Technological Properties Of Limba (Terminalia Superba) Wood Impregnated With Imersol-Aqua

Author(s): Hakan Keskin and Mustafa H.Colakoglu

The aim of this study was to investigate the effects of impregnation with imersol-aqua on the some technological properties of limba (Terminalia superba) wood. For this aim, limba wood samples were prepared according to TS 2472, TS 2595, TS EN 408 and impregnated with imersolaqua by the method of short, medium and long-term dipping according to ASTM D 1413 and producers’ definition. After the impregnation process, the densities, compression strength, bending strength and modulus of elasticity in bending (MOE) was measured according to TS 2472, TS 2595 and TS EN 408. Consequently, the retention amount of imersolaqua increased by the period of impregnation and found the highest in the long-term dipping. Densities and strength values of impregnated samples increased with respect to control samples in the long-term dipping. Full-dry density increased 14%, air-dry density increased 9%, bending strength increased 16% and compression strength increased by 19% by long-term dipping method. Modulus of elasticity in bending decreases by short-term or medium-term dipping but remains the same in longterm dipping. So, impregnation by imersol-aqua affects the mentioned properties of wood positively. If the density, bending strength, compression strength and modulus of elasticity in bending is important factors in the limba wooden construction and furniture elements, impregnation by long-term dipping method is suggested.  2006 Trade Science Inc. - INDIA
