In practice, all kinds of roll products are prone to glue chipping during use. For example, polyurethane roller, during the rolling process, the glue surface is often damaged with the crack of ink film, and then chipped. So, what is the reason for this phenomenon?

1. Excessive pressure regulation of polyurethane roller during rolling may cause chipping on the roller surface if the protection measures are improper or untimely during idling of the machine.

2. Too high temperature in the process of polyurethane roller machining will cause carbonization on the surface. If the printing time is short, the block will fall off.

3. If the ink used is dry fast and the ink roller is not cleaned as required, it is easy to dry for a long time.

The above is the introduction to the causes of the glue chipping of polyurethane roller. In general, it is caused by the improper operation of the staff. It requires that the staff must understand and master the operation methods of the glue roller in detail before using the glue roller.
