How to prevent the encapsulant from drying out or drying slowly? This situation is mainly manifested in that after the encapsulant is cured, it is still soft when pressed by hand, and it has not completely hardened. Next, Shenzhen Tensan will talk about how to avoid the situation where the potting glue is not dry?
1. To prevent the potting glue from drying or slowing down, make sure that the container and stir bar are dry before taking the material. If conditions permit, the container and stir bar can be heated slightly. The measuring instruments must be checked regularly to check whether the proportion of glue is strict and whether the glue is evenly mixed.
2. To prevent the encapsulant from drying out or drying slowly, be sure to use metal, plastic, glass and other smooth-surfaced containers. Remember not to use paper and wooden containers, because the latter materials have large holes on the surfaces. It is easy to bring air and moisture into the resin system, thereby affecting the quality of curing.
3. To prevent the potting glue from drying or slow drying, pay attention to scraping and clearing the bottom of the mixing process to ensure uniform mixing. If possible, glue A and B are mixed well, then pour it into another cup and stir for a while before pouring into the product.
4. To prevent the potting glue from drying or slowing, in order to ensure uniform mixing, the recommended mixing time is 10-15 minutes when mixing by hand. At the same time, pay attention to the mixing strength and stirring in the same direction, try not to bring the air into the encapsulant.
5. To prevent the potting glue from drying or slowing down, accelerate the curing speed according to the proportion of the potting glue. For example, for 1:1 addition molding potting glue, it can be cured by heating, for the mixing ratio 100:10 condensation type potting compound can shorten the curing time by increasing the air humidity and air circulation speed of the sizing environment. This is because the potting glue must be fully cured before it can realize its use value.
