The requirements for water quality of precision machinery industry:
In the precision machinery trade usually needs 10uS/cm-0.1uS/cm (ultra) pure water or pH above 9.5 alkaline waters to clean the accessory, especially when the pH of the alkaline water is above 9.5 can clean the accessory does not need detergent . So it has big economical efficiency and good for environmental protection.
Application occasion:
Production and processing of the car spare part;
Production and processing of plane, car engine;
The laboratory;
Production and processing of printer, fax-machine laser;
Production and processing which reads and writes magnetic head and disc
of optical drive, hard disk;
The accessory of engine;
