I. The Physical Mechanism of the Corona Phenomenon
The corona phenomenon occurs when the electric field strength in the air reaches a certain level, causing the molecules and atoms in the air to ionize, producing free electrons and positive ions, and forming an ionosphere. This phenomenon is particularly pronounced near high-voltage electrodes and is known as the corona phenomenon. In the corona phenomenon, the stronger the electric field strength, the more likely corona discharge occurs.
II. How Corona Treatment Pens Work
Corona treatment pens can be used to write using the corona phenomenon. The basic principle is that high voltage causes the ionization of air molecules, creating an ionosphere and thus generating corona. Driven by the electrodes, the ions in the air migrate, forming ionization trails, which leave visible marks on insulating materials. This creates the writing effect. The working principle of corona treatment pens is simple, but they require a high-voltage power supply and a high-frequency generator to generate high voltage and high-frequency signals, which presents a certain technical difficulty.
III. Applications of Corona Treatment Pens
Corona treatment pens are primarily used in applications such as billboards, signs, and advertising embellishments. They are commonly used to create various fluorescent signs, road signs, and streamer signs. When creating these items, corona treatment pens can be used to create text, outlines, and color drawings. Furthermore, corona treatment pens can create specific pattern effects, such as metallic lines.
IV. FAQ
1. What is the voltage of a corona treatment pen?
The voltage of a corona treatment pen generally needs to be between several thousand and tens of thousands of volts to achieve a writing effect.
2. What is the difference between a corona treatment pen and a laser pen?
A corona treatment pen uses corona discharge to create a mark on the work surface, while a laser pen uses a laser to engrave a pattern or text on the work surface.
3. What materials can a corona treatment pen write on?
Corona treatment pens can write on most materials, such as plastic, metal, and glass.
In summary, corona treatment pens work by ionizing air molecules to create visible marks. They are used for advertising embellishments, logo creation, and other applications. Although the technology is relatively difficult to create, the application range of corona treatment pens will continue to expand with continuous technological advancement.
