摘要:
<正>在温度为100℃、相对湿度为100%的条件下,分别对马尾松(PinusmassonianaLamb.)锯材汽蒸处理2,2.5,3h,其脱脂率逐渐增加,分别为46.24%、48.80%和55.04%。对经汽蒸处理2.5h的马尾松锯材,分别在140、160和180℃的条件下进行热压干燥,发现其脱脂率随着温度的升高而增加;与气干材相比,其累计脱脂率分别为63.82%、66.76%和67.82%。
Abstract:
In order to find the effect of steaming and drying temperature upon deresination of the P.massoniana lumber,improve the drying rate and quality of wood,the P.massoniana lumber was pretreated with steam within different time and then dried at different platen temperatures.This study shows that when the lumber was treated in 2,2.5 and 3 h at 100 ℃ with relative humidity of 100%,the rate of deresination increases and the values are 46.245%,48.80% and 55.04% respectively.After being treated with steaming in 2.5 h,the lumber was dried at 140,160,180 ℃ platen temperatures correspondently.The rate of deresination increases along with the platen temperature and the values are 63.82%, 66.76% and 67.82% respectively in comparison with airseasoned timber.
