Principles of Plasma Cleaning

1. Etching on the Material Surface - Physical Effect

The large number of ions, excited molecules, free radicals and other active particles in the plasma act on the surface of solid samples, not only removing the original pollutants and impurities on the surface, but also producing etching effects, making the sample surface rough, forming many fine pits, and increasing the specific surface area of ​​the sample. Improve the wetting properties of the solid surface.

2. Activate bond energy and cross-linking

The particle energy in the plasma is 0~20eV, while most of the bond energies in the polymer are 0~10eV. Therefore, after the plasma acts on the solid surface, the original chemical bonds on the solid surface can be broken, and the free radicals in the plasma form a network cross-linking structure with these bonds, which greatly activates the surface activity.

3. Formation of new functional groups - chemical reaction

If reactive gas is introduced into the discharge gas, complex chemical reactions will occur on the surface of the activated material, introducing new functional groups, such as hydrocarbon groups, amino groups, carboxyl groups, etc. These functional groups are active groups and can significantly increase the surface activity of the material.

Advantages of low-temperature plasma cleaning

Plasma cleaning, as an important material surface modification method, has been widely used in many fields.

Compared with some traditional cleaning methods, such as ultrasonic cleaning, UV cleaning, etc., it has the following advantages:

1. Low processing temperature

The processing temperature can be as low as 80℃, 50℃ or below. The low processing temperature can ensure that there is no thermal impact on the sample surface.

2. No pollution during the entire treatment process

The plasma cleaning machine itself is a very environmentally friendly equipment, which does not produce any pollution, and the treatment process does not produce any pollution.

It can be matched with the original production line to achieve fully automatic online production and save labor costs.

3. Stable treatment effect

The treatment effect of plasma cleaning is very uniform and stable, and the effect is maintained for a long time after conventional sample treatment.

4. It can be perfectly matched with the automated assembly line to improve production efficiency

According to the user's on-site needs, the optimal assembly line production plan is configured to greatly improve production efficiency.
