Problems solved by technology

[0004] At present, there are mainly three kinds of traditional flat glass coating methods, the first is the online chemical vapor deposition (CVD) method, and the second is the online spraying method. The production of antibacterial glass by these two methods mainly has the following problems: one is that the glass is in the During the coating process, the space temperature is too high, which is easy to oxidize the antibacterial agent. Second, the above method can only be coated on one side of the glass, which limits the use effect and scope of the antibacterial glass. The production method is not flexible. The third is vacuum splashing. Spray coating method, using this method to make antibacterial glass, has the following problems: the antibacterial agent finally exists in an atomic state on the surface of the glass, and the antibacterial function is difficult to reach the national standard under normal conditions; and the antibacterial function film belongs to "soft film", not Suitable for long-term exposure and contact use

Description

technical field [0001] The invention relates to a technology for producing antibacterial glass by using a sol-gel coating method, and belongs to the field of deep processing of flat glass. technical background [0002] With the continuous development of social economy and the improvement of human living standards, glass has developed from a single function of lighting, perspective and shelter from wind and rain to multifunctional glass products with various special purposes. In recent years, due to the invasion of humans by SARS virus and bird flu virus, the demand for antibacterial glass and antibacterial glass products in various industries is particularly prominent. Therefore, in recent years, the research on antibacterial glass has developed rapidly, and it has been applied in different industries, and antibacterial glass in different fields has gradually come out. [0003] The processing and manufacture of antibacterial glass is to add antibacterial agents to the glass...
