(Summary description)Plasma cleaner surface cleaning Plasma surface processor activation uniformity improvement: The plasma cleaning machine has a wide range of RF low-temperature plasma treatment, and can be designed into various shapes, especially suitable for material surface modification. Through low-temperature plasma surface treatment, many physical and chemical changes will occur on the surface of the material, or etching phenomena (difficult to see with the naked eye), or the introduction of oxygen-containing polar groups, make the material hydrophilic, adhesive, Affinity and sex were improved respectively. After the surface of the plastic has been plasma treated, it can be effectively pretreated to activate its surface and then glued, printed or painted. Similarly, materials such as ceramics and glass can also be plasma treated. Factory oxygen is often used as a plasma treatment process gas, hence the name: oxygen plasma. The atmosphere is called atmospheric plasma. Depending on the type of material that needs to be plasma treated with a plasma cleaner, this effect may only last for minutes or even months. Because the plasma surface treatment technology has the advantages of simple process, convenient operation, fast processing speed, good treatment effect, less environmental pollution and energy saving, it has been widely used in surface modification. Plasma treatment is a surface modification technique that alters the surface properties of materials through electrical discharge. Substances/objects must be combined with printing inks, coatings and binders after surface treatment. Designed to optimize the bonding properties of polymer substrates. The low surface energy of polymer substrates typically results in poor adhesion of inks, glues and coatings, which have higher surface energy. Plasma surface treatment is widely used in plastic film, extrusion, automotive, pharmaceutical and other industries. In order to obtain adhesion, the surface energy of the matrix must be greater than or equal to the material surface energy of the polymer used. In the process of surface treatment of materials, plasma cleaner plasma has the following basic functions: significantly improve wettability, and form active surface; clean dust and oil, finely clean and eliminate static electricity; provide functional surface, through surface coating treatment, improve The surface adhesion ability improves the reliability and durability of surface adhesion; the wettability of the surface helps us distinguish whether it is good or bad; when the surface tension of the liquid phase increases, the surface energy of the solid substrate increases, and its wettability is better. , the smaller the contact angle. Surface energy of solids and the need for polymer surface treatments. Plastic products usually need to be bonded to metal or other plastic products, or just printed on the surface of plastic products. In order to do this work smoothly, the surface of the material must be wetted with mucilage or ink. Corona treatment and plasma treatment techniques are required. Lubrication properties depend on a special property of the surface: surface energy, commonly referred to as surface tension. Surface energy is the same unit of measure as surface tension, expressed in mN/m. The surface energy of solid substrates directly affects the wettability of liquid surfaces. The rationality of its wettability can be verified by measuring the contact angle. The contact angle is the angle between the tangent of the point of contact and the horizontal plane of the solid surface. After treatment with plasma cleaning machine, good surface energy of various polymer plastics, ceramics, glass, PVC, paper or metal can be obtained. This treatment process can improve the surface tension performance of the product, and the plasma surface treatment is more in line with the industrial requirements for coating, bonding and other treatments. In order for the liquid to form a proper bond with the surface of the substrate, the surface energy of the substrate should be kept within the range of the liquid tension of 2-10mN/m. When the droplet is mounted on a smooth solid surface, the droplet spreads to the substrate, and if it is completely wet, the contact angle is almost zero. Conversely, if the wetting is localized, the contact angle is balanced between 0 and 180 degrees
