The English version
Titanium pigment is considered to be the world best performance of a white paint, widely used in coatings, plastic, papermaking, printing ink, chemical fiber, rubber, cosmetics and other industrial. Titanium dioxide (tio2) chemical properties is stable, in the general case does not react with most of the material. In nature there are three kinds of titanium dioxide crystals: titanium plate type, sharp titanium and rutile type. Titanium plate type is the instability of the crystal type, no industrial utilization value, sharp titanium type (Anatase) hereinafter referred to as A model, and Rutile type (Rutile) R type, have the stability of the lattice, are important white pigment and glaze porcelain, and compared with other white paint has excellent whiteness, tinting strength, hiding power, weatherability, heat resistance, and chemical stability, in particular, no toxicity. Titanium dioxide is widely used in coatings, plastics, rubber, printing ink, paper, chemical, ceramics, cosmetic, pharmaceutical and food industries. Coating industry is the biggest user of titanium dioxide, rutile type titanium pigment, in particular, most are consumed in coating industry. Made of white paint, colorful, high covering capacity, tinting strength is strong, consumption province, many varieties, can protect to the stability of the medium, and the paint film mechanical strength and adhesion, to prevent the crack, prevent ultraviolet radiation and water through, extend the life of the paint film. Plastic industry is the second largest user, adding titanium dioxide in the plastic, can improve the heat resistance of plastics products, light fastness, weather resistance, make the plastic products in better physical and chemical properties, enhance the mechanical strength of products, prolong service life. Paper industry is the third big user, titanium dioxide as paper filler, mainly used in advanced paper and thin paper. Join titanium dioxide in the paper, can make the paper with good whiteness, good gloss, high strength, thin and smooth, when printing does not penetrate, light quality. Paper with titanium dioxide generally use without the surface treatment of the sharp titanium type titanium pigment, can have the effect of fluorescent whitening agent, increase the whiteness of paper. But requires the use of laminated paper after surface treatment of rutile type titanium pigment, in order to meet the requirements of light resistance, heat resistance. Titanium dioxide or senior indispensable white pigment in the ink. Containing titanium pigment ink durability, surface wettability is good, easy to disperse. Rutile type titanium pigment, used in the printing ink industry also has a sharp titanium type. Textile and chemical fiber industry is another important application field of titanium dioxide. Chemical fiber use titanium dioxide as main matting agent. Due to the sharp titanium type than the rutile type soft, generally use sharp titanium type. Chemical fiber with titanium dioxide generally does not need surface treatment, but some special species in order to reduce titanium dioxide photochemical effect, avoid fiber in tio2 photocatalytic effect of drop solution, need to surface treatment.
