Titanium dioxide (TiO2), commonly known as titanium dioxide, has a high refractive index, strong chemical stability, excellent whiteness, the achromatic force and hiding power, and non-toxic, odorless, and is widely used in paints, plastics, paper and ink and other industries. Titanium dioxide products are divided into rutile and anatase two categories; production process there are two kinds of sulfuric acid and chlorination, the chlorination process has a short process, the high degree of automation, less waste, low energy consumption, product quality etc., is the mainstream technology of the developed countries.
In recent years, due to higher profit margins of the titanium dioxide industry, enterprise investment enthusiasm high, and have invested in the construction of titanium dioxide devices, resulting in the rapid increase of domestic titanium dioxide production. In 2014 alone, there are 15 titanium dioxide project put into operation, with production capacity of about 80 million tons, production capacity increased by more than 50%. According to incomplete statistics, there are still under construction, 12of the proposed project, the total capacity of 3.1 million tons, these projects are all implemented as planned, the domestic titanium dioxide production capacity will reach 3.5 million tons in 2015, excess production capacity will further increase . Meanwhile, the new device they use sulfuric acid process, devices and high energy consumption, pollution, products in the low-end and low added value, and thus the ability to resist risks. Serious low-level redundant construction, on the one hand, China's low-end titanium dioxide production capacity has a surplus of enterprises operating rate is less than 80%; the other hand, the high-end products is a serious shortage of production capacity per year will require a lot of imports, high-end market fundamentals were imported product monopoly.
The relevant departments should strengthen the industry to monitor the operation, the timely release of industrial policy-oriented, market supply and demand, production can take advantage of the conditions, industry developments and other information, and actively guide social capital to invest. Industry associations to play a bridging role, guide enterprises to strengthen self-discipline, and implementation of national policies and regulations to promote the industry sustained and healthy development. Development and reform and industrial authorities, we must resolutely implement the industrial restructuring and revitalization plan, as well as the National Development No. 38 spirit, strengthen planning guidance, the use of energy saving and environmental protection standards, improving the access threshold to promote technological transformation, the elimination of backward production capacity .
