Özet

In this study, the effect of residue types (soundwood, branchwood and bark) on the quality properties of particleboards made from the tree of heaven (Ailanthus altissima (Mill.) Swingle) was investigated. For this purpose, the soundwood, branchwood and bark mixed at different ratios were used in the production of particleboards. Modulus of rupture (MOR), modulus of elasticity (MOE), internal bond strength (IB), thickness swelling (TS) and formaldehyde emission (FE) of the specimens were then tested. The chemical and anatomical properties of the residue types were also determined. Residue type was found to have an impact on the properties of particleboards. The addition of bark and branchwood improved the thickness swelling (2 h immersion) and formaldehyde emission. However, use of branchwood negatively affected the thickness swelling for 24 h immersion. Based on the findings of this study, it can be concluded that different parts of Ailanthus altissima (Mill.) Swingle can be used to manufacture particleboard panels. The branchwood and bark contents significantly affected the quality properties of the manufactured particleboards. The chemical and anatomical properties of the branchwood and bark were also found to be parameters influencing the quality properties of the particleboards. The results indicate that the contents of added bark and branchwood should not exceed 10% and 20% respectively.
