Performance of Brutian Pine (Pinus brutia Ten.) Particles Modified with NaOH in Board Production

Öz

In this study, particles from brutian pine (Pinus brutia Ten.)  were soaked in 0.25, 0.50, 0.75 and 1% NaOH solutions. The changes in the chemical and thermal properties of the particles caused by these treatments were indicated and the effects of these treatments on the physical and mechanical properties of the produced boards were evaluated. Main chemical component and fourier transform infrared (FTIR) spectroscopic analysis showed that the extractive, hemicellulose and lignin content of the particles decreased during the alkali treatments, while the cellulose content increased. Thermogravimetric analysis (TGA) indicated that the particles treated with NaOH solutions exhibited lower thermal stability than the untreated particles. Alkali treatments caused water absorption (WA) and thickness swelling (TS) increase of the produced particleboards. The mechanical properties of the produced particleboards were improved by alkali treatments. The modulus of elasticity (MOE), modulus of rupture (MOR) and internal bond (IB) strength values of the produced particleboards met the requirements for general-purpose particleboards used in dry conditions, as defined by the TS-EN 312 (2012) standard.

NaOH ile Modifiye Edilmiş Kızılçam (Pinus brutia Ten.) Yongalarının Levha Üretimindeki Performansı

Öz

Bu çalışmada, %0.25, 0.50, 0.75 ve 1’lik NaOH çözeltileri ile işlem görmüş kızılçam (Pinus brutia Ten.)  yongalarının kimyasal bileşimindeki ve termal özelliklerindeki değişimler ve bu değişimlerin üretilen levhaların fiziksel ve mekanik özellikleri üzerine etkileri değerlendirilmiştir. Ana kimyasal bileşen ve fourier dönüşümlü kızılötesi (FTIR) spektroskopisi analizleri, alkali işlemlerde NaOH derişimi arttıkça yongalardaki ekstraktif madde, lignin ve hemiselüloz miktarlarında sürekli düşüş, selüloz miktarında ise sürekli artış olduğunu göstermiştir. Termogravimetrik analiz (TGA) sonuçları, alkali işlemin yongaların termal dayanıklılığını düşürdüğünü ortaya koymuştur. Uygulanan alkali işlemler, üretilen levhaların su alma (SA) ve kalınlığına şişme (KŞ) değerlerini sürekli artırmıştır. Üretilen levhaların mekanik özelliklerinin uygulanan alkali işlem derişimi arttıkça gelişme gösterdiği belirlenmiştir. Çalışmada üretilen levhalarda belirlenen eğilmede elastikiyet modülü (EM), eğilme direnci (ED) ve yüzeye dik çekme direnci (YDÇD) değerlerinin TS EN 312 (2012) standardında belirtilen kuru şartlarda genel amaçlı kullanılan levhalar için beklenilen değerlerden yüksek olduğu görülmüştür.
