(Summary description)Plasma cleaning machine cleans polymer plays a role in surface reorganization, cleaning, modification, etc.: Plasma cleaning machine is a brand-new high-tech. Using plasma cleaning machine can achieve effects that cannot be achieved by conventional cleaning methods. Plasma is a state of matter, also called the fourth state. Add enough energy to the gas to make it ionize and become a plasma state. The active components of plasma include: ions, electrons, active radicals, excited states (metastable states) of nuclides, photons, and so on. Plasma cleaners play an extremely important role in cleaning polymers: 1. Reorganization of the polymer surface: The inert gas used in the cleaning process of the plasma cleaner will destroy the chemical bonds on the polymer surface, thereby generating free functional groups on the polymer surface. The free functional groups on the surface of the polymer recombine to form the original polymer structure, and can also be combined with the free functional groups of the adjacent same polymer chain, or with the free functional groups of adjacent different polymer chains. Polymer surface reorganization can increase surface hardness and improve surface resistance. 2. Cleaning the surface of polymer materials: The plasma action bombards the surface of the material with high-energy electrons and ions to mechanically remove the dirt layer. Plasma cleaner cleaning can remove the dirt layer, unwanted polymer surface coating and weak boundary layer that may exist in some processed polymers. 3. Surface modification of polymer: The plasma destroys the chemical bonds on the polymer surface, resulting in the formation of free functional groups on the polymer surface. According to the chemical properties of the plasma process gas, these surface free functional groups combine with atoms or chemical groups in the plasma to form a new polymer functional group, replacing the original surface polymer. Polymer surface modification can change the chemical properties of the material surface without changing the overall properties of the material; 4. Polymer surface coating: Plasma coating is to form a thin plasma film on the surface of the material substrate through the polymerization of the process gas. If the synthesis gas used is composed of composite molecules such as methane, tetrafluoride, carbon, etc., they will break in the plasma state to form free functional monomers, which are connected on the polymer surface and reconstituted into functional monomers, thereby Polymer surface coating. The polymer surface coating can significantly change the permeability and friction properties of the polymer surface.
