In order to overcome the above-mentioned negative effects, the extractives of the fresh Cunninghamia lanceolata shavings, which were obtained by using both the sorbitic-extracting approaches, were analyzed by ZETA and SIZER to find out the leaching rule of nano particles in Chinese-fir wood. The results are as follows: (1) The extraction mass arrived at the maximum value when NaOH concentration is about 18.5. The micro/nano particles in Cunninghamia lanceolata shavings would be discharged sufficiently in the NaOH solution with the increaing of ...
