Paper making is the third largest user of titanium dioxide industry. Low - grade paper because of the cost of production, generally do not use titanium dioxide as raw material. Mainly with clay, talc, calcium carbonate as raw materials for paper, reduce the strength of paper, increase the weight of paper. But decorative paper, bible paper, dictionaries, posters, magazine covers, computers, coins, copy paper, decorative paper and other banknotes must use titanium dioxide. Titanium dioxide ensures good whiteness and excellent strength, gloss, smoothness and impermeability of the paper. Paper made from titanium dioxide is 10 times more opaque than paper made from calcium carbonate and talcum powder, and weighs 1,530 less, all the same conditions.
Titanium dioxide paper is mainly used in the production of furniture, flooring and wallpaper raw materials. For paper with anti-aging requirements, you must use rutile titanium dioxide. High ash paper with rutile, high ash paper must use rutile, because the opacity of anatase titanium dioxide can not meet the requirements of anti-aging. Anatase type titanium dioxide is used in low ash paper such as Bible paper and paper money. Biblical paper requires paper with good opacity, so general anatase type titanium dioxide can meet the need. Paper money requires the same paper properties as bible paper, so anatase type titanium dioxide is commonly used. The titanium dioxide dosage of domestic decorative paper is far higher than the above two varieties, this is decided by the consumption level of our country.
