BACKGROUND
Environmental protection and ecological construction should be one of the major challenges facing humanity in the 21st century all over the world, it is directly related to all over the world human survival and sustainable development of economy and society not only in China. As human awareness of environmental protection and the improvement of global environmental standards, environmental protection industry will become an important emerging industry in the new century.
SUMMARY
The invention relates to a process for producing a nano tio2 titanium dioxide as photocatalytic material. The process comprises the following steps: purifying a diatomite raw material by using grading and acid-washing processes; synthesizing nano titanium dioxide by adopting a hydrolysis-precipitation method through the purified diatomite serving as a carrier, titanium tetrachloride serving as a precursor and hydrochloric acid, ammonium sulfate and ammonium carbonate serving as aids; and filtering, washing, drying and burning the composite particles to form a finished product. The process can thoroughly remove harmful substances, has quite ideal effect on deep treatment of waste gas, lowers the cost and improves the photocatalytic performance.The present invention relates to a photocatalytic material, production process, and more particularly to a process for the production of nano tio2 titanium dioxide as photocatalytic materials.
Brief Description
Jianghu nano tio2 titanium dioxide as a photocatalyst with high photocatalytic activity, chemically stable, safe and non-toxic, etc., in the field of environmental protection has obvious potential advantages. However, the use of chemical test for preparing titanium dioxide photocatalytic materials tend to be highly dispersed fine powder and liquid, there is a direct use of poor dispersion, difficult recovery, poor absorption capacity and other issues, and high cost of production and use in all over the world.
The present invention is made with earth ore as the main raw material, nano tio2 titanium dioxide is catalytically active component, capturing both adsorption and photocatalytic degradation of performance composite materials and efficient photocatalytic pilot production technology, and will for a period of two calcined calcined simplify, streamline the laboratory preparation process; the successful capture of Nano TiO2 such industrial production of new functional materials, multi-segment temperature calcination temperature continuous technology and equipment; solve this composite material used in high-density printed wooden shutters to effective degradation of key technology of indoor formaldehyde gas. Accordingly, the present invention enables the nano TiO2 and new functional materials as an environmentally friendly coating materials application technology to mature. The present invention can completely remove harmful substances, the depth of the exhaust gas treatment effect is very good, but also reduce the cost and improve the photocatalytic properties.
