摘要
选用新型木材阻燃剂FRW处理杨木和桦木单板,探讨浸渍工艺条件(浸渍时间和浸渍浓度)、单板厚度、树种等因素对FRW阻燃单板载药量的影响。结果表明:随着单板浸渍时间的增加和浸渍浓度的提高,杨木和桦木的单板载药量均呈上升趋势;树种不同,其载药量存在差异,杨木单板的载药量高于桦木单板;随着单板厚度的增加,单板载药量在整体上呈下降趋势。
The new-type fire retardant FRW was selected to treat poplar and birch veneer, and the influence of the treatment technology conditions including the soaking time and solution concentration, veneer thickness and the timber of different tree species on the fire retardant retention quantity of the FRW fire-retarding veneer was studied. The results showed that along with the prolonging of soaking time duration and increasing of the solution concentra- tion, the fire retardant retention quantity of the poplar and birch veneer both increased. There was difference in the fire retardant retention quantity between the tree species, the fire retardant retention quantity of poplar veneer was higher than that of the birch veneer. At the same time, with the increase of veneer thickness, the fire retardant re- tention quantity showed a downward trend in the overall.
