The working principle of ultrapure water machine: the ion exchange of ultrapure water machine is a special kind of solid adsorption process, which is carried out by the electrolyte solution of the ion exchange agent. The general ion exchanger is a solid granular substance insoluble in water, i.e. ion exchange resin. It is capable of drawing a certain cation or anion from the electrolyte solution, and exchanging another ion with the same charge sign contained in itself in equal amount and releasing it into the solution, which is called ion exchange. According to the type of exchanged ions, ion exchangers can be divided into two categories: cation exchangers and anion exchangers.
Beijing Zhongxin Jiayi Technology Co., Ltd. is specialized in laboratory research and development, production, sales and service in one of the technology company, the company's ZX-70 ultrapure water machine in the ion exchange resin using hydrogen ion exchange cations, and hydroxide ions exchange anions; to contain sulfonate styrene and styrene dioxide made of cation exchange resin will be exchanged with hydrogen ions encountered in the cations (e.g., Na+, Ca2+, Al3+). Similarly, an anion exchange resin made of styrene containing a quaternary ammonium salt exchanges various anions (e.g., Cl-) encountered with hydroxide ions. Hydrogen ions released from the cation exchange resin combine with hydroxide ions released from the anion exchange resin to produce pure water.
