[en] The aim of this work is to demonstrate the performances of Acacia Mangium tannin-based tannin designed as adhesive in the particleboard production. The tannin was extracted from acacia mangium barks in differences medium extraction. Three difference medium, (1)Water (Control), (2)Na₂SO₃ (4 %) / Na₂CO₃ (0.4 %) and (3) Na₂SO₃ (8 %) / Na₂CO₃ (0.8 %) used, the (3) medium extraction produce then highest yield (25.8 %) follow the (2) medium extraction (21.6%) and the less yield (17.7%). To evaluate the mechanical performances of optimal Acacia mangium tannin-based adhesives, particleboard were produced using 3 differences hardener and mechanical properties (Internal bonding) were investigated. The performance of these panels is comparable to those of particle panels commercial. The results showed that particleboard panels bonded with parafomaldehid (0.392 Mpa) exhibited better mechanical properties, continue particleboard panel hardened with hexamine (0.367 MPa) and particleboard panel bonded with glyoxol-tannin based adhesives (0.244 MPa). This show the suitable harder for acacia mangium tannin are formaldehyde > hexamine > glyoxol. (author)
