Plasma cleaner application mode

1 plasma cleaning

Conventional cleaning methods can not completely remove the surface film of the material, but will leave a thin layer of impurities, and a typical example of this kind of solvent cleaning.

Plasma cleaning machine is the material surface by plasma bombardment, and gently wipe the surface completely.

Plasma cleaning to remove invisible film, slight rust and other outdoor exposure, etc. As the user touches the kind of dirt on the surface, and that plasma cleaning does not leave residues on the surface.

Plasma cleaning machines to handle many types of materials include: plastic, metal, glass, connectors, ceramics, and other specialty materials, and the geometric shapes of the surfaces.

The best plasma cleaner is that it can not only cleansed surface dirt, but also enhance the adhesion properties of the material surface.

2 Polymer Cleaning

Cleaning the surface of the polymer ①

Ablation plasma by high energy electron and ion bombardment of the surface of the material, mechanically remove dirt floor.

Plasma surface cleaning can be removed may be present in certain processed dirt polymer layer surface of the polymer coating and not the weak boundary layer

② recombinant surface of the polymer

Ablation plasma in the inert gas of the chemical destruction of the polymer surface resulting in the surface free functional groups of the polymer formation.

Free functional groups of the polymer surface to bond re-formation of the original polymer structure, but also with the same polymer chain functional group adjacent to the free bond, or a different polymer chains in the vicinity of the free functional groups on a chain.

Polymer surface restructuring can improve the surface hardness and chemical resistance.

③ Polymer surface modification

Plasma ablation destroyed bonds of the polymer surface, resulting in surface free functional groups of the polymer formation.

Process gas plasma-based chemical nature of these functional groups and the surface free plasma or chemical group of atoms to form a new polymer functional groups, instead of the old surface polymer functional groups.

Polymer surface modification can change the chemical properties of the material surface, does not change the nature of the material as a whole.

④ surface of the polymer coating

Plasma coating process gas through the polymerization of the base surface of the material to form a thin plasma coating.

If the process gas to be used by the compound molecules, for example: methane, four fluoride, carbon, then they will be broken in a plasma state, a functional monomer to form a free, these functional monomers in the polymer surface and the re-bonding compound the polymer surface coating.

The polymer coating can significantly change the surface friction of the permeability and.

⒊ biological materials

①. Disinfection, sterilization:

Plasma sterilization, sterilization of medical devices have been on many recognized.

Plasma treatment in the medical instrument cleaning and disinfection of synchronization has great potential.

Plasma Sterilization particularly suitable for high temperature, chemical substances, radiation, allergies or dental implants medical appliances and equipment cleaning.

②. Improved adhesion

Many biological materials, low energy surface of the medium, making it difficult to effectively carry out adhesion and coating.

Plasma surface activation leads to the formation of surface functional groups, these functional groups to enhance biological material surface energy and improve the interface adhesion.

③. Invasive

Most untreated biological material has a weak wettability (hydrophilicity).

Plasma surface treatment may increase or decrease the number of different biological materials hydrophilicity.

Make the surface activation by plasma hydrophilic by plasma coating, make the surface hydrophobic.

④. Layer of low friction and obstruction

Some materials of the ester and high coefficient of friction surface of the polymer, such as polyurethane.

Plasma coating with a small coefficient of friction, the surface becomes more smooth biological material.

Plasma coating can form a dense barrier layer, to reduce the liquid or gas permeability of the biological material.
