On December 1, Fang Hongwei, Secretary of the Xi'an Municipal Party Committee, led a delegation to visit Sunresin New Materials Co., Ltd at the Sunresin Campus.
Accompanied by Dr. Gao Yuejing, chairwoman of Sunresin, Fang Hongwei and the delegation visited Sunresin’s provincial functional polymer adsorption/separation technology research center, the protein purification laboratory, the cell culture lab, and the electronic grade ultrapure water test line. Dr. Gao also gave a detailed introduction to the company's achievements in R&D investment, talent building, technological innovation, as well as its efforts in ensuring a safe working environment facing the pandemic.
Fang Hongwei highly recognized Sunresin’s continuous technological innovations and achievements as a high-tech business, and encouraged the company to increase investment in scientific and technological innovation, enrich the R&D talent team, accelerate the transformation of scientific and technological achievements, and continue to enhance the core competitiveness of the company, while keeping up the the good work in Covid prevention and control.
Since its establishment, Sunresin has been committed to the industrialization of adsorption and separation technologies and has successively developed products and processes for critical applications such as metal extraction, synthesis and purification in life science, and production of ultra-pure water . Through continuous innovation in materials, equipment and processes, Sunresin has been able to turn technological innovations to major breakthroughs in a number of downstream applications such as new energy, environmental protection, and ultra-purification, laying a solid foundation for development of the company, both domestically and internationally.
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.
