Embodiment 1

[0010] CaSiO with a mass ratio of 1:1 3 and TiO 2 At the same time, it is passed into the airflow mill, and after being ground by the airflow mill, it is mixed and processed into a mixture powder with a particle size between 10 and 50 nanometers. The above mixture powder is an ecological bactericide, and the antibacterial rate on the surface of the antibacterial purifier can reach 97.9%, and the harmful gas decomposition rate can reach 99.1%.

Embodiment 2

[0012] CaSiO with a mass ratio of 1:3 3 and TiO 2 At the same time, it is passed into the airflow mill, and after being ground by the airflow mill, it is mixed and processed into a mixture powder with a particle size between 10 and 50 nanometers. The above mixture powder is an ecological bactericide, and the antibacterial rate on the surface of the antibacterial purifier can reach 95.6%, and the harmful gas decomposition rate can reach 97.5%.

Embodiment 3

[0014] CaSiO with a mass ratio of 1:5 3 and TiO 2 At the same time, it is passed into the airflow mill, and after being ground by the airflow mill, it is mixed and processed into a mixture powder with a particle size between 10 and 50 nanometers. The above mixture powder is an ecological bactericide, the antibacterial rate on the surface of the antibacterial purifier can reach 92.7%, and the harmful gas decomposition rate can reach 95.5%.

Abstract

The present invention relates to germicide, and especially preparation process of ecological germicide. The preparation process includes introducing industrial grade CaSiO3 and SiO2 in the weight ratio of 1 to 1-5 into airflow mill, and grinding to granularity of 10-50 nm and mixing inside the airflow mill to form the germicide product. The germicide product may be used in building material, for industrial waste water treatment and automobile tail gas purification, etc. and can kill bacteria and fungi and convert organic nitride, organophosphorus pesticide and other harmful gas into harmless small molecular matter under the action of light.

Description

technical field [0001] The invention relates to a preparation method of a degerming and purifying agent, in particular to a method containing CaSiO 3 and TiO 2 The preparation method of ecological fungicide. Background technique [0002] With the growth of population and the development of industry, energy and environmental issues have attracted much attention. Acid rain, ozone layer destruction and global warming have caused global environmental crises. Application of TiO at home and abroad 2 Such pure raw materials are loaded on the metal surface, and the photocatalytic performance of the material is improved through ion doping, semiconductor compounding, photosensitization, strong acid modification and other technologies, and a series of sterilizing and purifying agents are manufactured. However, there are common problems such as low photoelectric conversion efficiency, less sunlight utilization, complicated manufacturing process and high industrialization cost. The c...
