Dongyue Group Launches New-Generation Chlor-Alkali Ion-Exchange Membrane DF2809
2025-9-26
The promotion conference for Dongyue¡äs new-generation chlor-alkali ion-exchange membrane DF2809, which has attracted much attention from the chlor-alkali industry, kicked off on September 23. As the first customizable and dedicated ion-exchange membrane, the new DF2809 chlor-alkali ion-exchange membrane from Dongyue has not only established a stable quality assurance system but also injected a more energy-saving, more stable, and more efficient "Chinese core" into China¡äs chlor-alkali industry. This marks that the core technology of domestic chlor-alkali ion-exchange membranes has reached the world¡äs advanced level, which will promote the chlor-alkali industry to enhance its international competitiveness and step into a new stage of green development and high-end trend.
Zhang Wenlei, President of China Chlor Alkali Industry Association and Song Xiangdong, head of the provincial chlor-alkali association, leading officials from the city and county as well as relevant competent departments such as Li Xinsheng, Zhang Liangyun, Wang Hongbo, and Chen Zhiyuan, and Group leaders like Zhang Jianhong and Wang Weidong, together with 141 customer representatives from 71 companies in the chlor-alkali industry, gathered together to witness this highlight moment of domestic high-end chlor-alkali ion-exchange membranes.
Zhang Wenlei, President of China Chlor-Alkali Industry Association (CCAIA), highly recognized Dongyue¡äs significant contributions in the R&D, production and application of domestic ion-exchange membranes. He said that chlor-alkali ion-exchange membranes are an important guarantee for the safety of the chlor-alkali industry, and their localization is crucial to ensuring the security of the national industrial chain. Since Dongyue undertook the national key scientific research task of developing ion-exchange membranes for chlor-alkali use, its R&D team, under the leadership of Chairman Zhang Jianhong and Chief Scientist Zhang Yongming, has made unremitting innovations for 23 years and achieved a major leap from technological breakthroughs to iterative upgrades. The newly released DF2809, with its reliable quality and differentiated applications, has become an important milestone in the advancement of Dongyue¡äs ion-exchange membrane technology and the chlor-alkali industry¡äs competitiveness. In the future, CCAIA will guide the entire industry to focus on green, low-carbon, and intelligent development, and promote the overall technological progress and improvement of the chlor-alkali industry.
Zhang Yongming, Chief Scientist of Dongyue Group and Director of the National Key Laboratory of Fluorinated Functional Membrane Materials, elaborated on the core technological breakthroughs and competitive advantages of DF2809 in detail, and pointed out that the success of the new-generation chlor-alkali ion-exchange membrane stems from four key supports. He said that in the future, the R&D team will rely on the National Key Laboratory to make efforts in two directions: on the one hand, closely follow market demands to continuously develop membrane products with higher performance; on the other hand, strive to reach new heights in the chlor-alkali industry by developing ion-exchange membranes for waste salt resource utilization, so as to solve the major problem of severe ecological and environmental pollution caused by 20 million tons of waste salt per year in China, and commit to building an internationally leading source of chlor-alkali ion-exchange membrane technology.
This promotion conference was hosted by Li Yuwen, Deputy Secretary of the Group Party Committee and Vice President. In his concluding remarks, he mentioned that the new-generation chlor-alkali ion-exchange membrane DF2809 covers the technological advantages and strengths of DF2807 and DF2808 as it has made new progress in key indicators such as chlorine gas purity and tolerance, and established a new system with stable quality and performance. Customers choose Dongyue¡äs ion-exchange membranes not only because they are "Chinese-made membranes" but more importantly, in the future, through the strategic cooperation model of annual orders and dedicated membranes established with customers, Dongyue will create more and greater value for customers. After gaining an in-depth understanding of the performance of Dongyue¡äs new-generation chlor-alkali ion-exchange membrane DF2809 and its strong supporting systems for scientific research, testing, production, and services, all guests were impressed by the development achievements of Dongyue¡äs chlor-alkali ion-exchange membranes and hold high expectations for the newly launched DF2809. Amid the current complex market operations, this has further strengthened the confidence in industrial chain cooperation.
