FOCUS ON IRON OXIDE PIGMENT PRODUCTION
SANHUAN PIGMENT, COLORFUL WORLD
Titanium Dioxide: Take the Clean Road, Round the National Dream
China has now become a major producer of titanium dioxide. In 2014, the capacity utilization rate of major enterprises was over 90%, and the industry concentration was significantly improved. The quality of domestic titanium dioxide products began to be accepted by the international market. During the “Thirteenth Five-Year Plan” period, the titanium dioxide industry should seize the opportunity of optimizing and upgrading China's economic structure, formulate practical and feasible goals in clean production technology transformation, product structure optimization and mergers and acquisitions, and explore the road to manufacturing titanium dioxide.
Promote cleaner production in the industry
To build a strong manufacturing country of titanium dioxide, clean production is the only way for the titanium dioxide industry. During the “Thirteenth Five-Year Plan” period, the titanium dioxide industry should optimize the production process of sulfuric acid titanium dioxide, carry out clean production technology transformation, improve the “three wastes” governance and control level, and do a good job in environmental protection.
In the exhaust gas treatment angle, it is necessary to increase the exhaust gas treatment device, such as the absorption of sulfur dioxide and the dust recovery device;
In the perspective of wastewater treatment, advanced membrane filtration technology should be used to filter wastewater through special membranes for reuse, thereby achieving the goal of reducing wastewater discharge, saving water and water;
In the perspective of waste treatment, attention should be paid to the treatment of ferrous sulfate and gypsum, a by-product of sulfuric acid titanium dioxide.
Among them, in addition to being directly used as a water purifying agent, ferrous sulfate can also be used as a raw material to prepare iron-based pigments such as iron black, iron red, iron yellow, and the like;
For gypsum, it can adjust the treatment process to produce white gypsum, which can be used in the construction industry such as cement factory; it can also be directly used as gypsum brick for industrial infrastructure and gypsum crafts, thus reducing the massive accumulation of gypsum.
Increase product added value
In 2014, the quality of domestic titanium dioxide products began to be gradually accepted by the international market. At the same time, due to its low price, the export volume of titanium dioxide increased greatly in 2014. This situation is expected to become a new normal in the future.
Under this favorable background, the optimization and adjustment of the structure of titanium dioxide products should start from two angles. First, improve the performance of general-purpose products and increase market share. At the same time, develop professional products to fill domestic vacancies, complete import substitution, and increase Export, do a strong country in the manufacture of titanium dioxide.
The second is to focus on the development of high value-added titanium dioxide, such as titanium dioxide for denitrification, photocatalytic titanium dioxide, etc., to broaden the application of titanium dioxide, looking for a new business opportunity for the production of sulfuric acid titanium dioxide. At the same time, we must pay special attention to the market development of the titanium dioxide industry in new downstream applications, and seek new growth points for the development of the industry.
Expand mergers and acquisitions
In 2014, the top six titanium MCP-T360 white powder producers in the titanium dioxide industry accounted for 40.8% of the country's total output, and the industry concentration was significantly improved. In particular, the marriage of Longyan-Yililian injected new vitality into the industry. . During the "13th Five-Year Plan" period, reorganization and merger is still an important issue in the industry. Establishing a company with great development potential and cultivating a brand with world influence are part of the industry development strategy during the 13th Five-Year Plan period. To this end, the government is called upon to support the development of chlorinated titanium dioxide technology, and to allow the chlorinated titanium dioxide enterprises to enjoy preferential policies for high-tech enterprises, to appropriately increase the tax rebate policy for export products, and to include the chlorination technology as a manufacturing power plan. Give financial support.
In the next 5 years, the industrial chain design of the titanium dioxide industry should follow the overall process technology route and product development strategy of the titanium dioxide industry. Guided by national policies, support and develop the chlorination titanium dioxide project, increase single-line capacity and overall production capacity; promote the clean production process technology of sulfuric acid process, complete large-scale production capacity, and form multiple titanium dioxide with an annual output of more than 300,000 tons. enterprise.
The implementation of titanium dioxide industry standards and policies and regulations, the continued improvement of sulfuric acid titanium dioxide production technology, and the encouragement of chlorination titanium dioxide production technology, all contribute to the advantages of China's titanium resources and industry capacity. During the "Thirteenth Five-Year Plan" period, building a world of titanium dioxide manufacturing is a goal that the industry is striving for.
