SOME PROPERTIES OF FIBERBOARDS MANUFACTURED WITH ASH (Fraxinus excelsior L.) SAWDUST.

The objective of this study was to evaluate the effect of ash (Fraxinus excelsior L.) sawdust on the some properties of Medium Density Fiberboard (MDF). The MDF panels were manufactured from pine fibers and ash sawdusts at the different ratios (10%, 15%, and 20%). Some properties of MDF panels such as surface roughness parameters (Ra, Rz), colour change (πE*), water absorption (WA), thickness swelling (TS) were determined depending on the ratio of ash sawdust. As a result, it was found that the surface roughness parameters and colour change values increased with increasing the ratio of sawdust, the highest surface roughness and colour change values were obtained from the panel type C. However, the water absorption and thickness swelling values decreased with increasing the ratio of sawdust. The lowest values were obtained from the panel type C. [ABSTRACT FROM AUTHOR]
