Domestic titanium dioxide industry: technology is theirs, pollution is ours.

industry seminar held in Luhe City, Henan Province, on the one hand, let the whole industry see the dawn of upgrading, on the other hand, but let the public see the annual output value of millions of tons of titanium dioxide industry behind, because of the long-term monopoly of foreign technology and hidden huge pollution hidden.
the vast majority of the public, titanium dioxide, regarded as the foundational material of the industry, is an unfamiliar field. But "First Financial Daily" reporter found that it is this is not well-known products, but determines our entire survival, life.
As the world's third largest inorganic chemical product after synthetic ammonia and phosphoric acid, titanium dioxide is widely used in
coatings
,
paints
, plastics, paper, ink, fiber, rubber, cosmetics, food and other fields, as well as pure titanium, glass and glass ceramics, electrical ceramics, catalysts, electrical conductors and other fields.
coatings, plastics, for example, the composition of the entire coating, 60% are composed of titanium dioxide; In plastics, titanium dioxide also accounts for up to 20% of the composition. Even many women often use cosmetics, all contain high-grade goldstone nano-titanium white powder, this titanium white powder is added to sunscreen, lipstick, foundation, makeup powder and other products, to play a role in shielding UV protection of the skin.
data show that in 2013, China's actual production of titanium dioxide has exceeded 2 million tons, up to 2.155 million tons, an increase of 14% year-on-year, accounting for about one-third of the global total, has exceeded the United States for several years, becoming the world's largest producer and consumer of titanium dioxide. Moreover, with the acceleration of the process of urbanization in China, the production and consumption of titanium dioxide in China is still rising.
is regrettable, with the rapid development of the entire titanium dioxide industry, but behind the hidden high pollution, high consumption and low efficiency.
data from the titanium dioxide industry branch of the China Coatings Industry Association show that for every ton of titanium dioxide produced by traditional sulphuric acid, 100 to 150 tons of fresh water is consumed, and the overall energy consumption is about 1.6 tons of standard coal, but also will produce a concentration of 20% of the waste sulfuric acid 8 tons, acid wastewater 100 tons, waste slag 8 tons, as well as sulfur dioxide, acid fog and dust exhaust gas 25,000 cubic meters.
's how shocking it is to be behind these figures? Industry insiders in a comparable caliber calculation, the domestic titanium dioxide industry per million yuan of output value of industrial wastewater emissions, exhaust gas emissions, sulfur dioxide emissions, respectively, the chemical industry average of 3.85, 1.03, 2.13 times, is the corresponding indicators of all industrial industries 3 to 8 times.
hundreds of domestic titanium dioxide manufacturers, most of the manufacturers used precisely has been widely eliminated by other countries sulfuric acid production technology.
the lingering pollution hidden dangers, has become the whole titanium dioxide industry's biggest regret.
there any better technology? National Chemical Industry Productivity Promotion Center Titanium White Branch Center Director, Titanium White Powder Industry Technology Innovation Strategy Alliance Secretary-General Bi Sheng said, in fact, looking at the world, sulphuric acid method due to environmental and economic reasons, has been a technology being phased out, the United States as early as 2006 closed the last sulfuric acid method titanium dioxide powder factory, and instead all the use of short process, device production capacity, high degree of automation, product quality, waste and emissions of less chlorination production technology. It is estimated that the cost of treating traditional sulfuric acid pollutants is as high as 1900 yuan per ton of products, while the cost of chlorination is only 800 yuan per ton of products.
more than 90% of China's titanium dioxide manufacturers still use sulphuric acid technology, which has been abandoned by the world.
Why this is the case, Li Maoen said, one of the important reasons is that the more advanced chlorination technology, for a long time, have been mastered in the United States DuPont and other European and American titanium dioxide manufacturers, these manufacturers joined forces to engage in technical blockade, dead do not sell technology to Chinese manufacturers.
However, with the increasing importance of Chinese titanium dioxide in the global market in recent years, some foreign manufacturers have also begun to actively cooperate with domestic manufacturers, among them, Panyu titanium industry to the United States Pofumens company to provide titanium chloride production process technology, began to build 100,000 tons of titanium chloride production line; Global
Coatings Network
learned that the company paid 105 million technology transfer fees to PPG Industry at the expense of its purchase of chlorinated titanium dioxide production process, also began to build 100,000 tons / year of chlorinated titanium dioxide production line, other such as long-term titanium industry, Yunnan Metallurgical Group has also invested heavily in the production of titanium dioxide production line.
but surprisingly, in the end, this was blocked by European and American manufacturers for many years of chlorinated titanium dioxide production technology, and finally by the private enterprises headquartered in Weihe Xingmao titanium industry to take the lead.
On the afternoon of December 22nd, at the above-mentioned seminar held in Luhe, titanium dioxide experts, including Bisheng, finally judged that Xingmao titanium industry chlorination technology is in line with industrial policy, with domestic leading, international advanced light pollution, the effect is obvious and so on.
Li Maoen, chairman of Xingmao Titanium Industry, said that in order to overcome this technology, once for the lack of funds troubled enterprises have introduced JIANB International, Oriental Fuhai and other 7 venture capital as equity units, even so, the capital still has a gap of 1.5 billion yuan, for this reason, they will actively use innovative financial means, through the issuance of bonds, the introduction of PE investment, strategic cooperation and corporate listed companies and other ways to raise funds.
