Release time:
2022-07-14
PVD coating equipment uses vacuum evaporation coating method to coat a layer of nanochemical material on the outer surface of the glass, which greatly reduces the surface tension of the glass, reducing the contact area between dust and the glass surface by more than 90%.
PVD Coating Equipment What are its advantages?
PVD coating equipment uses vacuum evaporation coating method to coat a layer of nanochemical material on the outer surface of the glass, which greatly reduces the surface tension of the glass, reducing the contact area between dust and the glass surface by more than 90%.
What are the advantages of PVD coating equipment?
1. PVD coating equipment uses original imported nano nozzles. The nozzles adopt high and low pressure conversion atomization design, making the liquid molecules fine and not affecting the effect of the medicine.
2. The constant current control system ensures a stable and constant supply of the medicine, rather than a wavy supply, solving the problem of white fog.
3. Control the spraying dosage, improve the atomization ability of the medicine, make the film and glass combine evenly, improve the uniformity of product spraying, and increase the smoothness of the film surface.
4. The nozzle moving speed and conveying line speed of PVD coating equipment are adjustable, which greatly improves production efficiency and meets the needs of various users.
5. The theoretical design capacity is 3000-4000 pieces/hour.
6. Using double plasma treatment, cleaning the workpiece before coating, reducing the impurities attached to the workpiece itself, making the glass surface react with the film, improving the firmness of the film bonding, improving the anti-aging and abrasion resistance of the product, and making the coating quality higher.
(1) Surface cleaning: For C, O dirt (organic matter), atmospheric plasma has a strong cleaning effect (oxidation reaction).
(2) Surface activation: Plasma decomposition of molecular bond materials forms OH groups = active effect.
(3) Surface roughening: Plasma particles destroy the surface, unit: nanometer = rough surface effect.
7. If the electron beam heating method in the coating machine is compared with the traditional resistance heating method, electron beam heating will produce a higher flux density, which is beneficial to the evaporation of high melting point materials and can also improve the evaporation rate to a certain extent.
8. When the PVD coating equipment is working, the material to be evaporated is placed in a water-cooled copper crucible to prevent the material from being contaminated and to produce a high-purity film.
9. The kinetic energy of particles evaporated by electron beam is relatively large, which is beneficial to the precision and bonding force of the film.
What are the disadvantages of PVD coating equipment?
(1) The overall structure of PVD coating equipment is complex, and the Price is relatively high compared with other coating equipment.
(2) PVD Coating Equipment During operation, if the vapor density near the evaporation source is relatively high, there will be some interaction between the electron beam and the vapor particles, affecting the electron flux, and the electron flux will be lost or offset. At the same time, you may trigger the excitation and ionization of steam and residual gas, affecting the quality of the entire piece.
