Abstract

Ofis-gazete kağıdı(O/N) ve ofis-karton kağıdından (O/C) yapılan
levhalarda borik asit içeriği arttıkça levhalardaki boyut değişiminin (Suda
şişme; TS) yükseldiği tespit edilmiştir. Ancak %10 borik asit içeren levhaların
Eğilme Elastikiyet Modülü (MOR), %5.0 borik asit içeren levhalara göre daha
fazla olarak kendini göstermiştir. %10 borik asit ilavesiyle en yüksek MOR
değeri, gazete/karton kağıdı (ağırlıkça 3: 1) karışımı için 7.93 MPa olarak
bulunmuştur. Mobilyalarda, levhaların Elastikiyet Modülü (MOE) genellikle borik
asit içeriği%5'ten %10'a yükselirken azalmıştır. Tüm formülasyonlar arasında en
yüksek MOE ofis/gazete kağıdında, 600 MPa standart değerinden oldukça yüksek çıkmıştır.
Bununla birlikte, en yüksek MOE değeri, ofis kağıdı/gazete oranlarının 3:1
(ağırlıkça) karışımı ile 735.63 MPa olarak bulunmuştur. Benzer sonuçlar, MOE’de
olduğu gibi, levhaların yüzeye dik çekme direnci (IB) içinde gözlenmiştir. Genel
olarak, borik asit içeriğinin %5.0'den 10'a çıkarılması, levhaların IB
özelliklerine olumsuz etki eder. Borik asit içeriği ve lif oranı seviyesinin
termal özelliklere (termal iletkenlik;TC) etkileride fark edildi. Borik asit
genellikle yüksek termal direnç sağlar ancak lif oranı ve borik asit katkılı
lif tipinin içeriği önemli olmaktadır. Bununla birlikte, en düşük TC değeri
0.1455 W / mK olan, %10 BA içeriği olan sadece karton kağıdı liflerinden
yapılmış levhalar olduğu bulunmuştur. Sekonder liflerden yapılan levhaların ses
yutma değerleri, sürekli olarak 1600 Hz'e yükselen ve ardından azalan bir ses
sönümlemesi göstermektedir. Levhaların ses yutma özelliklerinin genellikle
düşük frekanslarda daha iyi olduğu anlaşılmaktadır.

Abstract

The change in the
dimension (Thickness Swelling; TS) was found to be high, at high boric acid
content for boards made from Office paper/Newspaper (O/N) and Office paper/Old
Corrugated Container (O/C) types. However, the
boards made with 10% boric acid exhibits higher Modulus
of Rupture (MOR) values than boards made with 5.0% boric acid. The highest
value of MOR was found as 7.93 MPa with the addition of 10% boric acid with
Newspaper/Old Corrugated Containers (3:1 by weight) mixtures. The Modulus of
Elasticity (MOE) of the boards generally decreased with increasing boric acid
content from 5% to 10% in furnishes. The Office paper/Newspaper had the highest
MOE among the all formulations and considerable higher than standard value of
600 MPa.
  However, the highest value of
MOE was found as 735.63 MPa with the mixture of 3:1 (by weight) proportions of
Office paper/Newspaper proportions. The similar results were observed for
Internal Bond (IB) properties of boards, as like MOE. While in general,
increasing boric acid content from 5.0 to 10%, negative effects on IB
properties of boards.
It was also realized that the boric acid content
and fiber proportions effects various level on thermal properties (thermal
conductivity; TC). The boric acid had usually provided higher thermal
resistance, but the difference between fiber proportions and fiber types
consisting of boric acid was important. However, the lowest TC value of 0.1455
W/mK was found the boards made from only old corrugated containers fibers with
10% BA content.
The sound absorption
values of boards made from secondary fibers show a sound damping that it was
steady increase up to 1600 Hz and then
decreasing.
It could be realized that the sound
absorption properties of boards were generally
better than that of in lower frequencies.It was also realized that the boric acid
