Have not used epoxy resin potting glue, because of lack of experience, do not know how to deal with it, to know that poor use, may cause the role of epoxy resin potting glue can not play!
1, epoxy resin potting adhesive use steps detailed explanation
Step 1: Before operation, clean the surface of the bonded material and keep the surface of the bonded substrate dry and clean.
Step 2: Epoxy resin potting glue needs to be deployed on site, so pay attention to the classification of glue and configuration volume ratio when deploying, if the mixing is not uniform, it is easy to cause uniform curing problems.
Step 3: Check that after mixing evenly, glue should be filled in time before curing, and calculate the amount of use in advance, do not put the good glue for a long time, because it will not be used next time.
Step 4: Fill the gap that needs to be filled when filling, otherwise it needs to be filled twice
Step 5: During the curing process, keep the operating environment clean. Do not let dust, oil, etc. fall into the glue.
The above is the use of epoxy resin potting glue process, sizing process according to the steps to operate, in the proportion of epoxy resin potting glue pay attention to uniform mixing, of course, the messy environment will also affect the quality of the product.
DIY using epoxy potting glue notice what
2, epoxy resin potting glue use steps:
1. The products to be potting should be kept dry and clean;
2, please check agent A before use, observe whether there is settlement, and stir agent A fully;
3, according to the ratio of the amount, and accurate weighing, please remember that the ratio is A weight ratio rather than a volume ratio, A, B mixture should be fully stirred evenly to avoid incomplete curing;
4, after mixing evenly, please fill glue in time, and try to use the mixed glue within the usable time;
5, after perfusion, the glue will gradually penetrate into the gap of the product, if necessary, please carry out two glue filling;
6, during the curing process, please keep the environment clean to avoid impurities or dust falling into the uncured adhesive surface.
3, epoxy resin potting glue operation common problem analysis:
1, the glue does not cure
Possible causes: the curing agent is put too little or too much (the ratio is very different), the storage time of A glue is long, and the use is not stirred or not stirred evenly.
2, the glue that should be hard glue is soft after curing
Possible causes: The glue ratio is not correct: if the ratio or deviation is not large by weight (more or less curing agent may have this situation), the storage time of A glue is longer, and the glue is not stirred or not stirred evenly before use.
3, some glue curing, some glue is not curing or curing is not complete
Possible causes: uneven mixing, A glue storage time is long, before use is not stirred or not stirred evenly.
4, after curing the glue surface is very uneven or a lot of bubbles
Possible causes: curing too fast, heating curing temperature is too high, close to or exceed the operation time of potting dispensing.
5. The surface of the glue is oily after curing
Possible causes: The glue filling process is watery, too wet, A glue is stored for a long time, and it is not stirred or not stirred evenly before use.
