Features
The Sheet Corona Treater effectively increases material surface tension through its discharge process. During corona discharge, high-energy particles impact the molecules on the material's surface, causing molecular chains to break and rearrange, thereby generating polar groups such as hydroxyl and carboxyl. These polar groups act as points of attraction, significantly enhancing the surface's adsorption capacity. Utilizing a Sheet Corona Treater in the printing process allows ink to adhere more closely, avoiding problems like blurred patterns and de-inking. During coating operations, it ensures the coating spreads evenly and adheres firmly, preventing peeling or bubbling. In bonding processes, it enables adhesives to fully combine with the material surface for stronger bonds. Compared with untreated materials, processing with a Sheet Corona Treater fundamentally solves processing issues caused by insufficient surface tension in traditional materials.
Advantages
The operational stability of the Sheet Corona Treater is a key advantage. When building these machines, we utilize only high-quality, industry-branded components. These parts endure significant heat, wear, and interference, functioning reliably in demanding, continuous environments. An advanced circuit design maintains stable parameters like current and voltage during operation, minimizing performance fluctuations. This combination of premium setup and scientific design allows the equipment to operate trouble-free for extended periods. The Sheet Corona Treater boasts a long mean time between failures, enabling prolonged, steady operation. This reliability keeps production lines running smoothly, ensures on-time deliveries, and protects customer relationships by preventing downtime. It also reduces maintenance and part replacement costs, minimizes raw material waste, simplifies production planning, and supports firm growth. Investing in a Sheet Corona Treater delivers long-term operational and economic benefits.
Usage scenario
In printing book covers, applying a Sheet Corona Treater to paper or plastic materials increases printing quality. This treatment makes cover patterns more colourful, text clearer, and enhances the book's durability. The electronic control sections of corona machines are usually consistent, but their structures differ based on the processed object's shape.
FAQ
Q: How to set the processing parameters of the corona machine?
A: According to the material type, thickness, and processing requirements, refer to the parameter recommendations in the equipment manual, and set and debug through the touch screen.
Q: Is the corona machine suitable for all materials?
A: No, it is mainly applicable to plastics, films, paper, metal foils, etc. Some materials with strong conductivity or easy to be punctured are not applicable.
Q: Will corona treatment change the intrinsic properties of the material?
A: No, it only acts on a very thin layer (a few nanometers to tens of nanometers) on the surface of the material, and does not affect the mechanical, chemical and other intrinsic properties of the material itself.
