investigation on physical and mechanical properties of medium density fiberboard (mdf) made from acacia salicina
in this research the utilization of acacia wood (acacia salicina) in medium density fiber board production was investigated. sample boards were made from acacia fibers at two resin contents (10, 12%), two press temperatures (175, 185 ˚c) and three press times(3, 4, 5 min). the results were analyzed based on a complete randomized design (crd) under a factorial experiment. results revealed that i...

In this study wheat straw was taken from Ankara province. In order to produce dry process MDF, urea formaldehyde resin was used at the ratio of 8 %, 10 % and 12 %, 1 % ammonium chloride was used as hardening agent on the basis of dry fiber weight. On the other hand, 5, 6 and 7 min. pressing times were applied. Alcohol benzene, cold water, hot water and 1 % NaOH solubility of wheat straw were 5....

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 اولEffects of Nano-wollastonite on Physical and Mechanical Properties of Medium-density Fiberboard
Effects of nano-wollastonite (NW) on physical and mechanical properties of medium density fiberboard (MDF) were studied. NW was applied at 5, 10, 15, and 20 g/kg dry weight basis of wood fibers; the results were then compared with control specimens. Two application methods of NW were used: surface and internal applications. Density was kept constant at 0,67 g/cm3 for all treatments and tests we...
متن کاملEffect of Fiber Surface and Mechanical Properties on the Stiffness and Strength of Medium- Density Fiberboard
The mechanical properties of wood-based composites are dependent upon the properties of the wood components (e.g. wood fibers, wood strands) and the manner in which they are combined. The relationship between fiber mechanical properties and fiber-based composites has been discussed in several publications, but is best described in Page et al. (1977). This paper will focus primarily on the influ...
