Drying Technology for Preservative-treated Populus tomentosa

In order to find a new way for timber preservative drying to produce high quality timber with little loss of preservatives,the timber of fast-growing Populus tomentosa pretreated by preservatives was dried under three temperatures:70℃,75℃,and 80 ℃.A 7 d and 14 d preservative leaching test was conducted to examine the relationship between drying process and preservative leaching.The results demonstrated that high temperature and low humidity would accelerate the loss of preservative,and the optimal drying temperature was 75 ℃.
