Application of nano titanium dioxide jr05 in antibacterial ceramic tile

  The application of nano titanium dioxide jr05 in antibacterial ceramic tiles with the improvement of people's living environment and the enhancement of environmental awareness, there are more and higher requirements for the functions of ceramic materials
Antibacterial ceramic tiles belong to one of antibacterial ceramics

At present, antibacterial ceramic tiles mainly have the following two research directions:
One is to introduce silver inorganic antibacterial agent into glaze to prepare slow-release antibacterial ceramics;
Two, sol gel method is used to coat TiO2 film on the ceramic surface, that is, nano titanium based photocatalytic antibacterial ceramics

Both of them have different degrees of antibacterial effect, but with the extension of time, the release amount of sustained-release ions decreases gradually, and the antibacterial ability also decreases; The photocatalytic antibacterial ceramic is an environment-friendly ceramic with stable sterilization and self-cleaning of ceramic surface

At present, the inorganic salt TiCl4 is used as the raw material to prepare high activity nano titanium dioxide jr05 (5-nanometer super catalytic activity nano titanium dioxide)
The non-interference color photocatalytic antibacterial glazed tile has been prepared, which has been popularized and applied in the market

Preparation method of antibacterial film:
A stable aqueous solution of nano titanium dioxide is prepared by dissolving 5 nano titanium dioxide powder in pure water according to a certain proportion
The film is coated on the clean antibacterial ceramic glazed brick through the film drawing machine
The wet film can be coated repeatedly after drying at 100 ℃ for 10 minutes
Generally, the best effect can be achieved by coating repeatedly for 3 times
Heat preservation in the furnace at 500 ℃ - 600 ℃ for 1H

5 nano high activity titanium dioxide has its unique advantages,
The particle size is very small: the average particle size is 5 nm

Good dispersion performance: 5-nanometer titanium dioxide has good dispersion and can be self dispersed into pure water without stirring
The dispersed liquid can be sprayed on the furniture surface and wall to form a uniform nano coating, which can purify the indoor air

The catalytic activity of titanium dioxide is high, and it can remove harmful gases such as benzene and formaldehyde
5

Good adsorption: nanoparticles are uniform and fine, which can be embedded on the surface of ceramic tiles and play a role for a long time

Market advantages of antibacterial ceramic tiles:
1： High cost performance, with little difference from the price of ordinary ceramic tiles;
2： It has antibacterial and mildew proof effects that ordinary ceramic tiles do not have;
3： Easy to scrub, keep luster for a long time and do not change color
