(Summary description)Plasma cleaning machine is the key technology of ultra-fine environmental cleaning, surface activation and plasma coating. Plasma cleaning machine can not only clean and remove dirt, but also improve the surface performance of the material itself. For example, to improve the surface wettability, increase ink, coating, coating adhesion, enhance the material's surface energy, hydrophilic. Adhesiveness refers to the stability of the connection or combination between the substrate and the adhesive coating. The separation force is the standard for bonding performance and is directly applied to the separation force value during bonding (peel test, end force test). Plasma cleaning machine can improve the surface adhesion of materials, is a very environmentally friendly treatment method. If the binding force is higher than the adhesion strength of one of the two bonds, the adhesion performance is better. If the separation of attachment is not caused by the dissolution of the compound but by the fracture of the material in a pair of complexes, then the above situation is corresponding. If the coating material (paint, adhesive) completely wet the substrate, it can achieve good adhesion. Wettability can usually be determined by: Check ink; LABS testing; Contact Angle measurement. No matter what kind of substrate or coating, the basic use of plasma cleaning machine must be pretreated, the purpose is to get enough adhesion, because there are always some factors will affect the adhesion. Preprocessing includes at least one or more of the following sets of steps: Cleaning: especially for the removal of hydrocarbons (mold release agent, oil, grease, etc.), the plasma cleaning machine can be used for processing, can completely remove such substances, so as to improve the surface adhesion. Plasma activation: in order to completely bond the coating, the surface of the substrate must be greater than the surface tension of the coating. The surface energy can be increased by plasma activation, and almost every material combination can achieve complete binding. Increase surface area: A rough (clean, active) surface is much better than a smooth (smooth) surface. Through plasma treatment coarsening, surface roughness (increase surface area) can be realized, so as to realize frosting and sandblasting processing. Corrosion: chemical etching, plasma etching, micro-sandblasting. Oxidation removal: By plasma treatment, the oxide layer on the material surface is also removed.
