全球最大！盐城造深海耐压玻璃球舱打破国外垄断

Core Viewpoint - The successful development of a 23-inch deep-sea pressure-resistant glass sphere by Yancheng Huida Glass Instrument Co., Ltd. marks a significant advancement in China's autonomous capabilities in deep-sea exploration equipment, filling a gap in both domestic and international markets [1][8]. Group 1: Product Development - The deep-sea pressure-resistant glass sphere is essential for underwater detection, requiring high transparency, pressure resistance, and corrosion resistance [3]. - This type of high-end product has been dominated by foreign companies, with domestic efforts historically facing performance limitations and a lack of mature production capacity [3]. Group 2: Company Background - Yancheng Huida Glass Instrument Co., Ltd., established in 2011, is a private enterprise known for its technical expertise, with over half of its employees being skilled technicians [5]. - The company has a history of collaboration with the Chinese Academy of Sciences, having previously developed a low-background glass shell for photomultiplier tubes, which received high praise from academic experts [5]. Group 3: Collaborative Efforts - In June 2022, a joint task force was established, led by academician Cao Zhen, to address the urgent need for core equipment in the high-energy underwater neutrino telescope project, with Huida Glass being the preferred partner due to its past performance [7]. - Over three years, the team underwent numerous technical iterations, culminating in the successful production of a sample in January 2023 and passing a 50Mpa pressure test in May 2023 [7]. Group 4: Impact and Future Prospects - The successful development of this product represents a breakthrough for China in the field of large-size deep-sea pressure-resistant glass spheres, providing solid support for the country's deep-sea exploration efforts and advancing the marine power strategy [8].
