Production method of titanium dioxide and photocatalytic self-cleaning ceramic
The invention discloses a production method of titanium dioxide and photocatalytic self-cleaning ceramic. The production method comprises the following steps: (1) carrying out acidolysis reaction on high-phosphorus titanium ore to prepare a TiOSO4 solution; (2) adjusting the TiOSO4 solution by using distilled water, controlling the concentration of the TiOSO4 solution, carrying out hydrolysis reaction to prepare a hydrated titanium dioxide precursor, and controlling the phosphorus content in the hydrated titanium dioxide precursor to be 0.2-0.3%; (3) primary washing; (4) secondary washing; (5) pulping; (6) adding SiO2 into the pulped slurry, uniformly stirring, and filtering to obtain a filter cake; and (7) drying and crushing the filter cake. The method has the beneficial effects that the mineral source with high phosphorus content is selected as the raw material, the phosphorus content in the final finished product is increased, the rutile conversion temperature of the product is increased, the conversion rate of titanium dioxide rutile after the porcelain is fired at high temperature (gt, 1000 DEG C) is reduced, and the influence of the reduction of the antibacterial activity of the titanium dioxide rutile is reduced to the minimum.
本发明公开了二氧化钛及光催化自清洁陶瓷的生产方法，包括以下步骤：（1）、采用高磷钛矿进行酸解反应制备TiOSO4溶液；（2）、使用蒸馏水调节TiOSO4溶液，控制TiOSO4溶液的浓度进行水解反应制备水合二氧化钛前驱物，所述水合二氧化钛前驱物中磷含量控制在0.2%‑0.3%；（3）、一洗；（4）、二洗；（5）、打浆；（6）、向打浆后的浆料中加入SiO2，搅拌均匀后，过滤成滤饼；（7）、将滤饼干燥，粉碎。本发明的有益效果是选用磷含量高的矿源作为原材料，提高最最终成品中的磷含量，提高产品的金红石转化温度，降低瓷经过高温（>1000℃）烧制后二氧化钛金红石的转化率，使其抗菌活性会降低的影响降至最低。
