Sunresin has developed a series of chelating resins and ion exchange resins to efficiently and accurately treat the water quality that exceeds the standard based on the continuous efforts of R&D team. These resins can be used to realize highly selective and accurate adsorption and removal of characteristic factors in water, and make the treatment of water that exceeds the standard easier and more economical.

Seplite® MonojetTM CM1850 uniform particle strong acid cation exchange resinproduced by advanced "jet granulation" technology after repeated tests and demonstrations. By using the special structural design and functional group setting of the resin, the binding force between the resin and glucose and fructose can be differentiated, and the efficient separation of glucose and fructose can be achieved through the elution of spreading agent according to the degree of difficulty of separation.

On June 24, 2020, the National Property Office of the people's Republic of China announced the list of patent special research projects of 2020, it has 30 projects in total all over the country. Sunresin New Materials Co. Ltd., Xi'an and Sunshine Intellectual Property Group applied for the project of "Patent Analysis and Research on High Performance Adsorption&Separation Materials and Application Key Technologies", and the project successfully shortlisted.

Liu Guozhong, governor of Shaanxi Province and Li Mingyuan, mayor of Xi'an City, visited Gaoling Sunresin Industrial Park, accompanied by district chief Xie Ningyuan on June 28, 2020.

Seplite® Monojet™ SA8500CP uniform particle super gel, strong base anion exchange resinand the Seplite® Monojet™ SC7700CP uniform particle super gel, acid strength cation exchange resin, both of which are special for condensate polishing. They have high compressive strength, high sphericity after osmotic-attrition and grinding and high crosslinking, which greatly improve the treatment performance of condensed water. According to the experimental demonstration and authoritative testing and evaluation, the performance indexes of the above two kinds of monoplus have reached or exceeded the same type of monolus products in foreign countries.

Seplite®LSC-760 Special Resin for Fluoride Removal Makes Wastewater Precision Fluoride Removal Easier Fluorine is one of the trace elements needed by human body, which is mainly accumulated in human bones and teeth. Constant fluorine is helpful to prevent dental caries. However, if the fluorine content in drinking water is more than 1ppm, the teeth will gradually have spots and become brittle; if it is more than 4ppm, it will cause fluorosis, and lead to bone marrow deformity and harm human health. Therefore, the country has clear requirements for fluorine content in drinking water (less than 1ppm). For the discharge requirements of fluorine content in industrial wastewater, some regions have also raised the national discharge standard of less than 10ppm to less than 1ppm, which brings challenges to the precision removal of fluorinein industrial wastewater.

WEDM is carried out in the working fluid medium. The insulation performance of the working fluid plays a role of deionization in the process of pulse discharge, accelerating the cooling of electrodes and workpieces in the process of machining, and making the corrosion products suspended and discharged from the discharge gap. The quality of working fluid will have a great influence on cutting speed, surface roughness and machining accuracy. As a low-speed wire cutting process with high-precision parts, it naturally has higher requirements on the quality of working fluid, which requires deionized water to have lower conductivity (generally, the conductivity is less than 20μs/cm).

Sunresin has developed a new vanadium extraction resin based on its own experience and technology in resin R&D and application process optimization. After industrial verification, compared with conventional anion exchange resin, the resin has higher adsorption capacity and strength, better selectivity for pentavalent vanadium, and more outstanding anti pollution ability, well-received by industry production enterprises.
