Application of ultrapure water equipment in the LED industry

With the development of science and technology, LED products in our lives are becoming more and more diversified, and their applications are becoming more and more extensive. From computer LCD screens to LCD TVs to the touch screen mobile phones we carry with us, LEDs have become our lives. It is an indispensable part of the work, but dust will affect the surface of the display during the production of the display, so it is necessary to clean the surface with high purity ultrapure water. The editor of Hualanda will mainly introduce ultra-pure water treatment equipment for cleaning LCD screens, its technological process, characteristics and applications.

The ultrapure water treatment equipment for cleaning the LCD screen adopts fully automatic control, and the water quality of the effluent is energy-saving and environmentally friendly. The raw water is municipal tap water or groundwater first enters the water tank for precipitation, and is preliminarily purified by the pump booster and pretreatment system. Multi-media filters can remove large particles of impurities in raw water. Activated carbon filters and water softeners remove rust, chemicals and water hardness. The security filter is worthy of its name to protect the RO device. It absorbs inorganic salts through the RO membrane to the intermediate water tank and booster pump. Finally, through the EDI system (or mixed bed device) in the main engine and the precise microporous filter, the pure water reaches the standard.

The equipment uses an EDI module device without waste acid and waste lye, and the amount of ion exchange resin is less than 50% of the traditional process. The effluent quality of ultra-pure water can reach international standards, and the standards for pure water in the United States, ASTM, Germany, Japan and other countries. Ultra-pure water equipment for cleaning LCD screens is a supporting production of high-tech electronic products. Pure water directly determines its actual effect after cleaning.

Pure water is also used in the production of semiconductor materials and integrated circuits, and water for cleaning LCD liquid crystal displays, PDP plasma displays.
