To pool efforts in driving industry innovation and empowering technological upgrades, on May 6, 2026, a delegation led by Professor Shen Chunlin, Director of the Suzhou Institute of Waterproofing Materials; Gao Yan, Vice Chairman of the Waterproofing Materials Professional Committee of the China Silicate Society and Chairman of Liaoning Jiuding Hongtai Waterproofing Technology Co., Ltd.; Tian Wenhua, President of the National Grouting and Leak-Stoppage Association and Chairman of Hohhot Yuda Waterproofing Materials Co., Ltd.; and Wang Xuezhen, Chairman of Zhongde Xinya Building Materials Co., Ltd., paid a visit to Zhengzhou Jianwen Special Materials Technology Co., Ltd. for an inspection and a symposium. The delegation was warmly received by Zhang Xuewen, Chairman of Jianwen Technology, and Zhang Shijie, General Manager. Industry leaders engaged in in-depth discussions on topics such as the development of the waterproofing materials sector, the application of new technologies, and market trends, while also laying the groundwork and building momentum for the upcoming Zhuhai Waterproofing Expo on May 18.

Professor Shen and his delegation visited Jianwen Technology’s three core areas—the raw-material warehouse, the CC Control Center, and the R&D Center—conducting on-site inspections to assess the company’s end-to-end process control and innovative capabilities. At the raw-material warehouse, the delegation carefully examined the classified storage of raw materials, the quality-tracing system, and the actual production-use procedures, highly commending Jianwen Technology’s rigorous quality-control framework that ensures product stability by stringent oversight at the source. At the CC Control Center, real-time data monitoring of the intelligent production lines and the automated control systems were clearly visible, vividly demonstrating the company’s precise and efficient digital manufacturing model and its competitive edge in “intelligent manufacturing with quality as the top priority,” which earned unanimous praise from the delegation.

Subsequently, the delegation entered the R&D center to closely examine the company’s flagship new product: an ultra-white belite–sulfoaluminate cementitious binder. During the on-site, direct comparison of the sample’s whiteness and various performance metrics, experts and corporate leaders alike expressed profound admiration. This product boasts a Hunter whiteness of 92, with a pure, refined hue and exceptional whiteness and textural quality—clearly standing out from ordinary comparable products on the market and delivering both striking aesthetics and superior intrinsic performance.

White belite sulphoaluminate cementitious binder, a core innovative achievement of Jianwen Technology (Patent No.: ZL202511121425.2), is a high-tech product that our company’s R&D team has successfully developed through prolonged and intensive research. It integrates the outstanding properties of belite sulphoaluminate with those of various cementitious materials, exhibiting a Hunter whiteness of ≥82. Moreover, it delivers well-balanced and excellent performance across the early, middle, and late stages of curing. After hydration, the resulting products exhibit a highly dense microstructure, characterized by low drying shrinkage, slight expansion, rapid setting and hardening, high early strength, and sustained strength development over time. As such, it is an ideal choice for high-end floor screeds, terrazzo flooring, and decorative architectural elements.

The gathering of leading industry authorities at Jianwen Technology this time not only represents full recognition of the company’s technological prowess and innovative achievements, but also serves as a significant demonstration of industry–university–research collaboration and concerted innovation in the waterproof building materials sector, while laying a solid foundation for participation in the Zhuhai Waterproof Expo on May 18.

As a national-level high-tech enterprise and a provincial-level specialized, refined, distinctive, and innovative SME, Jianwen Technology has been deeply engaged in the R&D and production of specialty engineering materials for more than a decade, consistently regarding technological innovation as its core driving force. The company focuses on developing high-performance sulfoaluminate-based cementitious binders and boasts an annual output of 300,000 tons of specialty engineering materials. Looking ahead, Jianwen Technology will take this exchange as an opportunity to incorporate industry feedback, refine product innovation, and showcase cutting-edge new products—such as white belite sulfoaluminate cementitious binders—at the exhibition. The company aims to collaborate with industry partners, explore new opportunities, empower the waterproofing sector’s high-quality upgrade, and jointly set a new benchmark for architectural waterproofing.
