The air expansion shaftis a special rewinding and unwinding shaft, that is, the shaft that can be expanded after high-pressure inflation, and the shaft is quickly retracted after deflation. In order to better change the surface energy of the substrate of the air expansion shaft, better printing inks, coating materials and adhesives. The corona treatment we are talking about belongs to post-processing, which means that corona treatment is not the only treatment method that can be used to change the surface energy of the printed matter when the substrate is produced.

 The corona treatment of the air expansion shaftis to change the surface energy of many substrates and make it easy to bond with printing inks, coating materials and adhesives. All substrates have better adhesion characteristics after some treatments during the manufacturing process. Other treatment methods include flame treatment and coating treatment. Which treatment method is used depends on the structure of the substrate?

Many people believe that the corona treatment of the air expansion shaftmakes the surface of the substrate rough, which makes it easy to absorb printing inks and adhesives. However, this view is denied by the observation results obtained by the scanning electron microscope. The theory of the XC differential shaft manufacturer believes that the corona treatment of the air expansion shaftrearranges the molecular structure on the surface of the substrate to produce more polar parts, which is conducive to the attachment of foreign objects.
