Low temperature treatment
The CoronaTreatment on Aluminum Foil discharge method is mostly based on electric fields with a high frequency and voltage. Instead of being turned into heat energy, the energy is mostly used to speed up the polar reaction of the molecules on the surface of the material. During the whole cleaning process, not much heat is made, and the material's surface temperature doesn't really rise. For heat-sensitive materials, low temperature properties are very important, and the CoronaTreatment on Aluminum Foil excels in this regard. When working with polyethylene film, polyvinyl chloride heat shrink film, and other similar materials, heat can easily distort, melt, or make them less effective. Corona treatment can fully activate their surfaces without changing their shape or other qualities that make them unique. Even things that are very sensitive to temperature, like aluminum-plastic composite films used to package chocolate and low-temperature sterilization packaging materials used in medicine, can keep their original safety, flexibility, and ability to seal after being treated, so they can be fully processed and used again, a key benefit of the CoronaTreatment on Aluminum Foil. It stops problems like material aging and discoloration that come from high temperatures. This means that the treated materials will keep looking good and working well, and corona machines can be used in more areas that have strict standards for material quality.
Uniform treatment
CoronaTreatment on Aluminum Foil achieves all-round uniform treatment of the material surface through carefully designed electrode arrangement and discharge mode. The electrodes are arranged symmetrically, with an adjustable discharge gap, to ensure that every inch of the surface is subjected to the same intensity of corona when the material passes through. Whether it is the edge and center of a wide film or the concave and convex parts of a special-shaped material, a consistent surface activation effect can be obtained. When processing large-format plastic sheets, there will be no excessive processing in the middle and insufficient processing at the edges; when processing paper with textures, the concave parts of the textures can also obtain the same surface tension increase as the flat parts. It allows subsequent printing, coating and other processes to proceed stably, avoiding quality defects such as pattern shedding and coating blistering caused by poor local processing, and improving the overall qualification rate and consistency of the product.
Automobile tire label lamination
Treat the surface of automobile tires so that the tire labels can be firmly attached, making it easier for consumers to check the specifications, production date and other information of the tires.
FAQ
Q: When changing different materials, does CoronaTreatment on Aluminum Foil need to be re-debugged?
A: Yes, the optimal processing parameters for different materials are different, and parameters such as energy and speed need to be reset.
Q: How to judge whether the corona treatment effect is up to standard?
A: You can use a surface tension test pen to test the surface tension value, or conduct small sample tests such as printing and bonding to determine the adhesion.
Q: Can CoronaTreatment on Aluminum Foil run continuously for 24 hours?
A: High-quality equipment can run continuously, but it is recommended to stop and check regularly to avoid long-term high-load operation that affects the lifespan.
