some wood physical properties of Platanus orentalies L. grown in Kirkuk '

Abstract

This research was conducted to study the percentages of some wood physical properties of Platanus orfintales L. grown in Kirkuk, the study included oven dry density, basic density, volumetric shrinkage, volumetric swelling, Fiber saturation, Green moisture content, Maximum moisture content, Percentage of cell wall, Percentage of the porosity, These characteristics are important to know because they can be highly dependent on the performance and strength of wood used in many applications such as construction applications and others, and the results are as follows:1-Oven dry density (0.571) g/cm3. 2-Basic density (0.531) g/cm3. 3-Volumetric shrinkage (6.426%). 4-Volumetric swelling (6.934%). 5-Fiber saturation point (12.140%). 6-Green moisture content (74.997%). 7-Maximum moisture content (120.98%). 8-Percentage of cell wall (38.066%). 9-Percontage of the porosity (61.603%). According to this result, the oriental pine wood is of medium density, and there was a positive relationship between dry density, volumetric shrinkage, volumetric swelling, fiber saturation point, and the percentage of wood in the cell walls. , The relationship was inversely related to the maximum moisture content and the percentage of porosity
