3, Comparation of chlorination process VS. Sulfuric acid process rutile titanium dioxide produced by Liangjiang:

 

 

 

4. Sulfuric acid process titanium dioxide

Advantages: use cheap titanium ore (or titanium slag) and sulfuric acid as the main raw materials, of long-history technology, proven technique and low production cost.

Disadvantages: process, long process, serious pollution to the environment, low product quality stability

 

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.

4. Titanium dioxide anatase, titanium dioxide antase coated, titanium dioxide rutile sulfuric process, titanium dioxide rutile chlorination process:

This table shows the Liangjiang Brand chlorination process rutile titanium dioxide R920 has the highest refractive index, the highest hiding power (opacity) and achromatic force, bright whiteness, high gloss and good dispersion.

 

Applications:

 

 

1. Characteristic requirements for titanium dioxide in coatings and paints

 

Item	Building Coat
	Normal temperature drying enamel paint (Little porcelain paint type)	emulsion coatings
Outdoor	weather resistance, Hiding power, aesthetic property	weather resistance, Hiding power, aesthetic property( Little outdoor)
Indoor	Hiding power, aesthetic property	Hiding power, aesthetic property
Item	Industrial Coat
	automobile	home electrical appliances
Finish coat	weather resistance, Hiding power, aesthetic property , dispersibility	Hiding power, aesthetic property
floating coat	weather resistance, Hiding power, dispersibility
primer coat	dispersibility

 

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!

 

2. 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.

 

3. Titanium dioxide quality requirements for paper production:

 

classification	Tio2  classification		Notes
	rutile	anatase
decorative paper	√		Higher Anti-aging requirement
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.

 

4. Titanium dioxide quality requirements for 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.
