Problems solved by technology
[0004] The surface treatment pot is the main equipment in the titanium dioxide coating process. The traditional surface treatment pots are all flat bottoms, so that there will be dead corners in the pot during operation, and the coating cannot be guaranteed evenly. Therefore, many domestic and foreign manufacturers are concerned about this. Research was carried out and the result is that there are still dead spots in the surface treatment pot when stirring

Embodiment Construction
[0046] like figure 1 As shown, the upper part 2 of the surface treatment pot is in the shape of a cylinder, and the bottom 1 is in the shape of an inverted cone, wherein the angle of the cone is 100°-130°, and the optimum angle is 120°. The large flow and low axial flow pump is used to tangentially feed the material into the upper part 2 of the surface treatment pot. During the operation, there is no dead angle in the pot, and the coating is uniform at the same time.
[0047] A kind of rutile titanium dioxide, the surface of titanium dioxide is coated with inorganic coating material and organic coating material. The coating material is a surfactant.
[0048]The rutile-type titanium dioxide is subjected to inorganic surface treatment and organic surface treatment successively in a surface treatment pot with an inverted cone shape at the bottom to obtain products with different performances and uses. The treated rutile titanium dioxide includes hydrophobic titanium dioxide and...

The invention discloses rutile type titanium dioxide. The surface of the rutile type titanium dioxide is compounded and coated with an inorganic coating material and an organic coating material, wherein the inorganic coating material is one or a mixture of several of oxides of aluminum, silicon, titanium and zirconium, and the organic coating material is a surfactant. The rutile type titanium dioxide comprises hydrophobic titanium dioxide and hydrophilic titanium dioxide. The invention also discloses production equipment of the rutile type titanium dioxide, which comprises a surface treatment pot of which the bottom has an inverted-cone shape. Through improvement of the equipment, the coating rate reaches more than 98 percent and the coating is uniform and high in compactability. The compound coating improves the whiteness, brightness and non-transparency of the rutile type titanium dioxide, the dispersivity, lubricity, fluidity and wear resistance of the rutile type titanium dioxide during the preparation of paint, and the stability of rutile type titanium dioxide in stored products.
Description
technical field [0001] The invention relates to a chemical product and its production equipment, in particular to titanium dioxide and its production equipment. Background technique [0002] Titanium dioxide has a slight light absorption in the ultraviolet band below 405nm wavelength. Theoretically, it can prolong the life of coatings and plastics after absorbing ultraviolet light, but at the same time it has photochemical activity. Oxygen atoms emitted by light irradiation will oxidize and degrade the organic medium such as the coating film, so that the coating will lose its luster, and white powder will be separated from the surface of the film, and then eroded by the atmosphere, the coating film will crack and peel off, that is, it will age , the coating film will also turn yellow, and when titanium dioxide is mixed with color pigments, it will cause floating and blooming. If it is treated by surface treatment, the phenomenon of discoloration and fading will be obviously ...
