With a large pickpocket used for steel wire, into the zinc liquid before the surface of the zinc ash stirring; Use a small outlet for galvanized steel wire; Zinc pot steel wire outlet in 30 minutes, with pickpockets back and forth, until the large, floating zinc residue into brown, real zinc ash, zinc ash surface. The extracted zinc ash should be brown yellow real zinc ash, zinc surface, effectively reduce zinc consumption.

4. Cooling: The galvanized steel wire needs to be cooled to reduce its temperature to room temperature.

In a study published in the journal Food and Chemical Toxicology in 2016, researchers investigated whether titanium dioxide exposure led to an increase in colorectal tumor creation in mice by using a colitis associated cancer model. By measuring tumor progression markers, the researchers found that mice given titanium dioxide experienced enhanced tumor formation in the distal colon.  There was also a decrease of cells that act as a protective barrier in the colon. The researchers wrote: “These results suggest that E171 could worsen pre-existent intestinal diseases.”

The agency makes this exception for several approved color additives. 

In food, titanium dioxide is often used as an artificial color additive. Tasha Stoiber, senior scientist at the consumer health nonprofit Environmental Working Group, says titanium dioxide can generally be thought of as a paint primer – it often goes on a hard-shelled candy like Skittles before the color is added to give it a uniform shine.

Main products are titanium dioxide LR-982, titanium dioxide LR-108, titanium dioxide LR-996, LR-895 and other products.

Report Overview:

Lithopone 30% has a lower coverage power than titanium dioxide. For this reason, Lithopone 30% can only partially substitute titanium dioxide, between 5 and 40%. 

Application of lithopone in rubber and plastics application of lithopone in plastics and pigments lithopone can whiten and improve the compressive strength of products. Lithopone is easy to disperse rapidly, and thus the production process of this product is convenient, especially the molding, injection molding and actual operation process. It is worth mentioning that, with its organic chemical plasticity, it can also be integrated into the vulcanized rubber effect of recycled rubber.

In a study published in 2022 in the journal Particle and Fibre Technology, researchers examined the impact of maternal exposure to titanium dioxide nanoparticles in newborn offspring mice. They found that “a chronic exposure to TiO2 NPs during pregnancy alters the respiratory activity of offspring, characterized by an abnormally elevated rate of breathing.” Breathing was also shown to be “significantly and abnormally accelerated,” and the ability for neural circuitry to effectively adjust breathing rates was impaired. The researchers concluded: “Our findings thus demonstrate that a maternal exposure to TiO2 NPs during pregnancy affects the normal development and operation of the respiratory centers in progeny.”

Infrared analysis showed that the characteristics bands for the bare nanoparticles are still exhibited in the vitamins@P25TiO₂NPs spectra, such as a wide peak in 450–1028 cm⁻¹ related to the stretching vibration of Ti-O-Ti and other peaks in 1630 cm⁻¹ and 3400 cm⁻¹, which represent the surface OH groups stretching. The IR spectrum of vitaminB2@P25TiO₂NPs showed signs of binding between compounds. The OH bending peak (1634 cm⁻¹) corresponding to bare nanoparticles disappeared, and the NH₂ bending band characteristic of vitamin B2 appeared (1650 cm⁻¹). The IR spectrum of vitaminC@P25TiO₂NPs also showed signs of successful functionalization. Bands at 1075 cm⁻¹; 1120 cm⁻¹; 1141 cm⁻¹ were observed, which are originated by CO-C vibrations present in the vitamin C. The intense band at 1672 cm⁻¹ is attributed to the C = O stretching in the lactone ring while the peak at 1026 cm⁻¹ is ascribed to the stretching vibration Ti-O-C. Wide bands at 3880–3600 cm⁻¹ are related to stretching vibration OH groups, but those disappear in the modified nanoparticles spectrum. These observations confirm the interactions between the P25TiO₂NPs and the vitamins [35].

In 2021, the European Food Safety Authority concluded that titanium dioxide is no longer safe in foods due to the same concerns over nanoparticles. As a result, titanium dioxide is now banned as a food additive in the EU. Although studies have shown that the absorption of ingested titanium dioxide is low, evidence suggests that titanium dioxide nanoparticles can accumulate in the body over time. Health Canada deemed it safe in 2022 but noted concerns. Unlike their European counterparts, Canadian officials did not consider studies performed with titanium dioxide nanoparticles alone. 

Titanium dioxide has many purposes in both food and product development.

The company was established in 1989. Its predecessor is the titanium dioxide factory, a secondary independent accounting production unit affiliated to CNNC 404. It is a high-grade rutile with an annual output of more than 10,000 tons that imported advanced foreign technology and key equipment earlier in my country. It is also a high-quality titanium dioxide supplier in my country earlier in the market. After years of development, the company now has three production bases in Jiayuguan, Gansu, Baiyin, and Maanshan, Anhui.

As of August 7, the use of titanium dioxide in food is banned in the European Union. Europe is taking a precautionary principle approach based on findings from the European Food Safety Authority (EFSA).
