  • 4. The average flow rate of the pipeline is too low, and the average flow rate of the pipeline is lower than the critical settlement deceleration, resulting in pipeline blockage and unable to transport slurry normally. Through the above examples, it can be seen that the selection of ZJ series slurry pump is more complicated, and if any link makes a mistake, it may lead to the mistake of the entire selection, causing irreparable losses to users, and having an adverse impact on their reputation. Therefore, in the selection, we must pay attention to the values of several key coefficients and calculate them carefully to achieve accuracy, so that the ZJ series slurry pump can fully reflect its advantages in field application.

  • Top 10 Chinese TiO2 exporters in 2016

  • The year 2016 had shown a strong rebound of China’s TiO2 business in general, according to market intelligence firm CCM. The market situation in 2015 was quite depressed, while in 2016 huge price rises have benefited the financial performance of China’s manufacturers.

  • Both rutile and anatase titanium dioxide factories require strict quality control measures to ensure the purity and consistency of the final product. The production processes involve several stages, including raw material preparation, chemical reactions, particle formation, and finishing. Each stage must be carefully monitored and controlled to ensure the desired properties of the final product.
  •                Rutile Grade Titanium Dioxide 2377 CAS 13463-67-7

  • Titanium dioxide (TiO2) is by far the most suited white pigment to obtain whiteness and hiding power in coatings, inks and plastics. This is because it has an extremely high refractive index and it does not absorb visible light. TiO2 is also readily available as particles with the right size (d ≈ 280 nm) and the right shape (more or less spherical) as well as with a variety of post-treatments.

    However, the pigment is expensive, especially when the volume prices of systems are used. And, there always remains a need to develop a full-proof strategy to obtain the best results in terms of cost/performance ratio, scattering efficiency, dispersion… while using it in coating formulations. Are you searching for the same?

    Explore the detailed knowledge of TiO2 pigment, its scattering efficiency, optimization, selection, etc. to achieve the best possible white color strength and hiding power in your formulations.

  • One of the most common worries about titanium dioxide is that it could be a cancer-causing agent. The link between cancer and titanium dioxide traces back to a 1985 study where rats were exposed to high levels of titanium dioxide for two years, causing lung cancer. However, not all experts are convinced by this study.

  • 5. Cristal Cristal is a leading manufacturer of TiO2, with production facilities located in the Middle East and Africa. The company offers a wide range of TiO2 products, including rutile, anatase, and speciality grades, catering to the needs of different industries. Cristal is committed to sustainability and has implemented several environmental initiatives to reduce its carbon footprint.
  • Manufacturers must also consider the particle size distribution of titanium dioxide when formulating their products. Finer particles can lead to improved gloss and smoothness, while coarser particles might be preferred for specific textured effects or to reduce costs without compromising on opacity. The surface treatment of titanium dioxide particles is another aspect that can be tailored to enhance compatibility with different types of binders and additives used in paint formulations.
  • One of the key factors that influence the quality of lithopone is its raw material composition. We carefully select high-quality barium sulfate and zinc sulfide as the main components, which are essential for the formation of the desired crystal structure and chemical properties of lithopone. To further enhance the performance of lithopone, we also add certain additives during the production process.

  • Among the raw materials for coating production, titanium dioxide is more ideal, followed by lithopone. The covering power of lithopone is only that of titanium dioxide, and the price of lithopone is much lower than that of titanium dioxide, so lithopone still occupies a large market share.

  • In a study published in 2022 in the journal Particle and Fibre Technology, researchers examined the impact of maternal exposure to titanium dioxide nanoparticles in newborn offspring mice. They found that “a chronic exposure to TiO2 NPs during pregnancy alters the respiratory activity of offspring, characterized by an abnormally elevated rate of breathing.” Breathing was also shown to be “significantly and abnormally accelerated,” and the ability for neural circuitry to effectively adjust breathing rates was impaired. The researchers concluded: “Our findings thus demonstrate that a maternal exposure to TiO2 NPs during pregnancy affects the normal development and operation of the respiratory centers in progeny.”

  • At present, the domestic wet zinc smelting mainly adopts the roasting-leaching-electrowinning production process, and the zinc content in the acid leaching residue is generally 8-15%, some up to 20%, and the sulfur mass fraction is 6-12%, of which sulfuric acid The root mass fraction is 15-30%, mainly in the form of 0^0 4 (in this ammoniatic environment, the leaching rate of sulfate leaching in multiple stages can reach 70%). The zinc in the acid leaching residue is mainly in the form of ZnFe 2 0 4 . In order to recover these zinc, the treatment methods are currently available in the fire method and the wet method. The fire method is the rotary kiln evaporation method (Wilz method) and the fumigating furnace evaporation method. . The wet method has hot acid leaching or high temperature pressure leaching. The fire treatment process is long, the equipment maintenance is large, the investment is high, the working environment is poor, and a large amount of coal or metallurgical coking coal is consumed, which has low efficiency and large environmental pollution. Therefore, it is usually leached by hot acid or high-pressure leaching. These methods still have the disadvantages of: 1 consumption of a large amount of acid, low leaching rate, due to the large amount of calcium sulfate, calcium sulphate and other ultrafine particles to isolate the zinc oxide particles, resulting in Electrolytic zinc enterprises are difficult to leach in acid environment, and the second weak acid leaching is not meaningful because the recovery rate is too low. 2 If leached with strong acid, although ZnFe 2 0 4 is destroyed, the leaching rate is improved, but the iron leaching rate is also high (up to 60%). The pressure of iron removal is large, and more reagents are consumed. 3 High temperature and high pressure equipment is corroded. Serious, complicated equipment investment; 4 high operating costs, poor economic returns. 5 The last slag discharged is acid leaching residue, which brings new pollution to the environment. It has to be cured and landfilled, which not only pollutes the environment, but also wastes resources.
  •  In summary, for the treatment of electrolytic zinc acid leaching slag, how to overcome the shortcomings of traditional fire and wet methods, effectively leaching zinc in low-zinc content materials, and obtaining nano-scale lithopone, becoming the industry A technical problem that needs to be solved and cannot be solved.
