Titanium dioxide Introduction:
Titania, chemical formula: TiO₂, white solid or powdered amphoteric oxide, molecular weight: 79.9, is a white inorganic pigment with non-toxicity, best opacity, best whiteness and brightness, and is considered to be the world today The best white pigment.
China Titania has strong adhesion, is not easy to undergo chemical changes, and will always be white. Widely used in coatings, plastics, papermaking, printing inks, chemical fiber, rubber, cosmetics and other industries.
Titanium White has a high melting point and is also used to make refractory glass, glazes, enamels, clay, high temperature laboratory utensils, etc.
Titanium dioxide is generally divided into anatase (Anatase) and rutile (Rtile).
Titanium dioxide used in Papermaking
The paper industry is the third largest user of Titanium dioxide. Titania manufacturers told us that as paper filler, it is mainly used in high-grade paper and thin paper. Adding titanium dioxide to the paper can make the paper have better whiteness, good gloss, high strength, thin and smooth, non-penetrating during printing, and light weight.
Titanium dioxide for papermaking generally uses anatase-type titanium dioxide without surface treatment, which can act as a fluorescent whitening agent and increase the whiteness of paper. But laminated paper requires the use of surface-treated rutile titanium dioxide to meet the requirements of light resistance and heat resistance.
