摘要：
The curing of a phenol-formaldehyde-tannin (PFT) adhesive in the presence of pine or eucalyptus wood has been studied using differential scanning calorimetry. The influence of the adhesive/wood ratio on the activation energy (E-a), the temperature of the maximum of the exothermic peak (T-p) and the enthalpy of the curing process (Delta H) was analysed. E-a, T-p and Delta H of the curing reaction decreased when wood was added in the curing system. The adhesive/wood interaction did not depend significantly on wood species.
