Abstract

In this study, it was aimed to investigate the usability of some wastes
such as wood chip screening rejects and kraft pulp screening rejects as fibrous
materials in the manufacture of medium density fiberboard (MDF). Chip screening rejects were refined with a laboratory type refiner;
however, pulp screening rejects were not refined. These materials
were added to commercial fibers with the rates of 10%, 30%. Fiberboards were
manufactured using urea formaldehyde (UF) adhesive. Some properties of these
fiberboards such as water absorption (WA), thickness swelling (TS), surface
roughness parameters, color change, modulus of rupture (MOR) and modulus of
elasticity (MOE) values were determined. As a result of these, it was found
that all values showed different trend depending on rates and types of Kraft
mill wastes.  Generally, the use of these
materials had positive effects on the panel properties.

Some Properties of Fiberboard Manufactured with Wastes of Kraft Pulp Mill

Abstract

Bu çalışmada, odun yonga eleme
atıklarının ve kraft hamuru elek atıklarının lifsel materyaller olarak orta
yoğunlukta lif levha (MDF) üretiminde kullanımının uygunluğu araştırılmıştır. Yonga
eleme atıkları, laboratuvar tipi bir rafinörde liflendirilirken; hamur eleme
atıkları ise rafinör işlemine uğratılmadan kullanılmıştır. Elde edilen lifsel
materyaller ticari liflere %10 ve %30 oranlarında ilave edilmiş ve üre
formaldehit (UF) tutkalı kullanılarak lif levha üretimleri
gerçekleştirilmiştir. Üretilen bu levhaların su alma (SA), kalınlığına şişme
(KŞ) değerleri, yüzey pürüzlülük parametreleri, renk değişim değerleri, eğilme
direnci (MOR) ve eğilmede elastikiyet modülü (MOE) gibi bazı özellikleri belirlenmiştir.
Bu çalışmanın sonucu olarak,  tüm
değerlerin, kraft fabrika atıklarının türü ve kullanım oranına bağlı olarak
değişim gösterdiği belirlenmiştir. Genel olarak, bu atık materyallerin
kullanımının levha özellikleri üzerinde olumlu yönde etkisinin olduğu tespit
edilmiştir.
