektöründe kullanılan
formaldehit esaslı reçineler yerine bağlayıcı olarak atık polietilen
kullanılmasıyla üretilmiş levhaların bazı mekanik özelliklerinin araştırılması
amaçlanmış ve farklı ağaç türlerinden üretilmiş levhalar için optimum
polietilen miktarları belirlenmeye çalışılmıştır.

Çalışma alanı: Bu çalışma, Trabzon’daki Karadeniz Teknik
Üniversitesi Orman Endüstri Mühendisliği Bölümü Pilot tesisinde yapılmıştır.

Materyal
ve Yöntem: Kayın (Fagus Orientalis Lipsky), kızılağaç (Alnus glutinosa subsp. barbata)
ve sarıçam (Pinus sylvestris L.)
kaplamalar, polietilen kontrplakların üretiminde
kullanılmıştır. Üç farklı polietilen miktarı seçilmiştir (160, 200 ve 240 gr/m²).
Üretilen levhaların y TS EN 323-1,  çekme
makaslama direnci TS EN 314-1, eğilme direnci ve elastikiyet modülü ise TS EN
310 standartlarına göre belirlenmiştir.

Sonuçlar: En iyi mekanik direnç değerleri, kayın ve kızılağaç
için 200 gr/m² polietilen miktarı kullanılarak üretilen levhalardan
elde edilmiştir. Ayrıca, sarıçam için en iyi değerler ise, 160 gr/m²
polietilen miktarı kullanılarak üretilen levhalarda bulunmuştur.

Araştırma
vurguları: Bu
çalışma, kontrplak endüstrisinde uygulanmasıyla birlikte hem polietilen
atıkların geri dönüşümü sağlanabilir, hem de levhalardaki formaldehit salınımı
önlenebilir. Polietilen ile üretilen kontrplakların atıkları, ahşap plastik
kompozit panellerin üretiminde de kullanılabilir.
