Effect of Compression Pre-treatment on Moisture Content and Mechanical Properties of Full-size Poplar Lumber
To shorten air drying time and prevent blue stain for high moisture content(MC) wood,two dimensions of full-size Poplar lumbers were pre-treated using a compression device developing a 40%.compression ratio. After four compressing cycles,moisture content of the lumber samples reduced quickly from initial 175% to 105%,1,09%. It was observed that moisture contents declined dramatically by48%,5,7% following the first compression. Mechanical properties of the compressed lumber samples were tested. The results showed that the compression technique could be used in pre-treatment for full-size lumber drying.
