Surface corona pen

The surface corona pen generates a corona through discharge at the tip, polarizing surface molecules of the material to form active groups. It is used to detect the surface tension of materials such as plastics and films, and to determine the adhesion for printing or coating. During operation, lines are drawn on the material surface, and the continuity of ink spreading is observed to evaluate the treatment effect.
Selection
When selecting a surface corona pens, ensure compatibility with the material type and surface tension range to be tested. Consider the stability of the discharge voltage and the compatibility of the ink formulation. Check the wear resistance of the pen tip material and the portability of the power source. Refer to industry-standard testing methods to ensure measurement results align with production line process requirements.
