Bu çalışmada motorlu testere ile ağaç kesiminde meydana gelen talaşların yonga levha üretimine uygunluğu ve levha özelliklerine etkisi araştırılmıştır. Hammadde olarak sahil çamı, kayın ve dişbudak odunlarından elde edilen motorlu testere talaşı (MTT) ile endüstriyel odun yongaları (EY) kullanılmıştır. Deney levhaları üre formaldehit tutkalı ile 3 tabaklı olarak üretilmiştir. Elde edilen levhaların fiziksel ve mekanik özellikleri standart yonga levha özellikleriyle karşılaştırılarak motorlu testere talaşının yonga levha üretimine uygunluğu belirlenmiştir. Elde edilen sonuçlara göre MTT yongaların yonga levha üretiminde kullanılabileceği ve fiziksel ve mekanik özelliklerin genel amaçlı kullanımlara uygun olduğu değerlendirilmiştir. Deney levhaların mekanik özelliklerinden en yüksek yüzeye dik çekme direnci (IB) 0,51 N/mm2 ile EY kontrol levha grubunda, en yüksek eğilme direnci (BS)12.84 N/mm2 olarak MTT kontrol grubu levhalarında elde edilmiştir.
This study has studied the suitability and impact on the leaf characteristics of the molds occurring in the motor tester and tree cutting. The raw material was used by the industrial wooden yongs (EY) with the engine testere thumb (MTT) obtained from coastal thumb, curtain and dentist wood. The test sheets are produced in 3 layers with the urine formaldehyde attachment. The physical and mechanical characteristics of the obtained sheets are compared to the characteristics of the standard yongga sheet, determined the suitability of the motors to the production of yongga sheet. According to the results obtained, MTT yongs can be used in the production of yong sheets and the physical and mechanical properties are suitable for general use. The highest surface drawing resistance (IB) from the mechanical characteristics of the test sheets was achieved in the EY control sheet group with 0.51 N/mm2 and the highest inclination resistance (BS) 12.84 N/mm2 in the MTT control group sheets.
In this study, the feasibility of using chainsaw dust in particleboard production was investigated. Chainsaw dust chips were used as raw material, obtained from the maritime pine (Pinus pinaster) , beech (Fagus orientalis) and ash (Fraxinus excelsior) woods. Test boards were produced with three layers with urea formaldehyde resin. The physical and mechanical properties of the boards produced were compared with standard particleboard values and the suitability of chainsaw dust for particleboard production was determined. The results indicate that the highest internal bond strength was observed in the industrial chip control group as 0.51 N/mm2 and the maximum bending strength was found in chainsaw control group as 12.84 N/mm2. When the test results are evaluated, using chainsaw chips were found suitable for the production of general purpose particleboard in terms of physical and mechanical properties.
