(Summary description)The process of cleaning the glass panel of mobile phone before chemical toughening is very complicated. The non-equilibrium Ar/O2 atmospheric plasma jet generated by the pre-ionization of the needle electrode is a simple cleaning process. The contact Angle between oil and stearic acid on the glass panel was determined with a contact Angle instrument. After 1~2min of plasma jet cleaning, the contact Angle of water was significantly reduced. Scanning electron microscope observation also verified the cleaning effect. In recent years, international famous mobile phones are made of glass as the panel, in order to improve the strength and hardness of the glass panel, chemical toughening is usually used, and before chemical toughening needs to be cleaned, if the cleaning is not good, it will affect the enhancement effect. The traditional cleaning method is to scrub with detergent first, then ultrasonic cleaning with acid solution, alkali solution and organic solvent, which is complicated, time-consuming and easy to cause pollution. Atmospheric pressure low temperature plasma is the rise in recent years, with a variety of cold gas generated by glow discharge plasma, with low breakdown voltage, and metastable molecular ions concentration is higher, electronic high temperature, low temperature neutral molecules, producing plasma even part of the larger, good controllability, do not need to vacuum, can continuous surface cleaning. The higher the concentration of chemical active components in plasma, the better the cleaning effect. Lubricating oil and stearic acid are the most common contamination substances on the glass surface plate of mobile phones. After contamination, the contact Angle of the glass surface to water increases, which affects ion exchange. Traditional cleaning methods are complicated and easy to pollute. Atmospheric pressure plasma cleaning machine generator structure is simple, do not need to vacuum, room temperature can be cleaned, the generated excited oxygen atoms are more active than ordinary oxygen atoms, can be contaminated lubricating oil and stearic acid in the hydrocarbon oxidation, carbon dioxide and water. At the same time, the plasma jet also has mechanical impact force, which plays a role in cleaning, so that the pollutants on the glass surface can be quickly removed from the surface, achieving the purpose of efficient cleaning. Atmospheric pressure plasma cleaning machine features: Optional with a variety of types of plasma nozzle, suitable for different occasions to work, meet a variety of different products and treatment environment; Small plasma equipment, easy to carry; In-line can be installed In the production Line of customer equipment to reduce input cost; Plasma cleaning machine long service life, low maintenance cost.
