New achievements have been made in the basic research of phenolic resin
foreign countries have made new achievements in the basic research of phenolic resin
raminvatanparast of Finland and others used scanning spectroscope to study and measure the curing process of resol resin through the change of fluorescence intensity, and determined the relationship between the molecular structure of the resin and improving the curing characteristics, which is of practical significance for guiding production Spain Za and other researchers used the thermal scanning method to study the curing reaction of resol resin in the yield state, which is a phenomenon from ℃ and other temperatures. The activation energy parameters were measured in detail, and the effects of water and free phenol on the curing characteristics were studied, and the results were achieved this article comes from the network, and the copyright belongs to the original author.
