预处理对杨木单板染色和阻燃性能的影响
Effect of pretreatment on dyeing and fire-retarding properties of poplar veneers
摘要
Abstract
In order to improve the permeability of wood veneer, different duration of hydrothermal treatment ( room temperature and 80℃) and 4 g��L-1 NaOH solution were used to pretreat wood veneers and followed by acid dying and BL-flame retardants applica-tion. Dye uptake, oxygen index, light fastness and water fastness of veneer were measured. Results showed that all pretreatments in-creased the permeability, dye uptake and oxygen index of veneers. Hydrothermal treatment improved light fastness and water fast-ness, while quality of veneers under NaOH treatment was averagely poor, and part of veneer surface was even black. Water fastness of immersing in 8 g��L-1 NaOH solution for 40 min was the worst approach, resulting in the maximum color difference at 16. 172 NBS. Nevertheless, the optimal pretreatment process was to pretreat veneer in 80 ℃ hot water for 5 hours, with maximum dye up-take rate at 44.88%, best light fastness at 5.563 NBS and other two indexes meeting the requirements of wood veneer.关键词
