Embodiment 1

[0037] 1. Titanium dioxide inorganic aqueous solution is made of titanium tetrachloride (16% titanium, 34% chlorine) and 35% ammonia water to generate titanium hydroxide, then add ammonium ions, and then stir the titanium hydroxide three times, precipitate, separate, and wash to improve Purity, then add hydrogen peroxide to generate titanium peroxide, heat the titanium peroxide to dissolve in water, and finally form an amorphous titanium peroxide modified anatase sol

[0038] 2. In the dust-free workshop, first use the existing technology to degrease the glass and perform electrostatic dust removal treatment, and then perform the following operations at a speed of 1m / min: ①under the hot air preheater at a temperature of 50°C to 60°C Carry out preheating; ②Use a reciprocating automatic spray gun to spray nano-silica aqueous solution on the glass surface; ③Use an ultraviolet lamp dryer to dry at a temperature of 50°C to 60°C; ④Use a reciprocating automatic spray gun to dry at a t...

Embodiment 2

[0041] Embodiment 2 is basically the same as Embodiment 1, and can also be applied to fields such as aluminum plates and exterior walls, and can sinter composite titanium dioxide films at room temperature.

Abstract

The invention provides a processing method for sintering and film-formation of self-cleaning glass with photocatalytic performance, which belongs to the technical field of high temperature sintering and film-formation of a titanium dioxide aqueous solution loaded on glass. According to the method, in a dust-free workshop, known technology is employed for degreasing and electrostatic precipitation of glass at first, and then the following operations are carried out at a speed of 1m / min: 1) carrying out preheating with a hot air preheater at a temperature of 50 to 60 DEG C; (2) spraying a silicon dioxide nanometer aqueous solution on the surface of the glass by using a reciprocating automatic spray gun; (3) carrying out drying with an ultraviolet lamp drier at a temperature of 50 to 60 DEG C; (4) spraying a composite titanium dioxide inorganic aqueous solution on the surface of a silicon film by using the reciprocating automatic spray gun; (5) heating to a temperature of 400 to 600 DGE C at a rate of 100 DEG C / min and carrying out high temperature sintering and film-formation for 30 min; and (6) carrying out cooling so as to prepare a composite titanium dioxide nanometer film with a size of 0.2 to 0.3 mu m.

Description

technical field [0001] The invention belongs to the technical field of high-temperature sintering of titanium dioxide aqueous solution supported on glass to form a film. Specifically, it is a kind of film with photocatalytic performance capable of decomposing organic compounds, A processing method for sintering and film-forming self-cleaning glass to prevent static electricity. Background technique [0002] Glass products are widely used as building materials for modern buildings. Today, with the rapid development of China's construction industry, many high-rise buildings have sprung up, and their exterior glass curtain walls are widely used. Glass windows are indispensable, and glass can be seen everywhere as a building decoration material. The glass market is a huge market that will never be saturated in the development of modern economy. The ensuing air pollution has caused these urban landmark buildings to be covered with thick pollutants. The oily components in the a...
