户外用蜡浸注木工艺及物理力学性能
Impregnating technology and physical mechanics properties of wax impregnated wood for outdoor use
摘要
Abstract
In order to improve the performance of wood in outdoor application, polyethylene wax with high melting point was used for high pressure impregnation treatment to common wood and the physical and mechanical properties of wax impregnated wood were measured. The results showed that the wax in the molten state was stable with low viscosity, good fluidity, and penetrable into pore of wood under pressure. Wood permeability was the decisive factor of wax impregnation. In terms of permeability, Pinus sylvestris and Pinups radiata wood were outstanding, Eucalyptus saligna wood was moderate, Picea abies wood and Picea glauca wood were weak. Impregnating was help to slightly increase the hardness, the modulus of elasticity and water absorption but significantly decrease bending strength and tensile strength. The three stage impregnation process can make whole section of Pinups sylvestris and Pinups radiata wood full of wax in a value of 40.21% and 41.45% respectively. Due to excellent resistance to freeze-thaw and UV aging, Pinus sylvestris and Pinups radiata wax impregnated wood were the applicable outdoor wood for structural engineering.关键词
