Abstract

Çalışmanın
amacı:
Ahşap kompozit malzemelerin üretiminde
kullanılan tutkalların birçoğu formaldehit içeriği nedeniyle insan ve çevre
sağlığı açısından bir tehdit unsuru olarak görülmektedir. Bu nedenle odun
kökenli levhalarda ki formaldehit emisyonunun azaltılmasına yönelik etkili
metotların geliştirilmesi için birçok çalışma yapılmış ve çeşitli yöntemler
denenmiştir. Bu çalışmada polistren kompozit kontrplakların bazı teknolojik
özellikleri üzerine pres parametrelerinin etkilerinin araştırılması
amaçlanmıştır.

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

Materyal
ve Yöntem:
Polistren kompozit kontrplakların
üretiminde kavak (Populus deltoides)  kaplamalar kullanılmıştır. Geleneksel
kontrplakların üretiminde yapıştırıcı olarak ÜF tutkalı kullanılmıştır.
Polistren kompozit kontrplakların üretiminde farklı pres sıcaklıkları (130,
140, 150 oC) ve pres süreleri (6, 8, 10 dakika)
seçilmiştir. Levhaların,  çekme makaslama
direnci TS EN 314-1, eğilme direnci ve elastikiyet modülü TS EN 310, özgül
ağırlıkları TS EN 323 ve denge rutubet miktarları TS EN 322 standartlarına göre
belirlenmiştir.

Sonuçlar: Yapılan deneyler sonucunda genel olarak levhaların
mekanik özelliklerinin ve yoğunluk değerlerinin pres sıcaklığı ve pres
süresinin artmasına bağlı olarak artış gösterdiği görülürken denge rutubet
miktarlarının azaldığı görülmüştür.









Araştırma
vurguları:
Bu çalışma,
polistiren atıklarının kontrplak üretiminde iç mekan kullanımları için
alternatif bir yapıştırma malzemesi olarak kullanılabileceğini ortaya
koymuştur.

Abstract

Abstract

Aim of study: Formaldehyde
content of most of resins used in wood based composite production, wood
composite materials have been seen a threat on human health and environment.
Therefore, numerous studies have been made to develop an effective method to
decrease formaldehyde emission from the wood based panels and various methods
have been tried. The aim of the study was to investigate those effects of press
parameters on some technological properties of polystren composite plywood.

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: Poplar
(Populus deltoides) veneers were used
to produce polystren composite plywood. Urea-formaldehyde adhesive was used as
bonding material for traditional plywood panels. Three different press
temperature (130, 140, 150 oC) and pressing time (6, 8, 10 minutes)
were chosen as press parameters in the manufacturing of polystren composite
plywood. Bonding strength, bending strength, modulus of elasticity, density and
equilibrium moisture content of panels were determined according to TS EN
314-1, TS EN 310, TS EN 323 and TS EN 322, respectively.

Main results: The
experimental results showed that mechanical properties and density of panels
generally increased with increasing press temperature and pressing time whereas
the equilibrium moisture content of panels decreased.











Research highlights: This study
showed that polystyrene wastes can be used in plywood manufacturing as an
alternative bonding material for interior uses.
