Determination of The Physical And Mechanical Properties of Scotch Pine By Impregnating With OAK Tannin And Timber Care Impregnation Materials

Abstract

In this study, it is aimed to test the preservative impregnation characteristics of the scotch pine wood type as a consequence of impregnation with natural and chemical impregnation materials. The impregnated materials have been kept in outdoor conditions for one year and it is aimed to reveal which one of the impregnated materials is more advantageous by analysing the physical and mechanical properties of materials impregnated under these circumstances. The scotch pine (Pinus sylvetsris L.) is used as the wood material. The acorn has been used as the natural impregnation substance and timber care aqua as the chemical impregnation material. Physical and mechanical tests regarding air-dried density, full dried density, moisture content, retention amount, bending strength, elastic modulus, bonding strength parallel to the fibers, compressive strength parallel to the fibers, and the screw holding strength have been carried out. According to the results regarding the physical properties; full dried density and retention amount of the scotch pines have been confirmed to be higher than control samples in terms of the material, and the airdried density, moisture content and retention amount of acorn specimens have been found to be higher than the timber care aqua samples in terms of impregnation materials. As for mechanical properties, the scotch pine’s elastic modulus and compressive strength parallel to the fibers have been stated to be higher than the control samples in terms of material and bending strength and bonding strength parallel to fibers of acorn samples have been detected to be higher than timber care samples in terms of impregnation materials. As a result, it is determined that the wood materials impregnated with natural impregnation materials are in a state in which they can be compared with the wood material impregnated with a chemical substances.
