Effects of press parameters on some technological properties of polystyrene composite plywood
Öz: 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

Polistren kompozit kontrplakların bazı teknolojik özellikleri üzerine pres parametrelerinin etkileri
Öz: 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
