The functionality of metal expansion nuts centers around the principle of mechanical expansion. Upon the application of torque, the screw or bolt is threaded into the nut, which, in turn, causes the nut to expand outward. This outward expansion presses the sides of the nut against the inner walls of the hole it occupies, creating a tight fit. The added friction and mechanical grip prevent the nut from loosening over time, even in dynamic conditions.

One key aspect that sets 20mm chipboard screws apart is their coating. Most often, they are coated with zinc or a combination of zinc and phosphate, providing resistance against corrosion and increasing their longevity Most often, they are coated with zinc or a combination of zinc and phosphate, providing resistance against corrosion and increasing their longevity Most often, they are coated with zinc or a combination of zinc and phosphate, providing resistance against corrosion and increasing their longevity Most often, they are coated with zinc or a combination of zinc and phosphate, providing resistance against corrosion and increasing their longevity20mm chipboard screws. This coating not only enhances the aesthetic appeal but also protects the screw from rust, especially in humid environments.

  • The Scientific Committee on Consumer Safety issued an opinion of the safety of titanium dioxide in food, stating that it should no longer be considered as safe when used as a food additive.

  • 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.”

  • In conclusion, lithopone 28B301 and 30B311 are versatile pigments with a wide range of applications in various industries. Understanding their properties, applications, and manufacturing processes can help manufacturers make informed decisions when selecting the right pigment for their specific needs.

  • Titanium dioxide, with its chemical formula TiO2, is a naturally occurring compound that has been widely used in various industries due to its unique properties. This versatile white pigment is not only an essential ingredient in the manufacturing of paints, plastics, and coatings but also plays a crucial role in the production of sunscreens, food additives, and cosmetics.
  • no adverse effects on reproduction, development, immune, gastrointestinal or nervous systems, or general health when rats were exposed from pre-conception to adulthood
  • In a preferred technical solution, 3⁄40 2 is added to the Lide powder emulsion of the metathesis reaction step, and the mass fraction of 3⁄40 2 added is 10 to 33%, and the lithopone emulsion is desulfurized (mainly hydrosulfate ion or Elemental sulfur), slowly added 3⁄40 2 until the lithopone emulsion is colorless and transparent. The obtained sulfate ion can be recycled and reused in the production process. The chemical reaction equation is: 43⁄40 2 + HS— + OH— → SO/— + 5H 2 0

  • Anatase, a crystalline form of titanium dioxide, has been garnering significant attention due to its unique optical and electronic properties. This compound is widely used in various applications such as photocatalysts, solar cells, and gas sensors. Given its increasing demand and limited supply, the anatase price has become a topic of interest for both producers and consumers.
  • B301 lithopone is distinguished by its exceptional brightness and tinting strength, making it ideal for applications requiring a crisp, clean hue. On the other hand, B311 offers a subtle difference in terms of shade and opacity, catering to those who prefer a slightly softer yet still highly effective pigment. The nuances between these two grades may seem minor, but they significantly impact the end result, underscoring the importance of precise lithopone selection based on the intended use.
