Silan ve Parafin İlavesinin Lif Levhaların Bazı Yüzey Özellikleri Üzerine Etkisi

Bu çalışmada lif levha üretiminde ilave katkı maddesi olarak kullanılan iki farklı silan ve parafinin levhaların bazı yüzey özellikleri üzerine etkisi incelenmiştir. Deney levhalarının üretim aşamasında lifler üzerine 2–aminoetil–3 aminopropil trimetoksi silan (Silan A), 3-aminopropyltriethoxysilane (Silan B) ve sıvı parafin (SP) %1,5, %2,5, %3,5 olmak üzere 3 farklı oranda ilave edilmiştir. Elde edilen levhaların FTIR-ATR analizi ile bağ yapısı incelenerek kullanılan katkı maddelerinin etkileri belirlenmiştir. Bununla beraber, levhaların renk değişimi, yüzey pürüzlülüğü ve mantar çürüklüğü sonrası ağırlık kaybı özellikleri belirlenerek bu özellikler üzerine silan ve parafin kullanımının etkileri irdelenmiştir. Elde edilen sonuçlara göre katkı maddesi konsantrasyonu arttıkça levhalarda renk koyulaşması ve yüzey pürüzlülüğünün arttığı tespit edilmiştir. Ayrıca Silan A ve SP maddelerinin katılmasıyla toplam renk değişim değerleri artış gösterirken, Silan B ilavesiyle azalma göstermiştir. Mantar çürüklüğü sonrası ağırlık kayıpları standartlarda belirtilen değerden oldukça yüksek çıkmış ve çürüklüğe karşı bir direnç sağlanmadığı görülmüştür.

The Effect of Silane and Paraffin Addition on Some Surface Properties of Fiber Board

In this study, the effect of two different silanes and paraffin on the surface properties of the boards were investigated. 3-aminopropyltrimethoxysilane (Silane A), 3-aminopropyltriethoxysilane (Silane B) and liquid paraffin (SP) were added to the fibers in the production phase of the test boards in 3 different ratios (%1,5, %2,5 and %3,5) have been added. The bond structure of boards was examined by FTIR-ATR analysis and the effects of the additives used were determined. In addition, the color change of the boards, surface roughness and weight loss after decay test were determined and the effects of silane and paraffin use on these properties were examined. According to the obtained results, it was determined that as the concentration of the additives increases, the color darkening and surface roughness increase. However, while the total color change values increased with the addition of silane A and SP materials, it decreased with the addition of silane B. After decay test weight loss was considerably higher than the standard value and was not found resistance to decay.
