Some chemical properties of these annual plants were investigated to find out their chemical characteristics in wood composites production. In all board variants 100% of the middle layers consisted of chips from one of the above annual plants. Reference boards were 100% beech wood. Laboratory manufacturing treatments included two panel density levels (500 and 600 kg/m3) and three resin types (urea-formaldehyde, melamine-urea-formaldehyde and wheat protein). Water absorption and thickness swelling of the laboratory manufactured boards were improved by adding melamine to urea-formaldehyde resin and by adding water repellent chemicals. The mechanical properties of the boards produced met the requirement for the general purpose product standards (EN 312-2) at both 500- and 600- kg/m3 densities. Decreasing the density, negatively affected the bending (modulus of rupture) and internal bond properties of canola boards. This decreasing trend was also observed for modulus of rupture values in bagasse boards of 500 kg/m3 density. Based on the results of the chemical analysis, it might be concluded that high values of ash content and lower values of hemicellulose and lignin content caused low physical properties and/or high water absorption of canola boards. The findings indicated that hemp and bagasse are valuable renewable natural resources for particleboard production and could be utilized as a substitute for wood in board production. In comparison with the reference boards, mixed variants boards showed surprisingly good results and generally conformed to European standards (EN 312-2) values."],["dc.identifier.doi","10.5539/jmsr.v2n2p126"],["dc.identifier.fs","592005"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/10999"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/58159"],["dc.language.iso","en"],["dc.relation.issn","1927-0593"],["dc.rights.access","openAccess"],["dc.title","Use of MUF Resin for Improving the Wheat Protein Binder in Particle Boards Made from Agricultural Residues"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

The results reveal that most of the investigated mechanical-technological properties of the boards achieved the requirements of EN 312-2 (2003). Only increasing the percentage of canola chips usage in the middle layer to more than 30% negatively affect the internal bond (IB) properties. Comparing the water absorption (WA) and thickness swelling (TS) values, the boards containing up to 50% bagasse and hemp reach similar values to the ones of the reference boards, while increasing the amount of canola leads to more and more disadvantageous WA and TS. In summary, the results reveal that agri-fibers can be used for making composite panels conforming to the standards (EN 312-2 2003). One possible application for these panels could be the production of furniture."],["dc.identifier.doi","10.1007/s00107-010-0465-3"],["dc.identifier.isi","000281072200009"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/4967"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/19308"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","0018-3768"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Comparative properties of bagasse, canola and hemp particle boards"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
