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 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...
متن کاملThe effect of press temperature on properties of medium density fiberboard produced from Eucalyptus camaldulensis fibers
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...
