In the past two years, under the rigorous environmental protection, China's titanium dioxide industry not only promotes the upgrading of product structure and technology, but also pays attention to energy conservation and emission reduction and environmental protection. It is a common practice to clean production, protect the environment and achieve sustainable development. The clear tasks proposed by the national “13th Five-Year Planâ€.
Titanium dioxide has a wide range of applications, but the development of China's titanium dioxide enterprises is still subject to many factors. From the current situation, China's titanium dioxide enterprises must achieve transformation and upgrading, product structure and technology upgrades, must strengthen pollutant prevention, strengthen the recycling of waste acid water in the industry's dominant sulfuric acid process, and take sustainable recycling economy The road to development, the second is to break through the key technologies of the chlorination process to adjust from the industrial structure.
Transformation and upgrading is the inevitable road, and it is forced by the big environment! What is gratifying is that China's titanium dioxide industry is working hard, such as: Ningbo Xinfu “Sulfuric acid method titanium dioxide waste acid water comprehensive treatment water saving and emission reduction†device is about to run, after normal operation The technical indicators that can be achieved are as follows:
The acid waste water reduction rate reached 89%;
The water recycling rate reaches 85%;
The recycling rate of efflux sulfuric acid reaches 90%;
The amount of acid-base neutralized lime is reduced by 90%;
The amount of titanium gypsum waste produced is reduced by 90%.
It has achieved the goal of energy saving, emission reduction and recycling economy.
Another example: led by the Titanium Dioxide Association, Nanjing Yifu Technology Co., Ltd. independently developed and designed the "Industrial by-product gypsum comprehensive utilization" technology, and has successively cooperated with Panzhihua Government (vanadium and titanium park), Panzhihua Oriental Titanium Industry, Yunnan Dongpu and other titanium dioxide enterprises. Exchanges are expected to be implemented in the near future.
Industry product upgrades are also in full swing. Recently, the “Ink-specific Titanium Dioxide†independently developed by the Longyan Group, which has just passed the appraisal, has been developed. The production of “Lithium Titanate Battery Materialsâ€, which will be launched by Jiangsu Fanhua.
The production scale of chlorination method has gradually expanded, Longli, Yibin Tianyuan and Hubei Xiantao Electronics. During the “Thirteenth Five-Year Plan†period, the ratio of China's chlorinated titanium dioxide production to sulfuric acid method titanium dioxide production will gradually reach 20% of the industry's “13th Five-Year Planâ€.
The transformation and upgrading of China's titanium dioxide industry is imperative. The general trend is to seize the opportunity. The constant is the "crisis" and the change is the "opportunity".
