| DOR:98.1000/1735-0913.1398.34.74.66.1.1578.1576 هدف از این تحقیق، تأثیر روش انبارداری فله ایی باگاس بر خصوصیات مکانیکی و فیزیکی تخته خرده چوب ساخته شده از آن بوده است. برای این منظور از باگاس مغز زدایی شده به روش مرطوب استفاده شد. شرایط انبارداری باگاس عبارت از دو مقدار رطوبت 45 و 55 درصد و 4 زمان انبارداری 1/5، 3، 4/5 و 6 ماه بود. با توجه به متغیرهای فوق ابتدا ویژگی های شیمیایی باگاس (pH، ظرفیت بافرکنندگی اسیدی و قلیایی) تعیین گردید. سپس نسبت به ساخت تخته خرده چوب اقدام شد و خواص فیزیکی و مکانیکی آنها اندازه گیری و مورد تجزیه و تحلیل قرار گرفت. نتایج نشان داد که با کاهش رطوبت باگاس، pH و ظرفیت بافرکنندگی قلیایی آن کاهش و ظرفیت بافرکنندگی اسیدی باگاس افزایش یافته و ویژگی های خمشی (مدول الاستیسیته و مقاومت خمشی) و مقدار واکشیدگی ضخامت پس از 2 و 24 ساعت غوطه وری در آب تخته ها تضعیف شده است. ویژگی های شیمیایی باگاس با افزایش زمان انبارداری تا 3 ماه، تمایل به اسیدی شدن داشتند و حداقل ویژگی های خمشی و مقاومت به چسبندگی داخلی تخته ها در زمان انبارداری فوق ملاحظه گردید. همچنین با افزایش زمان انبارداری، مقدار واکشیدگی ضخامت پس از 2 و 24 ساعت غوطه وری در آب تخته ها بهبود یافت. | ||

| DOR:98.1000/1735-0913.1398.34.74.66.1.1578.1576 In this study, the effect of piling storage method of Bagasse was studied on the physical and mechanical properties of particleboard. Wet depitted Bagasse was used. In this study, Bagasse storage conditions included two moisture content (45% and 55%) and 4 storage times (1.5, 3, 4.5, 6 months). At the first, Bagasse chemical properties (pH, acid and alkaline buffering capacity) were determined. Then particleboards were fabricated. The physical and mechanical properties of the boards were measured and statistically analyzed. The results showed that at lower Bagasse moisture content, the sample pH and alkaline buffering capacity were decreased and acid buffering capacity increased. Also board bending properties (modulus of rupture and modulus of elasticity) and thickness swelling after 2 and 24 hours immersion in the water were reduced. Bagasse chemical properties tend to be acidic up to storage time of 3 month and the minimum of board bending properties and internal bond were obtained in this storage time. The physical properties of boards were improved with increasing of storage time. | ||
