چکیده
In this paper we present a numerical solution for the mathematical modeling of the hot-pressing process applied to medium density fiberboard. We have started our development from the paper of Carvalho & Costa [2] and the model presented by Humphrey in his PhD. thesis [4] with some modifications and extensions in order to take into account mainly the convective effects on the phase change term and also a conservative numerical treatment of the resulting system of partial differential equations.

The target of this study was to investigate the possibility of MDF productionfrom Eucalyptus camaldulensis wood. MDF fibers were produced applying threelevels of steaming time. Laboratory MDF boards were produced using thegenerated fibers and different pressing temperature and time. Physical andmechanical properties of MDF panels were measured using relevant EU testmethods and were statisticall...
متن کاملMedium Density Fiberboard (mdf) Manufacturing
In this study wheat straw was taken from Ankara province. In order to produce dry process MDF, urea formaldehyde resin was used at the ratio of 8 %, 10 % and 12 %, 1 % ammonium chloride was used as hardening agent on the basis of dry fiber weight. On the other hand, 5, 6 and 7 min. pressing times were applied. Alcohol benzene, cold water, hot water and 1 % NaOH solubility of wheat straw were 5....
