Cleverly use plasma cleaning machine for surface cleaning and activation treatment!

Firstly, we will review the basic knowledge of plasma cleaning machine and explore how it is used for cleaning and surface activation treatment,

What is plasma?

Plasma cleaning technology is an ionized low-temperature, atmospheric pressure gas, which is the fourth state of matter - solid, liquid, and gas are the other two states of matter. When energy is applied to matter, its form may change. Applying heat to a solid can convert it into a liquid, heating a liquid can convert it into a gas, adding energy to a gas can convert it into plasma, and using plasma treatment to activate the surface can remove specific pollutants from the surface and perform material surface activation treatment.

What is the gas of atmospheric plasma cleaning machine?

The gases commonly used in atmospheric plasma cleaning machines include argon, oxygen, nitrogen, etc. Different gases have different functions. The principle is to generate plasma through gas discharge, and use the interaction between plasma and object surface to achieve cleaning, activation, and other purposes. Atmospheric plasma cleaning technology can be applied to the surface through nozzles to guide the flow of flowing gas to the surface. Atmospheric plasma treatment is very suitable for continuous processing applications and can be easily integrated into production lines.

Atmospheric plasma cleaning equipment is highly suitable for handling parts with complex shapes and challenging geometric structures, thereby improving the ability of components to achieve effective bonding, coating, sealing, painting, or printing,

Plasma cleaning and activation technology can generate plasma that interacts with the surface of an object. Firstly, the ions in the plasma are accelerated under the action of an electric field, bombarding the surface of the object with high energy and physically impacting the pollutants on the surface; Secondly, the active particles in the plasma undergo chemical reactions with the substances on the surface of the object, converting pollutants into volatile substances for removal. 

At the same time, after the plasma interacts with the surface of the object, some polar groups are introduced on the surface, thereby improving the surface activity and wettability, achieving the purpose of activating the surface.

Nowadays, with the continuous deepening of plasma cleaning technology, plasma cleaning machines can be widely used in aerospace, automotive, 3C electronics, packaging printing, medical equipment and other fields. By combining different materials to manufacture, when plasma is applied to the surface, the energy applied to the surface can activate the product surface, greatly enhancing the adhesion of paint, coatings and adhesives on the surface.
