Recently, the electronic-grade phosphoric acid plant of Wengfu Zijin, a subsidiary of China GPC, has successfully achieved a one-time chemical feeding test run. All product indicators are superior to the G1 level of the general standard for wet electronic chemicals, and some key indicators have reached the G3 level.

   To ensure the smooth progress of the test run, Wengfu Zijin, in collaboration with the Group's R&D Center, established a special test run team to make advance plans and implement precise measures. During the test run, the team efficiently coordinated resources, overcame multiple technical bottlenecks and operational challenges, quickly responded to various emergencies, optimized process parameters, and ensured the rapid response and efficient execution of instructions, laying a solid foundation for the successful one-time test run.

   As a key basic material for electronic information industries such as integrated circuits, flat-panel displays, and solar cells, the purity and stability of electronic-grade phosphoric acid are directly related to the performance and yield of downstream products. Currently, the domestic high-end electronic-grade phosphoric acid market has long relied on imports. Wengfu Zijin's achievement of this technological breakthrough not only enhances the independent supply capacity of domestic electronic chemicals but also provides a guarantee for the security of relevant industrial and supply chains.

   In the next step, the project team will systematically summarize the test run experience, formulate a special rectification plan, promote the plant's performance assessment and continuous stable operation, and accelerate the realization of large-scale mass production. This successful test run has laid a solid foundation for Wengfu Zijin to expand the high-end electronic chemicals market and further enhanced the company's competitiveness in the global fine chemical field.
