Color Masterbatch Grade Chloride Process Titanium Dioxide Tio2 Cas No.13463-67-7

Tio2 Cas No.13463-67-7 Color Masterbatch grade Chloride Process Titanium Dioxide

 

 

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.

Description:

 

1, Liangjiang Brand rutile titanium dioxide R920 is manufactured through chlorination process, using high-quality titanium ore as the main raw material, after chlorination, refining, oxidation and surface treatment.

 

2, Liangjiang Brand rutile titanium dioxide R920 is coated with ZrO2, Al2O3 and special organic treatment. The features are of neutral hue, high gloss, high weatherability, high covering power, excellent dispersion, etc. With excellent resistance to pulverization, our R920 can substitute other high-grade titanium dioxide products like Dupont R902.

 

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

 

 

 

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.
