3. Liangjiang- brandtiatnium dioxide anatase production process:
?
?
Titanium dioxide, stable chemical properties. It is a kind of partial acid amphoteric oxide,does not react with other elements and compounds at normaltemperature, doesn& acute;t work for oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, sulphur dioxide, insoluble in water, fat, also in dilute acid and inorganic acid, alkali, only soluble in hydrofluoric acid.But under the effect of light, titanium pigment, can occur continuous REDOX reaction and has the photochemical activity.This kind of photochemical activity, particularly under ultraviolet light sharp, this nature make titanium dioxide even some inorganic compounds photosensitized oxidation catalysts, and some organic compounds photosensitive reduction catalyst.

From this table, titanium dioxide rutile compared with titanium dioxide anatase,
relatively lack of surface treatment technology. To the high weatherability products,
can only use the rutile type; To the lower weatherablility, higher whiteness,
titanium dioxide anatase is the best choice.

According to the requirements of the coating properties, to choice the satisfied for the coatings and coating?
properties is very important. From the table, with the chlorination process rutile type titanium pigment?
production product is the best, currently we could see rutile chlorination is the best white pigement on?
the market . The comprehensive performance is excellent, the first choice in the white pigments, also the?
necessary pigment in light color.Because of the different surface treatment technology, titanium dioxide?
has different models. According to the characteristics of the mixture of coating, such as the high gloss,
?high covering power, or high pulverization, to choice the relevant type.Rutile sulfuric acid process,?
due to the conversion rate of anatase to rutile is lower than chlorination process, so the whiteness of the?
product and the stability of the light from chlorination process is a bit difference, but the price is lower.

Titanium dioxide , coatings as he biggest parts, especially the rutile type.The global coating industries occupy 58% - 60%, mainly because the aspects of the performance is much better than the other white pigments. So the coating using by titanium dioxide is much higher than ordinary filler, because titanium dioxide is an integral part of in the coating, covering and adornment, its role is not only more important is to improve the physical and chemical properties of paint, bust also to improve the mechanical strength of the coating, adhesion, anticorrosive, light and weather resistance.So during of the production of coatings, It’s reasonable for us to choose the suitable type and specs!

Plastic is the second largest parts for titanium dioxide, occupying about 20% of the total world titanium dioxide demands, There are more than 50 brands belongs to plastic specials in the world 500 barands. Requirements for plastic, fine particle, good dispersion performance;Good heat resistance and light resistance,During the heat and the plastic forming process , the finished product does not change color in sunlight exposure and use process. Most of the particle size in plastic is fine. In the plastics, to join titanium dioxide
can improve the heat resistance of plastic products, light fastness, weather resistance, make the plastic products to improve the physical and chemical performance.The strong mechanical strength can extend their life!
The effect of titanium pigment in the plastics industry mainly has two aspects, one is used as the basic white pigment, provide cover (white color); the second is to block uv light, used as uv screen disadvantages agent, used for outdoor plastic products to provide a good weatherability. For the Common plastic,it does not require the weatherability, focuses More on the paint performance requirements.
Due to the characteristics of palstic products, When choosing different, should be taken into account in accordance with the technical requirements of plastic products, mainly to choose anatase or rutile, not same as the coatings, inks, paints.

Paper is the third largest parts for titanium dioxide, As the paper filter, mainly use in high grade paper and thin paper. To join titanium dioxide in the paper can make the paper good whiteness, good gloss, high strength, thin and smooth, not penetrate when printing, light quality.Titanium dioxide for Paper generally use the titanium dioxide without the surface treatment, can have the effect of fluorescent whitening agent, increase the whiteness of paper, but laminated paper use requires the surface treatment of rutile titanium, to meet the requirements of light resistance and heat resistance.
Different paper use, different type titanium dioxide, titanium dioxide rutile, good oxidation resistance good weather resistance, mainly used for decorative paper and high ash paper of weather resistance; While titanium dioxide anatase used for the low transparency and low ash paper,not high rquirement for? weather resistance.Although chlorination process and sulfuric acid process can produce rutile type, but the chlorination process titanium pigment , whiteness, the red crystal type of content, especially the stability of the finished product is better than that of the sulfuric acid method, suitable for use in the decorative paper and high ash;And coinage in the paper and the low ash must be used titanium dioxide by sulfuric acid, in order to meet the requirements of opacity for two kinds of paper.
