This method is a high-tech application method to realize glass variety innovation online.
Production process of surface microphase treatment method
Weigh the special raw material (main powder) and add it into the raw material processor. After adding water and specific additives into the raw material processor, the liquid-phase pretreatment raw material is made. The liquid phase pretreatment raw materials are transported to the liquid storage tank and then to the liquid storage tank, and the liquid phase is transported to the microprocessor under automatic control. The microprocessor changes the liquid phase into micro-phase and then delivers it to the micro-phase distributor. The distributor distributes the microphase on the surface of the glass ribbon. Under certain conditions, the microphase is "nano-phase", which makes the single particle of nano-phase combine with silicon ions in the glass body. A coating with self-cleaning and sterilization function under photocatalyst is formed on the glass ribbon, that is, solid-phase bonding. The self-cleaning sterilized glass solid with functional layer is treated (i.e. annealed, cut, tested, packaged, etc.). ) becomes self-cleaning sterilization glass through the cold end of the glass production process.

Main characteristics of surface microphase treatment
Anatase titanium dioxide crystals were successfully formed by surface microphase treatment, and the content was high. Under normal conditions, it has strong superhydrophilicity and photocatalytic activity, and glass has strong self-cleaning and sterilization functions. At the same time, organic pollutants are not used in production, there is no explosion limit of substances, and gas protection is not needed. The surface microphase treatment method is used in the cold end online production of glass production line, which is convenient to operate and can automatically control the production operation. The generated titanium dioxide film is hard and the visible light transmittance of the product is high.
The surface microphase treatment method can be used for on-line grafting of flat glass production line without affecting the normal production of glass factory, and the production cost is low. Titanium dioxide exists in nano-anatase crystal form, which has high self-cleaning and sterilization efficiency. This method can be used for online technical grafting or offline grafting, which is very convenient. And can produce a variety of functional glass, can realize the production of composite functional glass, and can also be compounded by other methods. Grafting technology does not affect the production process conditions, equipment and facilities of the original glass factory, and does not affect the production of the original glass varieties. It can be directly grafted in production, with wide application temperature range, good production safety and wide application range. It can be grafted not only directly on the float glass production line, but also on the horizontal drawing, calendering and vertical drawing glass production lines. This technology can also be used for off-line grafting in glass deep processing plants.
The technology of producing self-cleaning aseptic glass by microphase treatment is different from sol-gel method and vapor deposition method. Comparatively speaking, the process has strong adaptability, the production environment is closer to human nature (normal pressure, moderate temperature), the production control is convenient, the environmental pollution in glass production is not increased, the investment is low, the cost is low, and it can be directly grafted on the glass line (without stopping production). The self-cleaning sterilization glass produced by surface microphase treatment has the characteristics of hard film (together with the glass body), good superhydrophilicity under normal conditions, strong photocatalytic activity, strong sterilization function and uniform film.
