Coatings industry consumes most qty of titanium dioxide, 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!

Item | ?Performance |
Hiding power | Lighter and thinner plastic products can be produced using tio2 of good hidinding power |
Whiteness | Decide the appearance of the white or light color palstic products light color or white color |
Dispersibility | Affect the production cost of plastic products as bad dispersibility affects the? smoothness and brightness |
Weather resistance | The outdoors plastic products and plastic doors and windows require the weather resistance of tio2 |
Machinability | Titanium dioxide machinability is the vital key to the production efficiency and cost in the production of white masterbatch (especially the concentration variety) |
Performace impact | Titanium dioxide volume of addition can affects the quality of the plastic products, especially in the condition of larger addition |

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.

1,?Liangjiang Brand?rutile titanium dioxide?R994?is manufactured through sulfuric acid process,?using?high-quality titanium ore?as the main raw material,?get finished products after acidolysis,?hydrolysis, calcine,? and?surface treatment.
?
2,?Liangjiang brand rutile titanium dioxide R944, has compact crystal structure, and it is stable in light, so it has better weather fastness, water resistence, and not easily to become yellow. It also has better hiding power, reducing power.
?
3,?Comparation of chlorination process VS. Sulfuric acid process rutile titanium dioxide produced by Liangjiang:
?
?
Sulfuric acid process rutile titanium dioxide
Advantage: take low-cost titanium ore ( or titanium slag ) and sulfuric acid as materials, long-standing technology, ripe technique, lower producing cost.
Disadvantage:? more process, longer technological process, seriously environmental pollution, normal quality stability, lower quality.
Chlorination process rutile titanium dioxide
Advantage: take high-purity artificial rutile (TiO2≥90%) as material, shorter technological process, easily to expand producing capacity, higher quality, can be used as substitute of imported chlorination titanium dioxide.
Disadvantage: Currently, chlorination process titanium dioxide is monaplized by oversea companies, difficulty to import oversea equipments and technology. Higher cost caused by taking high-purity titanium ore as material. More difficulty technology.
Titanium dioxide, TiO2, CAS number: 13463-67-7, EINECS number: 236-675-5, English name is titanium dioxide, formula is TiO2, MW 79.90. Also called titanium white. Titanium dioxide exist in titanium ore and rutile ore. Its high lightness and hiding power resulted from its structure.
Due to the different raw materials and production process, the product performance is different and has different requirements to the weather resistance, hiding power, aesthetics and dispersion titanium dioxide. So the clients should choose titanium dioxide of different quality based on their needs.
