Emprenye ve Isıl İşlemin Ahşap Malzemenin Bazı Fiziksel ve Mekanik Özelliklerine Etkileri

The aim of this study was to determine some physical and mechanical properties spruce (Picea orientalis) wood, which impregnated with aqueous solutions valonia (valex) (the extract Quercus ithaburensis), pine bark powder (pinex) (Pinus brutia Ten.) gallnut (galex) (Quercus infectoria Oliver) as a pre-treatment then heat treated. Test specimens were prepared from sapwood wood 10% tannin before treatment base on ASTM D 1413-76. After pre-impregnation processs, subjected at 150 °C, 175 °C 200 for 2 h. effect impregnation process temperature the air-dried density, compressive strength paralell grain (CS), bending (MOR) modulus elasticity in (MOE) analyzed. As results, showed positive effects unheat-treated samples determined that mecnaical loses due slightly limited low temperatures. However, increased increasing temperature. highest also galex heat-treated °C.
