As a food additive, titanium dioxide and its nanoparticles in particular have been associated with DNA damage and cell mutations, which in turn, have potential to cause cancer. When used as a food coloring, it is known as E171.
For instance, in paints, the particle size affects hiding power and durability, while in food colorants, purity is paramount to ensure safety and compliance with regulatory standards For instance, in paints, the particle size affects hiding power and durability, while in food colorants, purity is paramount to ensure safety and compliance with regulatory standardstitanium dioxide is prepared from suppliers.Variations of titanium dioxide are added to enhance the whiteness of paint, plastics, and paper products, though these variations differ from the food-grade ones for things we eat (1Trusted Source, 2Trusted Source).
Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies.[2] The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength.[3] Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.[1]
Door: flat door, sliding door and folding door

2. Sliding door has simple operation and smooth sliding; it is convenient to divide and effectively use the space of the house; it has a good sound insulation effect; it is conducive to the light and transparency of the overall indoor space.
3. Folding door
After the folding door is opened, it can be moved to the side. The room is more transparent and will appear broader. It has the functions of heat preservation and heat insulation, moisture-proof, fire-proof and flame-retardant, noise reduction and sound insulation.
Aluminium windows are distinguished by their excellent resistance to weathering. Their surface is anodised, which guarantees effective protection against corrosion. In addition, the material is resistant to rapid changes in temperature, which allows it to remain ductile without expanding under the influence of heat. This ensures comfortable use all year round, regardless of the weather conditions.
Overall, door sliding rollers play a crucial role in the functionality of sliding doors. Without them, the door would not be able to move smoothly along the track, making it difficult to open and close. By investing in high-quality sliding rollers and properly maintaining them, you can ensure that your sliding doors will continue to operate smoothly for years to come. So next time you admire the sleek look of a sliding door, remember to thank the humble door sliding roller for making it all possible.
