Product details

titanium  oxide  scientific name of titanium dioxide (titanimum  oxide ). It has rutile (Rutile R-type) and anatase (Auatase A-type) Two kinds of structures, rutile crystal structure of dense, relatively stable, and optical activity is small, so weather is good, while there is a high hiding power, color power consumption

And thus have a better application performance, access to a wider range of applications.
 Titanium dioxide in the rubber industry, both as a coloring agent, but also has been strengthened, anti-aging, filling the role. In the white and colored rubber products by adding titaniumWhite powder, in the bright sunlight, sunlight-resistant, non-cracking, do not change color, stretch rate is high and the acid and alkali. Rubber with titanium dioxide is mainly used in automobile tires toAnd rubber shoes, rubber flooring, gloves, sports equipment and so on, generally the main anatase. However, for the production of automobile tires, often adding a certain amount of gold redStone products, to enhance the ability of anti-ozone and ultraviolet resistance.

The application of titanium dioxide in cosmetics are becoming increasingly widespread. Because titanium dioxide non-toxic, superior than the white lead, all kinds of titanium dioxide powder used to replace almost all ofLead white and zinc white. Powder in only 5% -8% by adding titanium dioxide can be permanently white, so that a more creamy flavor, with adhesion, absorption, andHiding. In the gouache and cream in the titanium dioxide can be reduced and transparent oily feeling. A variety of other spices, sunscreen, soap flakes, white soap and toothpasteTitanium dioxide is also available.

 1, physical properties
 1) Relative density of
 In the commonly used white pigment, titanium dioxide, the relative density of the smallest, of equal quality white pigment, titanium dioxide surface area of the largest YenThe maximum volume of material.
 2) The melting and boiling points
 Since anatase at high temperatures will be transformed into rutile, the anatase titanium dioxide, the melting point and boiling points are actually non-existent. Only GoldRedstone-type titanium dioxide are melting and boiling points, rutile titanium dioxide, the melting point of 1850 ℃, the melting point of the air (1830 ± 15) ℃, oxygen-richThe melting point of 1879 ℃, melting point and purity of the titanium dioxide. Rutile Titanium Dioxide boiling point of (3200 ± 300) ℃, in this high-temperatureTitanium dioxide under a little volatile.
 3) The dielectric constant
 Due to the higher dielectric constant of titanium dioxide and therefore have excellent electrical properties. In the determination of certain physical properties of titanium dioxide must be considered whenThe crystallization of titanium dioxide crystal orientation. Anatase titanium dioxide is relatively low dielectric constant, only 48.
 4) conductivity With the performance of the semiconductor titanium dioxide, and its conductivity increases with temperature increased rapidly, but also very sensitive to hypoxia. Rutile The dielectric constant of titanium dioxide and semiconductor nature of the electronics industry is very important, can make use of the nature of the production of ceramic capacitors and other electronic components.
 5) Hardness
 Mohs hardness is according to the system scale, rutile titanium dioxide 6 to 6.5, anatase titanium dioxide is 5.5 ~ 6.0, and therefore fiber mattingSpinneret holes in order to avoid wear and tear and the use of anatase.
 6) hygroscopic
 Although the hydrophilicity of titanium dioxide, but the moisture is not too strong, rutile than anatase small. The moisture absorption of titanium dioxide with a large surface areaHave a certain relationship between a small surface area large, high moisture absorption, but also to deal with the nature of the surface.
 7) Thermal stability
 Thermal stability of titanium dioxide are good material.
 8) size
 Titanium dioxide particle size distribution is a comprehensive index, which seriously affected the performance of titanium dioxide pigment and product application performance, therefore, for hiding powerAnd decentralized nature of the discussion could be directly from the particle size distribution analysis.
 The factors that affect the particle size distribution of titanium dioxide is more complicated, first hydrolysis of the original particle size, by controlling and regulating the hydrolysis process conditions, so thatThe original size within a certain range. Followed by the calcination temperature, partial titanate in the calcination process, the particles undergo a transformation of crystalline phase and growth, controlSystem suitable for the temperature, so that growth of particles within a certain range. The last is the product of crushing, usually Raymond transformation and analyzer speed regulationTo control the crushing quality, while other grinding equipment can be used, such as: universal mill, jet mill and hammer mill equipment. 2, the chemical nature of the
 The chemical properties of titanium dioxide is extremely stable, is a kind of acidic oxides of the sexes. At room temperature almost no reaction with other elements and compounds,Pairs of oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, sulfur dioxide does not work, do not dissolve in water, fat, not soluble in diluted acid and inorganic acids, alkalis,Is only soluble in hydrofluoric acid. However, in light under the action of titanium dioxide can occur consecutive redox reactions, with photochemical activity. This kind of photochemical activity, In the ultraviolet irradiation anatase titanium dioxide is particularly clear that the nature of titanium dioxide inorganic compounds even if some of the photosensitive oxidation catalyst, but alsoTo restore the catalyst in certain organic photosensitive.
 Emergency treatment: isolation leakage polluted area, restricting access. Recommended emergency personnel wearing a dust mask (full cover), wearing overalls in general operations. Avoid dust, carefully scan, bag placed transfer to a safe place. If a large number of leaks, with plastic sheeting, canvas cover. Shipped to recycling or waste collectionMaterial disposal sites.
 Titanium dioxide (or titanium dioxide) is widely used in various types of structure, surface coating, paper coating and filler, plastics and elastomers, and other uses includingCeramics, glass, catalysts, coating fabrics, printing inks, roofing granules and flux. According to statistics, in 2006 the global demand for titanium dioxide, up to 460Million tons, which accounted for 58% of the paint industry, plastics industry accounted for 23%, paper 10%, other 9%. Titanium dioxide can with ilmenite, rutile PreparationCan also be used titanium slag Preparation. Titanium dioxide production process, there are two: namely, sulfate and chloride process technology, Kraft technology than the chloride method is simple and, You can place low and cheaper supplies of minerals. About 47% of the world's production capacity with sulfate process, 53% of capacity chloride process.
 The world's second-largest titanium dioxide producer - the United States Millennium Chemical Company recently said that the next few years the global titanium dioxide demand growth will exceed capacityGrowth rate, thus contributing to higher rates of titanium dioxide unit starts is expected to start the 2010-2011 rate of the world's titanium dioxide 90%. LeamdreSeoul Chemical Company inorganic chemicals, vice president Gary Cianfichi recently held in Barcelona, said the annual meeting of the European titanium dioxide, the global operating rate of titanium dioxideBy 2004, more than 90% reduction to the current 87% -88% level, expected future market will be further improved, the demand for the next five years, the average growth rate of2.8% / year, while supply growth is only 1.9% / year. Titanium dioxide production from the world in 2005, 4 million tons / year increase to 5.3 million tons / year, And is mainly concentrated in China, it is estimated that China titanium dioxide production capacity has reached 750 thousand tons / year.
 Very little new capacity, mainly Lyondell's investment 20 million U.S. dollars in France Thann ultrafine titanium dioxide project, Tronox, andKumba Resources's 50/50 joint venture company plans to invest Tiwest million pairs 3500-4500 in Australia Kwinana HealthProduction plant expansion 4-5 million tons / year is planned for completion by 2009. Huntsman Chemical Company is currently investing 80 million U.S. dollars British Greatham NewTo build a 5 million ton / year titanium dioxide plant, will use the Icon technology. DuPont has signed an agreement with China, in 2010 inChina, the EastCamp construction of a 20-million ton / year plant.
 Titanium dioxide in Asia and Europe last year, prices were relatively stable last year, the U.S. titanium dioxide prices rose by 10% -16% this year, a quarter of the U.S. market to payFor the price of 2300-2400 U.S. dollars / ton, the European price for 1900-2000 euros / ton, the Asia-Pacific region spot price 2200-2300 U.S. dollars / ton
