Cellulose nanofibrils (CNF) were investigated as a binder in the formulation of particleboard (PB) panels. The panels produced four different groups target densities with varying amounts CNF binder. then tested to determine modulus rupture (MOR), elasticity (MOE), internal bond (IB), water absorption (WA), and thickness swelling (TS) properties. Density gradients through evaluated using an X-ray density profiler. effect drying on strength development adhesion between wood particles (WP) was...
Abstract The novel use of aqueous suspensions cellulose nanofibrils (CNF) as an adhesive/binder in lignocellulosic-based composite manufacture requires the removal a considerable amount water from furnish during processing, necessitating thorough understanding dewatering behavior referred to “contact dewatering”. wood-CNF particulate system (wet furnish) was studied through pressure filtration tests, centrifugation, and characterization hard-to-remove (HR) water, i.e. moisture content wet at...
Abstract The effect of three different types cellulose nanofillers on the morphology, mechanical, and thermal properties flexible polyurethane foam was studied. Cellulose nanocrystals (CNC), nanofibrils (CNF), filaments (CelFil) were used as fillers at 0.1–0.8 wt% loading levels. comparison results showed that smaller levels resulted in foams with better performance almost all cases. In next step, containing CNC, CNF, or CelFil 0.025%–0.1% compared those made inorganic including nanosilica...
Utilization of cellulose nanocrystals as an additive in the formulation biocomposites made with Acrodur® resin is presented. Natural fibers/polyethylene terephthalate mats were impregnated and hot-pressed into final thickness 3 mm after drying. Biocomposites 2 wt.% 5 nanocrystal (dry-basis) also produced. The produced biocomposite panels then tested to determine flexural strength, modulus Izod impact strength. results revealed that adding composite increased significantly up 970 MPa (17.5%...
