Titanium Dioxide R-248: a sulfuric acid production process using rutile titanium dioxide. By zirconia and alumina inorganic surface, surface modified with a special organic treatment agent, has blue phase, easy to disperse, high durability, high hiding power, low oil, a good system compatibility, excellent processing rheology and other characteristics, is an oily, high-quality plastic and titanium white. It can be widely used in polyolefins, PVC, ABS, PS and other masterbatch, profiles, sheet, pipe, and can also be used for making leather paste, oil paint. Technical requirements Index name technical requirements titanium dioxide content% ≥95.0% ≥94.0 105 ℃ brightness volatile matter% ≤0.8 pH value of an aqueous suspension of oil absorption capacity of 6.0-9.0 g / 100g ≤19 sieve residue (45μm sieve)% ≤0.02 achromatic force. Reynolds number ≥1800 rutile content% ≥96 aqueous extract resistivity Ωm ≥60 Whiteness (compared with standard sample) not less than dispersion. Hagerman number ≥5.00 application features blue bottom phase: the average particle size of the R-248 is close to the theoretical optimum particle size of titanium dioxide, the small particle size of TiO2 is more effective than the large particle scattering blue light, so it has more blue The bottom phase and excellent whiteness. Excellent dispersion: a special surface treatment of inorganic and organic surface treatment reduces the contact between the TiO2 particles, so that R-248 in the application process showed excellent dispersion. Thus wetting, easy grinding. Low oil: R-248's low oil, so maintaining good processing properties of titanium dioxide in the application process in the plastic. High weather resistance: R-248 treatment process using coated zirconium, titanium dioxide improved weather resistance and heat resistance, chemical resistance and therefore very stable. A good system compatibility: R-248 specific organic surface treatment, is very suitable for non-polar systems and oil system, and thus in the application show a good system compatibility. Uses Titanium Dioxide R-248 can be widely used in plastics, masterbatch, inks and other fields. Packaging: 25 kg bag or paper-plastic hybrid 500,1000 kg plastic bags. Product Storage: Just avoid damp, long-term storage. Safety: In dealing with TiO2, should wear gloves and protective cover. If skin contact, the compound is not in danger, but it is recommended to use the skin after cleansing.
