In the ultra-pure water preparation and polishing process, high-quality polishing resins with higher processing accuracy, higher purity level and uniform particle size are needed to achieve the purification of water. Sunresin have developed the "jet granulation" technology and uses the world's leading resin production line produced high-purity, high-transformation, uniform-grain H-type cation exchange resin and OH-type anion exchange resin with uniformity coefficient <1.1, which were pre-mixed in a certain proportion and used for the refining treatment at the end of ultrapure water preparation system.

Chelating resin is a kind of cross-linking functional polymer materials which can form multi coordination complex with metal ions. The mechanism of metal chelating resin adsorbing metal ions is that a stable structure similar to small molecule chelates is formed after the coordination reaction between functional atoms on resin and metal ions. The adsorption mechanism of ion exchange resin is electrostatic. Therefore, compared with ion exchange resin, the binding force of chelate resin to metal ions is stronger, which is of high selectivity. It can be widely used in the recovery and separation of various metal ions, the separation of amino acids, hydrometallurgy, pollution prevention and so on.

Sunresin's special treatment resin and package system for waste gas VOCs provide a more cost-effective choice of benzene waste gas VOCs treatment for enterprises in related industries.

Ion exchange system is a kind of traditional water treatment technology which displaces all kinds of anion and cation in water by anion and cation exchange resin. The anion and cation exchange resins can be combined in different proportion to form cation exchange bed system, anion exchange bed system and mixed bed ion exchange system. The mixed bed ion exchange system is usually used to produce ultra pure water and high pure water after water treatment processes such as reverse osmosis. It is one of the irreplaceable means to prepare ultra pure water and high pure water.

Sunresin, began in 2015, Cooperate with enterprises in Yunnan Province that have obtained processing permission for cannabidiol (CBD).
