Features:
Plastic Film Surface Corona Treatment Machine is used for treating material surface and to increases the adhesion of a plastic surface, before printing or laminating/primer coating.
Plastic is a man-made synthetic material, which contains long homogeneous molecular chains that form a strong and uniform product. The chains of molecules are normally joined end to end forming even longer chains, leaving only a few open chain ends, thus providing only a small amount of bonding points at the surface. The small amount of bonding points cause the low adhesion and wettability, which is a problem in converting processes. A high frequency charge would provide both a more efficient end controllable method of increasing the adhesion and wettability of a plastic surface.
During corona discharge treatment, electrons are accelerated into the surface of the plastic causing the long chains to rupture, producing a multiplicity of open ends and free valences are formed.
The ozone from the electrical discharge creates an oxygenation, which in turn forms new carbonyl groups with a higher surface energy. The result is an improvement of the chemical connection (dyn/cm) between the molecules in the plastic and the applied media/liquid. This surface treatment will not reduce or change the strength. Neither will it change the appearance of the material. The Corona only changes the top molecule chains, which is 0.00001 micron thick.
Corona treatment machine is a good surface treatment mathod for UV & Primer coating machine.
The corona treatment can deal with the plastic material such as PE, PET, PP, PVC, BOPP etc.
Corona treatment adopts high voltage fast-switching power transistor for invert circuit
High efficiency, high operating frequency.
Power output is continuous adjustable.
Electronic protection and low speed automatic off.
