Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Progress in Chemical Engineering Equipment】Regular updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Recently, 12 sets of G5 electronic-grade isopropanol production equipment, designed and manufactured by Tianhua Institute, were successfully applied in CNPC’s first high-end electronic-grade IPA production system, where they achieved stable and high-level production performance. The project achieved a successful first run in July 2025, and qualified products were produced in September of the same year. Tests conducted by authoritative institutions confirmed that the product specifications met all the requirements of the G5 grade for electronic-grade isopropanol. In early 2026, high-purity isopropanol was introduced to the South Korean market, and the monthly production and sales volume of the facility exceeded 1,000 tons for the first time; the quality of the product received high praise from overseas customers. The electronics industry is a **strategic emerging industry; achieving independent research and development as well as self-control over key electronic chemicals, and breaking free from reliance on foreign technologies, is crucial for enhancing the core competitiveness of the electronics industry chain. G5-grade electronic-grade isopropyl alcohol serves as a core fundamental material for advanced processes in the electronics industry, such as precision cleaning, etching, and photoresist removal. Its purity and cleanliness have a direct impact on the performance and reliability of electronic components, making it an essential key ingredient in advanced manufacturing processes such as those used in semiconductors and display panels. Compared to conventional chemical products, electronic-grade chemicals impose extremely strict requirements on production process control, equipment materials, equipment design and manufacturing processes, clean manufacturing, and surface treatment techniques. Tianhua Institute focuses on the key objectives of removing metal ions and achieving process parameters at the 10ppt level. Through structural design and innovations in equipment technology, it addresses the issue from the design stage itself, preventing the precipitation of metal ions and impurities and eliminating ion contamination during the production process. This ensures the ultra-high purity and stable performance of the products, providing a solid technical foundation for maintaining G5-grade product standards over the long term, and successfully overcoming the challenges posed by a lack of appropriate equipment technology and restricted manufacturing processes. The successful commissioning of this project represents an important milestone for Tianhua Institute in transitioning from the manufacturing of traditional industrial-grade equipment to that of high-end electronic-grade equipment. It provides strong support for the company’s efforts to enter the field of electronic chemicals equipment and to implement its strategy aimed at achieving higher levels of sophistication in its products. Looking to the future, Tianhua Institute will keep pace with the development needs of **strategic initiatives and the electronics chemicals industry. It will continue to advance technological innovation and equipment upgrades, offering higher-standard solutions and more stable, reliable complete sets of equipment. In this way, it will strengthen its core competitiveness in the field of high-end electronics chemicals equipment, contributing to the high-quality development of this industry.
