近年来,我室进行了以常压过热蒸汽为介质对木材进行高温干燥的工艺试验,取得了较好的效果,并已在不少地区推广。但生产实践表明,此种干燥方式对于松、杉、椴、色等木材,干燥速度快,质量较好;对于石楠、红青冈、野柿子、酸枣等木材,干燥速度较慢,但效果较好,而对于麻栎、苦储、核桃楸等木材,还未能取得明显的成效。为什么同一干燥方式对于不同木材的效应有很大的差别?为了找出原因,以便采取改进的措施,我室从对木材的干燥性质的分析入手,对这个问题进行了研究,初步摸索到
In recent years, I conducted a room at atmospheric pressure superheated steam as the medium of high temperature wood drying process, and achieved good results, and has been promoted in many areas. However, production practice shows that the drying method for pine, fir, linden, color and other wood, fast drying, good quality; for heather, red glauca, wild persimmon, jujube and other wood, the drying speed is slower, but the effect is better , But for the Quercus, Kucu, Juglans mandshurica and other wood, but also failed to achieve significant results. Why does the same drying method have different effects on different kinds of wood? In order to find out the reason and take some improvement measures, our lab started with the analysis of the drying properties of wood and conducted a preliminary study on this issue
