Insulator core rod temperature environment
- Aug 06, 2018 -

The insulator core rod is made of epoxy resin and glass fiber main raw materials plus other additives. The production speed of the mandrel is limited due to the characteristics of the epoxy resin.

The curing temperature and time of epoxy resin are not proportional, for example: CYD-128, epoxy equivalent 184~194g/mol, latent curing agent. The curing time of the curing system at 60, 80, 100 and 120 ° C is 3.5 h, respectively.

At 42 min, 18 min and 10 min, the low temperature activity and high temperature activity of the curing system varied greatly. Choosing the right curing agent increases the production rate at lower temperatures.
