First, the application of titanium dioxide in enamel and ceramics
The raw materials of porcelain glaze can be divided into 7 types, such as emulsion, refractory, co-solvent, densifier, coloring agent, suspension agent and electrolyte. Enameled whisker
It has milky properties that make the glaze opaque. White glaze in particular must have a stronger opacidity, for which opacidity agent must be added to the glaze.
Titanium dioxide is a strong opacifying agent in enamel. Compared with the glaze of antimony white as opacifying agent, the coating of titanium dioxide enamel is thin and the whiteness is high, while antimony
The white layer must have a thickness of 0.45mm to achieve the covering ability of 0.1-0.15mm thick titanium dioxide.
Therefore, in antimony white enamel need to be coated 2 times, and titanium dioxide only once, you can get full whiteness and opacity. It's also thinner
The enameled layer will greatly improve the mechanical strength of the product such as compression, bending and impact. It is coated with titanium dioxide enamel
The surface of the product is smooth, the acid resistance is strengthened, and the color gloss is better than the antimony white enamel.
Second, the application of titanium dioxide in the ink industry
Titanium dioxide ink manufacturing industry is an indispensable white pigment. Titanium dioxide accounts for the main part of inorganic pigments, and its output accounts for inorganic pigments
More than 70, is a large output, the use of high ink production of inorganic chemical products.
Titanium dioxide is an excellent white pigment in the current ink manufacturing industry. It not only has good physical and chemical stability, but also has good resistance
And has the characteristics of relatively cheap compared with other ink materials. With the development of the world economy and the packaging and publishing printing industry at home and abroad
With the progress of technology, titanium dioxide is increasingly used in a wide range of fields in People's Daily life.
Titanium dioxide is a polycrystalline compound, the molecular formula is Tio2, high whiteness, fine particles, about 0.1-0.7 microns; Refractive index high
2.72; Oil absorption is 45-48, with strong coloring and light dispersion. When the titanium dioxide is dispersed in the medium, the ink can be displayed
High covering power 45-75g/©O. In addition, titanium dioxide also has good light resistance, heat resistance, alkali resistance, weather resistance and hydrophobicity.
Therefore, the application effect of titanium dioxide in high-quality white ink is particularly good, and it is one of the indispensable important raw materials in today's ink industry.
