Abstract: By means of the contrast test of PVAc bonding to sakhu vener in the setting plate on potential difference,the influence of potential difference of setting plate to sakhu bonding was preliminarily explored.The results showed that:(1)The adhesive strength was significantly affected in setting plate on potential difference.(2)The good adhesive strength’s potential difference of setting plate was 50～70 V as 10%～12% moisture content of the sakhu veneer with 1.1 mm thickness,PVAc with 16.5% solids content,5.6 Pa·s viscosity at 20 ℃,the double faced spread 300 g/m 2 with liquid state,and cold presser for 3 hours.
