Konjac Glucomannan/Chitosan Based Adhesive for Plywood Production
The authors developed an environmentally friendly wood adhesive with good water resistance and low cost using natural konjac glucomannan (KGM) and chitosan as the main ingredients and modified them with sodium hydroxide. Detailed chemical processes with different percentages of each component were presented in the paper. The results showed the bonding strength of plywood samples made with the modified adhesive system using 1% Chitosan,1.5% KGM,and 1% sodium hydroxide produced plywood with the highest dry bonding strength,and the adhesive using 1% Chitosan,1.5% KGM,and 2% sodium hydroxide produced plywood with the best wet bonding strength.
