ElNECS No 236-675-5 Anatase Titanium Dioxide Uses In Rubber And Coating

Specifications:

1, Liangjiang brand- titanium dioxide anatase BA01-01( General type) sulfuric acid process, firstly, titanium mineral powder ,soluble with sulfuric acid, reaction to be hydrogen sulfate titanium. And then by hydrolysis into metatitanic acid. Finally after combustion, crushing, Finished, titanium dioxide!

2, Liangjiang brand-titanium dioxide anatase BA01-01 ( General type) appearance: white powder, insoluble in water, soluble In hot and concentrated strong acid alkali, stable chemical performance, strong tint reducing, covering power and other excellent paint performance.

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.

3. Liangjiang- brandtiatnium dioxide anatase production process:

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

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.

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!

1, Titanium dioxide quality requirements: Plastic, PVC, masterbatch

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.

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.
