1.?Comparation of chlorination process VS. Sulfuric acid process rutile titanium dioxide produced by Liangjiang:

?

?



?

?

Chlorination process

Advantages:?using the less impurities artificial rutile of 90% tio2 purity as the raw material, short process flow, production capacity easy to expand and continue, high quality.

Disadvantages: because of the monopoly of the foreign companies, it’s hard to bring in the foreign technology and equipment in China. Besides, due to the raw material of high content titanium dioxide ore, the production cost is relatively high and the process is hard.

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.

1.?Titanium dioxide quality requirements for plastic, PVC and masterbatch

?

- - - -
Items | 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.

High ash paper | √ | ? | ? Better Hiding power |
Low ash paper | ? | √ | Better opacity |
coinage paper | ? | √ | Better opacity |

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.
