Embodiment Construction

[0023] Sample source: On-site sampling of the self-cleaning glass production line with an annual output of 100,000 square meters of Hubei Three Gorges New Building Materials Co., Ltd.

[0024] Acetone is a common solvent widely used in various industrial and domestic products. For example, acetone is frequently used as a solvent in the printing industry and in analytical laboratories; it is also a major component of many common household chemicals. Therefore, we choose it as a simulated pollution compound. The photocatalytic oxidation of acetone is based on the following chemical reactions:

[0025]

[0026] The photocatalytic activity experiment of titanium dioxide thin film self-cleaning glass for the degradation of acetone in air was carried out at normal temperature and pressure using a 7000 ml photocatalytic reactor. The area of ​​the titanium dioxide thin film photocatalyst was kept at about 140 cm in each experiment 2 . After the thin film photocatalyst is pl...

Abstract

The process of testing the photocatalytic activity of self-cleaning glass with titania film includes the following steps: preparing glass sample; connecting photocatalytic reactor with opto-acoustic-infrared gas monitoring instrument, setting near ultraviolet lamp and mini fan inside the photocatalytic reactor, and connecting drier with the photocatalytic reactor and mini vacuum pump; setting the sample inside the photocatalytic reactor and injecting the simulating pollutant into the photocatalytic reactor; homogenizing the components inside the photocatalytic reactor, controlling the initial concentration of pollutant and vapor and test temperature; regulating light strength and the concentration of the degraded medium and degraded product; continuous on-line monitoring with the opto-acoustic-infrared gas monitoring instrument and outputting test result; and calculating degradation rate. The present invention has easy operation and convenient detection.

Description

technical field [0001] The invention relates to a test method for degrading simulated pollution compounds of glass and its products. Background technique [0002] The sol-gel method is an effective way to prepare highly active titanium dioxide thin film self-cleaning glass. Under the irradiation of ultraviolet light, the light filtering activity of titanium dioxide thin film self-cleaning glass can degrade many kinds of pollutants, but there is no national standard yet. Test method for photocatalytic activity of self-cleaning glass with titanium dioxide film. Contents of the invention [0003] The purpose of the present invention is to provide a method for testing the photocatalytic activity of titanium dioxide thin film self-cleaning glass with strong operability, practicality and convenience. [0004] The object of the present invention is achieved like this: a kind of titanium dioxide thin film self-cleaning...
