This phenomenon is likely to be caused by improper operation when using the polyurethane rubber roller. Next, Huitian New Materials will talk to you about the reasons why the polyurethane rubber rollers have colloidal blockage?
1. The pressure of the polyurethane rubber roller is adjusted too much during the rolling process. If the protection measures are not appropriate or timely when the machine is idling, it will cause the surface of the roller body to fall off;
2. The temperature is too high during the processing of the roller, and the surface is prone to carbonization. If the printing time is short, the phenomenon of block loss will occur;
3. If the ink used has a faster dryness, and the ink roller is not cleaned as required, if it is used for a long time, it will be prone to drying.
Once the polyurethane rubber roller has colloid falling during the rolling process, the user should replace the new rubber roller in time to avoid printing failure.
