Describes the plasma surface treatment process equipment

Plasma, the fourth state of matter, is a unique treatment medium used to treat and roughen surfaces. Plasma surface treatment equipment has unique advantages, the characteristics of its interaction with the surface and the scope of application are as follows. Plasma surface treatment equipment has the advantages of surface treatment, flexibility and consistency of process, low cost, easy to use, user and environment safety. Depending on the type of processing gas and material used, the plasmon surfaces interact differently. A variety of plasma treatment gases can be used for the removal, oxidation, activation, crosslinking and deposition of chemical and mechanical pollutants.

Plasma surface treatment

Plasma surface treatment equipment technology

What plasma is, how it is produced and maintained, and how it interacts with surfaces. A large number of ions, excited molecules, free radicals and other active particles in the plasma act on the surface of the solid sample, which can not only remove the original pollutants and impurities on the surface, but also play a corrosive role, making the sample surface rough, forming many small depressions, and increasing the specific surface area of the sample. Improve the wettability of solid surfaces. Plasma forming uses capacitive plates or magnetic induction to generate an RF oscillating electric field in a gas region.

The combination of electric field acceleration of the electron and elastic scattering of neutral atoms or field lines at low enough pressure heats the electron. When electrons in a neutral gas gain kinetic energy beyond the ionization threshold, the neutral collision of electrons leads to further ionization, resulting in the creation of additional free electrons, which are heated in turn.

Plasma surface interactions:

The energy of the electrons and ions in the plasma surface treatment equipment process is sufficient to ionize neutral atoms, separate the molecules, form reactive free radicals, cause the atoms or molecules to produce excited states, and locally heat the surface. Depending on the process gas and process parameters, the plasma can make free radicals react with the surface through mechanical action, the dynamic migration of electrons and ions and the corrosive effect of the surface, as well as the chemical reaction work. In general, plasmas can act on and clean surfaces through several mechanisms: etching, activation, deposition, crosslinking, and grafting plasma surfaces.

Plasma surface treatment equipment advantages:

Effect on the surface of the material: plasma treatment only affects the near surface of the material and has no effect on the blocky properties of the material. Unlike many wet cleaning processes, plasma cleaning does not leave organic residues; Under the right conditions, plasma cleaning can completely remove contaminants, resulting in an "atomically clean" surface. Unlike aqueous solutions, plasmas are not limited by surface tension and can clean rough, porous, or uneven surfaces. Plasma treatment at near ambient temperature can reduce the damage to thermosensitive materials.

Plasma surface treatment equipment process has a certain flexibility and consistency, depending on the process gas and use, plasma treatment can be used for surface characteristics of cleaning, activation, cleaning and modification changes. Plasmas react with a variety of materials, so they can also handle components made of different materials.

1. Low price/easy to use

2, high processing efficiency, short processing time, no drying stage, low energy consumption.

3. Plasma treatment can help avoid process losses due to heat loss and solvent damage.

4, Plasma processing is easier to use and maintain than chemical or mechanical processing, and does not require complex chemical analysis or maintenance.

Plasma treatment usually does not require solvents, nor does it require continuous purchase and processing of solvents.

6. Plasma plasma technology is adopted to improve the safety of users and the environment.

7. Plasma technology can eliminate the safety risk of workers' contact with dangerous chemicals.

8. Plasma plasma treatment is carried out under conditions close to the ambient temperature, which will not cause safety problems.

9, can handle complex geometry of three-dimensional parts.
