Pure Titanium Dioxide Powder for Paints and Plastics Manufacturing¹

Product Description Product DescriptionIntroduction to Titanium DioxideTitanium dioxide (\(TiO_2\)), commonly known as titanium white, is a white inorganic pigment. Due to its excellent properties such as high hiding power, high whiteness, and good chemical stability, it plays a pivotal role in numerous industries.Physical and Chemical PropertiesAppearance and Color: It appears as a white powder, and its whiteness is extremely high, which is one of the important indicators for measuring the quality of titanium dioxide. The whiteness of high - quality titanium dioxide is close to the theoretical whiteness, endowing the applied products with a bright and white appearance.Hiding Power: Hiding power is a key property of titanium dioxide. It can effectively scatter and absorb light, covering the base color of the coated object's surface, thus presenting a uniform color. High hiding power enables a good covering effect to be achieved with a relatively small amount of titanium dioxide, reducing production costs.Chemical Stability: Titanium dioxide has stable chemical properties and does not react easily with most chemical substances. This property allows it to maintain stable performance under different environmental conditions. Whether in acidic, alkaline, or high - temperature environments, it can function normally and is widely used in various industrial and daily - life products.Crystal Forms: There are mainly two crystal forms, namely rutile type and anatase type. Rutile - type titanium dioxide has a higher refractive index and better weather resistance, making it suitable for fields with high requirements for weather resistance, such as automotive coatings and exterior wall coatings. Anatase - type titanium dioxide, on the other hand, has a relatively lower cost and better whiteness, and is commonly used in general coatings, plastics, papers, and other products with low requirements for weather resistance.Preparation MethodsSulfuric Acid Method: It is a relatively traditional preparation method. Using ilmenite as the raw material, through a series of complex technological processes such as sulfuric acid decomposition, impurity removal, hydrolysis, and calcination, the titanium dioxide product is finally obtained. This method has a mature process, but a large amount of waste residue and wastewater are generated during the production process, putting great pressure on the environment. Moreover, the production process is long, and the cost is relatively high.Chlorination Method: It is a preparation technology that has developed rapidly in recent years. Using high - grade titanium concentrate or natural rutile as the raw material, it reacts with chlorine gas at high temperatures to generate titanium tetrachloride, and then the titanium dioxide is obtained through steps such as oxidation and purification. The chlorination method has a short production process and high product quality, especially in the production of rutile - type titanium dioxide. It also has relatively less environmental pollution. However, this method has high requirements for raw materials, large investment in production equipment, and high technical difficulty.Application FieldsCoating Industry: It is the largest application field of titanium dioxide. In various coatings, such as architectural coatings, industrial coatings, and automotive coatings, titanium dioxide, as a white pigment, provides good hiding power and decorative properties. In architectural coatings, it can make the wall present a white and long - lasting appearance; in automotive coatings, it not only endows the vehicle body with a bright color but also improves the weather resistance and durability of the coating.Plastics Industry: Adding titanium dioxide can improve the whiteness, gloss, and light resistance of plastic products. It is widely used in products such as plastic films, plastic pipes, and plastic profiles, improving the appearance quality of plastic products and extending their service life. For example, adding titanium dioxide to agricultural plastic films can enhance the film's shielding effect against ultraviolet rays, prevent the film from aging, and extend its service life.Paper Industry: It is used for paper filling and surface coating. As a filler, it can improve the opacity and whiteness of paper and enhance the printing adaptability of paper. When used for surface coating, it can make the paper surface smoother, improve the printing quality, and at the same time enhance the water resistance and strength of paper.Ink Industry: Titanium dioxide plays a role in color adjustment and increasing hiding power in inks. It gives inks good color saturation and printing adaptability and is widely used in various ink products such as offset inks, gravure inks, and flexographic inks, ensuring that printed products have bright and clear colors.Cosmetics Industry: Due to its non - toxicity, odorlessness, white color, and good hiding power, it is widely used in cosmetics such as foundation, eyeshadow, and lipstick. It can endow cosmetics with good texture and concealing effect, while ensuring the safety of the products.Other Fields: It is also applied in industries such as rubber, ceramics, electronics, and food. Adding titanium dioxide to rubber can improve the anti - aging performance and strength of rubber products; in ceramics, it can improve the color and quality of ceramics; in the electronics industry, it can be used to manufacture electronic components such as capacitors; in the food industry, specially treated food - grade titanium dioxide can be used as a food additive in products such as candies and beverages, playing a role in color adjustment.Detailed PhotosProduct ParametersProduct name:Titanium dioxideAppearance:White powderCAS No.: 13463-67-7EINECS No.:257-372-4Molecular formula:TiO2Molecular weight:79.8658Melting point:1830 oCBoilting point:2900 oCwater-solublility0.5%Storage Conditions:room tempretureactive TiO2 content93%Average particle size0.3um Packaging & Shipping
