What is plasma activated cleaning?

As is well known, low-temperature plasma treatment is used for cleaning and activating surfaces to improve their adhesion properties.

Low temperature plasma cleaning machine can remove trace organic pollutants on the surface, thereby improving the adhesion of the surface. At the same time, plasma cleaning activates the surface, transforming it from a low surface energy state to a high surface energy state, making it easier to bond, improving coating adhesion, and enhancing surface hydrophilicity. The plasma cleaning machine is so powerful that it can help solve the problem of poor adhesion in many industries. Today, I will learn with the editor how plasma cleaning machines perform surface cleaning treatment?

Plasma treatment is used to alter the surface properties of various materials, making them easier to bond, adhere, and paint. By processing the parts, plasma cleaning technology not only cleans but also activates the surface, thereby improving their adhesion.

Plasma cleaning machines often use three states: solid, liquid, and gas. We can move between states by adding or removing energy (such as heating/cooling). If we continue to add enough energy, gas molecules will ionize (lose one or more electrons) and therefore carry a net positive charge. If enough molecules are ionized to affect the overall electrical properties of the gas, it is called plasma.

When exploring plasma cleaning treatment, we will contact many types of plasma cleaning machines, such as atmospheric pressure plasma cleaning machines, online plasma cleaning machines, wide width plasma cleaning machines, multi nozzle plasma cleaning machines, material compatibility, and current processes, which play a key role in determining the most suitable treatment. Let's delve into different types of plasma treatment and explore the equipment that can guide you in choosing the type of treatment that best meets your requirements.

Plasma cleaning technology is a validated, effective, economical, and environmentally safe key surface preparation method. Plasma cleaning equipment can remove residues at the nanoscale. Compared with traditional wet cleaning methods, plasma cleaning machines can reduce organic residues to half, including solvent cleaning residues themselves.

Plasma cleaning produces an original surface, ready for bonding or further processing, without any harmful waste.

The ultraviolet radiation generated in low-temperature plasma effectively breaks most of the organic bonds of surface pollutants, which helps to decompose oil and grease. The energy oxygen species generated in the plasma undergo a second cleaning process. These species react with organic pollutants, mainly forming water and carbon dioxide, which are continuously removed (pumped out) from the chamber during the processing.

If the components for plasma cleaning are composed of easily oxidizable materials, inert gases such as argon or helium can be used instead. Plasma activated atoms and ions act like molecular sandblasting and can decompose organic pollutants. During the processing, these pollutants evaporate again and are discharged from the chamber. The application of plasma cleaning machines in glass products has the characteristics of efficient cleaning, enhanced surface chemical activity, improved optical performance, and a cleaning efficiency of up to 99.9%. It significantly improves the cleanliness of glass surfaces, is environmentally friendly, and has strong applicability.
