摘　　要：本文研究了桉木单板阻燃浸渍处理过程中单板厚度、单板含水率及浸渍条件等因素对载药率的影响。结果表明:处理液浓度、浸渍时间和处理液温度与单板载药率呈显著正相关性;随着单板厚度和含水率的增加,单板载药率呈减小趋势;正交试验优选出的最佳浸渍工艺条件为处理液浓度30%、浸渍时间12 h、处理液温度70℃,且处理液浓度对单板载药率的影响最大。综合考虑,建议在实际生产中通过改变处理液浓度来调整单板载药率。The effects of veneer thickness, moisture content（MC） of veneer and impregnating processes on the fire retardant loading for veneers of Eucalyptus species were investigated. The results indicated that solution concentration, impregnation time and solution temperature had a significant positive correlation with fire retardant loading of veneers, while the loading decreased with the increase of both thickness and moisture content（MC） of veneers. An orthogonal experiment conducted showed the optimal group to consist of using a solution concentration of 30%, an impregnation time of 12 h and a solution temperature of 70 oC. The factor with the biggest influence on fire retardant loading of veneers proved to be the solution concentration. It is suggested that solution concentration could be used to adjust the fire retardant loading of veneers..
