COMCESS Nuclear Grade Ion Exchange Resin Series
Nuclear-grade ion exchange resin is widely used in the nuclear power industry. This ion exchange resin has very high purity standards and can meet the strict water quality requirements of the nuclear power industry. Nuclear-grade ion exchange resin is a high-purity ion exchange resin that must undergo special processing and transformation methods. The preparation requirements of nuclear-grade ion exchange resin are much higher than those of ordinary ion exchange resin.
Introduction
Nuclear-grade ion exchange resins are mainly in the form of microspheres. They are mainly divided into two categories: cation exchange resins and anion exchange resins.
Cation exchange resins are made of styrene and divinylbenzene containing sulfonic acid groups. The hydrogen ions carried by the sulfonic acid groups can exchange with all cations they come into contact with. Anion exchange resin is made of styrene and divinylbenzene containing quaternary ammonium groups. The hydroxide ions on the quaternary ammonium groups can be exchanged with various anions they come into contact with.
The term "nuclear-grade" specifically refers to the extremely high quality standards of ion exchange resins, originally used exclusively in nuclear power plants. To ensure consistent quality and guaranteed effluent quality, nuclear-grade ion exchange resins are typically not regenerated.
