(Summary description)Introduction of plasma surface activation cleaning treatment of glass cover plate: According to the requirements of the glass cover plate production line, plasma surface treatment equipment can be used to treat the products. The optional equipment includes: atmospheric plasma cleaning machine, wide-width linear plasma equipment, etc. The energy of the ions and electrons of the plasma can reach 6 eV or even higher. Its major feature is that the ejected plasma is neutral and has no charge. The surface of the treated material can be activated, cleaned and etched in-line. At atmospheric pressure, the plasma size of each nozzle is: diameter ranging from 15 to 90 mm, and nozzle length ranging from 20 to 30 mm. According to the product size and processing width requirements, the online processing glass cover plate plasma cleaning machine equipment can be flexibly selected. The principle of surface activation and cleaning treatment of glass cover plasma cleaning machine: Plasma is composed of a large number of free electrons and ions, and is an ionized gas that is close to neutrality on a macroscopic scale. It is another aggregation state of matter, that is, plasma state, that is, the fourth state of matter. The electrons in the plasma get energy from the electric field, transform into free high-energy electrons, collide with atoms and molecules in the gas, produce excitation and ionization, and generate excited molecules, while atoms, ions and free radicals are extremely unstable, chemical reactions It has strong properties and is prone to reactions that generally cannot occur, resulting in new compounds or weightlessness of the treated material. During processing, the surface layer is etched, resulting in new properties (eg, weight loss, moisture absorption, deepening, adhesion, etc.); or leading to cross-linking, grafting, and polymerization. Plasmas are very different from ordinary gases in their properties. The temperature of electrons in plasma can reach several thousand to tens of thousands of K, while the temperature of gas is very low, about hundreds of degrees Celsius at room temperature, and the energy of electrons is about a few to a dozen electron volts. This energy is greater than the bond energy of polymer materials (several to dozens of electron volts), and can completely break the chemical bonds of organic molecules, thereby generating new bond energy; however, it is much lower than high-energy rays, only with It is related to the surface of the material, so it does not affect the matrix properties.
