The EDI ultrapure water equipment used in electronic optics adopts a continuous electric desalination technology that integrates electrodialysis technology and ion exchange technology. Its working principle is to achieve directional migration of ions in water through the selective permeation of cations and anions by cation and anion membranes, as well as the exchange of ions in water by ion exchange resins, and then achieve deep purification and desalination of water.
Ion exchange trees can achieve continuous regeneration through water electrolysis. The hydrogen ions and hydroxide ions generated during the water electrolysis process continuously regenerate the loaded resin, and no alkali or acid chemicals need to be added for regeneration throughout the entire water production process of the equipment.
The effluent quality of EDI ultrapure water equipment used in electronic optics needs to reach:
1. The requirements of enterprises for the effluent quality of equipment;
2. Code for Design of Relay Protection and Automatic Device of Power Equipment (GB50062-1992);
3. Code for Grounding Design of Industrial and Civil Electrical Installations (GBJ65-1983);
4. ZBG98020-90 "Series Spectrum of Water Treatment Equipment";
5. GB/T11446.1-1997 National Electronic Grade Ultra Pure Water Standard Grade I ≥ 18M Ω/CM (25 ℃) for 95% or more of the time;
As is well known, the electronic optics industry, which commonly uses integrated circuit chips, electronic reagent water, electronic tube coating and liquid preparation water, packaging water, liquid crystal display screen cleaning water, optical lens cleaning water, microelectronics industry, microelectronics industry, and various electronic device production water for semiconductor equipment processing in daily life, has extremely high water quality requirements. In this article, let's learn about the EDI ultra pure water equipment used in electronic optics.
