Working principle of ultra-pure water machine

Working principle of ultra-pure water machine: ion exchange of ultra-pure water machine is a special solid adsorption process, which is carried out in electrolyte solution of ion exchanger. The general ion exchanger is a kind of solid granular substance insoluble in water, that is, ion exchange resin. It can absorb a part of cations or anions from electrolyte solution, exchange with another ion with the same charge sign and release it into the solution, which is called ion exchange. According to the types of exchange ions, ion exchangers can be divided into cation exchangers and anion exchangers.

Beijing Zhongxin Jiayi Technology Co., Ltd. is a technical company specializing in the production, sales and service of laboratory R&D. In ZX-70 ultra-pure water machine, ion exchange resin exchanges cations with hydrogen ions and anions with hydroxide ions. The cation exchange resin made of styrene and divinylbenzene containing sulfonate will exchange various cations (such as Na+, Ca2+ and Al3+) with hydrogen ions. Similarly, anion exchange resin made of styrene containing quaternary ammonium salt will exchange various anions (such as Cl-) with hydroxide ions. Hydrogen ions released by cation exchange resin combine with hydroxyl ions released by anion exchange resin to generate pure water.
