The use of rutile and anatase titanium dioxide powders is definitely different, depending on their differences to determine their range of use. The rutile type is better than the anatase type in powdering resistance and gloss retention. The surface of pure anatase titanium dioxide particles is photochemically active in the presence of water vapor and oxygen, and is not photochemically stable. It can even promote the degradation of the binder around its particles, so it is necessary to first stabilize itself. Chemical. The size of its stability can be obtained by controlling the type and amount of different inorganic oxides.
Both the rutile type and the anatase titanium dioxide have a high whiteness in the visible wavelength range, and their reflectance to light is high. However, in the wavelength range of ultraviolet light smaller than the visible light range, the performance exhibited by the two different crystal forms is quite different. For rutile (red line) in the UV-A band with strong lethality, its reflectivity to ultraviolet light is much lower than that of blue anatase. In other words, its absorption rate of ultraviolet light is much higher than Blue anatase type. In this case, the film-forming organic resin around it has much less UV light to share.
The application range of rutile titanium dioxide in the application process of rutile titanium dioxide, one should be considered, when manufacturers use titanium dioxide, there is also an idea on the cost issue. Most of rutile titanium dioxide is produced in high-end products. For the production of titanium dioxide powder for coatings, titanium white plastic lacquer wood lacquer and high-grade printing paste will use gold feldspar type titanium dioxide, only rutile titanium dioxide can give high-end products beautiful opacity, high gloss, dispersion In the process, it will also save time and effort.
The application range of anatase titanium dioxide in the production of plastics, ink, popular printing paste, new year painting, coating and other industries, anatase titanium dioxide is still very popular. The price of anatase titanium dioxide is low, and it also has a certain degree of whiteness. It is only in the production, it needs to be ground, or it can be produced by high-temperature technology to make the anatase titanium dioxide powder strong enough to reach the ideal state.
