THE IMPACTS OF WEATHER TO SCOTS PINE WOOD IMPREGNATED WITH NATURAL AND SYNTHETIC IMPREGNATE MATERIALS

Abstract

Used long-term of wood has been working on importance rinse in each period. Impregnating with different methods in order to fight against factors particularly natural conditions, fungi and insects etc. with different protective materials were protected to wood materials. Mostly meant to be an alternative to impregnation made with natural impregnate materials that are less harmful to human health and the environment against the use of chemicals is of more importance today. In this study, scotch pine (Pinus sylvestris L) wood materials is targeted to test of the physical and mechanical properties in the result of impregnating with pine tannin of natural impregnate material and immersol aqua using synthetic impregnating agent. Impregnated materials have tried to put forward to more advantageous of impregnate materials examining of the physical and mechanical properties wait in the clear weather conditions with a year of time. Impregnation method is applied as dipping method. In this study; air dry density, retention amount, bending strength, modulus of elasticity, compressive strength parallel to the fibers, bonding strength in direction parallel to the fibers and screw holding strength were determined. This study concluded that values of strength retaining screw and parallel shear strength to fibers in samples impregnated with pine tannins were determined higher than immersol aqua. And compressive strength parallel to grain, bending strength, air drying and oven dry density values were determined as the lower. As a result, scotch pine wood impregnated with pine tannin is determined that can be compared level with samples impregnated with immersol aqua.
