During the production process, many materials are difficult to bond, spray, print, weld, etc. due to the low surface energy. Chemical primers, liquid adhesives, flame treatment, and plasma treatment are all activation methods that can increase surface energy. Among them, chemical primers and liquid adhesives are often highly corrosive and environmentally hazardous, flame treatment is unstable, and the risk factor is high. The plasma cleaning machine has no damage, no pollution, no waste water, meets the requirements of environmental protection, and the process is stable and safe. It is a safe and stable surface activation treatment technology.
1. Activation Principle of Plasma Cleaning Machine
Activation in air or oxygen plasma, the non-polar hydrogen bonds of the plastic polymer are replaced by oxygen bonds, providing free valence electrons to the surface to combine with liquid molecules, thereby improving the "non-adhesive" plastic has a good adhesion And sprayability. In the vacuum plasma, other gases can be used in addition to air and oxygen. These gases can adsorb nitrogen, amines, or carbonyl groups as reactive groups at the position of oxygen. The activity of the surface after treatment by the plasma cleaner is still effective after several weeks and months. However, follow-up processing should be carried out as soon as possible, because as it ages, it will absorb new dirt and lose its activity.

Second, the use of plasma cleaning machine
1 Plasma surface activation / cleaning; 2 Adhesion after plasma treatment; 3 Plasma etching / activation; 4 Plasma degumming; 5 Plasma coating (hydrophilic, hydrophobic); 6 Enhanced bonding; 7 Plasma coating; 8 Plasma ashing And surface modification and other occasions. Through its treatment, it can improve the wetting ability of the material surface, enable a variety of materials to be coated, plated and other operations, enhance adhesion, bonding force, and at the same time remove organic pollutants, oil stains or grease.
3. Products processed by plasma cleaning machine
Metal, PE, PP, PVF2, PVC, PT, LDPE, Teflon and other materials, connectors, wires, glass lenses, automotive shutters and neon lamps, halogen mirror reflector processing, etc.
4. Plasma cleaning machine application field
