Plasma pretreatment of glass cover plate before coating

Plasma pretreatment of glass cover plate before coating

In the manufacturing process of mobile phones, residual organic pollutants such as oil, wax, fingerprint, and grease are often found on the surface of optical materials such as glass cover plates, mobile phone cover plates, and display screens. The existence of these residual pollutants is not conducive to coating, spraying, printing, bonding, welding, and other processes. Therefore, these pollutants need to be cleaned before the next process to ensure the quality of the subsequent process.

Glass cover plate coating, also known as glass cover plate spraying and coating, is applied in the 5G industry, covering mobile phone cover plate coating, glass cover plate coating, display screen coating, protective sheet coating, optical material coating, etc. Glass cover plate coating can make the glass cover plate and backplane more beautiful, but also play a fingerprint resistance, glare resistance, UV resistance, acid and alkali resistance, oxidation resistance.

Plasma pretreatment is plasma surface treatment machine (generally for low-temperature atmospheric pressure plasma surface treatment machine rotating nozzle) in AF, AS, AG, AR coating (spraying) technology, fine cleaning, etching, and was carried out on the substrate surface activation, can get a very thin coating on the surface of high tension, is advantageous to the spraying potions to firm and uniform thickness.

Plasma cleaning technology has the following advantages in processing:

(1) Environmental protection and energy saving. Compared with the traditional wet cleaning technology, plasma cleaning technology belongs to the dry process, does not consume water and chemical reagents, energy saving, no pollution

(2) With online production capacity, can realize full automatic processing, the processing time is short, high efficiency, low cost

(3) Regardless of the type of substrate, can be processed, can deal with the shape of more complex materials, material surface treatment uniformity is good

(4) The effect on the surface of the material only involves nano-level processing, which can give it another new function while maintaining the original special effect of the treated material

(5) Low processing temperature, no damage to the surface of the material, especially suitable for processing polymer materials
