Melez Kavak (Populus euramerican I-214) Liflerinin Suksinik Anhidritle Modifikasyonu: II. Üre Formaldehit Tutkalı Kullanılarak Üretilen MDF’lerin Fiziksel ve Mekaniksel Özellikleri

Melez kavak (Populus euramerican I-214) liflerinden üretilen MDFlerin fiziksel ve mekaniksel özelliklerini

Modification of Poplar Wood (Populus euramerican I-214) Fibers with Succinic Anhydride: IInd the Physical and Mechanical Properties of Urea Formaldehyde used MDF

To improve the physical and mechanical properties of MDF, poplar wood fibers (Populus euramericana I-214)were modified with succinic anhydride before the board manufacturing. During MDF production ureaformaldehyde was used at 5% and 8% concentration. Gravity, rupture modulus, tensile strength, waterabsorption, thickness swelling and hardness on MDF boards produced from control and succinylated fibers wereinvestigated. While modulus of rupture and tensile strength of MDF produced from succinylated fibers were increased, waterabsorption, thickness swelling and hardness of these MDF were decreased.
