  • The calcined product obtained by the ordinary zinc-barium white preparation method is beaten into a slurry, which is then surface-treated with sodium silicate, aluminum sulfate or sodium aluminate and surfactant, and then filtered, washed, dried and pulverized. Can.

  • China has emerged as a pivotal player in the global titanium dioxide industry, with its importers playing a crucial role in shaping the dynamics of this sector. Titanium dioxide, also known as TiO2, is a white pigment widely used in various applications such as paints, plastics, paper, and cosmetics. The country's growing demand for this versatile compound has led to an increase in import activities, making Chinese importers a vital link between domestic consumers and international producers.
  • Having thus described the origin and uses of the pigment, we now come to the question, what is lithopone? It is, in short, a chemical compound usually consisting of 30.5 per cent zinc sulphide, 1.5 per cent zinc oxide and 68 per cent barium sulphate, but these proportions vary slightly in the different makes. Lithopone of this composition is sold as the highest grade, either as red seal or green seal, as it best suits the idea of the manufacturer. Many manufacturers, especially in Europe, sell and also export other brands under other seals, containing 24, 20, 18 and as little as 12 per cent of zinc sulphide with very small percentages of zinc oxide, the balance being usually barium sulphate, but sometimes certain portions of China clay or gypsum (calcium sulphate) or whiting (calcium carbonate). Such brands are not a chemical compound, but mechanical mixtures of the chemically compounded lithopone and the admixtures referred to.

  • For research published in 2022 study in the journal Food and Chemical Toxicology, scientists examined “the genotoxicity and the intracellular reactive oxygen species induction by physiologically relevant concentrations of three different TiO2 nanomaterials in Caco-2 and HT29-MTX-E12 intestinal cells, while considering the potential influence of the digestion process in the NMs’ physiochemical characteristics.” They found a “DNA-damaging effect dependent on the nanomaterial,” along with the micronucleus assay suggesting “effects on chromosomal integrity, an indicator of cancer risk, in the HT29-MTX-E12 cells, for all the tested TiO2 nanomaterials.” Researchers concluded that the results showcase “evidence of concern” regarding titanium dioxide used as a food additive.

  • The stability of R-906 rutile titanium dioxide under various printing conditions is another factor contributing to its popularity among ink suppliers. Whether used in offset, flexographic, or gravure printing processes, this pigment maintains its color strength and clarity without fading or discoloration Whether used in offset, flexographic, or gravure printing processes, this pigment maintains its color strength and clarity without fading or discoloration Whether used in offset, flexographic, or gravure printing processes, this pigment maintains its color strength and clarity without fading or discoloration Whether used in offset, flexographic, or gravure printing processes, this pigment maintains its color strength and clarity without fading or discolorationprinting ink grade rutile titanium dioxide r-906 supplier. Moreover, its chemical resistance prevents reactions with other components of the ink, ensuring long-term reliability and reducing the risk of spoilage.
  • Importantly, TiO2 also has a very high refractive index (its ability to scatter light), even higher than diamond. This makes it an incredibly bright substance and an ideal material for aesthetic design use.

  • R-996 titanium dioxide, white powder, insoluble in water, non-physiological toxicity, chemically stable, with excellent weather resistance and anti-powdering ability.

  • TiO2 absorbs UV light. This property makes it appear bright white under light, unlike other white materials that can look slightly yellow.
