摘要
人造板的室外自然老化和加速老化，以及两者之者的等效性试验结果表明：３年的自然老化和ＢＳ法的老化程度相当，喷蒸和沸煮或夏天的高温和雷雨对板材性能影响最显著，性能下降幅度随暴露时间的延长而减少；ＰＦ胶胶结或纤维间靠木素胶合和氢键结合的人造板较氨基树脂制造的人造板耐候性强．
of natural weathering and accelerated ageing for woodbased panels indicated that threeyear-weathering and ageing by BSmethod showed the same degree of effect.Steaming,boiling,or high temPerature and thunderstorm in were found to have the strongest weathering effect on the properies of the board.The longer exposure time,the less the degree of weathering.PF-and ligin-glued or hydrogenbond jointed exhibited greater weatherability than UF-glued board.
