Title

Investigation on the physical properties and internal bonding of HDF made of oxidized fiber

Pages

  127-135

Abstract

 Current research was conducted to investigate the physical properties and internal bonding of high-density fiberboard (HDF) made from oxidized fibers and different amount of glue. For surface modification, fibers were treated with 40% nitric acid. After gluing fibers with urea-formaldehyde (7% and 9% based on the dry weight of fibers), the boards with a the density of 0. 9 g/cm3 were made by hot pressing at 175° C in 4 minutes. The results of spectroscopy confirmed the reduction of hydroxyl functional groups and the increase of the carboxylic group due to oxidation. The results of short term immersion test in water showed that in boards containing oxide-modified fibers and 9% ureaformaldehyde glue, the minimum water absorption and thickness swelling were obtained with the means of 78. 5 and 28. 65%, respectively. Spring back of modified boards containing less glue was affected by the stresses release and debonding of the wood elements that resulted in internal bonding loss.
