There Are Two Versions Of Inflatable Shafts Commonly Used

working principle:
The inflatable shaft is a special rewinding and unwinding shaft, that is, the shaft that can be expanded after high-pressure inflation, and the surface part of the shaft is quickly retracted after deflation. It is very convenient and fast to use. It only needs the user to prepare the air source. The air pressure is controlled within 6-8 kg. When the paper tube needs to be inflated, the air stick can be inflated against the air nozzle on the inflatable shaft , When you need to unload, you can deflate by pressing the air core on the air nozzle with your hand, and the inflation and deflation can be completed in 2 seconds.

In order to better change the surface energy of the substrate of the inflatable 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 in the production of substrates.

Whether the surface becomes rough after corona treatment, there are currently two versions commonly used.
1. It is easy to absorb printing ink and adhesive, which is denied by scanning electron microscope observation.
2. It is a popular theory recently that corona treatment rearranges the molecular structure on the surface of the substrate.

Inflatable shaft refers to a special winding and unwinding shaft, that is, the shaft that can protrude from the surface (referring to the key strip) after high-pressure inflation, and the shaft of the surface part (referring to the key strip) quickly retracts after deflation. In addition, it can also be called pneumatic shaft, expansion shaft, inflation shaft, inflatable roller, inflatable shaft, pressure shaft, inflatable roller and so on.

Seeing that there are so many names for the inflatable shaft, isn't its working principle very complicated? Don't worry about this, it's called a lot, but their working principles are the same, no other impact. The inflatable shaft and the inflatable sleeve are very convenient and fast to use. You only need to prepare your own air source. The air pressure is controlled within the range of 6-8kg/cm2. When you need to lock the external parts (such as a round paper tube), just inflate The handle can be inflated by facing the air nozzle on the inflatable shaft. The key bar will protrude against the external parts (such as a round paper tube). When you need to relax the paper unloading, press the sliding air on the air nozzle by hand. The core is deflated, the key strip will return to its original appearance, and the external parts (such as the round paper tube) can be taken out.
