This work investigates the feasibility of producing low density particleboards using an adhesive system based on sour cassava starch, taking advantage of its adhesive and self-expansion properties. Relevant properties of the produced particleboards were evaluated according to European Standards including: density, internal bond, moisture content and thickness swelling. Low density particleboard...

Maritime pine (Pinus pinaster) sawdust was used to produce liquefied wood by the polyhydric method with acid catalysis. The process was optimized to produce the highest amount of liquefied wood. Wood liquefied at 160oC for 90 min was used in the adhesion tests. The bond strength of veneer glued with ureaformaldehyde and melamine-urea-formaldehyde resins and several mixtures of liquefied wood wi...

The previous study on low mole ratio urea-formaldehyde (UF) and ureamelamine–formaldehyde (UMF) resins synthesized in the typical way as particleboard binders was repeated with the inclusion of a strong acidic reaction step at a mole ratio of 2.7 in the beginning of the resin synthesis procedure. The resulting UF and UMF resins showed longer storageand pot-lives, longer gel times, and the parti...

The physical and mechanical properties of particleboard panels were evaluated relative to various loading levels nanocellulose (NC) boric acid (BA) in the urea-formaldehyde (UF) resin used for panel production. results showed that NC BA reinforcement substantially affected performance panels. It was determined using 3% afforded best thickness swelling (TS), water absorption (WA), moisture conte...
