Nano titanium dioxide is a anatase phase white loose powder, which has strong ability to shieding UV, has good dispersion and weather resistance. It is with properties of anti-line, anti-bacterial, self-cleaning, anti-aging properties that can be used for cosmetics, functional fibers, plastics, inks, coatings, paints, fine ceramics, and other fields.

With the development of society, the progress of science and technology, the raise of culture, the level of awareness of people's health also is increasingly strengthened. Most diseases are caused by bacteria, fungi and other pathogens invade human beings, animals and plants, as occurred in a series of reactions, affecting people's health and even life-threatening, microorganisms can also cause a variety of industrial materials, food, cosmetics, pharmaceuticals and other decomposition, deterioration, degradation, corruption, bring significant economic losses. Therefore, the products of having a bactericidal and antimicrobial effects have draw more and more people's attention. Hongwu International Group LTD Anatase Nano titanium dioxide, with good photocatalytic properties, which has broad applications in wastewater treatment, air purification, anti-bacterial deodorant, etc., so in recent years, it has become a hot spot for research scholars domestic and overseas.

In general, inhibit bacterial development and performance enhancement called antibacterial, kill bacteria or near sterility performance called sterilization, antibacterial or bactericidal function known as antimicrobial materials. Synthetic antimicrobial organic and inorganic materials can be divided into two categories, since the presence of organic antibacterial materials antibacterial weak, heat resistance, poor stability, self-decomposition products and volatiles may be harmful to human beings, it is not suitable for high-temperature processing, which limit their use, and gradually replaced by inorganic antimicrobial material class. Traditional inorganic antimicrobial agent is consisting of silver, copper, zinc and other metal ions supported on zeolite, phosphate wrong, fusible glass, silica gel, activated carbon carrier.

In recent years, anatase titanium dioxide, as the representative of the photocatalytic materials has been extensively studied. Since the effects of Ti02 photocatalytic antibacterial material are lasting and titanium dioxide itself is excellent but inexpensive, non-toxic, chemical stability. By using sunlight, ultraviolet fluorescent lamp contains light as the excitation source can have an antibacterial effect, and air purification, sewage treatment, photocatalytic self-cleaning effect, the antibacterial process is simply described as: nano titanium dioxide, a hole larger than the band gap energy of the excitation light, generated or electronic of oxygen and water in the environment play a role, such as active oxygen free radicals and organic molecules in the cells of a chemical reaction, and then break down the cells and achieve anti-bacterial purposes.

In addition, these reactive oxygen can not only quickly and thoroughly kill bacteria, but also can degrade cell lysate endotoxin, and other organic chemical contaminants, making it completely mineralized material having the advantage of other antibacterial incomparable. In the aspect of antibacterial, it has demonstrated broad application prospects, which has become a new generation of inorganic antibacterial purification materials.
