For engineers who are just entering the industry, if you need to use plasma equipment for processing in terms of process, you should keep in mind the following functions, and then set the corresponding parameters for your own products. There are several functions of Guoxing Technology's plasma equipment. I don’t know, today I will explain to you from the following four aspects, hoping to help you: Plasma surface treatment purification effect It can effectively remove organic pollutants and oxides on the surface of objects. Main features: Any wet cleaning method will leave residues on the surface. Only low-temperature plasma surface treatment can achieve a thorough purification and obtain an ultra-high clean surface. The low-temperature plasma only affects the surface of the material at the nanometer level. It will change the original characteristics of the material, and it is being widely used instead of wet treatment in processes that require high surface cleanliness. Treatment mechanism: It mainly relies on the "activation" of the active particles in the plasma to achieve the purpose of removing stains on the surface of the object. The gas is excited into a plasma state; heavy particles hit the solid surface; electrons and active groups react with the solid surface to resolve into a new gas phase substance and leave the surface. The biggest feature of plasma cleaning technology is that regardless of the type of substrate to be processed, it can be processed. It can treat metals, semiconductors, oxides and most polymer materials, such as polypropylene, polyester, polyimide, and polychloride. Ethane, epoxy, and even polytetrafluoroethylene can be handled well, and can be used to clean the whole, part, and complex structures. Plasma surface treatment activation After low-temperature plasma treatment, the surface of the object will form C=O carbonyl (Carbonyl) and -COOH carboxyl groups (Carboxyl) and -OH hydroxyl (Hydroxyl) three groups. It has a stable hydrophilic function and has a positive effect on bonding and coating. Main features: It can make some active atoms, free radicals and unsaturated bonds appear on the polymer surface. These active groups react with active particles in the plasma to form new active groups, thereby increasing surface energy and changing the chemical properties of the surface , To enhance surface adhesion, adhesion, tension, including the treatment of rubber, composite materials, glass, cloth, metal, etc., involving all walks of life. Plasma surface treatment roughening and etching Corresponding to different materials, use the corresponding gas combination to form a strong etching gas-phase plasma and chemical reaction and physical impact with the body of the material surface, so that the solid material on the surface of the material body is vaporized to generate gases such as CO, CO2, H2O, etc. , So as to achieve the purpose of micro-etching. Main features: uniform etching without changing the characteristics of the material matrix; it can effectively roughen the surface of the material and accurately control the amount of microetching. Plasma surface treatment coating (deposition, grafting) function The plasma treatment process can also be applied to the micro-coating of materials. Optional two corresponding different gases enter the plasma reaction chamber at the same time. The two gases are excited and re-polymerized in the plasma environment, which will produce new compounds and deposit on the surface of the material to form a new coating. Plasma treatment is used With this special effect, materials that are not easy to coat can be applied to the surface of objects, such as anti-blood coagulation coatings for heart stents and artificial blood vessels, scratch-resistant surfaces and hydrophobic coatings for materials. Main features: The molecular chain on the surface of the material can be broken to produce new free radicals, double bonds and other active groups, followed by cross-linking, grafting and other reactions. The active gas will polymerize on the surface of the material to produce a layer of deposition to reach the material. The purpose of surface modification. Under the guidance of the government's industrial policy, Yangzhou Guoxing Technology was registered and established in Yangzhou Jiangdu in 2019.
