Rheological behavior of high-density polyethylene (HDPE)-wood flour composites with different wood contents was examined using steady shear sweep, oscillatory frequency sweep, creep test, and stress relaxation test. The samples were prepared using a melt compounding method in a twin-screw extruder. The results showed that the yield stress did not appear for the composites prepared under the pro...

Wood-plastic composites represent a growing class of materials used by the residential construction industry and the furniture industry. For some applications in these industries, the fire performance of the material must be known, and in some cases improved. Lab-scale fire performance tests allow for comparisons between WPC formulations. At the Forest Products Laboratory (FPL) oxygen index tes...

The use of waste materials to make eco-friendly wood-polymer composites has been explored by many researchers for academic and industrial purposes due the low cost, biodegradability, availability wood flour. Polypropylene (PP)/ground tyre rubber (GTR)/wood flour (WF) were prepared using an internal batch mixer at a temperature 165 °C 8 min, samples injection-moulded 190 with pressure 6 MPa. des...

This paper examines the compressive strength of sodium silicate bonded cores for aluminum casting with different additives. Various materials are used as additives among which it is found that 5% sand size bauxite has the best effect on both gas strength and de-coring 98.5% silica content sand with 70-90 AFS No. with 4% sodium silicate is used. The results indicate that although very good colla...

The objective of this research was to investigate the utilization of olive mill sludge (OMS) as an alternative to wood in the manufacture of the medium density fiberboard (MDF). The MDF panels were manufactured using standardized procedures that simulated industrial production at the laboratory. Six panel types were made from various mixtures of hardwood fiber/dried OMS flour, 100/0, 90/10, 80/...

OBJECTIVE To investigate whether interventions implemented by the UK Health and Safety Executive addressing exposure to isocyanate-based spray paints in motor vehicle repair (MVR), flour dust in craft bakeries, rosin-based solder flux fume (RBSFF) in the electronics industry, metalworking fluids and wood dust coincided with a decline in incidence of work-related short latency respiratory diseas...
