The role of plasma processor on mobile phone:
In order to make the appearance of mobile phones more sophisticated, mobile phone cases are usually glued together or printed with brand logos or decorative strips. The previous mobile phone shell is composed of ABS, its surface tension is high, generally do not need to deal with.
But with the wide use of PC, nylon + fiberglass and other materials, no treatment can no longer increase the surface tension of the substrate to the required value of glue.
Atmospheric plasma processor can improve the adhesion on the surface of mobile phone case. By removing organic pollutants and intervening polar organic functional groups on the surface, it can improve the surface hydrophilicity and surface wettability.
A clean surface and surface wettability are critical to a strong bond between two surfaces. The degree of wettability of the surface depends on the surface condition of the plastic itself and all the adhesive materials of the plastic, which is also related to the shell materials of the mobile phone, glue, etc.
The high efficiency of the low temperature plasma can increase the surface tension of the materials to be bonded to the required value of the glue.
