Dyne pen introduction
Dyne pen, also known as surface tension test pen, corona treatment pen, and plastic film surface tension test pen. It is a test tool for the corona degree (dyne) of the film surface, which is specially used to measure the effect of the film after corona treatment.
How to use Dyne pen
1. Select an estimated dyne size pen.
2. Draw a straight line (5-10cm) evenly on the surface of the measured object with the Dyne pen.
3. After 2~3 seconds, observe whether the handwriting shrinks and condenses into water droplets. If there are shrinkage drops, change to a dyne pen with a lower value and draw a straight line until there is no shrinkage and no droplet points to determine the surface tension value of the object. If the handwriting is smooth, change to a dyne pen with a higher value and draw again until the handwriting shrinks, then the dyne pen number of the previous value is the dyne value on the surface of the measured object.
Dyne pen result analysis
1. If the drawn lines are evenly distributed without any beads, it means that the surface tension of the film is higher than the index marked on the Dyne pen, and it can be printed in this case.
2. If the drawn line shrinks slowly, it means that the surface tension of the film is slightly lower than the index marked on the Dyne pen. In this case, the printing effect is not good.
3. If the drawn line shrinks immediately and forms bead points, it means that the surface tension of the film is much lower than the index marked by the Dyne pen. This case cannot be printed.
Precautions for using Dyne pen
1) Keep the surface of the measured object clean.
2) Do not stain the dyne pen tip
3 ) Do not draw lines on the same place on the surface of the measured object multiple times
4 ) Store the dyne pen in an environment of 0-25 degrees
5 ) Avoid skin contact with dyne solution
6 ) Use the dyne pen before the expiration date
