glass surface treating corona machine

Currently HeFeng corona adopted the stable, advanced, reliable, imported high power IGBT module, the main components which device control, trigger, display the circuit is composed of integrated circuit block.digital display, make the equipment running very safe and reliable, durable, low failure rate, and with over-voltage overload, over current, short circuit and automatic self-protection, It is thepopualr trend of the corona at home and abroad. Due to the use of power device IGBT, the product structure is compact and the circuit connection is simple reliable, high efficiency, compact ,easy use, one button operation and modular in structure, convenient maintenance and low price.

Corona principle and role

Use high-frequency high-voltage on power pole in the discharge between the rollerand corona, low temperture plasma formed by iionization of air between the ploes to produce ozone,which is a strong oxidizer, can change the molecular structure of plastic surface to make it non-polar into polarity. at the same time after the corona treating, it will cause uneven surface hole roughen,it will enhance surface activity, such as the increase in surface tension, that is , ink,glue,etc,willbe able to further penetrate the materials and processed to achieve the idea effect on the printing and glue application.
