University-Industry Collaboration

Since the start of cooperation in 2017, the company and East China University of Science and Technology have always adhered to the concept of complementary advantages and collaborative innovation, and have achieved fruitful results in technology research and development and talent cultivation. After nearly a decade of deep cultivation and meticulous work, the foundation of cooperation between the two sides has been continuously strengthened. In 2026, the strategic partnership will be further deepened and a technology development contract will be officially signed. This signing not only fully affirms the achievements of past cooperation, but also marks a new stage in the integration of industry, academia, and research. In the future, we will focus on specific technological breakthroughs, key common issues in the industry, and jointly explore new models for the deep integration of technological innovation and industrial demand, injecting strong impetus into promoting industrial upgrading and high-quality development.

COOPERATION

Tongzhu Laboratory

As a wholly-owned subsidiary of Shanghai Tongzhu Chemical Technology Co., Ltd., Xuchang Tongzhu Environmental Protection Materials Co., Ltd. is fully responsible for the production, quality control and R&D of adsorbents for Shanghai Tongzhu Chemical. The company's adsorbent products are mainly applied in devices such as coke oven gas desulfurization, gas naphthalene, benzene and oil removal, pressure swing adsorption (PSA) hydrogen production, and fluorine purification. After years of R&D and iterative upgrading of adsorbent production technology, the adsorbents provided by the company have been widely recognized and praised by domestic and foreign users. Meanwhile, the company can customize the production of various adsorbent products according to specific market demands, with a total of 9 categories and nearly 50 varieties. Boasting an annual production capacity of 8,000 tons of adsorbents, the company's products are widely used in major iron and steel enterprises at home and abroad.

Quality is the foundation of an enterprise's survival, and precise testing is the core guarantee of quality. To strengthen the quality defense line of activated carbon products and provide customers with more reliable and reassuring products and services, Xuchang Tongzhu has made great efforts to build a professional adsorbent testing laboratory. Equipped with complete testing equipment and a professional technical team, it possesses strong capabilities to independently complete the testing of various basic indicators of activated carbon, building a solid "firewall" for product quality.

Relying on this professional testing laboratory, the company has realized full-process quality control from raw material incoming inspection to finished product delivery. It can independently conduct testing of all basic indicators without relying on external institutions, which not only greatly improves testing efficiency but also ensures the authenticity, accuracy and authority of test results. This is not only the company's rigorous pursuit of product quality, but also a solemn commitment to customer trust.

In the future, the company will continue to deepen laboratory construction, continuously improve testing and R&D levels, and provide solid quality assurance for customers in various industries with more precise testing, stricter standards and higher-quality products, working together to build a path of high-quality development.
