摘要
针对白桦存在的干燥变色这一缺陷,从干燥变色规律方面展开系统研究,结果表明,白桦木材材色随干燥温度和相对湿度的增加而加深,80℃和70%的相对湿度是材色速增的临界值。
In order to reduce or remove the defect of Betula platyphylla,wood discoloration discipline was studied systematically,which provided theoretical foundation for prevention,processing and utilization of drying discoloration.The results showed that the wood color was deepened with the increasing of drying temperature and relative humidity,and 80℃ and 70% were the critical values of accelerated growth for wood color.
