economical Tio2 pigment Anatase Titanium Dioxide for Masterbatch CAS 13463 67 7

economical Tio2 pigment Anatase Titanium Dioxide for Masterbatch CAS. 13463-67-7

 

1. Specifications:

 

titanium dixoide anatase , mainly has the following several aspects: Using in paper , generally without the surface treatment, the effect of fluorescence, whitening, increase the whiteness of the paper. Usig in ink, Both type,anatase and rutile, is the indispensable white pigment. Using inTextile and chemical fiber industry , manily as matting agent, due to the softness of anatase than the rutile type, generally use anatase. Using in rubber, as colouring agent,reinforcing, prevent aging, filling effect, general use anatase type.

 

Titanium dioxide, stable chemical properties. It is a kind of partial acid amphoteric oxide,does not react with other elements and compounds at normaltemperature, doesn't work for oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, sulphur dioxide, insoluble in water, fat, also in dilute acid and inorganic acid, alkali, only soluble in hydrofluoric acid.But under the effect of light, titanium pigment, can occur continuous REDOX reaction and has the photochemical activity.This kind of photochemical activity, particularly under ultraviolet light sharp, this nature make titanium dioxide even some inorganic compounds photosensitized oxidation catalysts, and some organic compounds photosensitive reduction catalyst.

4. Titanium dioxide compared with other kinds of white pigment:

 

Name	Relative Density	Refractive index	Tint reducing		hiding power
			Reynolds number	relative value
Tiatnium dioxide rutile Chlorination process	4.0	2.85	1800	105	105
Tiatnium dioxide rutile sulfuric process	4.2	2.76	1650	100	100
Titanium dioxide anatase	3.91	2.55	1270	77	78
Barium sulfate	4.5	1.64
zinc oxide	5.6	2.02	200	12	14
lithopone	4.2	1.84	260	16
BasicLeadCarbonate	6.1	2	150	9	12
zinc sulfide	4	2.37	660	40	39

From this table, titanium dioxide rutile compared with titanium dioxide anatase, 
relatively lack of surface treatment technology. To the high weatherability products, 
can only use the rutile type; To the lower weatherablility, higher whiteness, 
titanium dioxide anatase is the best choice.

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

 

	Titanium dioxide anatase	titanium dioxide antase coated	titanium dioxide rutile sulfuric process	titanium dioxide rutile chlorination process
Powder type	Indoor powder	Indoor powder	Indoor /outdoor powder	Indoor /outdoor powder
Using quantity	More	seldom	More	Less

According to the requirements of the coating properties, to choice the satisfied for the coatings and 

coating properties is very important. From the table, with the chlorination process rutile type titanium 

pigment production product is the best, currently we could see rutile chlorination is the best white 

pigement on the market . The comprehensive performance is excellent, the first choice in the white 

pigments, also the necessary pigment in light color.Because of the different surface treatment 

technology, titanium dioxide has different models. According to the characteristics of the mixture of 

coating, such as the high gloss, high covering power, or high pulverization, to choice the relevant type.

Rutile sulfuric acid process, due to the conversion rate of anatase to rutile is lower than chlorination 

process, so the whiteness of the product and the stability of the light from chlorination process is a 

bit difference, but the price is lower.

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. 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.

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.
