Strong Acid Cation (SAC) resins are polymer made by polymerizing styrene and divinylbenzene and sulfonating with sulfuric acid.
The Weak Acid Cation (WAC) resins are copolymerized by acrylonitrile and divinylbenzene and hydrolyzing it with sulfuric acid or Sodium hydroxide.
Strong Base Anion(SBA) resins are polymer made by polymerizing styrene or acrylic acid and divinylbenzene and chlorination, amination.
Weak Base Anion(WBA) resins are polymer made by polymerizing styrene or acrylic acid and divinylbenzene and chlorination, amination.
Dongli ready to use mixed bed resins are specially prepared high quality resin mixtures designed for direct purification of water.
Dongli's wide range of chelating resins contain special functional groups that gives these resins superior selectivity for specific target metals.
Dongli's adsorbent resins are synthetic spherical beads with defined pore structure, polymer chemistry and high surface area used for purification and selective extraction of target molecules in aqueous solutions.
Dongli's Inert/Spacer resins are used to create a barrier in an ion exchange bed and keep the ion exchange beads exactly where they are supposed to be.
application
Water Treatment
Industrial water softening is a process that utilizes ion exchange resins to reduce the concentration of calcium and magnesium ions. These alkaline earth metals can cause scaling and insolubility problems in the everyday uses of water by forming calcium and magnesium carbonate scales.
Hydrometallurgy
