The float glass has the functions of bacteria repellency and air purification.

Description

technical field [0001] The invention belongs to the technical field of glass production, and mainly relates to antibacterial float glass suitable for making, especially for antibacterial aspects. technical background: [0002] Float glass is widely used in people's daily life as decoration, mirror making, lighting and other building materials. Up to now, there has been no report about antibacterial float glass, and no mass production has been reported so far. At present, the most reported are photocatalytic and slow-release antibacterial glass materials. The photocatalytic type uses the sol-gel method to coat TiO on the glass surface. 2 Photocatalytic thin film, but because it must have ultraviolet light to play a role, the production process of coating on the glass surface is complicated, the lighting performance of the glass is affected, and the application of float glass is limited, so its large-scale industrial application is greatly restricted. On the scope of the Fre...
