Permeability of oriented strandboard mats

摘要: This research considered how flake thickness, alignment, and changing mat density during consolidation influences oriented strandboard permeability, through its thickness in the plane of panel. An apparatus was designed to allow cold pressing aligned mats desired densities while enabling permeability measurements thickness. additional measurement mat. These designs permitted that had no vertical gradient, allowing for direct study vs. compaction ratio. Permeability highly dependent on ratio a lesser extent decreased with decreasing flake.thickness. decreases increasing ratio, but less severe manner than Again, From this research, manufacturers can gain better understanding manage gas pressure optimize heat transfer venting hot-pressing.
