"After more than 20 years of rapid development, the scale and product quality of China's titanium dioxide industry have been comprehensively improved, but to achieve high-quality development, it is necessary to increase the research and development of top products, ensure the supply of raw materials, improve industrial concentration, and focus on environmental protection and clean production.
We will make efforts in all aspects
.
Increase the research and development of top products
Increase the research and development of top products Increase the research and development of top productsOver the past 20 years, although China's titanium dioxide industry has made great progress in production and equipment technology, product quality research and development, compared with international companies, there is still a big gap in terms of product brand awareness and quality connotation

Over the past 20 years, although China's titanium dioxide industry has made great progress in production and equipment technology, product quality research and development, compared with international companies, there is still a big gap in terms of product brand awareness and quality connotation
.
In the international market, the titanium dioxide products exported by China are mainly used in the low-end fields, and only some of them can be used in the mid- and high-end fields
.
Bi Sheng said that since 2009, the overall scale of China's titanium dioxide has ranked first in the world
.
Ensure the supply of raw materials for the chlorination process
Ensure the supply of raw materials for the chlorination processBi Sheng said that the transfer of the production process to the chlorination method is one of the development trends of the international titanium dioxide industry in the past 30 years
.
It is understood that before 2019, the proportion of chlorination production in China has always been 2% to 5%; there were originally 4 production enterprises, which were reduced to 2 in 2018
.
In 2019, China's chlorination process has made substantial progress: On the basis of the completion of the first phase of 100,000 tons/year of production capacity, Lomon Billions achieved the first production line of the second phase of 200,000 tons/year project by the end of the year.
It was completed and put into operation, bringing the company's chlorination production capacity to 300,000 tons/year.
After the acquisition of Yunnan Xinli Titanium Industry, the total production capacity reached 360,000 tons/year
.
In addition, on the basis of the existing 60,000-ton/year chlorination process capacity, CITIC Titanium has started construction of a new production line with an expansion capacity of 60,000 tons/year; Shandong Xianghai Resources Technology Co.
, Ltd.
, a subsidiary of Shandong Lubei Chemical Industry Co.
, Ltd.
, has 60,000 tons.
The 50,000-ton/year production line of Sichuan Yibin Tianyuan Haifeng Hetai Co.
, Ltd.
has been put into operation, and the construction of the second 50,000-ton/year production line will be implemented later
.
Bi Sheng reminded that when a new chlorination project is launched, the guarantee of titanium raw materials needs to be considered
.
"In the next 1 to 2 years, the total production capacity of China's chlorination method will reach about 650,000 tons/year, of which the boiling method process capacity will be about 500,000 tons/year
.
The preparation of high-grade titanium raw materials for boiling chlorination in domestic titanium ore also requires Under the background of unrealized industrialization, the titanium raw materials of about 800,000 tons/year required for this 500,000 tons/year production capacity can only rely on imports
.
However, in recent years, the exploration or production of high-grade titanium raw materials in the international market has not been a big deal.
The progress is still showing a downward trend, and it will be an indisputable fact that the supply and demand of titanium raw materials will be tight in the future
.
" Bi Sheng said
.
Increase industry concentration
Increase industry concentrationBi Sheng believes that the decreasing number of producers and the growing scale of a single producer is another development trend of the world titanium dioxide industry
.
In China's titanium dioxide industry, with the rapid development of large enterprises, the status has been continuously consolidated, and the concentration of industry production capacity has been continuously improved, but the shuffling effect is still difficult to appear in the short term
.
It is understood that at present, there are 17-18 titanium dioxide producers in the world except China, with a total production capacity of 4 million tons/year, of which the top 5 are Chemours, Tenor, Panergy, Connors, Ishihara Comprehensive The production capacity is 3.
6 million tons/year, accounting for 90%
.
From a domestic point of view, in 2019, the production capacity of China's top 5 manufacturers accounted for 50%; the top 10 manufacturers accounted for 67.
6%, which is obviously a big gap with foreign countries
.
"In the current relatively loose economic environment, the existing manufacturers still have basic survival conditions, and there are many new projects joined by outside the industry, which makes the total number of titanium dioxide manufacturers not only decrease but increase
.
Considering that Various factors, this situation is difficult to change in the short term, which is also a difficult problem in the high-quality development of the industry
.
" Bi Sheng pointed out
.
Pay attention to environmental protection and cleaner production
Pay attention to environmental protection and cleaner productionBi Sheng said that after more than 20 years of rapid development, China's titanium dioxide industry has made great achievements.
The next stage of development goals is to further improve and improve the existing foundation; Efforts are made in the direction of comprehensive utilization of waste and side effects and low emission or even zero emission
.
At present, special attention should be paid to the purification, treatment and reuse of low-concentration acidic wastewater and low- and medium-concentration waste acids; and before this part of wastewater waste acid is purified and reused, it can only be neutralized with alkaline substances such as lime/carbide slag.
The resource utilization of the generated sludge is a crucial part of realizing the green industry
.
Bi Sheng emphasized that compared with the sulfuric acid method, the chlorination method uses high-grade titanium raw materials, so the solid emissions containing monovalent chloride ions are much less, and the treatment difficulty is much higher than that of the sulfuric acid method.
The solid waste containing divalent sulfate radicals
.
The scale of the existing chlorination enterprises is small, and the solid waste discharged is basically not treated scientifically.
However, after the larger-scale installation is completed and put into operation in the later stage, the tens of thousands of tons of hazardous waste discharged can no longer be ignored or simply treated.
, which is also an urgent problem to be solved in the high-quality development of the industry
.
