Foreign countries have made new achievements in basic research of phenolic resins.
The use of scanning spectroscopes such as RAMINVATANPARAST in Finland to study the curing process of phenolic ressol resin (Resol) using scanning spectroscopy, and to determine the relationship between the molecular structure of the resin and the improvement of the curing characteristics, and thus has practical significance for guiding production.
In the study of JMLAZA et al. in Spain, a thermal scanning metamorphometry method was used to study the curing reaction of phenolic ressol resin from 70-105°C, and the activation energy parameters were determined in detail. The effects of moisture and free phenol on the curing properties were studied. Impact has achieved results.
