چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولPhysical and Mechanical Properties of Bio-Composites from Wood Particles and Liquefied Wood Resin
Compression molded composites were made from wood particles and a liquefied wood/phenol/formaldehyde co-condensed resin. Based on our previous research, a phenol to wood (P1W) ratio of 2/1 was chosen for this study. The two experimental variables selected were: 1) liquefaction temperature (1500 and 180°C) and 2) cooking method (atmospheric and sealed). Panels were tested in static bending for m...

متن کاملWood Fuel Properties and Fuel Products from Woods
The fuel properties of wood can be summarized by ultimate and proximate analysis and determination of the high heating value. It is not valid to list these values for species since a species has not been adequately sampled and tested. Enough is known, however, to say that softwoods have a high heating value of about 9,000 Btu per pound; whereas hardwoods have a value of about 8,600 Btu per poun...
متن کاملinvestigating the effect of wood particle size on the rheology and physical-mechanical properties of wood-polypropylene composite
the growing interest in using natural fibers as reinforcing agents of polymer-based composites is mainly due to their advantages such as lower cost, lower density, ease of preparation, lower energy requirements for processing, biodegradability, wide availability and relative non-abrasiveness over traditional reinforcing fibers such as glass and carbon. in this study, wood-plastic composite (wpc...
