The acceptance team consisting of 11 nationally renowned experts in domestic fluorine materials, membrane preparation and chlor-alkali equipment has recently visited the Shandong Dongyue Group's ion membrane production equipment and the first 10,000-ton chloralkali electrolyzers for domestic ion membrane equipment. It was agreed that the four key topics of perfluorinated membrane technology, perfluorinated membrane enhancement materials, perfluorinated ion exchange membrane engineering technology, and fuel cell membrane electrode key technology research have fully fulfilled the assessment criteria, and the perfluorinated membrane prepared. To reach the international advanced level of similar products. In the process of research and development of the project, a total of 172 invention patents were filed (of which 7 were international patents) and 44 had been authorized.
The expert group pointed out that China's chlor-alkali industry scale and actual production ranks first in the world and support the rapid development of China's national economy. However, the key component of the ionic membrane process chlor-alkali process, the production technology of perfluorinated membranes, was monopolized by foreign countries and was China's chemical industry. There are major hidden dangers in the safe operation of industry and even the entire national economy. Researching the technology of perfluorinated ion membrane engineering with independent intellectual property rights and realizing the localization of perfluorinated ion membranes is a major problem that China's chemical industry is eager to solve for 30 years. Shandong Dongyue Group and Shanghai Jiaotong University implemented a marriage between schools and enterprises in 2003. In May 2004, the perfluorinated ion exchange membrane material research project was listed as a major project of the “863 Program†by the state; in September 2005, the ion membrane project was listed as a high-tech No. 1 project in Shandong Province, which supports the entire province; In December 2006, the research of perfluorinated membrane engineering technology was listed as a major project of the national "Eleventh Five-Year Plan" technology support plan. With the strong support of the Ministry of Science and Technology and the Shandong Science and Technology Department, with the joint efforts of the chemical industry, the project team successfully completed the perfluorinated membrane production line on September 22, 2009, and the 1.35-meter-wide industrial-scale perfluorinated membrane succeeded. The line broke the foreign monopoly in one fell swoop; on June 30, 2010, Dongyue ion membrane was successfully applied to 10,000 tons of chlor-alkali equipment and became a milestone in the development of China's chlor-alkali industry.
Dongyue Perfluorinated Ion Membrane All Dates Accepted by the State
The "Eleventh Five-Year" National Science and Technology Support Program Shandong Dongyue Group's four projects for major projects of perfluorinated ion exchange membrane engineering technology have all passed acceptance by the Ministry of Science and Technology. The key technologies for domestically produced perfluorinated membranes, engineering amplification technology and equipment technology, which were listed as the High-Tech No. 1 Project in Shandong Province, were successfully applied on the 10,000-ton electrolyzer, breaking the long history of the chlor-alkali industry in China.
