The inorganic salt industry depends on technological innovation

Affected by the deteriorating economic situation in Europe and the United States and the slowdown in the growth of the domestic economy, the inorganic salt industry has experienced huge fluctuations this year. Most companies in the first half of the year were sunny, but they faced varying degrees of operational difficulties since the second half of the year. At the 2008 China inorganic salt academic and technology exchange meeting that ended on October 17, the participating experts agreed that according to the development of the industry, product mixes should be timely adjusted and optimized, and new technologies and new processes should be used to implement energy conservation and emission reductions to reduce production costs. It will be the only way for the inorganic salt industry to tide over the difficulties.
Ning Yansheng, chairman of the inorganic acid-alkali salt special committee of the Chinese Chemical Society, pointed out that efforts should be made to promote the development of the inorganic salt environmental protection industry and high-tech industries. In the field of environmental protection, it is necessary to vigorously develop clean production integration technologies for heavy pollution products, strengthen waste reduction, resource utilization and safe disposal, and strengthen the development of common technologies for circular economy; promote low consumption, high efficiency and no pollution. Technology, eliminate high energy consumption, low efficiency, heavy pollution, and improve the access threshold for heavy pollution products. In the field of high-tech, nanotechnology, surface treatment technology and inorganic whisker materials should become the focus of industry development.
Experts at the meeting said that in recent years, the domestic inorganic salt industry has successfully developed a number of new technologies and new processes, but many problems still remain to be solved. Traditional inorganic salt products must be modified, highly purified and micronized, and their application value and scope can fundamentally change to become fine, special, and functional materials. Whether it is new products for the development of new and high technologies or the surface activation and refinement of traditional products, in addition to technological innovations, it is also an inevitable requirement to constantly improve the technical level of unit equipment.
In addition, the inorganic salt industry must continue its efforts in scale, centralization, and resource development, and actively promote advanced and applicable technologies. For example, China's self-developed three-phase potassium permanganate process, low-energy large-scale horseshoe flame kiln sodium silicate production technology, the use of two-stage combustion hydration technology to produce phosphate, sodium silicate - phosphoric acid, combined production of sodium tripolyphosphate technology And wet-process phosphoric acid refining technology.
