Color sealing tape is easy to mark and shield, generally more beige and khaki, in addition, there are common colors of red, green and blue tricolor lamps, can be particularly large, then how to distinguish the color sealing tape is good or bad What?
The easiest way is to pinch a pair of colored sealing tapes and then quickly pull them apart. If you can pull the adhesive off of one side, you can see the purity and transparency of the original film. It is important to look at the thickness of the glue. If no glue is torn or spotted, one of the glues is a lot of impurities and the glue is not sticky. The second is too much water, which has already evaporated. At this time, the initial adhesive force of the tape has dropped so badly that it feels like to distinguish. The color seal is applied to the object, the thicker the glue, the better the shielding performance and the better the quality.
