Glass Coating

Glass coating is the process of depositing one or more thin films on the surface of glass to change its optical properties, thermal insulation or other functions. Here are some essential knowledge about glass coating and LOW-E glass:

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.
