As is well known, plasma cleaning equipment has the advantages of short washing time, fast speed, simple operation, and easy control, and has been widely used for surface pre-treatment of polymer, automotive parts, metal and other surface composites and pre bonding. Materials cleaned by low-temperature plasma require immediate printing, painting, bonding, and composite treatment after cleaning. As the temperature increases, the cleaning time, distance, speed, printing performance, and bonding strength improve over time. In practical work, measures such as heat treatment can be taken to improve the effectiveness, thereby enhancing the hydrophilicity of the glass surface and removing micro pollutants.

Why is plasma cleaning equipment used on glass surfaces? The specific reasons are as follows:

1. During the production, processing, storage, and transportation of glass, impurities such as dust, oil, stains, and organic pollutants are easily adsorbed on the surface. Plasma cleaning equipment uses the active species generated by plasma, such as electrons, positive ions, and reactive oxygen species, to physically and chemically react with the pollutants on the glass surface, decomposing them into harmless substances such as carbon dioxide and water, thus achieving efficient cleaning with a cleaning efficiency of up to 99.9%. The plasma cleaning machine can clean surface impurities.

2. The main component of glass is silicon dioxide, which has a relatively inert surface. Plasma bombardment of the glass surface can break the existing chemical bonds on the surface. Free radicals in the plasma form a network cross-linking structure with these bonds, introducing functional groups such as alkyl, amino, carboxyl, etc. on the glass surface. These functional groups are all active groups, and plasma cleaning can greatly activate the surface activity of the glass, making the glass surface change from inert to highly chemically active.

3.In processes such as glass coating and cleaning, it is necessary to firmly adhere the coating to the glass surface. Plasma cleaning equipment can form a micro rough surface on the treated glass surface, which can improve surface activity and facilitate better bonding between the coating material and the glass surface. This significantly enhances the adhesion and durability of the coating, effectively solving problems such as weak coating and paint adhesion, and paint peeling.

4.Glass is commonly used in the field of optics, such as optical lenses, displays, etc. Plasma cleaning equipment can remove small defects and pollutants on the surface of glass, reduce scattering and absorption of optical materials, improve their transparency and optical performance, and make glass products perform better in optical applications.

5. After treatment with a plasma cleaning machine, hydroxyl functional groups can be injected into the glass surface, reducing the water contact angle of the glass surface and changing it from a hydrophobic state to a hydrophilic state, thereby improving the wettability of the glass surface. This is very important in some applications that require good contact between the glass surface and the liquid.

6. Plasma cleaning is a gentle cleaning method that does not cause mechanical damage, scratches, or other physical damage to the glass surface during the cleaning process, ensuring the integrity and original properties of the glass surface. It is particularly important for high-precision and high-value glass products.

7. Plasma forms an extremely thin oxide layer on the surface of glass, enhancing the surface chemical activity and helping to improve the adhesion and corrosion resistance of coatings. Plasma can also form small protrusions and depressions on the glass surface, increasing the surface area and thus improving the adhesion and wear resistance of coatings.

The seismograph linear plasma cleaning machine is now widely used for surface treatment in industries such as PCB materials, glass, ITO, etc. It is processed under low temperature and low pressure conditions to ensure the service life and performance of the equipment. Plasma cleaning equipment can achieve online processing.
