Because the difference both crystal category, usage and dosage also have different 

distinction, in commonly used white pigments, anatase ,the minimum relative density, 

chemical properties is very stable, and lower price than titanium rutile , so there is the 

certain markets in many fields of industry like the cosmetics, paints, papers and others.

 

Applications:

 

1. Characteristic requirements for titanium dioxide in coatings and paints 

 

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!

 

2. Titanium dioxide quality requirements: Plastic, PVC, masterbatch

 

requirements	effects
Hiding power	Good covering power, Lighter and Thinner to produce plastic products
Whiteness	Decide the appearance of the palstic products:light color or white color
Dispersibility	Affect the cost of plastic products production, bad dispersibility affects the  smoothness and brightness
weather resistance	The plastic products outdoors and plastic doors and Windows must ensure the weather resistance
machinability	In the production of white masterbatch (especially concentration variety), titanium dioxide machinability is the key to the production efficiency and cost.
performace impact	Titanium dioxide volume of addition affects the quality of the plastic products, Especially when larger addition.

3. Titanium dioxide quality requirements: Paper production

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.

 

3. titanium dioxide quality requirements: ink and rubber

 

Titanium dioxide , also have a wide range of applications in ink,rubber and others, including the three major application fields

 (1) Ink

Titanium dioxide is an indispensable white pigment in the senior ink, ink containing titanium dioxide color fast, good surface moisture resistant, easy to disperse, rutile type titanium pigment,both used in the printing ink industry .
Practice proved rutile type titanium pigment has ideal application performance, can be widely used in various types of ink preparation, crystal shape, refractive index and tinting strength, the index of fluorescence, type is better than the sharp titanium rutile type titanium pigment, therefore, rutile type titanium pigment is widely used in printing ink.

(2)Rubber

Titanium pigment mainly used as colorants in rubber industry, but also has a reinforcing, prevent aging, filling effect. Add titanium pigment into white and color rubber products, under the sunlight, resistant to sunlight, no crack, no color, stretching rate and resistance to acid and alkali. With titanium dioxide, rubber is mainly used for automobile tires and rubber shoes, rubber floor, gloves, sports equipment, etc., generally,anatase type. But used in automobile tyres production, add a certain amount of rutile type products, to enhance the ozone resistance and ultraviolet resistance.

 

4. Liangjiang- brandtiatnium dioxide anatase production process:

 

 

 

Anatase is a type of polymorph which becomes a rutile when it is exposed at about 915 degrees centigrade. Its color is brown to black or yellow to blue. Anatase is the rarest form of titanium dioxide, but it has almost the same properties as rutile with regards to its hardness, density, and luster. However, you can distinguish the two minerals apart by their cleavage and crystal habit. Both anatase and rutile are tetragonal in structure, but the anatase has octahedrons that share four edges forming the four-fold axis. Quartz is usually associated with streaks of anatase. Quartz plus anatase make them a popular collection for gems and mineral collectors since these minerals exhibit wonderful lusters. Anatase is also used for the white pigmentation of paints, paper, and ceramics, but it is not advisable to use it outdoors because of its lower absorption rate than rutile.
