According to Zhang Yuehong, chairman of Dongyue Group, according to different uses, ion membranes can be divided into chlor-alkali ion membranes, fuel cell membranes, vanadium cell membranes, hydrochloric acid electrolyte membranes, special electrolytic water membranes, and other ion membranes. At present, Dongyue is carrying out a series of research and development of perfluorinated membrane function according to its scientific research plan.
Perfluorinated membrane is the core material of China's chlor-alkali industry and fuel cells, and is known as "the crown pearl of the chemical industry." The perfluorinated membrane is not only the key material for the electrolysis of ion-exchange membrane alkalis, but also the key material for the future use of new energy. Whoever wins it will be able to grasp the strategic high ground in the era of new energy. Now Dongyue Group has finally stood at this commanding height.
Previously, perfluorinated membranes have been monopolized by the United States and Japan, and the perfluorinated membranes used in China rely on imports. The market price is more than RMB 10 million per ton. Perfluorinated membranes have become an obstacle to the safe operation and healthy development of China's chlor-alkali industry. Technical bottlenecks. To this end, China has successively included it in the national "6th Five-Year Plan" and "Seventh Five-Year Plan" research projects. In January 2004, after the initial breakthrough in the Dongyue Ion Membrane Project, the Ministry of Science and Technology urgently initiated the national "863" plan to support it. After two years of scientific and technological research, the project successfully passed the acceptance inspection at the national level, and a series of key technologies were highly evaluated by acceptance experts.
However, from mastering core technologies to achieving industrialization, it is a difficult progress. For this reason, the state launched the "Eleventh Five-Year Plan" science and technology support plan to support the industrialization of chlor-alkali ion membranes. Shandong Province also identified the Dongyue Ion Membrane Project as the province's high-tech “No. 1 Projectâ€, giving the province its strength to support its industrialization. With the support of all parties, Dongyue Group has integrated technology and human resources, and finally achieved industrialization of ion membranes. Industrial ion membranes have been successfully rolled out.
According to the reporter’s understanding, under the current background of the international energy crisis, all countries are actively developing new energy that can replace oil and natural gas. Hydrogen energy has been regarded as the most ideal energy source for replacing automobile oil and natural gas in the future. Prior to this, Dongyue has successfully developed a fuel cell membrane that has an important impact on the development of fuel cell vehicles.
Domestic chlor-alkali use ion membrane successfully offline
Just after the Spring Festival, the reporter learned from Shandong Dongyue Group that it was learned that after 8 years of research on key technologies and industrialization, Dongyue chlor-alkali was successfully tested with an ion membrane industrial device, and industrial ion membranes went offline. This means that foreign decades of technical monopoly in this field has finally been broken, and China's chlor-alkali industry has since stood a new starting point.
