Titanium Dioxide

详情

Chemical properties:
White powder.
Quality of a material soft odorless tasteless white powder, covering power and good dyeing force, at ***0 ~ ***0 ℃ solution. Not soluble in water, dilute inorganic acid, organic solvents, oil, slightly soluble in alkali, soluble in strong sulfuric acid. Encounter heat to become yellow, cooling and become white. Rutile type (R type) 4.*6 g/cm3 density, refractive index of 2.*2. R type of titanium dioxide has better resistance to climate sex, resistance to water and not easy to change the characteristics of yellow, but the white degree is a bit poor. Sharp titanium type (type A) 3.*4 g/cm3 density, refractive index of 2.*5. Type A white light resistance sex differences, not weathering resistance, but whiteness is better. In recent years found to the nanometer level superfine titanium dioxide (usually of *0 to *0 nm) has the properties of semiconductor, and high stability, high transparency, highly active and high dispersion, non-toxic and color effect.
Product use:
Used to paint, ink, plastic, rubber, paper making, chemical fiber and other industries; Used for welding wire, extract the titanium and titanium dioxide manufacturing titanium dioxide (to the nanometer level) is widely used in functional ceramics, catalyst, cosmetics and photosensitive material, etc
White inorganic pigment. Is white pigment in the strongest tinting a, with excellent covering power and color fastness, apply to opaque white products. Rutile type especially suitable for outdoor use plastic products, can give products good light stability. Sharp titanium type used mainly for indoor use products, but with a slight blue, white degree is high, covering power is big, strong tinting and dispersivity is good. White is widely used as a paint, paper, rubber, plastic, enamel, glass, cosmetics, printing ink, watercolor and paints paint, also can be used in metallurgy, radio, ceramics, welding wire
