The status quo of China's titanium dioxide industry analysis
At present, China only Pan Jin Titanium titanium dioxide production Medical titanium supplier company uses chlorination technology , all the rest of sulfuric acid production . Titanium dioxide as a very important industrial additive widely used in various kinds of industrial production , which can be used as a coloring agent in rubber , but also because it does not have any toxicity , but also used in cosmetics , meanwhile, is also used produce enamel , as well as non-toxic colors delicious GR composite titanium dioxide pigment
In recent years, enterprises in order to improve the production capacity of titanium dioxide , in addition to plant expansion , but also actively adopt new technology and new equipment. Technical aspects of the production uses : pre-mixed acid hydrolysis process ,titanium foil for sale the vacuum crystallization technology , plus seed hydrolysis technology , membrane filter press is used to replace Moore leaf filter washing process , the rotary kiln exhaust heat for waste acid concentration process , etc. ; equipment technology is adopted : Raymond replaced with air swept mill grinding machine titanium , V = 130m3 large acid solution tank and v = 110m3 hydrolysis reactor utilization , disk filter centrifuge is used instead of ferrous separation , F = 200m3 large leaf filter and membrane filter press for a wash , (1) 3200 × 53000mm rotary kiln applications , rolling mill for grinding rutile titanium dioxide instead of Raymond crude , spray drying or flash drying instead of belt drying machine , DcS control technology, etc. , ultrafine mill which improves production efficiency and the level of production of white control devices , improved product quality , a significant reduction titanium wire price of raw material consumption and energy consumption , so that the whole enterprise technological level a certain upgrade and enhance the company 's competitiveness in the market . However , the concern is that the vast majority of improvements to enhance the technical level limited equipment units and local units of large-scale operations , while supporting the overall optimization of integrated innovation and technology is still insufficient production line , resulting in a performance with the domestic production line a large gap still exists abroad compared .
