Özet
It is known that the color and glossiness, properties change with the heat treatment applied to the wood using different methods. In this study, some surface properties [whiteness index value in (//) parallel and (?) perpendicular directions to fibers, color (?a*, ?L*, L*, ?b*, b*, ?C*, a*, C*, ?E*, and h°), glossiness ((//) parallel and (?) perpendicular to fibers at 20°, 60°, and 85°)] and shore D hardness that occur after heat treatment applied to Palo Santo (Bulnesia sarmientoi Lorenz ex Griseb.) wood at 200oC for 3 h were investigated. Multivariate analysis of variance results was found to be significant on all tests. L* (37.87%), a* (91.60%), b* (70.24%) and C* (71.34%) parameters, whiteness index values (57.38% for ? and 81.60% for ?), shore D hardness value (% 7.32) decreased by heat treatment. ho angle increased by 15.63%. While the luminance values decreased at 20° for ? and ?, it increased at 60° for the same directions. In addition; ?L*:-19.73, ?H*: 2.02, ?b*:-15.07, ?C*:-16.01, ?a*:-5.77, and ?E*: 25.49. It has been observed that the surface properties of wood have changed with heat treatment. © 2023, DergiPark. All rights reserved.
