Abstract This study explores the possibility of developing a new class hybrid particulate-filled biocomposites using wood flour and rice husk wastes as environmentally friendly additives to poly(lactic acid) (PLA) matrix material. Samples were prepared with fillers different concentrations (0, 2.5, 5, 7.5 10 wt %), while ratio was fixed at 1:1 in all cases. The preparation performed through ext...

Simulation results for mixing of two different polymers in a co-rotating twin-screw extruder are presented. Velocity distribution predicted by a threedimensional simulation of the flow is used to predict the change in the spatial distribution of initially segregated particles as well as the reduction in radius due to erosion. The predicted particle distribution is used to estimate the increase ...

Soda lignin was divided into two fractions with different molecular weights by methanol extraction. Lignin amine was synthesized from the low-molecular-weight lignin fraction via Mannich reaction and was used for interfacial modification of poly-(vinylchloride) (PVC)/wood-flour composites. The PVC/wood-flour composites were prepared from surface-treated wood flour and PVC by melt compounding. T...

Extrusion cooking is a continuous mixing, cooking, and forming processing method. The main objective of the study was to determine effect inclusion chemical silage residues from benefit trout (Oncorhynchus mykiss) in extrusion process food diet for fish. evaluation hydrolyzed protein flour (HPF) carried out simple screw extruder, using 2k factorial design, with four factors: temperature profile...

Polylactide (PLA)/wood flour composite foam were prepared through a batch foaming process. The effect of the chain extender on the crystallization behavior and dynamic rheological properties of the PLA/wood flour composites were investigated as well as the crystal structure and cell morphology of the composite foams. The incorporation of the chain extender enhanced the complex viscosity and sto...

Biomass materials are being investigated and utilized in an ever-widening sphere of industrial scale applications. As this realm of utilization expands, fundamental knowledge of potential feedstocks becomes paramount. This study was undertaken to observe the chemical composition and thermogravimetric behavior of one set of biomass materials. This set includes fibers or ground portions of: corn ...

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...

Wood-based materials are used extensively in residual construction worldwide. Most of the adhesives used in wood-based materials are derived from fossil resources, and some are not environmentally friendly. This study explores nanofiber technology as an alternative to such adhesives. Previous studies have shown that the three-dimensional binding effects of cellulose nanofiber (CNF), when mixed ...

Advocacy on the utilization of locally grown crops keeps increasing. This study was however carried out to evaluate qualities extruded snacks from blends yellow cassava and sesame seeds flour. The fleshed roots (germinated fermented) were dried, milled sieved prior further analysis. Flour each processed seed blended with flour at substitution levels 0, 15 30%. Functional anti-nutritional analys...

the presented study shows a simple way for optimization of extrusion process, which was used for deterioration of cyanogenic glycosides – antinutritive components of linseed, with minimum damage of essential alpha-linolenic acid (ala) at the same time. extrusion of the material was done on a laboratory single screw extruder. content of hydrogen cyanide (hcn) as a measurement of cyanogenic glyco...
