Abstract Biochar from bio-waste pyrolysis presents excellent CO 2 sequestration capacity. This study innovated the design of cement-bonded particleboards utilizing a substantial amount 50–70 wt.% pre-soaked biochar to render products carbon-negative. We investigated roles in magnesium oxysulfate cement (MOSC) system and demonstrated good mechanical functional properties particleboards. In prese...

Two experiments were performed to determine the physical and mechanical characteristics of panels consisting of a veneer face and a particleboard core composed of mixed wood particles/powdered-recycled polyethylene (PE) bag waste (MWP) using urea-formaldehyde (UF) resin as a binder. The addition of 25 percent powdered-recycled PE bag waste to the MWP panels did not adversely affect nonaged bond...

The aim of this study was to investigate the effects of thermally compressed veneer laminating on some of the physical and mechanical properties of particleboard. Oriental beech (Fagus orientalis Lipsky) veneers were compressed under various press conditions. Commercially produced particleboard samples were laminated with such compressed veneer sheets. The density, 2-h and 24-h water absorption...

the acrylated epoxidized soy oil (aeso) was synthesized from epoxidized soy oil and its properties were investigated.  wheat straw particle boards were produced by the synthesized resin with 8% and 13% contents based on straws weight at three pressing times: 8,10 and 12 min. boards’ modulus of rapture, modulus of elasticity, internal bonding, minimum degree of thickness change and water absorpt...

Abstract This study was performed to determine the effects of densification process and glue type in wood material on dowel tensile performance. For this purpose, 8 mm 10 diameter dowels were obtained from black poplar ( Populus nigra ) Eastern spruce Picea orientalis L .), which densified at 50% 75% ratios. The bonded with PVAc D-VTKA separately after drilling 18 deep holes edge melamine-coate...

in this study, rice husk and sodium silicate solution were used to produce particleboards. sodium silicate was used as bonding aid by 25, 20, 15, 10, 5 and zero percent (based on rice husk dry weight). to modify the mechanism of bondability, one percent of 4,4’-diphenylmethane diisocyanate (mdi) was added for every five percent less sodium silicate solution. the effect of diisocyanate on bondab...
