| Abstract | ||
| The force of urea-starch origin adhesive was studied on the (wood-wood) surfaces in all experimental to know the convenient it in wood industries. We found the maximum shear stress (0.543N/mm2), Elongation (1.41%) and modulus (2 N/mm2) when curing temperature (25oC) for curing time (7 days).Also the adhesive was cured at temperature (160oC) for different curing time (10, 20, 30, 50 Min.). The result was found the maximum shear stress (0.896N/mm2), Elongation (1.7%) and modulus (1.3 N/mm2) at curing time (10Min.). The effective of adhesive by immerse in water and absolute ethanol also studied. The more effected in adhesive was by water and was increasing the swelling with increased the time. When immerse the adhesive materials in ethanol was very limited affected and the swelling was nearly stable in the period of time from (10Min.) to (50Min.).The weight loss with time was studied at the temperatures of 160 oC. The amount of weight reduction was increased with the time. | ||
