  • Sulphate process. The ilmenite is reacted with sulphuric acid giving titanium sulphate and ferric oxide. After separation of ferric oxide, addition of alkali allows precipitation of hydrous titanium dioxide. The washed precipitate is calcined in a rotary kiln to render titanium dioxide. The nucleation and calcination conditions determine the crystalline structure of titanium dioxide (e.g. rutile or anatase).

  • At present, the equipment and manufacturing process of domestic manufacturers of polyvinyl butyral are constantly getting closer to those abroad. For example, the wonderful use of polyvinyl butyral (PVB) has occurred in the printing industry and ceramic industry. Therefore, the domestic application of polyvinyl butyral (PVB) has an obvious upward trend in recent years.

    For example, in the glass industry, it is because polyvinyl butyral (PVB) has good low-temperature impact strength, windability, light transmittance, light resistance, weather resistance, sound insulation, UV insulation and other properties, so that once the laminated glass is sealed together, the glass sandwich (i.e. laminated material) will appear as a whole and look like ordinary glass. For example, in the porcelain industry, polyvinyl butyral is made into a film and used for printing paper film of ceramic (or enamel) products. First, it reduces the original glue small paper Decal process, reduces the production cycle and production cost, and second, it makes its ceramic (or enamel) patterns bright in color and smooth in texture.

    With the rapid development of science and technology in recent years, more and more industries have found the characteristics of polyvinyl butyral (PVB): high strength, high toughness, fatigue resistance, corrosion resistance and so on. Compared with traditional materials, polyvinyl butyral (PVB) is more and more widely used because of its larger development space and wider application fields!

    Application field of polyvinyl butyral -- safety glass

    The membrane made of polyvinyl butyral (PVB) is a special product used to manufacture safety glass and bulletproof glass. Safety glass is a special glass made of a layer of PVB diaphragm sandwiched between two layers of ordinary glass. It has good low-temperature impact strength, windability, light transmittance, light resistance, weather resistance, sound insulation, ultraviolet insulation and other properties. When subjected to strong external impact, PVB diaphragm can absorb impact energy, so that the glass will not break or prevent debris from hurting people. Moreover, the safety glass added with PVB diaphragm has the characteristics of high transparency, water resistance and aging resistance, and can be used in the environment of - 60 ℃. In addition, it can also be used as transparent material to replace plexiglass.

  • China has emerged as a global leader in the production of rutile titanium dioxide, a crucial pigment used in a wide range of applications, including paints, plastics, and coatings. With its vast reserves of rutile ore and advanced manufacturing capabilities, China has been able to establish a strong foothold in this sector, overtaking traditional producers such as Australia and South Africa.
  • Good whiteness titanium dioxide rutile is a critical component for coating factories due to its exceptional optical properties. The term good whiteness refers to the pigment's ability to reflect a broad spectrum of visible light, resulting in a bright, clean appearance. This characteristic is particularly important in applications where a uniform and consistent color is desired, such as in paints, plastics, and paper manufacturing.

  • China, as a global manufacturing hub, plays a significant role in the production and pricing of various industrial materials, including lithopone pigments. Lithopone, a versatile white pigment, is widely used in industries like coatings, plastics, printing inks, and paper due to its excellent whiteness, opacity, and cost-effectiveness. It is a combination of zinc sulfide and barium sulfate, offering a cost-efficient alternative to titanium dioxide.

  • Another important consideration when selecting a supplier is their reliability and consistency in delivering high-quality materials

Suppliers should have robust quality control measures in place to maintain the quality and consistency of their products.
  • It’s true that titanium dioxide does not rank as high for UVA protection as zinc oxide, it ends up being a small difference (think about it like being 10 years old versus 10 years and 3 months old). This is not easily understood in terms of other factors affecting how sunscreen actives perform (such as the base formula), so many, including some dermatologists, assume that zinc oxide is superior to titanium dioxide for UVA protection. When carefully formulated, titanium dioxide provides excellent UVA protection. Its UVA protection peak is lower than that of zinc oxide, but both continue to provide protection throughout the UVA range for the same amount of time.
