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 کاملEffect of Fiber Surface and Mechanical Properties on the Stiffness and Strength of Medium- Density Fiberboard
The mechanical properties of wood-based composites are dependent upon the properties of the wood components (e.g. wood fibers, wood strands) and the manner in which they are combined. The relationship between fiber mechanical properties and fiber-based composites has been discussed in several publications, but is best described in Page et al. (1977). This paper will focus primarily on the influ...
متن کاملProperties of Medium-Density Fiberboard Related to Hardwood Specific Gravity
Boards of acceptable quality were made from barky material, pressure-refined from 14 species of southern hardwoods. Static bending and tensile properties (parallel to surface) of specimens were negatively correlated to stem specific gravity (wood plus bark), chip bulk density, and fiber bulk density. Bending and tensile properties increased with increasing densification ratio, but the rate of i...
