Plasma Surface Treatment Machine

Name: Plasma Surface Treatment Machine
Brand: Dongguan Hetair Intelligent Equipment Co., Ltd.
Rating: 4.2 (3 reviews)

Plasma surface treatment is a technology that utilizes plasma (ionized gas) to modify material surfaces. The equipment ionizes gases (such as oxygen, nitrogen, argon, etc.) through a high-voltage electric field, generating highly reactive plasma. This plasma interacts with the material surface through physical or chemical reactions, thereby improving surface wettability, adhesion, cleanliness, or chemical properties.

Core Advantages

In low-temperature plasma, the energy of particles typically ranges from a few to several tens of electron volts (eV), which is higher than the bond energy of polymer materials (a few to several tens of eV). This energy is sufficient to break the chemical bonds of organic macromolecules and form new bonds. However, it is far lower than high-energy radioactive rays, affecting only the material surface without altering the bulk properties.

In non-thermodynamic equilibrium low-temperature plasma, electrons possess high energy, capable of breaking chemical bonds on the material surface and enhancing particle reactivity (greater than thermal plasma), while neutral particles remain near room temperature. These advantages make it suitable for surface modification of heat-sensitive polymer materials.

Through low-temperature plasma surface treatment, the material surface undergoes various physical and chemical changes, such as etching-induced roughness, formation of dense cross-linked layers, or introduction of oxygen-containing polar groups. This improves hydrophilicity, adhesion, dyeability, biocompatibility, and electrical properties. Under appropriate processing conditions, the surface morphology of materials changes significantly, introducing various oxygen-containing functional groups, transforming the surface from non-polar and low-adhesion to polar, adhesive, and hydrophilic—beneficial for bonding, coating, and printing.

Plasma Surface Treatment Generally Delivers the Following Key Effects

Activation

Significantly enhances surface wettability, creating an active surface.

Cleaning

Removes dust and oil, enabling precision cleaning and static elimination.

Coating

Provides functional surfaces through coating treatment, improving adhesion reliability and durability.

After treatment using atmospheric plasma technology, various materials—including polymers, ceramics, glass, PVC, paper, and metals—achieve increased surface energy. This process improves surface tension characteristics, making the materials more suitable for industrial applications such as coating and bonding.
