2022 China Nuclear Energy High Quality Development Conference took place from 15-17 November in Shenzhen World Exhibition & Convention Center. Scientific research institutes, industry associations, operators, service providers, regulators in the field, as well as specially invited experts and scholars, gathered together to discuss the development and opportunities of China's and the world's nuclear power industry.
As a leading company in the ion exchange resin industry, Sunresin New Materials Co. Ltd. (SZ 300487), was invited to participate at the event showcasing its latest products and solutions, with focus on its Monojet® series of uniform particle resins, uranium extraction resins, nuclear-grade resins for the removal of radioactive elements, UPW-grade ultrapure water resins, condensate polishing resins, nuclear-grade water treatment resin, etc.
The Seplite uniform particle resins independently developed by Sunresin can be used for nuclear reactor’s primary circuit purification and chemical control of other systems. Testing results have shown that indicators have reached international standards.
Monojet®, Sunresin's Seplite Uniform Particle Resins
Monojet®, Sunresin's jetting technology independently developed has realized the stable production of uniform particle resin. The electronic-grade Monojet® resin has a high transformation rate, excellent dynamic performance, low TOC escape and outstanding mechanical strength, and is especially suitable for ultrapure water production for the panel and chip production.
After more than half a year of on-site commissioning and stable operation, the quality of the terminal outlet water has fully met the application requirements of electronic grade ultrapure water (resistance>18.22MΩ·cm, TOC<1 ppb, D.O.<1ppb). A number of commercial orders have been signed with high-end UPW customers.
The adsorption and separation technology that Sunresin is engaged in is a highly efficient separation and purification platform technology with strong environmental friendliness, high automation, and good operational accuracy. As a leading global company in the adsorption and separation technology industry, we have been actively considering how to integrate our more than 20 years of research and development accumulation and technological advantages in the field of adsorption and separation with the national carbon neutrality path to contribute to the achievement of the dual-carbon goals and help optimize and upgrade downstream application processes.
Sunresin has developed Uniform Particle Ion Exchange Resin using targeted research and development, advanced chromatographic equipment, and strict quality control, utilizing new synthetic biology technology. This resin is designed to address the impurities and high salt content of existing fermentation processes used to produce ergothioneine. It is used for chromatographic desalination, decolorization, and purification, achieving an inorganic/organic salt removal rate of over 95% in high salt systems, reducing conductivity to below 50μs/cm. Moreover, the uniform particle characteristic of the resin allows for lower pressure drop in the resin bed, larger online liquid processing capacity, lower resin breakage rate, and better impurity and salt removal compared to conventional resins. This results in higher yields and significantly improved production efficiency, while reducing production costs.
To meet the high requirements of enterprises for fluoride content in wastewater and residents' demand for fluoride-free drinking water, Sunresin's research team has continuously researched, developed, and improved targeted adsorption fluoride removal resins LSC-760 and LSC-860 based on the typical industry wastewater quality and treatment process characteristics.
