Description:

The paper is the third largest titanium dioxide users.Low-grade paper because of considering the cost of production in general will not use titanium dioxide, the main use of porcelain clay, talc, calcium carbonate, etc., but they will reduce the strength of paper, increase the weight of the paper.Decorative paper, bible paper, and paper (such as dictionaries, posters, magazine covers, computer, money, copier paper and decorative paper, etc.) must be used in the titanium pigment, use white paper, good whiteness, high strength, luster, thin and smooth, not penetrate when printing, under the condition of same opacity 10 times higher than the calcium carbonate, talcum powder and weight can reduce 15% ~ 30%.

Decorative paper also called titanium white paper, is mainly used for making furniture, floor, wallpaper and raw materials.Sheets of paper to the requirement of has anti-aging, must use rutile;More rutile is used in high ash in the paper, the high ash in paper must use rutile, because of the sharp titanium type titanium white cover is put less than required.Sharp titanium type titanium white in low ash in the paper, such as bible paper and paper, bible paper request paper has good opacity, general use sharp titanium type titanium white can meet;Coinage paper also requires good opacity, mainly use sharp titanium type.At home, the use of decorative paper titanium white volume is much higher than the other two varieties, this kind of situation is determined by the level of consumption of our country.Due to the huge demand for housing decoration, high-grade furniture, decorative paper consumption rising;Bible paper due to the use of titanium white as raw materials, the cost is much higher than ordinary paper, in view of the domestic consumption level, the bible paper market is limited;The coin paper and using more is controlled by the state, the dosage is relatively stable, will not affect the market of titanium white.According to incomplete estimates that domestic used in decorative paper each year more than 30000 tons of titanium white.Dosage of decorative paper in titanium white 20 ~ 40%, other titanium white 1 ~ 5% in the paper.Due to the culture of traditional paper production factories have transformation decorative paper, decorative paper production increase quickly, the price of decorative paper is on the decline in recent years.

Applications:

1.    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.

2. 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.
