types of structural fasteners

In conclusion, heavy hex structural bolts play an indispensable role in modern construction and engineering. Their robust design, high-strength properties, and versatility make them the go-to choice for securing large-scale structures. However, their proper selection, use, and maintenance are essential to ensure safety, durability, and the overall integrity of the built environment. As technology advances, it is expected that heavy hex structural bolts will continue to evolve, offering even more efficient and reliable solutions for the ever-demanding world of construction.

  • China's dominance in the production of titanium dioxide is largely due to its vast mineral reserves and advanced processing technology. With a focus on achieving a minimum purity of 98%, Chinese manufacturers are able to produce high-quality titanium dioxide that meets the stringent requirements of various industries. This commitment to excellence has helped China establish itself as a global leader in the production of titanium dioxide.
  • Prof. Matthew Wright, chair of EFSA’s working group on E171, noted: “Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods we could not rule out a concern for genotoxicity and consequently we could not establish a safe level for daily intake of the food additive.”

  • Basic Information

  • Lithopone, a crucial component in the manufacturing of various industrial products, is a mixture of zinc sulfide and barium sulfate. It is widely used as a white pigment in paints, plastics, printing inks, and many other applications due to its excellent opacity and light stability. The global lithopone market, therefore, plays a significant role in the worldwide chemical industry.
  • ≥ 5 % of standard sample

  • Lithopone, a white pigment composed of a mixture of zinc sulfide and barium sulfate, has become an indispensable ingredient in the paint industry. Its unique properties, including excellent opacity, high brightness, and resistance to weathering, make it highly valued among paint manufacturers. As the demand for sustainable and efficient paint products grows, the role of lithopone and its suppliers has become more critical than ever.


  • Many global players dominate the market for 1250 mesh suppliers, each with their unique strengths and offerings. Some specialize in specific materials, like carbon black, titanium dioxide, or zinc oxide, while others cater to a broader range of applications. It is crucial to evaluate the supplier's capabilities against the specific requirements of your industry.
  • In addition to particle size, it is also important to consider the amount of titanium dioxide used in food products

  • Titanium oxide, also known as TiO2, is a widely used inorganic compound that is found in a variety of products and applications. It is commonly used as a pigment in paints, plastics, papers, and other materials due to its excellent opacity and durability. Titanium oxide is also utilized in the production of sunscreen, as it provides a high level of UV protection.
  • This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists' pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.
