Characterization of enzymatic hydrolysis lignin (EHL) and alkaline extracted lignin (AEL) from three different steam refining conditions.
Comparison of EHL and AEL with an organosolv (OL) and kraft lignin (KL) regarding chemical composition, molecular weight distribution, OH group quantification by 31P NMR spectroscopy and Mannich reactivity.
EHL and AHL after mild steam refining showed high suitability as substitutes in LPF resins comparable to OL- and KL-PF references.
High dry and wet internal bond of particleboards bonded by LPF resin with EHL and AEL.
LPF with AEL fulfilled mechanical requirements of European Standard P7.
