(Summary description)In the production process, many materials due to low surface energy, it is difficult to bond, spraying, printing, welding and other processing. Chemical primers, liquid binders, flame treatments, and plasma treatments are all activation methods that increase surface energy. Among them, chemical primer and liquid adhesive often have high corrosive and environmental hazards, flame treatment instability, high risk coefficient. And the plasma cleaning machine treatment of no damage, no pollution, no waste water, in line with environmental requirements, process stability and safety, is a safe and stable surface activation treatment technology. The following is mainly about the activation of plasma cleaning machine 1. Activation principle of plasma cleaning machine: Activated in an air or oxygen plasma, the nonpolar hydrogen bonds of the plastic polymers are replaced by oxygen bonds, providing free valence electrons on the surface to bond with liquid molecules, thus improving the adhesiveness and sprayability of the "unbonded" plastics. In a vacuum plasma, gases other than air and oxygen can be used, and these gases can adsorb nitrogen, amine or carbonyl groups as reactive groups in the position of oxygen. The activity of the surface treated by the plasma cleaning machine remains effective 2-24 hours later. However, follow-up processing should be carried out as soon as possible, because with continuous aging, new dirt will be absorbed and activity will be lost. 2. Use of plasma cleaning machine: (1) Plasma surface activation/cleaning; (2) Bonding after plasma treatment; (3) Plasma etching/activation; (4) Plasma degumming; (5) Plasma plating (hydrophilic and hydrophobic); (6) Enhancing the state character; (7) Plasma coating; (8) Plasma-ashing and surface modification. Through its treatment, can improve the material surface wetting ability, so that a variety of materials can coating, plating and other operations, enhance the adhesion, bonding strength, while removing organic pollutants, oil or grease. 3. Products processed by plasma cleaning function: Metal, PE, PP, PVF2, PVC, PT, LDPE, teflon and other materials, connectors, wires, glass lenses, car blinds and neon, halogen sky lamp reflector processing, etc 4. Plasma cleaning machine Application Field: Metal - remove grease, grease and other organic matter and oxide layer on the metal surface; Automobile manufacturing - used for plastics and spray painting in automobile manufacturing process; Textile production - for hydrophilic, hydrophobic and surface modification of textiles, strainers and films; Biomedicine -- Culture dishes to improve the activity, blood vessel stents, syringes, catheters and various materials to moisten, intersex coating pretreatment; Aerospace - surface coating treatment of insulating materials, electronic components, etc. Electronics - cleaning and etching of circuit boards. Film, PP and other materials without oxidation and activation treatment, improve the weldability; Semiconductor industry - wafer processing and processing removal of photoresist, pre-treatment before packaging; Pretreatment before CLEANING and packaging of LED-support; Plastic rubber - improves the surface activity of PS, PE, PTFE, TPE, POM, AS and PP to facilitate bonding and printing.
