Rutile Titanium Dioxide, Surface Treatment Rutile TiO2 Nanopowder
T689: 30-50nm, 99%
Rutile titanium dioxide surface treatment processes and surface properties of the coating to the effect of titanium dioxide, thereby affecting its performance in the application of the system, such as dispersion, weather resistance, oil absorption, gloss. Titania surface treatment process is divided into inorganic and organic process. Inorganic oxides and organic matter affected by many factors, the effect of titanium dioxide-coated surface, mainly reflected in: terms of the type of surface treatment agent, dosage, using the ratio of the temperature treatment, PH and feeding methods.
Industrially, the surface of rutile titanium dioxide-coated inorganic oxide products for the three alumina, silica and zirconia, and their precipitation in the form, amount and manner must be carefully controlled, otherwise it will affect the performance of titanium dioxide.
Rutile titanium dioxide in the refractive index is the highest common white pigment, the nature of the rutile titanium dioxide has high hiding power and tinting strength.
Inorganic surface treatment of rutile titanium dioxide were wet surface treatment, pigment particles dispersed state in the slurry will affect the coating surface modifiers. If the titanium dioxide particles are not well dispersed, not only can not achieve a continuous, uniform coating, but also affect the pigment particles scatter light, reducing optical properties and pigment and pigment, are more likely to follow the jet milling process make garments received damage and affect pigment weatherability.
