摘要：采用辊筒式单板干燥机对尾巨桉、柳叶桉、巨桉、大花序桉、邓恩桉、粗皮桉6种桉木单板进行干燥试验研究,结果表明,树种对单板干燥质量具有极显著影响。从单板终含水率及均匀性看,粗皮桉、尾巨桉和大花序桉较好,邓恩桉干燥速率低,终含水率未达到单板干燥质量要求;从干燥后单板的开裂数量及延长度看,树种间差异不显著;从干燥后单板的翘曲程度看,柳叶桉、粗皮桉和邓恩桉质量较好;从单板干燥过程中节子脱落造成的孔洞增加数看,尾巨桉、邓恩桉和柳叶桉质量较好。总体来看,粗皮桉、尾巨桉、大花序桉和柳叶桉的单板干燥质量较好,可以满足胶合板生产质量要求,邓恩桉和巨桉单板干燥需要进一步研究。
Experiments were conducted to compare drying quality of six species of eucalyptus veneer. Industrial veneer roller dryer was adopted and the tree species were Eucalyptus urophylla × E. grandis,E. saligna,E. grandis,E. cloeziana,E. dunnii and E. pellita. The results showed that the tree species influenced veneer drying quality significantly. Based on the final moisture content（ MC） and the evenness of MC,drying quality was better for E. pellita, E. urophylla× E. grandis and E. cloeziana,but the final MC of E. dunnii did not meet the MC requirements for the low drying rate. There was no significant difference in checks amount and checks length of veneer of these wood species after drying; based on the distortion of veneer,drying quality was better for E. saligna,E. pellita and E. dunnii; as the increased amount of holes by knot dropping in veneer drying process,drying quality was better for E. urophylla × E. grandis,E. dunnii and E. saligna. In summary,the drying quality of E. pellita,E. urophylla × E. grandis,E. cloeziana and E. saligna veneer could satisfy the requirements of plywood manufacturing,but E. dunnii and E. grandis veneer drying need to be studied further.
