摘要
A totally bio hardener acting with an unusual and new hardening mechanism derived from the exudate extract of the African trees Vachellia nilotica and Senegalia senegal was used to harden a maritime pine tannin resin without any aldehyde obtaining a completely bio adhesive for interior particleboard. For a density and pH given, the internal bond (IB) values increased simultaneously with the rate of bio-hardener. The optimal dry IB values (0.63 MPa) were obtained with 15% of bio-hardener solids. The low IB value (0.38 MPa) was obtained with 6% of bio-hardener solids. The IB of panels manufactured with UF as hardener are slightly higher than those using the above bio-hardeners.
