It is
desired the wood composite materials which have broaden using areas in human
residence have no negative effects on human health and environment. But because
of 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 pressing time
on some technological properties of nylon composite LVL. Poplar (Populus deltoides) veneers were used to
produce nylon composite LVL. Three different pressing time (8, 10, 12 minutes)
and pressing temperature 140 °C were chosen as press parameters in the
manufacturing of nylon composite LVL. Bonding strength, bending strength,
modulus of elasticity, density and equilibrium moisture content of nylon
composite LVL panels were determined according to TS EN 314-1, TS EN 310, TS EN
323 and TS EN 322, respectively. The experimental results showed that
technological properties of panels generally increased with decreasing pressing
time.

Yaşam alanlarındaki kullanımı genişleyen
ahşap kompozit malzemelerin, insan sağlığı ve çevre üzerinde olumsuz bir
etkisinin olmaması istenmektedir. Ancak odun esaslı kompozit üretiminde
kullanılan tutkalların çoğunun formaldehit içeriği nedeniyle, odun kompozit
malzemelerinin insan sağlığı ve çevre üzerinde bir tehdit oluşturduğu
görülmüştür. Bu nedenle, ahşap esaslı panellerden formaldehit emisyonunu
azaltmak için, etkili bir yöntem geliştirme amacıyla çok sayıda çalışma
yapılmış ve çeşitli yöntemler denenmiştir.



Bu çalışmanın amacı, presleme süresinin
naylon kompozit LVL'nin bazı teknolojik özellikleri üzerindeki etkilerini
araştırmaktır. Naylon kompozit LVL üretmek için Kavak (Populus deltoides) kaplamaları kullanılmıştır. Naylon kompozit LVL
imalatında pres parametreleri olarak üç farklı presleme süresi (8, 10, 12 dakika)
ve presleme sıcaklığı 140 °C seçilmiştir. Naylon kompozit LVL panellerin
yapışma dayanımı, eğilme dayanımı, elastikiyet modülü, yoğunluk ve denge
rutubet miktarı sırasıyla TS EN 314-1, TS EN 310, TS EN 323 ve TS EN 322'ye
göre belirlenmiştir. Deneysel sonuçlar panellerin teknolojik özelliklerinin
genellikle presleme süresinin azalmasıyla arttığını göstermiştir.
