Concrete form wedge bolts are specialized bolts designed for use in concrete formwork systems. They typically feature a tapered design that allows for easy insertion and a secure grip once fitted. The wedge shape creates a locking mechanism that holds the formwork in place, preventing it from moving during the pouring process. These bolts are often made from high-strength steel to withstand the pressures and forces exerted by wet concrete, making them reliable for various construction applications.

  • Lithopone has therefore traditionally been used in stoppers and putties, jointing compounds and sealing compounds, primers and undercoats and in road-marking paints.

  • 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.

  • China is a leading producer and exporter of calcium carbonate and titanium dioxide, two important industrial minerals used in a wide range of applications. Both minerals are crucial ingredients in many industrial processes, but they have different properties and applications.
  • Brilliant

  • 5. Is EFSA banning titanium dioxide? 

  • Titanium dioxide is used a food colour (E171) and, as with all food colours, its technological function is to make food more visually appealing, to give colour to food that would otherwise be colourless, or to restore the original appearance of food. Titanium dioxide is also present in cosmetics, paints, and medicines.

  • For his part, Kaminski argues most of the studies have been in animals, and any effects found were minuscule. He and his team also contested some of the findings in a 2019 study that found no evidence of increased inflammation or changes in the GI tract.

  • Overwhelmingly, research that’s relevant to human eating patterns shows us that E171 is safe when ingested normally through foods and drugs (1,2).

  • All in all, Titanium Dioxide is a famous sunscreen agent and for good reason, it gives broad spectrum UV protection (best at UVB and UVA II), it's highly stable, and it has a good safety profile. It's definitely one of the best UV-filter agents we have today, especially in the US where new-generation Tinosorb filters are not (yet) approved. 

  • Early manufacturing processes often involved calcination of ilmenite or rutile, which were energy-intensive and sometimes produced inconsistent quality. However, with advancements in technology, manufacturers have refined their techniques to produce higher purity anatase TiO2 through methods like the sulfate process and the chloride process. These improvements have led to more efficient production and a better quality end product.
  • Suppliers play a crucial role in transforming these raw materials into usable titanium dioxide. They employ specialized extraction techniques such as the Becher process for ilmenite or the sulfate process for rutile and anatase, which involve chemically treating the ore to produce titanium dioxide. In the sulfate process, for example, the ore is treated with sulfuric acid to form titanyl sulfate, which is then calcined to yield titanium dioxide.
  • Titanium dioxide, a white inorganic compound with the chemical formula TiO2, is a staple ingredient in many industries. As a CL 77891 titanium dioxide supplier, we understand the importance of this versatile material and strive to provide our customers with high-quality products that meet their diverse needs.
  • Lomon's R-996 rutile titanium dioxide is meticulously refined to achieve a purity level that is second to none. Its unique crystal structure provides an outstanding refractive index, making it an ideal choice for various industries including coatings, plastics, paper, and even cosmetics. The pigment's ability to scatter light effectively imparts a brilliant white shade, enhancing the visual appeal of the end product.

  • High Scattering Power TiO2 DongFang R5566

  • The produced barium sulfide enters the leacher, and the temperature is controlled above 65°C to obtain a barium sulfide content of 70%, and then enters the clarification barrel, add zinc sulfate for reaction after clarification, control the zinc sulfate content to be greater than 28%, pH=8~9, and obtain a mixture of barium sulfate and zinc sulfide with a density of 1.296~1.357 g/cm3.

  • Overall, r 996 titanium dioxide suppliers have established themselves as reliable and reputable sources for this essential pigment. With their high-quality products, reliable supply chain, competitive pricing, and excellent customer service, businesses can rely on these suppliers for all their r 996 titanium dioxide needs. Partnering with r 996 titanium dioxide suppliers is a smart choice for businesses looking to enhance their production processes and deliver top-quality products to their customers.


  • Thirdly, the supplier's pricing and delivery terms should also be taken into consideration
  • Selecting the right zinc sulfide (ZnS) supplier is crucial for ensuring the quality and performance of products made with this versatile compound. By considering factors such as purity, particle size and shape, sustainability, price, and customer service, manufacturers can find reliable suppliers who can meet their needs while prioritizing sustainability.
  • In electronics, TiO2 finds application in solar cells due to its ability to absorb light and facilitate electron transferuse of tio2. Researchers are continuously exploring ways to enhance its efficiency, potentially leading to more cost-effective renewable energy solutions.
  • Moreover, TIO2's contribution extends beyond color enhancement. It introduces a corrosion-resistant barrier within paints, safeguarding underlying surfaces from the detrimental effects of moisture, chemicals, and UV radiation. This protective quality is of paramount importance for exterior applications, where exposure to environmental elements is inevitable. In architectural paints, for instance, the inclusion of TIO2 not only beautifies structures but also prolongs their lifespan by combating weathering In architectural paints, for instance, the inclusion of TIO2 not only beautifies structures but also prolongs their lifespan by combating weathering In architectural paints, for instance, the inclusion of TIO2 not only beautifies structures but also prolongs their lifespan by combating weathering In architectural paints, for instance, the inclusion of TIO2 not only beautifies structures but also prolongs their lifespan by combating weatheringchina tio2 used in paint.

  • TiO2 is also used in the production of plastics, where it serves as a whitening agent and UV stabilizer. By incorporating TiO2 into plastic products, manufacturers can enhance their appearance, increase their lifespan, and improve their resistance to sunlight and weathering. Additionally, TiO2 helps prevent the degradation of plastic materials, ensuring that they retain their properties and performance over time.
