Titanium dioxide chemical properties are more stable, generally does not react with other substances, mainly divided into plate titanium dioxide, anatase titanium dioxide, rutile titanium dioxide. The market demand of titanium dioxide is very large, and it is used in various fields. Including: paint, paper, plastic, prevention and control, ink, medicine and other industries, the following details to you.

Use of titanium dioxide:

Titanium dioxide is widely used in coating, plastic, rubber, ink, paper, chemical fiber, ceramics, daily chemicals, medicine, food and other industries. Paint industry is the largest user of titanium dioxide, especially rutile titanium dioxide, most of the paint industry consumption. Paint made of titanium dioxide, bright color, high covering power, strong coloring power, dosage, variety, the stability of the medium can play a protective role, and can enhance the mechanical strength and adhesion of the paint film, prevent cracks, prevent ultraviolet and moisture through, prolong the life of the paint film.

The plastic industry is the second largest user, adding titanium dioxide in plastic, can improve the heat resistance, light resistance, weather resistance of plastic products, improve the physical and chemical properties of plastic products, enhance the mechanical strength of products, prolong the service life.

Paper industry is the third largest user of titanium dioxide, as a paper filler, mainly used in high-grade paper and thin paper. Add titanium dioxide in the paper, can make the paper has good whiteness, good gloss, high strength, thin and smooth, printing does not penetrate, light quality. Paper titanium dioxide is generally used without surface treatment of anatase titanium dioxide, can play the role of fluorescent whitening agent, increase the whiteness of paper. However, laminate paper requires the use of rutile titanium dioxide after surface treatment to meet the requirements of light resistance and heat resistance.

Titanium dioxide or advanced ink indispensable white pigment. Containing titanium dioxide ink durability does not change color, good surface wettability, easy to disperse. Ink industry used titanium dioxide rutile, also have anatase type. String 3

Textile and chemical fiber industry is another important application field of titanium dioxide. Chemical fiber titanium dioxide is mainly used as extinction agent. Since the anatase type is softer than the golden red type, the anatase type is generally used. Chemical fiber titanium dioxide generally does not need surface treatment, but some special varieties in order to reduce the photochemical action of titanium dioxide, avoid fiber in the photocatalytic action of titanium dioxide degradation, need surface treatment.

Titanium dioxide in the rubber industry as a colorant, but also has the role of reinforcing, anti aging, filling. Add titanium dioxide in white and color rubber products, under sunlight, sun resistance, no cracking, no discoloration, stretching rate and acid and alkali resistance. Rubber titanium dioxide, mainly used for car tires and rubber shoes, rubber floor, gloves, sports equipment, generally with anatase type. But for car tire production, often add a certain amount of rutile products, to enhance the ability to resist ozone and uv.

Titanium dioxide is widely used in cosmetics. Because titanium dioxide is non-toxic, far superior to lead white, all kinds of fragrance powder almost titanium dioxide to replace lead and zinc white. 5%-8% titanium dioxide powder can be added only in sweet powder permanent white, make spice more slippery, have adhesion, absorption and cover. Titanium dioxide in gouache and cold cream can abate greasy and transparent feeling. Titanium dioxide can also be used in other spices, sunscreen, soap, white soap and toothpaste.

The enamel made of titanium dioxide has strong transparency, small quality, strong impact resistance, good mechanical properties, bright color, not easy to pollution and so on. Titanium dioxide for food and medicine is of high purity, low content of heavy metals and strong covering power.
