Titanium dioxide's third-largest user in papermakingindustry.(10% of the amount of titanium dioxide)

Because of considering the cost of production in general will notuse titanium dioxide in low-grade paper, the main use of porcelain clay, talc,calcium carbonate, etc., but they will reduce the strength of paper, increasethe weight of the paper.

Decorative paper, bible paper, and paper must be used in thetitanium dioxide (such as dictionaries, posters, magazine covers, computer,money, copier paper and decorative paper, etc.)Effect:Good whiteness, highstrength, luster, thin and smooth, does not penetrate when printing,Under thecondition of same opacity 10 times higher than the calcium carbonate and talcumpowder, weight can reduce 15% ~ 30%.

Decorative paper also called titanium white paper, is mainly usedfor making furniture, floor, wallpaper and raw materials.The covering power ofrutile type titanium dioxide, so in high ash used in the paper of rutile typetitanium dioxide.

Requirement for the quality of titanium dioxide papermaking industryas follow:

1.Covering power:High covering power of titanium dioxide, the priceis high, less dosage, so the cost of every tons of titanium dioxide in the papermay lower;Covering power is low titanium pigment, although the price is low,but the amount is big, leads to the higher costs per ton paper in titaniumdioxide;

2.Whiteness:Titanium dioxide’s whitenessdecide the appearance of the paper;

3.Dispersibility:Now the paper making process is generally use ofdispersants, therefore, titanium dioxide’s waterdispersion difference is small;

4.weather ability:Rutile type titanium dioxide can satisfy mostweather resistance requirements of paper;

5.Retention:Paper making industry was carried out on the filtrationof water reuse, or with retention agent, titanium dioxide recovery rate of 99%or more commonly, preserve the index, because the international big company oftitanium white in pushing the paper special titanium white both at the sametime provide retention agent formula and method of use, in order to improve theservice quality, increase product competitiveness.

Factors influencing the quality of decorative base paper:

Absorption performance, strength, whiteness and cover, smoothness,and evenness.
