Sobre IBD

La lignina, la più grande fonte naturale di polimeri fenolici aromatici, ha un grande potenziale di utilizzo nella sintesi di nuovi adesivi, a condizione che la sua reattività venga alterata modificando la sua struttura chimica. La reattività della lignina dipende dalla frequenza delle sue unità monomeriche e può essere alterata attraverso processi di demetilazione e fenolatura. Il libro propone un’analisi della resistenza al taglio al filo di colla del legno di Eucalyptus sp. utilizzando adesivi prodotti con lignina Kraft demetilata con acido cloridrico e fenolizzata. In questo contesto, gli adesivi a base di lignina potrebbero essere raccomandati per test industriali nell’incollaggio di pannelli di legno.
