A method of nano self-cleaning glass production in the float glass production line

Abstract

The invention relates to a method of nano self-cleaning glass production in the float glass production line. At the end of annealing kiln and above the area between the emergency transverse cutting machines in the float glass production line, the method need add the on-line spray equipment for spraying the nano self-cleaning paint across the float glass production line; evenly and directly spray the nano self-cleaning paint in fine mist on the non-tin surface of the glass at temperature 60-120 DEG C obtained at the end of the annealing kiln to form the nano self-cleaning coating; and then continue to follow the cold end manufacturing process of the float glass line to perform the on-line production to eventually obtain the nano self-cleaning glass. The method of invention saves the glass cleaning process before painting the nano self-cleaning paint during the traditional self-cleaning glass manufacturing. It uses the on-line clean glass obtained at end of the annealing kiln, directly sprays the nano self-cleaning paint on the non-tin glass surface to form the film; and saves the glass cleaning process as well as the resources.

Description

technical field [0001] The invention belongs to the field of functional material technology and glass processing, in particular to a method for producing nanometer self-cleaning glass on a float glass production line. Background technique [0002] Nano self-cleaning glass is a new type of functional glass material developed in recent years. Its appearance has brought people a new way of cleaning and maintaining glass. Studies have shown that TiO 2 The film has the function of self-cleaning. Under the condition of light, TiO on the surface of various substrates (including glass, ceramics, plastics, etc.) 2 It can decompose and adsorb organic matter and avoid the attachment of organic pollutants, so as to achieve the effect of self-cleaning. Therefore, using TiO 2 The prepared self-cleaning glass has attracted the most attention. If the building and venues are equipped with TiO 2 With coated glass, pollutants will not adhere to the surface, and at the same time, it can pu...

Offline production requires a series of complex and tedious procedures such as cleaning and drying

[0006] (2) The heat treatment temperature to the superhydrophilic film is too high, and the production is limited. Therefore, the preparation process of the superhydrophilic film on the self-cleaning glass mentioned in the invention is not suitable for the existing float glass production line, and the obtained The strength of the super-hydrophilic film is low and the production cost is high, which restricts the industrial application of self-cleaning glass
