Abstract

By means of the contrast tests of PVAc bonding to aspen veneer in the electric field , the influence of electric field to wood-bonding was preliminarily explored .The results showed that ①the adhesive strength was sigificantly affacted in intensive electricity .②The good adhesive srtengths potential difference of backing plats was distinct in different glue weight technology .For example , 12.0 % moisture content of the fast poplar veneer , PVAc with 17 %solids content , 6.0 Pas viscosity at 20 ℃, and cold-pressed (0.45 ～ 0.85 MPa)to the veneer at room temperature (17 ～ 24 ℃)for 3 hours , as the single spread 120 gm-2 or 185 gm-2 , the good adhesive strengths potential difference of backing plates was 40 ～ 60 V or around 30 V .
