Post-processing of large castings, large foundry processing manufacturers can use liquid sandblasting to clean the oxide scale and residue on the surface of the casting, which can not only remove impurities, but also play a role in polishing and improving the surface finish of the casting; Use grinding wheels, abrasive cloths, sandpaper and other abrasives to remove impurities such as burrs, protrusions and oxide scales on the surface of steel castings, so that the surface is smooth. In addition, methods such as mechanical, electrochemical and chemical polishing can further improve the gloss and corrosion resistance of castings.

A 20mm drill rod typically refers to a cylindrical tool made of high-strength steel, designed for use in drilling operations. Its 20mm diameter strikes a balance between robustness and manageability, allowing it to penetrate materials while maintaining sufficient structural integrity. The rod can be produced in various lengths, which can be tailored to the specific requirements of a drilling project. Additionally, many manufacturers offer drill rods with various coatings or treatments to enhance wear resistance and durability, making them suitable for use in harsh environments.

  • The global demand for lithopone has been steadily increasing in recent years, driven by the growth of the construction, automotive, and electronics industrieslithopone factory in china. In addition, the increasing awareness of environmental issues has led to a shift towards more sustainable products, which has benefited the lithopone industry. However, the industry also faces challenges such as rising raw material prices and competition from alternative pigments.
  • Tronox Limited is another top TiO2 factory that is known for its premium quality products and innovative technology. With manufacturing facilities in North America, Europe, and Australia, Tronox is a leading producer of titanium dioxide pigments that are used in a wide range of applications, including paints, plastics, and paper. Tronox's TiO2 products are renowned for their superior performance, durability, and color consistency, making them a top choice for manufacturers seeking high-quality pigments.

  • The analysis of the supernatant by UV–Vis spectrometry showed that each gram of P25TiO2NP is loaded with 0.17 g of vitamin B2, after washing them. This value is coherent with the thermogram (Fig. 1), which showed a loss of 19% of weight, attributed to the thermal decomposition of vitamin B2.

  • Prof. Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), wrote of the decision: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive. A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body.”
