Dongying DuPont Titanium Dioxide Project

The technology used must also be from DuPont, right? Domestic technology research and development is facing further pressure! It must be GDP causing this again!

What is titanium dioxide used for? ? Has it become excessive? I remember that Shandong Dongjia Group also produces titanium dioxide

This is a method used by foreign companies to control global titanium resources! Be careful!

DuPont’s titanium dioxide technology is world-class, but the technology used in the Dongying project is not worth recommending.

Having read Southern Weekend’s coverage of this incident, I believe it is not just a matter of competition. If we are always afraid of foreign companies entering and thus triggering competition, then domestic technology will never be able to develop (it must be admitted that international chemical companies do indeed have advanced technologies). The key question is whether such factories will cause changes to the surrounding environment and have an impact on local residents. According to Southern Weekend, DuPont’s technology itself poses significant environmental risks, as some waste needs to be buried deep underground; however, experts are not sure what effects this will have. Moreover, this project was also attempted in Taiwan in the past, but it was abandoned due to opposition from local residents. In short, I don’t think this is a good thing.

Domestic companies are not afraid of competition; it’s simply that the technology adopted by DuPont in China generates waste amounts that are several times higher than those produced by high-quality raw materials, and this waste is unusable. In China, there is only one enterprise that produces titanium dioxide in chloride form – Panzhihua Iron and Steel Group Jinzhou Titanium Industry Co., Ltd. After more than a decade of research and development, this company has now basically mastered the technology for producing titanium dioxide in chloride form; many of the key performance indicators have reached or come close to the levels achieved by foreign companies. This represents the hope for technological advancement in China.

I’ve heard that there is a considerable amount of waste generated from titanium dioxide, and some of the pollutants are radioactive. Additionally, some of these pollutants need to be buried deep underground. I hope that, for the sake of our future, we will handle this issue with caution; we shouldn’t ignore other aspects just because of GDP considerations. If that’s really the case, then we have no choice but to leave Dongying.

Titanium dioxide has stable chemical properties and generally does not react with most substances. In nature, titanium dioxide exists in three crystal forms: anatase, rutile, and brookite. The plate titanium form is an unstable crystal form with no industrial value. The anatase form, abbreviated as type A, and the rutile form, abbreviated as type R, both possess stable lattices; they are important white pigments and components in ceramic glazes. Compared to other white pigments, they offer superior brightness, coloring power, coverage, weather resistance, heat resistance, and chemical stability – and most importantly, they are non-toxic. Titanium dioxide is widely used in industries such as coatings, plastics, rubber, inks, paper, chemical fibers, ceramics, personal care products, pharmaceuticals, and food. The coating industry is the largest consumer of titanium dioxide, especially rutile titanium dioxide, with the majority of it being used in the coating industry. Paints made from titanium dioxide feature vibrant colors, high coverage, strong coloring power, low usage requirements, and a wide range of options. They provide protection against degradation by various media, enhance the mechanical strength and adhesion of the paint film, prevent cracking, block the penetration of ultraviolet rays and moisture, and thus extend the lifespan of the paint film. The plastics industry is the second-largest user. Adding titanium dioxide to plastics improves their heat resistance, light resistance, and weather resistance, enhances their physicochemical properties, strengthens their mechanical strength, and prolongs their service life. The paper industry is the third-largest user of titanium dioxide, which is used as a filler in paper, primarily in high-quality and thin papers. Adding titanium dioxide to paper gives it better whiteness, a good gloss, high strength, a thin and smooth texture, prevents penetration during printing, and results in a light weight. Titanium dioxide used in papermaking is generally untreated anatase titanium dioxide, which can act as a fluorescent brightener to increase the whiteness of paper. However, laminated paper requires surface-treated rutile titanium dioxide to meet the requirements for light and heat resistance. Titanium dioxide remains an essential white pigment in high-quality inks. Ink containing titanium dioxide remains color-stable over time, has good surface wettability, and is easy to disperse. Titanium dioxide used in the ink industry comes in both rutile and anatase forms. String 3: The textile and chemical fiber industry is another important application area for titanium dioxide. Titanium dioxide for synthetic fibers is mainly used as a matting agent. Since anatase is softer than rutile, anatase is generally used. Titanium dioxide used in synthetic fibers generally does not require surface treatment, but certain special grades need to be surface-treated in order to reduce the photochemical effects of titanium dioxide and prevent the fibers from decomposing under its photocatalytic action. Titanium dioxide is used in the rubber industry as a coloring agent, as well as for reinforcement, anti-aging, and filling purposes. Titanium dioxide is added to white and colored rubber products, providing resistance to sunlight exposure – preventing cracking and discoloration – as well as high elongation capacity and acid-alkali resistance. Titanium dioxide for rubber is mainly used in automobile tires, as well as rubber shoes, rubber flooring, gloves, sports equipment, etc., and is generally in the anatase form. However, for the production of automobile tires, a certain amount of rutile-type products is often added to enhance ozone and ultraviolet resistance. Titanium dioxide is also being used more and more widely in cosmetics. Since titanium dioxide is non-toxic and far superior to lead white, it is used in almost all powders to replace lead white and zinc white. Adding only 5%-8% titanium dioxide to the perfume powder is sufficient to achieve a permanent white color, while also making the perfume smoother and giving it better adhesion, absorption, and covering power. In gouache and cold creams, titanium dioxide can reduce the greasy and transparent feel. Titanium dioxide can also be used in various other spices, sunscreens, soap bars, white soaps, and toothpaste. The porcelain glaze produced from titanium dioxide has high transparency, and it features a low weight, strong impact resistance, good mechanical properties, vivid colors, and resistance to contamination. Titanium dioxide for food and pharmaceutical use is titanium dioxide with very high purity, low heavy metal content, and strong covering power.

Dioxins are generated in the production of titanium dioxide, and dioxins are highly carcinogenic substances.

We firmly oppose the construction of this project in Dongying; we hope that those in power will leave behind to future generations this unique and youngest land in the Yellow River Delta

They still proceed with it when titanium dioxide pollution is so severe.

At present, China’s titanium dioxide industry relies on the sulfuric acid process for production, which causes significant pollution; Dongying DuPont uses the chlorination process, resulting in relatively less pollution. In China, there is only one plant using the chlorination method in Jinzhou, and its operation is far from satisfactory. Technology still needs to be introduced!

Titanium chloride white requires high-quality titanium slag, and the production of titanium slag involves manufacturing synthetic rutile using the hydrochloric acid method, or producing enriched material via the sulfuric acid method. Primary products are highly polluted.
