Properties of the Oil Heat-Treated 10 and 15 Years-old Cultivated Tectona Grandis

September 11, 2021 Science and Technology 0

Oil heat treatment was used on ten (10) and fifteen (15) year-old cultivated Tectona grandis (teak) to see if their qualities improved. The middle section of T. grandis was chosen and treated for 2 hours at 160oC, 200oC, and 240oC. Based on their physical and mechanical qualities, the study compared the effectiveness of treated and non-treated T. grandis. Moisture content, maximum density, basic density, and volumetric shrinkage were among the physical tests conducted. The modulus of elasticity (MOE) and modulus of rupture were the focus of the static bending strength test (MOR). The compression test was performed parallel to the grain of the wood (MOR). The physical properties of oil-heated T. grandis are better than untreated wood, although their mechanical properties are slightly reduced. T. grandis that is ten years old has better physical and mechanical qualities than T. grandis that is fifteen years old. The physical and mechanical properties of the heartwood are superior. In general, the oil-heat treatment increases the characteristics of cultivated teak and makes it suitable for a variety of high-value applications.
