Glued Mechanism of PF Resin Adhesive From Modified Base-treated Liquid of Masson Pine Bark
Huang Ruzhu Lin Qiaojia(Forestry Department of Fujian College of Forestry,Nanping 353001)
Chemical composition of Masson pine bark and the samples of modified base-treated liquid collected from each link in the production chain were analysed to probe into the glued mechanism of PF resin adhesive.Polyphenols and PF resins in the modified base-treated liquid of Masson pine bark were polycondensed to linear polymers which were further solidified to the insoluble and non-melted resin through ho-pressing.
