Effect of Electric Field Action Time on Bonding Property of Poplar Wood
Based on experiment of poplar veneers bonded with PVAc in electric field,relationship between electric field action time and shearing strength between the veneers was preliminarily explored. Experiment results showed that the shearing strength was significantly affected by the time. The strength behaved the best when veneer moisture content was 12%, and 185 g/m\+2 of PVAc(content 17%,viscosity 6.0 Pas at 20 )was spread as adhesive under the following condition:room temperature (1724 ),0.450.85 MPa of pressure for 10 h, 30V of electric potential difference among pole plates initiated after 14 h pressing.\=
