thermal properties of wood-plastic composites prepared from hemicellulose-extracted wood flour
hemicellulose of southern yellow pine wood spices was extracted by pressurized hot water at three different temperatures: 140°c, 155°c and 170°c. compounding with pp (polypropylene) was performed by extrusion after preparing wood flour and sieving to determine its mesh size. the ratio of wood to polymer was 50:50 based on oven-dry weight of wood flour. all extraction treatments and control samp...
متن کاملEffect of Species and Particle Size on Properties of Wood-Flour-Filled Polypropylene Composites
Research on wood-flour-filled polypropylene has primarily focused on one species of wood flour and one or two broad particle-size distributions. To fully exploit the use of wood flour as a filler, the effects of species and particle size need to be examined. This study focused on the effects of both of these variables on the properties of polypropylene filled with wood flour. To examine the eff...
متن کاملWeathering Characteristics of Wood Plastic Composites Reinforced with Extracted or Delignified Wood Flour
This study investigated weathering performance of an HDPE wood plastic composite reinforced with extracted or delignified wood flour (WF). The wood flour was pre-extracted with three different solvents, toluene/ethanol (TE), acetone/water (AW), and hot water (HW), or sodium chlorite/acetic acid. The spectral properties of the composites before and after artificial weathering under accelerated c...
متن کاملthe effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
15 صفحه اولDynamic Mechanical Analysis of Compatibilizer Effect on the Mechanical Properties of Wood Flour-High-Density Polyethylene Composites
In this study, effect of MAPE (maleic anhydride polyethylene) as the compatibilizer on the mechanical properties of wood-flour polyethylene composites has been investigated by using Dynamic Mechanical Analysis (DMA). Composites were made at 25% and 50% by weight fiber contents and 1% and 2% compatibilizer respectively. Controls were also made at the same fiber contents without the compatibilize...
