Adhesivity of bio-based anhydrous citric acid, tannin-citric acid and ricinoleic acid in the properties of formaldehyde-free medium density particleboard (MDP)
Particles of flooded gum (Eucalyptus grandis) were bonded using three bio-based adhesives - anhydrous citric acid (CA), tannin-citric acid (TCA) and ricinoleic acid (RA) - from renewable sources and hot pressed to produce medium density particleboard (MDP). The bonding capacity of such adhesives and...

| 520 | |a Particles of flooded gum (Eucalyptus grandis) were bonded using three bio-based adhesives - anhydrous citric acid (CA), tannin-citric acid (TCA) and ricinoleic acid (RA) - from renewable sources and hot pressed to produce medium density particleboard (MDP). The bonding capacity of such adhesives and properties of the MDP were evaluated and compared to the requirements of seven grades of particleboards, according to the EN 312 (2010) standard. The RA did not create adhesion reaction with the wood particles. Adhesives formulated with CA and TCA presented capacity to bond eucalyptus particles into MDP confirmed by esterification reactions of the FTIRS analysis. MDP bonded with CA met requirements as high as grade P5 of the EN 312 (2010) standard for static modulus of elasticity (MOE) and internal bond (IB) and P2 for modulus of rupture (MOR). Panels bonded with TCA met requirements up to grade P3 for MOE, however, did not withstand water absorption. | ||
| 520 | |a Za izradu iverice srednje gustoće (MDP) upotrijebljeno je iverje drva eukalipta (Eucalyptus grandis) lijepljeno trima ekološki prihvatljivim ljepilima dobivenim iz obnovljivih izvora na bazi anhidrida limunske kiseline (CA), taninsko-limunske kiseline (TCA) i ricinoleinske kiseline (RA) te prešano u vrućoj preši. Kvaliteta lijepljenja tim ljepilima i svojstva iverice ocijenjeni su usporedbom sa sedam klasa uporabe prema normi EN 312 (2010). Ljepilo RA nije uspjelo povezati drvno iverje. Ljepila CA i TCA pokazala su sposobnost lijepljenja eukaliptova iverja pri izradi MDP ploče, što je potvrđeno reakcijom esterifikacije u FTIR analizi. MDP ploča izrađena primjenom CA ljepila udovoljava visokim zahtjevima klase uporabe P5 prema EN 312 (2010) za modul elastičnosti (MOE) i čvrstoću na raslojavanje (IB) te klase P2 za modul loma (MOR). Ploče izrađene uporabom TCA ljepila ispunile su zahtjeve klase uporabe P3 za modul elastičnosti (MOE), ali nisu zadovoljile zahtjeve o upijanju vode. | ||
