Operation process
- Preparation: Put A \ B material original packaging barrels at 60 ℃ environment preservation 2 hours, after take out, compound viscosity is
- Mixing：Withthe A component of the filler will contain the time to precipitate down, so before the use of A component in the original packaging after mixing evenly, and then A, B components by weight ratio of 3: 2 weighing with Ratio, even after mixing can be
- Component B may occur during storage or agglomeration of crystal (a normal case), if required beforeuse crystalline placed in an oven at 80 ℃ to melt it, and then cooled to room temperature and after use, which does not affect its
- Good potting device, if necessary, vacuum may continue to help increase the electrical properties of the
- Curing conditions: 100 ℃ * 2h + 120 ℃ * 2h + 150 ℃ *
The temperature is below 150 ° C and the final curing temperature can be omitted.
