Abstract
Description
Technical Field
[0001] This utility model relates to the field of float glass processing technology, and in particular to an adsorption device for reducing tin defects on the surface of float glass sheets. Background Technology
[0002] The surface of float glass is formed by float polishing with molten tin, resulting in a smooth, ripple-free surface with a surface ripple density typically less than 50nm. This results in minimal optical distortion and a light transmittance of 89%-91.5%. The flame polishing process makes the air surface (upper surface) as smooth as a mirror, while the tin surface (lower surface) is protected from oxidation by a protective gas environment.
[0003] The existing float glass production process involves flowing molten glass through a tin bath containing molten tin to form the glass and then annealing it. The tin bath is a thermal device used in glass forming; it contains molten tin and is filled with reducing gases to protect the tin from oxidation. However, the tin bath is a semi-open thermal device, and the molten tin is inevitably oxidized by the infiltrated air. Therefore, the space inside the tin bath contains not only reducing gases but also small amounts of tin ash and metallic tin vapor.
[0004] However, since the molten tin is inevitably oxidized by the infiltrated air, tin ash and metallic tin vapor are generated inside the tin bath. After the tin bath has been running for a period of time, the tin ash and tin vapor will adhere to the top of the tin bath and cannot be cleaned. If this continues for too long, the deposits on the top of the tin bath will fall off and drip onto the liquid glass plate, causing quality defects such as optical distortion points and metallic tin inclusions on the glass plate, making it inconvenient to use.
