Manufacturing Technology of Strengthened Poplar Veneers
Three mixed liquids, Styrene, Methylmethacrylate and Vinyl acetate were used to soak poplar veneer to obtain strengthen poplar veneers. The optimal molar ratio was fixed on 1:2:1.Soaking and polymerization technology were obtained as pressure 0.4Mpa, packing time 60 minutes, polymerization temperature 80°C, polymerization time 6 hours, cobalt naphthenate 2%, zinc chloride 6%, and azobisisobutyronitrile 3%. The impact of high temperature on the conversion was significant in the chosen level, other factors on the conversion rate was not significant.
