On March 22-24, the 21st Annual Meeting of China Polyurethane Industry Association and The 2023 China Polyurethane Industry Development Forum was held in Shanghai. During this period, the reporter of Tiantian Chemical Network had the honor to interview Mr. Jiang Zhiguo, a professor of materials science at Beijing University of Chemical Technology, and talked with him about the new research and application of polyurethane, and actively discussed the current situation of the integration of production and research in my country’s polyurethane industry and the future high-quality development of the industry.
Thirty years of unremitting efforts Cultivate and explore new frontier applications of polyurethane
Reporter from Tiantian Chemical Network: Please briefly introduce your work in the field of polyurethane research direction and work.
Professor Jiang Zhiguo: First of all, thank you for your interview and your attention to the polyurethane industry. Since I started working in 1987, I have been engaged in the research and development of polyurethane materials for nearly 35 years, involving polyurethane adhesives, polyurethane coatings, polyurethane elastomers, polyurethane foams and polyurethane fibers. The main research direction focuses on the application of polyurethane materials in new fields, such as high-speed railways, nuclear power plants, pumped storage power plants, aerospace and medical fields, etc.
Time changes and needs change Follow up to reform the old and innovate first
As the “fountain of life” of the polyurethane industry, scientific research plays a role in promoting the improvement of material performance , application expansion and sustainable development of the green cycle, its importance is self-evident. Over the years, thousands of scientific researchers have searched up and down, brought forth the new through the old, and constantly illuminated the way forward for polyurethane with innovative results. As one of them, Professor Jiang actively shared his latest scientific research progress in the field of polyurethane.
Reporter from Tiantian Chemical Network: About the research project you are currently promoting , what innovative progress? What fields can these innovative achievements be applied to, and what kind of development prospects do they have?
Professor Jiang Zhiguo: In the past five years, the national development model has been quietly changing, and the demand for polyurethane has also occurred There have been major changes, and more demands have emerged. For example: the construction of elastic power grids is in full swing, and the construction of pumped storage power stations is speeding up, among which there are many applications for new polyurethane materials. We have developed “polyurethane three-proof (waterproof, anti-seepage and anti-icing) coating” and MS plastic water-stop material, which are used in the construction of rockfill face dams. Its outstanding technical index is that the water absorption rate is less than 0.1%, and it can be used for “long-term wading”. It can not only meet the construction of power station reservoirs, but also help the technical progress of the waterproof industry. It is estimated that the total domestic market size can exceed 1 billion yuan per year.
Reporter from Tiantian Chemical Network: Compared with SR and GB plastic sealing materials , could you please elaborate on the innovations of MS plastic sealing materials?
Professor Jiang Zhiguo: SR plastic filler is a sealing material made of asphalt, black, viscous, and Elastic paste, SR plastic filler is used as water-stop material for the surface of rockfill dams, SR plastic filler can also be used as caulking water-stop material for other concrete and building concrete joints, the main material of SR plastic filler is Ding Based on putty, SR plastic filler has good plasticity and is easy to construct, so it is used in many projects.
GB plastic packing is chlorinated butyl rubber sealing material, specially for concrete panels , Rockfill dam peripheral joint water stop and expansion joint water stop, a new type of flow type caulking water stop material developed and produced, is the key material for surface water stop of face dams, and can also be used as joints of other concrete buildings Surface caulking material.
MS plastic packing is a silicone sealing material, which is specially designed for rockfill face dams The outstanding advantages of the new water-stop material developed are: low temperature resistance, and can be used in an environment of -45°C. Long life, stable material for a long time (50 years), wide temperature range use.
Reporter from Tiantian Chemical Network: The FEVE anti-ice pull-out you developed this time Can the coating be applied in the scene of different material structures (for example: concrete structure, wood structure & steel structure, etc.)?
Professor Jiang Zhiguo: At present, it can only be applied to rock-fill face dams in cold regions.
Reporter from Tiantian Chemical Network: As we all know, scientific research does not happen overnight, as in the past Bi, what challenges do you think the current scientific research in the field of polyurethane needs to face?
Professor Jiang Zhiguo: The factors that determine scientific research are “needs, funds, personnel, systems and environment” five elements. Before the reform and opening up, we mainly lacked “funds, personnel, systems and environment”, so scientific research was difficult, and scientific research activities were limited to the national level; today we only lack “needs”, and scientific research activities have been distributed to a large number of enterprises. Looking into the future, it is now the spring of scientific research. Scientific research activities will sprout and grow in the vast industrial sectors like “grass”. I believe that in the future, major scientific research achievements will be nurtured.
High-quality development prospects are bright The two worlds join hands to develop a grand vision
Reporter from Tiantian Chemical Network: With circular economy and “double carbon” With the goal proposed, it is the trend of the times for the polyurethane industry and its upstream and downstream to implement the new development concept of innovation, coordination, green, openness and sharing, and to implement innovation-driven and green development strategies. What do you think of the road prospect of “double carbon” in the polyurethane industry in the future?
Professor Jiang Zhiguo: Everyone has a different perspective and must have different views on major policies. “Double carbon” is the general trend, the direction is clear, but the channels can be different. The polyurethane industry has penetrated into all aspects of life. Polyurethane has many advantages such as low energy consumption in processing, long service life, good heat preservation and energy saving. More application of polyurethane materials can achieve the goal of double carbon.
Reporter from Tiantian Chemical Network: Frontier technology has become the wind vane of the polyurethane industry. As a scholar, what do you think of the current situation in which academia and experts from various enterprises in the polyurethane industry have established production-research integration and cooperation, collaborated with enterprises to educate people to promote technological innovation, and help industrial transformation? Do you have any suggestions for this?
Professor Jiang Zhiguo: There is an essential difference between science and technology. It is to do a good job of unknown products. The purpose of the work is different, the inspection method is different, and there is a natural difference between the two. Some science can be transformed into technology, and some science can be transformed into “magic”. All technology comes from science, and all science may not produce technology. Scientists and technical workers should support each other. It is recommended that the polyurethane industry seek solutions (not production technology) from the scientific community, and it is also recommended that scientists seek research inspiration from the industry. Scientists and technicians in the polyurethane industry need to work together to fight a “cooperative battle”. Realize the sharing of resources and achievements, accelerate the transformation of achievements, enhance the international competitiveness of my country’s polyurethane industry, and promote the high-quality development of the polyurethane industry. In addition, the introduction of doctoral education in engineering indicates that education will become the link between science and technology in the future, and the national science and technology innovation will also usher in a new wave of development.
