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 کاملHypersensitivity pneumonitis related to medium-density fiberboard.
Pneumonitis due to hypersensitivity to wood fiber is mainly associated with the fungus that colonizes it. We present the case of a male affected with hypersensitivity pneumonitis in which the agent implicated was medium-density fiberboard, an engineered product whose main component is pine wood fiber. The causal agent was identified by means of a specific bronchial provocation test.
متن کاملMedium Density Fiberboard from Mixed Southern Hardwoods
Medium-density fiberboards of acceptable quality were made from a mixture of barky chips from 14 southern hardwoods. Boards made from fiber refined at three different plate clearances did not vary significantly in bending, internal bond (IB), or linear expansion. But, lack of replications and the fact that the refiner was not loaded to capacity caused these results to be inconclusive. Increasin...
متن کاملUtilisation possibilities of textile waste for the production of medium density fiberboard
Background and Objective: Nowadays, in metropolitan areas, principled and hygienic waste management is very important. Recycling is one of the most appropriate options in waste management. Hereof, the present study was aimed to investigate the possibility of using textile waste fibers in the manufacture of Medium Density Fiberboard (MDF). Materials and Methods: This experimental study was perf...
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...
