Una de las funciones más importantes de los chocks es brindar estabilidad. Durante el proceso de laminado, las fuerzas ejercidas sobre el metal pueden ser extremas. Los chocks aseguran que los rodillos permanezcan en la posición correcta, evitando desplazamientos que puedan afectar la calidad del producto final. Además, una alineación inadecuada puede provocar una distribución desigual de la presión sobre el metal, lo que puede resultar en defectos o incluso en daños a la maquinaria.

  • 5. Is EFSA banning titanium dioxide? 

  • Another vital aspect to consider when working with a lithopone pigment pricelist is the effect of quality on pricing. Higher purity pigments generally command a premium price because of their enhanced performance characteristics. When choosing a supplier, it’s essential to look for manufacturers who adhere to strict quality control standards. This ensures that the pigment not only meets industry standards but also performs reliably in various applications, thus justifying any additional costs.


  • In the realm of advanced materials, the production of high-quality 30-50nm TiO2 (Titanium Dioxide) powders has emerged as a pivotal aspect of nanotechnology. These ultrafine particles exhibit unique optical, photocatalytic, and semiconductor properties, making them indispensable in a wide array of industries, from cosmetics to solar panels. The manufacturers who specialize in this niche domain are the backbone of this innovative sector.

  • A dense, white, opaque pigment composed of a mixture of Zinc sulfide (30%) and Barium sulfate (70%) with trace amounts of Zinc oxide. Lithopone, first produced in 1874, was called Orr's white. The mixture of the two components is so intimate that it is hard to distinguish microscopically. Lithopone is an inert, transparent pigment which is often used as a filler or as a base for lake pigments. Lithopone was widely used in house paints in the first half of the 20th century. It was also used for some artist grounds, inks and as a filler in Paper, Leather, and Linoleum. Now lithopone has mostly been replaced by Titanium dioxide.

  • Moreover, Chinese manufacturers are acutely aware of the international demand for sustainable practices
  • One of the primary uses of titanium dioxide is as a pigment in cosmetics and personal care products. It provides a natural, white color to products such as foundations, powders, and lipsticks, making them look more appealing to users. Additionally, titanium dioxide has excellent UV protection properties, which help protect the skin from harmful sun rays. This makes it an essential ingredient in sunscreens and other skincare products.
  • EFSA's evaluation is related to the risks of TiO2 used as a food additive, not to other uses.

  • Titanium dioxide is a widely used pigment in various industries, including paint, plastics, and paper. It is known for its excellent opacity, brightness, and UV-resistance, making it a popular choice for manufacturers looking to enhance the quality and durability of their products.

  • One of the main concerns about TiO2 in water supplies is the potential for nanoparticles to leach into drinking water sources from consumer products that contain TiO2, such as sunscreen and toothpaste. While the concentration of TiO2 in these products is typically low, there is still a risk of exposure through ingestion or inhalation While the concentration of TiO2 in these products is typically low, there is still a risk of exposure through ingestion or inhalation While the concentration of TiO2 in these products is typically low, there is still a risk of exposure through ingestion or inhalation While the concentration of TiO2 in these products is typically low, there is still a risk of exposure through ingestion or inhalationtio2 in water suppliers.

  • Other experts say there is simply no conclusive evidence at this point that titanium dioxide is damaging to humans after ingesting. Kaminski in particular said the research studies cite health hazards that were found by using high doses of the product, which you would not normally see in food.

  • In conclusion, titanium dioxide rutile manufacturers play a vital role in the production and supply of this essential pigment to various industries. By focusing on quality, sustainability, innovation, and customer relationships, manufacturers can meet market demands, drive growth, and contribute to the overall success of the titanium dioxide rutile industry.

  • A great number of other brands with fancy names have gone out of the German market, because of some defects in the processes of manufacture. The English exporters, as a rule, offer three or four grades of lithopone, the lowest priced consisting of about 12 per cent zinc sulphide, the best varying between 30 and 32 per cent zinc sulphide. A white pigment of this composition containing more than 32 per cent zinc sulphide does not work well in oil as a paint, although in the oilcloth and shade cloth industries an article containing as high as 45 per cent zinc sulphide has been used apparently with success. Carefully prepared lithopone, containing 30 to 32 per cent sulphide of zinc with not over 1.5 per cent zinc oxide, the balance being barium sulphate, is a white powder almost equal to the best grades of French process zinc oxide in whiteness and holds a medium position in specific gravity between white lead and zinc oxide. Its oil absorption is also fairly well in the middle between the two white pigments mentioned, lead carbonate requiring 9 per cent of oil, zinc oxide on an average 17 per cent and lithopone 13 per cent to form a stiff paste. There is one advantage in the manipulation of lithopone in oil over both white lead and zinc oxide, it is more readily mis-cible than either of these, for some purposes requiring no mill grinding at all, simply thorough mixing with the oil. However, when lithopone has not been furnaced up to the required time, it will require a much greater percentage of oil for grinding and more thinners for spreading than the normal pigment. Pigment of that character is not well adapted for use in the manufacture of paints, as it lacks in body and color resisting properties and does not work well under the brush. In those industries, where the paint can be applied with machinery, as in shade cloth making, etc., it appears to be preferred, because of these very defects. As this sort of lithopone, ground in linseed oil in paste form, is thinned for application to the cloth with benzine only, and on account of its greater tendency to thicken, requires more of this comparatively cheap thinning medium, it is preferred by most of the manufacturers of machine painted shade cloth. Another point considered by them is that it does not require as much coloring matter to tint the white paste to the required standard depth as would be the case if the lithopone were of the standard required for the making of paint or enamels. On the other hand, the lithopone preferred by the shade cloth trade would prove a failure in the manufacture of oil paints and much more so, when used as a pigment in the so-called enamel or varnish paints. Every paint manufacturer knows, or should know, that a pigment containing hygroscopic moisture does not work well with oil and driers in a paint and that with varnish especially it is very susceptible to livering on standing and to becoming puffed to such an extent as to make it unworkable under the brush. While the process of making lithopone is not very difficult or complicated, the success of obtaining a first class product depends to a great extent on the purity of the material used. Foreign substances in these are readily eliminated by careful manipulation, which, however, requires thorough knowledge and great care, as otherwise the result will be a failure, rendering a product of bad color and lack of covering power.

  • In Europe, the downstream paints and coatings sector presented weak demand in front of the titanium dioxide manufacturers, and thus, the titanium dioxide price trend experienced a gradual decline in its trajectory. Additionally, the pressure of inflation and increasing bank interest rates lowered the spending appetite of consumers which had an adverse effect on the titanium dioxide price trends. Further, the export and import of titanium dioxide were also caught under the negative influence of the poor economic conditions of the market.
