Rutile Titanium Dioxide By Sulphate Process
Property:
Titanium dioxide (or titanium dioxide) is widely used in various structural surface coatings, paper coatings and fillers, plastics and elastomers, and other uses include ceramics, glass, catalysts, coating fabrics, printing inks, roof tiles and fluxes. According to statistics, the global demand for titanium dioxide in 2006 reached 4.6 million tons, of which the coatings industry accounted for 58%, the plastics industry accounted for 23%, papermaking 10%, and other 9%. Titanium dioxide can be made from ilmenite, rutile, or titanium slag. There are two production processes for titanium dioxide: sulfate process and chloride process. The technology of the sulfate method is simpler than that of the chloride method, and it can be used for low-level and cheaper minerals. Today, about 47% of the world's production capacity uses the sulfate process and 53% of the production capacity is the chloride process.
The chemical properties of titanium dioxide are extremely stable, and it is a slightly acidic amphoteric oxide. It hardly reacts with other elements and compounds at room temperature, and has no effect on oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, and sulfur dioxide. It is insoluble in water, fat, dilute ACID , inorganic acid and alkali, and only soluble in hydrogen. Fluoric acid. But under the action of light, titanium dioxide can undergo continuous oxidation-reduction reactions and has photochemical activity. This kind of photochemical activity is particularly obvious under ultraviolet irradiation. This property makes titanium dioxide a photosensitive oxidation catalyst for some inorganic compounds and a photosensitive reduction catalyst for some organic compounds.
Rutile grade Titanium Dioxide is manufactured by the sulfate process and supplied as a fine, dry powder, which is inorganic coated with Zr&Si and special organic surface treated to have both good optical properties and excellent pigment properties.With advanced control technology of particle-size and particular coating technology, the product shows good whiteness,high gloss, great hiding power, strong tinting power, favorable weatherability, high chalk resistance, low oil absorption, good wetting and is easy to disperse in a variety of systems.So it's widely used in painting, printing oil, paper making, plastic PVC, masterbatch, rubber, artificial fiber, welding electric, enamel, electric appliances and construction material etc.
For paint or Coating,Except Titanium Dioxide,we also supply Iron Oxide pigments, Carbon Black Pigment, Sodium Hexametaphosphate 68%, Chrome Oxide Green, Chrome Yellow, Sodium Tripolyphosphate 94%, C9 Petroleum Resin, Caustic Soda Flakes,Formic Acid 85% etc.
