| Résumé : |
Resins were prepared by fortifying urea formaldehyde with tannins of Uncaria gambier and Acacia catechu separately upto 30% at room temperature. Adhesive formulations and gluing conditions were examined by preparing laboratory 3-ply sal boards (53.34cm x 53.34cm). In order to study the effect of fortification of Urea formaldehyde with both the tannins, the gluing results obtained were analyzed and it was revealed that the glue shear strength of the plywood cannot only meet the requirements of the Indian Standards IS: 303-1989, for moisture resistance grade plywood, but also better than control. Hence both the tannins would be desirable fortifiers for urea formaldehyde resin as reducing the cost of the glue without affecting the bond quality of Moisture Resistance (MR) grade plywood. |
