摘要
为高效利用柳杉木材,采用高温干燥方法对25mm厚柳杉心材、边材及心边混合锯材进行干燥,并检测干燥速率及干燥质量。结果表明,边材干燥速率最快,心材最慢;心材-弦切板、心边混合材-弦切板的干燥质量,可以达到GB/T 6491-2012《锯材干燥质量》中的二级要求。
High temperature drying experiments were conducted on 25 mm-thick Cryptomeria lumber. Also investigated was Cryptomeria heart wood, sapwood and heart-sap-mixed lumber drying rate and drying quality. The results showed that sapwood drying rate was the fastest and that heartwood was the slowest. Flat-sawn heartwood and heart-sap-mixed lumber can meet the Chinese National Standard GB/T 6491 2012 second grade requirements.
