Pyrite (FeS2) material the feature ability to be impregnated on wood and effects on some technological properties

In this study, It is aimed that the ability of being identifying to be impregnated with pyrite substance that is the one of the resources of our country of larix wood (Larix decidua) in various concentration (1%, 3%, 5%) with boron compounds up to standart of ASTM 1413-76 and identifying the areas of usage in outdoor furniture industry. For that purpose, it is identified that occurrence changes in some physical-mechanical features and relations of wood-water. According to experiment results, while maximum air-dried density is 3% Pyrite + Boric acid (Ba) (0.64 g/cm3) and maximum full-dried density is 3% Pyrite+Boric acid (0.61 g/cm3), in mechanical properties maximum bending resistance is 1% Boric acid (145 N/mm2), elasticity module in bending is 1% Pyrite+Boric acid (18466 N/mm2), pressure resistance is 1% Boric acid (80,49 N/mm2), sticking resistance is 3% Barit+Bx' (0,60 N/mm2) and when it is based on hours by wood and water relations minimum shrinkage value in 6 hours is 1% Borax (% 7,13), minimum expansion in 6 hours is 1% Borax (% 8,11). Key Words: Larex wood, impregnation, pyrite, wet floor, retention.
