摘　　要：为探研在相同温度下,不同相对湿度对浸渍纸层压实木复合地板坯料热处理净化降醛效果的影响,设定恒定温度60℃,在不同相对湿度条件下,对浸渍纸层压实木复合地板坯料进行1 h热处理净化试验。研究结果显示,在温度60℃、相对湿度为25%时,降醛率为20.0%,降醛效果最为显著。随着湿度增加,降醛率逐渐降低,当相对湿度为60%时,降醛率甚至呈现负向增长。说明在热处理净化时,适当合理的加湿有利于浸渍纸层压实木复合地板坯料中的甲醛释放。This study evaluates the effect of varying relative humidity on the purification and formaldehyde reduction of heat-treated impregnated paper laminate engineered wood flooring.Samples were subjected to a one hour heat treatment at 60 C under different humidity conditions.Results indicated that the optimal formaldehyde reduction rate of 20.0%occurs at 25%relative humidity.Higher humidity levels negatively impact the reduction rate,with a significant decline observed at 60%relative humidity.These findings suggest that controlling humidity levels can enhance formaldehyde release during the heat treatment process.
