Abstract:

On the base of a study by author, a new kind of environmental compound modifying agent was studied which was a solution consisting of the ACQ preservative and friendly UF. Impregnated by the vacuum, pine thinning wood could be preservative and reinforced. Mechanism and effect of compound modification were studied more intensively. When the soaked wood was carried on superficial densely processing with the compression ratio 20%, all indexs above mentioned increased above 51% compared to the control samples. The soaking material and the ACQ soaking material were respectively carried on boil the anti-draining contrast experiment and the anti-water, the acid, the alkali extracts, indicated which its processing material had the enhancement compare with alone the soaking ACQ processing material. With tracing on the cupric ion by the X_ray fluorescence spectroscope, content and the distribution of compound modifier was determined cupric ion tracing method might serve for the on-line examination of the production process.

Key words: thinnings wood of Cunninghamia lanceolata, ACQ preservative, UF resin, compound modification, anti_draining, X_ray fluorescence spectroscope
