Phenolic resin process

Phenolic resin production process control

Phenolic resin generated by reaction of phenol and formaldehyde.
JiaJie by excessive reaction with phenol formaldehyde resin was obtained.And novolak resin is made from modified phenol with an acid catalyst.

Novolak resin

Traditionally, novolak technology is fused phenol in the reactor, and then join the precise amounts of acid catalyst.The reaction of formaldehyde and phenol under the specified conditions of temperature and time, because the content of free phenol determines the performance of the resin, so the need for careful monitoring of the final phenol resin content.

JiaJie phenolic resin

In JiaJie phenolic resin process, phenol and formaldehyde solution in certain proportion to join at the same time.After the reaction, once the desired destination, then you need to response in a container material cools and refrigerated storage.

Visa, K - PATENTS ® online refractometer can provide online instructions, to track the reaction progress, usually contains enrichment and followed by cooling process.In both of these applications, the refractometer for continuous measurement, by monitoring the degree of reaction, tracking process and determine the reaction end point, provide valuable real-time information for process control.

Read the application instructions, detailed understanding of phenolic resin production process.
