  • The composition of hot dip galvanizing layer is composed of hot dip galvanizing layer, which is composed of iron zinc alloy between iron matrix and surface pure zinc layer. The shape of the workpiece is formed by the iron zinc alloy layer in hot dip, so that the iron and pure zinc layer touch outstanding. When the iron workpiece is immersed in a molten zinc solution, the initial zinc and iron (body) are formed at the interface. This is a crystal made up of zinc atoms in the solid metal iron. When two metal atoms are fused together, the gravitational force between the atoms is very small.

  • There are three methods to detect the thickness of zinc layer of galvanized wire: weighing method, cross section microscopy method and magnetic method, among which the first two experiments will cause certain damage to galvanized wire, including the length of galvanized wire and the reduction of dosage. The general detection of galvanized wire galvanized layer is detected by magnetic method, which is also a more intuitive and convenient method. The standard of galvanized layer thickness is related to the wire diameter of galvanized wire. The larger the wire diameter of galvanized wire, the thicker the galvanized layer is. It is the thickness of galvanized layer and cast iron after centrifugal separation.

  • A legal additive in the United States, titanium dioxide is used in everything from food to consumer goods and the U.S. Food and Drug Administration says regulated use of the product as a color additive in food is safe within certain restrictions.

  • Titanium dioxide, also known as titanium(IV) oxide or simply TiO2, is a white inorganic compound that has become an essential material for various industries. As a chemical compound, it possesses unique properties that make it highly valuable in numerous applications, ranging from paint manufacturing to sunscreen production.
  • We've used titanium dioxide safely for decades. However, recently its safety was called into question. 
     
    At CRIS, we've explored the safety of titanium dioxide for nearly half a decade, including conducting double-blind research to test the safety of food-grade titanium dioxide (E171). Our study shows that when exposed to food-grade titanium dioxide in normal conditions, research animals did not experience adverse health outcomes.
     
    It's important to emphasize that in a National Institutes of Health study, experimental animals were exposed to titanium dioxide in amounts as high as 5% of their diet for a lifetime and showed no evidence of adverse effects. 
     
    A handful of studies greatly influenced the decisions made by the European Food Safety Authority (EFSA). Unfortunately, these studies did not consider that titanium dioxide exposure comes from food, not drinking water. Additionally, CRIS researchers could not reproduce the adverse outcomes identified by the studies through typical food ingestion. Regardless, the EFSA banned E171 as a food ingredient and for use in other capacities in the summer of 2022.
     
    In 2022, the United States, United Kingdom, and Canada maintained that the scientific evidence supports that titanium dioxide (E171) is safe for humans to use and consume.
