Anatase Titanium Dioxide Coating Plastic General High Whiteness

Titanium dioxide can be roughly divided into anatase type, rutile type and plate titanium type according to crystal type. The plate titanium type is extremely unstable and the lattice defect can not be used as pigment; Rutile type can disperse visible light better than anatase type, has stronger stability and excellent weather durability; Anatase type uncoated domestic titanium dioxide is the cheapest. Anatase titanium dioxide and rutile titanium dioxide have many different models. 1. R-935 R-935 is the silicon, aluminum inorganic coating and organic treatment agent surface modification, the particle size distribution is uniform and moderate, with excellent whiteness, dispersion, gloss, covering power, weather resistance and other characteristics, suitable for most application fields, is a multi-functional, universal rutile titanium dioxide. It can be widely used in indoor and outdoor coating, powder coating, industrial coating, paint, color paste, ink, rubber paper and other fields. 2. R-936 R-936 is a kind of rutile titanium dioxide modified by aluminum inorganic coating and organic treatment. The particle size distribution is uniform and moderate, and it has the characteristics of high whiteness, easy dispersion, low volatile content, stable performance and good processing rheology. Widely used in master particles, engineering plastics, PVC profiles, pipes, ceramic products, powder coatings and other fields.

3. Type BA01-1

BA01-1 Anatase titanium dioxide is produced by advanced sulfuric acid process, the appearance of white powder, insoluble in water, soluble in hot and concentrated strong acid and alkali, chemical stability, with strong color loss, covering power and other excellent pigment properties. Can be widely used in master particles, paint, ink, rubber, powder coating, plastic, paper, PVC pipe, master particles, ceramics and other fields. 4. BA01-2 BA01-2 Anatase titanium dioxide is produced by advanced sulfuric acid process, the appearance of white powder, insoluble in water, soluble in hot and concentrated strong acid and alkali, chemical stability, with strong color loss, covering power and other excellent pigment properties. Can be widely used in master particles, paint, ink, rubber, glass, leather, cosmetics, soap and other fields. Second, the difference between anatase titanium dioxide and rutile titanium dioxide 1. Different nature Titanium dioxide is a white powder, non-toxic, chemical properties are very inactive, almost no reaction with other elements or compounds at room temperature, O2, H2S, SO2, CO2, NH3 and so on are stable. Insoluble in water, fatty acids, organic acids, weak inorganic acids, slightly soluble in alkali and hot nitric acid, only in concentrated sulfuric acid or hydrofluoric acid for a long time boiling can be completely dissolved. At high temperatures, it can be reduced to low-priced titanium oxide by hydrogen, ammonia, and titanium. Titanium dioxide has high achromatic power, high hiding power, high reflectivity, low specific gravity and other superior pigment properties, is the best one of white pigments. The lattice of rutile titanium dioxide is denser and more stable than that of anatase titanium dioxide, and has good weather resistance, water resistance, and is not easy to yellow and powder, but the whiteness is slightly lower, which is suitable for the manufacture of outdoor pigments. Anatase titanium dioxide lattice space is large, relatively unstable, poor weather resistance, easy to yellow, easy to powder, but high whiteness, suitable for the manufacture of indoor pigments. Anatase titanium dioxide can be converted to rutile titanium dioxide at 915℃. 2. Different uses Titanium dioxide as a white pigment is mainly used in the paint industry, and titanium dioxide used in rutile type pigments is used in the manufacture of automotive paint, ship paint and alkyd enamel and other outdoor paints. Plastic products with external durability also need to use rutile type titanium dioxide to increase the weather resistance. Rutile type titanium dioxide is also used in the ink printing industry, and anatase type titanium dioxide is used in the manufacture of white and light colored indoor paints. Anatase titanium dioxide is also widely used as colorants and fillers for paper, rubber and plastic products. Chemical fiber titanium dioxide is used as a matting agent in synthetic fiber, metallurgical titanium dioxide is used to make titanium-containing high temperature alloy, enamel titanium dioxide is used as an opacifying agent in porcelain glaze, electrode titanium dioxide is used as a slag making agent and a viscose agent in electrode coating, and capacitor titanium dioxide is the main raw material for manufacturing radio ceramic capacitors

Physical characteristics

1. Relative density Among the commonly used white pigments, the relative density of titanium dioxide is the smallest, and among the white pigments of the same quality, titanium dioxide has the largest surface area and the highest pigment volume.

2. Melting point and boiling point Because anatase converts to rutile at high temperatures, the melting and boiling points of anatase titanium dioxide are virtually nonexistent. Only rutile titanium dioxide has a melting point and boiling point, the melting point of rutile titanium dioxide is 1850 ° C, the melting point in the air is (1830±15) ° C, and the melting point in the oxygen rich is 1879 ° C, and the melting point is related to the purity of titanium dioxide. The boiling point of rutile titanium dioxide is (3200±300)℃, and titanium dioxide is slightly volatile at this high temperature.

3. Dielectric constant Titanium dioxide has excellent electrical properties because of its high dielectric constant. In the determination of some physical properties of titanium dioxide, it is necessary to consider the crystallization direction of titanium dioxide crystals. Anatase titanium dioxide has a relatively low dielectric constant of only 48.

4. Electrical conductivity Titanium dioxide has the properties of a semiconductor, its conductivity increases rapidly with the rise of temperature, and it is also very sensitive to hypoxia. The dielectric constant and semiconductor properties of rutile titanium dioxide are very important to the electronics industry, which can be used to produce electronic components such as ceramic capacitors. 5. Hardness According to the Mohs hardness scale of ten points, rutile type titanium dioxide is 6 ~ 6.5, anatase type titanium dioxide is 5.5 ~ 6.0, so in chemical fiber extinction in order to avoid wear of the spinet hole and anatase type.

6. Hygroscopicity Although titanium dioxide is hydrophilic, its hygroscopicity is not too strong, and rutile type is smaller than anatase type. The hygroscopicity of titanium dioxide has a certain relationship with the size of its surface area, which is large in surface area and high in hygroscopicity, and is also related to surface treatment and properties.

7. Thermal stability Titanium dioxide is a substance with good thermal stability. Titanium dioxide (or titanium dioxide) is widely used in a variety of structural surface coatings, paper coatings and fillers, plastics and elastomers, and other uses include ceramics, glass, catalysts, coated fabrics, printing inks, roof paving and flux.
