1. Glass Coating Equipment:
- Magnetron Sputtering Equipment: Magnetron sputtering is a commonly used glass coating technology. It utilizes high-energy ions to bombard the target, causing the surface atoms or molecules to be released and deposited onto the glass surface.
- Evaporation Equipment: Evaporation is another common glass coating method. It sublimates the target by heating it and deposits it on the glass surface.
- Ion Beam Equipment: Ion beam coating uses an ion beam to bombard the target and control the deposition of the film. It provides higher deposition rates and better control.
2. LOW-E Glass:
- LOW-E (Low Emissivity) glass is a type of glass with low heat radiation properties. It reduces the transmission and dissipation of heat and improves thermal insulation.
- LOW-E glass usually has one or more metal oxide films. These films reflect infrared radiation and reduce heat transfer.
- Typical LOW-E glass construction involves depositing a thin film of metal oxide (such as tin dioxide or silica) on the glass, which is then covered with a protective layer.
3. Other glass coating applications:
- Anti-reflective coating: one or more layers of anti-reflective film are deposited on the glass surface to reduce light reflection and improve transmittance and visual clarity.
- Coated glass devices: such as solar cells, liquid crystal displays, etc., need to deposit a specific functional film layer on the glass to realize its working principle.
