Medium 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....
متن کاملHot-pressing process modeling for medium density fiberboard (MDF)
In this paper we present a numerical solution for the mathematical modeling of the hot-pressing process applied to medium density fiberboard. The model is based in the work of Humphrey [1982], Humphrey and Bolton [1989] and Carvalho and Costa [1998], with some modifications and extensions in order to take into account mainly the convective effects on the phase change term and also a conservativ...
متن کاملMicrostructural analysis of lignocellulosic fiber networks
The structure of wood based medium density fiberboard (MDF) has been studied using synchrotron radiationbased x-ray microtomography (SRμCT.) Fully automated 3D segmentation and analysis routines have been developed in order to gain information about individual fibers, the distribution of the fiber material, fiber orientation, fiber surfaces and size and location of contact areas. Representative...
