人工林杉木板材高温和常温组合干燥研究
In this paper, a technique with combination of normal temperature drying and high temperature drying technology was introduced to dry Chinese Fir plantation board, the result with more than one year's researching showed that, the lumber dimension stability after drying was best when dried in combination method, and second when dried in normal temperature kiln while the worst in airdry. Meanwhile, the result also showed that not only was dimension stability increased but also the density of fir was increased, this fact made plantation fir a excellent material in furniture and interior decoration field. So primary conclusion was got that this combining way was considered one kind of lower drying cost, simple way and effective drying methods.
