Ozone is a strong oxidant, which oxidizes the molecules on the plastic surface to produce carbon-based compounds and peroxy compounds. In addition, corona treatment also has the effect of removing oil, moisture and dust. After the above physical and chemical modification, it can significantly improve the pre-determination and adhesion of the plastic surface.
Influences Sectors:
1. The corona discharge is carried out in the air, so the air humidity will affect the degree of treatment. The air humidity is high, and the treatment effect is often not ideal.
2. The degree of corona treatment will subside with prolonged storage time. The speed of fading is related to the environment temperature, material thickness and other factors.
The higher the temperature of the environment, the faster the decay speed. Generally, the corona effect of thicker materials decays faster than the conversion of thinner materials.
After treatment, it is best to use it as soon as possible to get the best wettability and additional power.
