Abstract

The invention opened a detection method of the antiseptic activity which belongs to the TiO2-film of self-cleaning class. To get the sterilization fraction surviving by detecting the microbe density of sample surface after lighting. The process is easy to do and appropriate, convenience. So we can get the result quickly.

Description

technical field [0001] The invention relates to a method for testing the antibacterial activity of glass and its products. Background technique [0002] Titanium dioxide film self-cleaning glass has a good bactericidal effect under ultraviolet light, which can effectively reduce the concentration of bacteria on the glass surface and improve its sterilization efficiency.
