The purpose, method, and equipment recommendations for heating the glue before and after the glue filling process
At present, two component adhesives such as epoxy resin and polyurethane can improve curing speed and flowability after heating. Therefore, heat the glue before the glue filling operation.
The purpose of heating the adhesive is:
1. Improve the fluidity of the adhesive;
2. Prepare for heating and curing;
1. Improve the fluidity of adhesive:
Some adhesives have a higher viscosity. Poor liquidity. If the flowing state looks like honey, asphalt, and even more so, toothpaste. At this point, it is very difficult to carry out automated glue filling operations. However, due to the inherent characteristics of a certain part of the glue, its flow performance will improve after heating, making it convenient to carry out glue filling operations. Therefore, a heating function is configured in the glue dispenser to heat the glue.
Another noteworthy point is. Winter is relatively cold in northern regions. Glue may freeze. At this point, the heating function can also be used to thaw the glue. So as to carry out the homework.
