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 کاملDurability of wood plastic composites manufactured from recycled plastic
The influence of accelerated weathering, xenon-arc light and freeze-thaw cycling on wood plastic composites extruded from a recycled plastic was studied. The results showed that, in general, weathering had a stronger impact on samples made from plastic waste compared to a sample made from virgin material. After weathering, the mechanical properties, tensile and flexural, were reduced by 2-30%, ...
متن کاملWood–Polymer Composites Prepared by the In Situ Polymerization of Monomers Within Wood
Wood–polymer composites (WPCs) were prepared from poplar wood (P. ussuriensis Komarov) in a two-step procedure. Maleic anhydride (MAN) was first dissolved in acetone and impregnated into wood; this was followed by a heat process; and then, glycidyl methacrylate (GMA) and styrene (St) were further impregnated into the MAN-treated wood, followed by a second thermal treatment. Finally, the novel W...

متن کاملSome of the Properties of Wood Plastic Composites
In this study some of the important properties of experimentally manufactured wood– plastic composites (WPC) were determined. Specimen having 60% and 80% particle and fibre of radiata pine (Pinus radiata ) were mixed with polypropylene (plastic) and four different additives, namely Struktol TR 016 which is coupling agent, CIBA antimicrobial agent (IRGAGUARD F3510) as fungicide, CIBA UV filter c...
