2. 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.

Applications:
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.
we aspires to be the supplier of the world's leading chemical raw
materials, show our value of the products made in China!
