Effects Of Upper Surface (Nanotechnology Varnish) Materials On Technological Properties Of Unimpregnated/Impregnated Wood

In this study, spruce wood’s boric acid and nano technological varnish different vacum/ diffusion in time impregnating with respect to ASTM 1413-76 standards and the changes on technological features are researched. Retention percent, bending strength, modulus of elasticity were determined. According to the results of the experiment; the highest retention was 40 minutes vacuum and 60 minutes diffusion (8.35%), the lowest 20 minutes vacuum, 60 minutes diffusion (3.10%); The mechanical properties of the high bending resistance value of 20 minutes vacuum at 60 minutes diffusion (89.68 N/ mm2) and modulus of elasticity in bending highest nano technological varnish (10300 N/ mm2 were determined.
