Abstract

Abstract:

The anti-swelling effectiveness(ASE)and MOE/MOR of masson pine and poplar treated by chlorothalonil,ACQ and copper citrate were conducted according to Chinese national standard in this paper.The results indicated that chlorothalonil had little effect on ASE of Populus tomentosa at the retention of 11.48 kg/m3 while the ASE of treated wood at other retention increased between 3.9%～28.0% in soaked condition according to GB1934.2-91.MOE of Pinus massoniana treated with chlorothalonil,ACQ and copper citrate was not significantly changed as the control,but MOE of Populus tomentosa treated with ACQ and copper citrate increased 6.3%～8.1%.MOR of both Pinus massoniana and Populus tomentosa treated with Chlorothalonil,ACQ and copper citrate was not significantly changed.

Key words: Chlorothalonil, ACQ, Copper citrate, Dimensional stability, MOE/MOR
