According to the different requirements of the industry, different weights of alloy ingots are put in the smelting furnace according to the standard, such as weaving, Ming, paper, lang, silicon, etc., and the data out of this smelting is called gold ore iron. Iron has gray iron, white iron and the above-mentioned gold, they have different characteristics, so in the industry according to their different characteristics to transport and selection. For example, in gray iron, its carbon exists in iron ore in graphite condition, the crack is often gray, soft and strong, simple filtering, suitable for casting.

Two is to pay attention to the storage and use of galvanized wire products, according to the actual environmental standards to choose different specifications of galvanized wire products;

According to the galvanized iron wire manufacturer, galvanized iron wire is the selection of excellent low carbon steel, through drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes. Galvanized iron wire should pay attention to the following points in the use process:

Until relevant toxicological and human exposure data that would enable reliable risk assessment are obtained, TiO₂ nanoparticles should be used with great care.

The European Commission banned titanium dioxide as a food additive in the EU in 2022 after the European Food Safety Authority (EFSA) conducted an updated safety assessment of E171 and concluded the panel could not eliminate concerns about its genotoxicity. 

However, some experts and food regulators in other countries disagree – pointing to potential, serious health consequences and rising concerns about the additive. Starting August 7, for example, the use of titanium dioxide in food will be banned in the European Union.

It’s particularly useful in sunscreen as it has impressive UV resistance and helps block the sun’s UVA and UVB rays from reaching your skin (6Trusted Source).

Studies suggest that people are more likely to buy and eat foods that are brighter or more vibrant in color. And titanium dioxide is one way to make that happen. You can find it in food products like candy, coffee creamer, baking and cake decorations, and white sauces.

2. Barite calcination method A solution of barium sulfide is prepared. The sulfuric acid and zinc oxide are reacted, purified by adding potassium permanganate and zinc powder, and compressed to obtain a zinc sulfate solution. Then, the prepared barium sulfide solution is mixed and subjected to a metathesis reaction to obtain a mixture of zinc sulfide and barium sulfate, and then the precipitate is subjected to pressure filtration, calcination, wet grinding, drying, and pulverization to obtain a zinc white product.

Titanium dioxide is an insoluble mineral, meaning it cannot dissolve in water. Known for its bright, white pigment, manufacturers use titanium dioxide in many different capacities, including in cosmetics, foods, and drugs. 

What's the Verdict?

Why all of a sudden is there so much interest in the safety of Titanium Dioxide?

Researchers from France and Luxembourg gave E171 (the much more food friendly name for Titanium Dioxide) in Europe and the United States, to lab rats in their drinking water for 100 days.

Of those rats, 40 per cent of the exposed rodents developed “preneoplastic lesions” or precancerous growths. The Titanium Dioxide also inhibited the immune systems of the rats and “accelerated” the growth of the lesions. France’s INRA agricultural research institute, which took part in the study, said in a statement.“These results demonstrate a role in initiating and promoting the early stages of colorectal cancer formation,” though it said no conclusion could be drawn about later phases of cancer, or of any danger to humans……….(not till they test it on us!!)

The results of the study were published in the Nature journal Scientific Reports.
